Dear All
First, let me thank you for providing this excellent forum. I'm new and with your help, I got rid of all the T-Mobile crap on my Wizard and it's running superb after unlocking, installing the Kjam ROM and overclocking. Thank you very very much!
I hope it's the right place posting the following question related to a 1GB miniSD Sandisk card that my Wizard won't regognize anymore. It asks if I want to format upon insertion the card and that's it. The storage card doesn't show up in any of the tools like 'Flash Format', 'Storagetools' and 'Pocket Mechanic'.
Under Windows XP SP2, it also asks if I'd like to format, with the formatting process failing. When inspecting the contents of the card with R-Studio's Hex Editor and '010 Editor' I can see that there's data but there are discrepancies about how much space there's actually available. R-Studio reports it as a 1GB card while 101 Editor reports it as a 7.5MB and 98GB!! card.
Trying to hex edit the card (e.g filling all with 0s with any of the programs fails as everytime I try to save and open the application again my old data shows up again.
I'm not familiar with SD card file systems but sense that something is screwed up with partitions or similar. Is there any sophisticated tool that will just verify/repair/erase/format the card as I have searched for several hours now and all I can find are basic data restore tools that don't do the job? Or is the card beyond help?
Any thoughts and hints are greatly appreciated.
Thanks for sharing your knowledge and thanks for your help and efforts!

sd cards use the same filesystem as hd's do
fat32 fat16 ntfs
i'd say that card is defect
Sounds like you got a card that had it's firmware hacked.
This is common in the Mini-SD market, as 2 Gig cards are commonly hacked to make it look like they are 4 Gig cards. The seller often hacks into the firmware, and makes a change there that makes the card report to the OS that it has a larger size than its capacity acutally is. This is especially prevelant on ebay. If you bought the card from a reputable vendor and it's only a few months old, take it back and tell them you want it replaced. If you didn't, then you are out of luck. Note: Vendors will also do this with 1 G, 512MB, and 256 MB cards. Only buy from someone you trust (in the states I prefer newegg or tigerdirect), and if the price is too good to be true, then trust your instincts and go elsewhere.

Got it from my local Chinese on eBay
Thanks for your thoughts. My bet is that the card has died.
With regards to firmware hacking: I have used it for around six months.
If hacked, will I experience problems straight away or do related problems take some time to surface?
Thanks for your time and efforts!

Normally, they would show up when you tried to exceed the actual limit of the card, not necessarily when you first used the card. Depending on card and other hardware configuration, techincally, you might never find out that you had a "hacked" card until you tried to exceed the card's actual capacity, at which point you'd start getting data errors or "unable to save" errors. Again, the best policy is to buy a card only from a reputeable vendor. Currently, the only 4 Gig cards available are not even available to the the general market, only being made available to hardware or OEM vendors. 2 Gig cards are plentiful, but not all are as advertised. "Caveat Emptor"!
Black-Wolf
tnx for that info black-wolf. i've read about ppl having probs with their 4gb sd so i guess thats the reason.??one question. do this prob affect mini-sd only? what about the 4gb sd???tnx
The problem with 4 Gig cards is mainly with miniSD cards. The vendors on ebay know there is a huge demand for 4 Gig miniSD cards, and the unscrupulous ones will hack the firmware of the card as I said above, and then re-silkscreen the text on the card so it looks like a 4 Gig card, when in fact it is a 2 Gig card. SanDisk is supposed to be releasing their 4 Gig cards to retail soon (sometime this quarter), but again, "Caveat Emptor" if you are not buying directly from them! I wouldn't trust a vendor claiming to have 4 G cards until well after they have been released to retail.
As a final note, any card - SD, miniSD, microSD, XD, CF, etc. - can be hacked firmware wise and made to report its capacity is larger (or smaller - though no one would do that...) than what it actually is. Regardless of where you get your card from, if the vendor has a good return policy (no return fees for bad products, pay for S/H, no restock fees, etc.), then they are probably safe to deal with.

Thanks for your wisdom and time
It has been very educational
Hi, guys
This is a great forum, and I learnd a lot of stuff on this site. Thanks for all your hard work.
I'm a new user of windows mobile and I'm currently with an o2 orbit 2. I have 3 1G cards separately stored applications & co-pilot, music and movies. The question is how i can switch between different storage cards without harming my device. Do i have to switch the device off to change the card, are there any implications for doing that? Cheers.

The Cruise/Polaris's storage card is supposed to be hot-swappable, per HTC the manufacturer. With the price of storage cards going down every day, have you considered buying an 8gb card? I bought one for about $70 with my new Cruise, and now I see them on ebay for $55-60. Good luck...
You can "hot-swap" the µSD card of the o2 Orbit2 (I do ), and, of course, also of the TC.
I bought a 8GB Class 4(!) µSDHC card on ebay.de for 39,95€ (+postal charges)
EDIT: Here: http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=130194411701
thank you for your reply.
I'll use hot-swap for now. And buy a 8G card in a few days.
anything I should be aware of when buying the 8G card?

Personally, I prefer SanDISK brand...
If anyone's interested, I saw an online article somewhere, that stated that sandisk and toshiba both had 16gb microsd cards starting up production, and toshiba actually had found a way to cram 32gb on a card, but sandisk was still working on it. bet we'll all have 32gb cards by next Christmas... Man, back in the early 80's when I had my Atari 800XL, if you'd have told me I'd have 32gb on a portable phone, I'd have laughed at you... heheheee
Seriously. I remember I had a 20 MB hard drive on a 8088/86 computer. That thing was huge and weighed a ton. Now we can have 32 GB on something smaller than my fingernail.
Yeah I have an 8 GB card from amazon for about $60 if i recall correctly. They're definitely worth it.
if you want to use your sd card as some kind of "ram-extender" you may try to get a fast one.
I eg install all programs on my card to have as much ram free as possible, there for I bought the fastest I found.
aleph305, do you notice any difference in speed - can the Polaris take advantage of a faster card? (Perhaps there is a maxspeed)
first : sry 4 the delay.
..
and now. number three, the larch ...
no ... ehm
I guess so.
on a magician I installed pocketplus on the card (noname 2gb @ approx. 12r/5-9w mb/s) and the today screen becomes unusable.
then bought a panasonic 2gb 150X (approx 20-22r/14-18w mb/s) and pocket plus runs like it where at the ram.
Therefore I can confirm that the magician will and Im pretty sure every device will when you use the card as "ram".
ps
- you have never enough ram
- your ram is never fast enough
Hi guys,
I have recently purchased 32gb kingston's class 4 micro sdhc card and encountered a problem with it. Basically the problem is that when I put more than 1.8gb of music on the card everything above that just doesnt get recognised. It is shown in the music player but when you click to play it says "file format is not supported". Another example is if I have 1.8gb of music and try to put a video on the card it says that "format is not supported" aswel. The strangest thing is that it plays music for few seconds then it crashes. At first I thought that it could be a fake memory card but I used h2testw to check the capacity of the memory card and it worked without any issues.
Some screenshots:

Did you let h2testw completely finish? Because it will write all 32GB of data but reading the data is when it finds the problem.

I actually havent I did it up to 12gb gunna let it do it now for whole 32gb. I still think that it is the phone issue. Still ill let it run through out and post the results
You have to let it finish, it'll try and write 32GB since the card is programmed to show 32GB. But really all it's doing is overwriting existing data (if it's fake). So when h2testw starts to read the data, that is when it'll find if your card is real. It'll tell you how much your card can really hold.
If bought from eBay there is a high possibility that it is a fake, unfortunately.
Thanks yvrRome I did let it finnish and it turns out it is fake... it only wrote 1.8gb and the rest was corrupted, this means its fake. This actually good news because this means that its not my phones fault. And Nivki I did bought this from ebay and to make it worse its second time ive been scammed on ebay purchasing 32gb micro sd in a row lesson for me purchase things like these from retail shops
It could also be just a bad card. I would still recommend buying from a retail shop, though.
Newegg now has the Kingston class 4 32gb MicroSD cards for just over $100.
Ebay + Kingston + 32GB + Honk Konk + China
1/10 its a fake .
jje
only buy from reputable store sources
never buy SD cards from ebay 99.99999999999999999999% they are fake
In the whole city of melbourne, there is nothing over 8gb class 2 card. What a sad place where i live...
Sent from my GT-I9000 using XDA App
I bought from ebay 16gb card,had a similar problem.all files above 1gb were non supported format. I bought a sd reader and connected it to a pc,using usb... same problem,I.e. card is defected.
Sent from my GT-I9000 using XDA App
I received a card today that was bought from eBay, i figured if i bought a brand named card(Kingston) that the chance of it being counterfeit was lower. I began to sync my samsung Vibrant with Double Twist and only about 20% of the songs were transferred.
I tried re-formatting the memory card in Windows 7 and the capacity is somehow reset to only 2GB...THIS IS THE SECOND TIME I've seen this happen. After that i try inserting the card into my phone and it' shows space unavailable... 2 PCs won't read it either.
Something this unreliable has to be fake. I recommend running a test with H2testw 1.4 to tell you if it's genuine or not.
Also, Kingston can actually verify your card for you. Maybe useful if you want to ask the sellers for info on the back of the sd card package first before buying! Good Luck
****KINGSTON MEMORY VERIFIER****
BTW- are 32gb cards just really unreliable should I go with 16GB ? I have a vibrant running ginger clone.
thanks for the link http://www.kingston.com/asia/verifyflash/
very handy for future purchases.... but it'll eventually be cracked by the counterfeiters people in time and generate fake "real" keys that passes the test

i think u own a fake card
Most of the memory cards bought from eBay are fake, unfortunately. I've came across a lot of victims as I work in a Kingston service centre.
I feel sorry for TS
Ebay = need to reasearch seller a little
I have bought quite a few memory cards and usb flash drives from ebay and I have never had an issue however, I do a little 'reasearch' before I click on buy.
I always look at ALL of the seller's negative and neutral feedback. This gives you a really good idea if they are selling legitimate ones. Also look at how much crap they sell, if they have only sold a few items sold I would go some where else.
I usually single out a few 'sellers' that sell a LOT of brand name memory cards. I also list items from the most expensive first to the cheapest, usually all the dodgy stuff ends up way back at the end. Being from australia I also filter it out so that i only see items that are goign to be shipped from Australia (double check feedback to see if theres any indication items are shipped from china/hong kong)
Just like kingston, I beleive sandisk also have something on their website to confirm if you bought a legitimate card.

Wonder how much it'll cost...probably not something I can afford right now, but hopefully the 32GB sandisk card I ordered during black friday gets out of backorder so I don't have to consider buying this now
just in time for the Nexus line to lose its microSD slot.
Never mind it was SD not micro.
hmm... ive been contemplating a larger card for my N1... looks like some more options are coming my way...
Patriot cards will now fail at record speed!
Best 32GB Micro SD Card for Nexus One
If you are looking for a good, high capacity, micro sd card for your Nexus One, you need to get the SanDisk 32GB microSDHC (cat. #B003WGJYCY). I bought mine in Amazon for $81.44, and right now is $104.95. Although is a class 2 card, I am getting speeds of 6MB for writing and 8MB for reading, with no lag at all when playing music, movies or using the picture gallery. I highly suggest that you keep your eyes open for this card, so you can buy it when it comes on sale.
I got in on a sale from sandisk where it was $56.99
Same card as the VZW TADP-32GBG?
http://www.verizonwireless.com/b2c/store/accessory?action=accessoryDetails&archetypeId=12214
I recommend the Kingston 16GB Class 10 is very fast, I use it without problems in my N1
although now I want the patriot
lexar has released a class 10 32gb
Good find!
I find myself upgrading my microSD too often. First, I had a 4gb class 4, then a 4gb class 6, then 8gb class 6, now a 16gb class 6 32gb class 10 sounds pretty juicy though!!

Droid 2 Global - Rooted - Stock ROM
Initially I found, even if plugged directly into my computer the transfer speeds were less than ideal, getting 5.5-8MB/s at best. If the SD was in the phone and I was transferring my 4MB worth of important data (rest could be transferred later) and the transfer would fail. Get i/o errors, further investigation showed that the mount to the computer was lost, but still appeared to be mounted on the phone.
I got my data on there by direct connecting the card to my computer using a USB adapter I had on hand.
When the card is in the phone it works fine for a while, until of course you try to access something on the card. Install an apk from there, access music, run Titatinum, whatever. The task misbehaves; the progress bar will be running and you can press home and do whatever, but if you let the screen go to sleep you cant get it to wake up. If you don't let the screen go to sleep the task seems to hang indefinitely.
I tried a few things, FAT32 used to have a partition limit of 32GB, and this card showed up as a 33GB filesystem. I tried shrinking the filesystem a bit (30GB) to see if that was the issue, but no luck there. I tried doing a format using the phone, maybe they had something they do there. No go.
My instincts told me not to go with Patriot, I should have listened to them. I am willing to try suggestions if anyone has to get this going, but in the meantime I am just going to stick with my 16c2 by Kingston.
Maybe I should have consulted compatibility first?

Email to Kingston said:
Dear Tech Support,
Product Number: SDC4/32GB-2ADP
Problem: This part has never worked. Well, a lot of users are having issue with Kingston 32GB microSDHC Class 4 cards as it seems its inferior, it took me 27min to transfer just 198MB. Where the same task is done on SanDisk 16GB Class 2 in under 2min. So why is Kingston producing piece of **** card and selling them for 100+? Alot of users in various forum can verify that this is piece of ****. This is bad batch so ill deal with Kingston for RMA directly.
Troublshooting done: Seems the speed is improved when the item is directly allocated in memory thus saving time from accessing it and transferring it. I am not sure if the device is using SD 2.0 but other people with SanDisk 32GB Class 2 is outrunning this Class 4 card. We are only getting like 700KB/s which is no where near class 4 standard.

Hopefully the plan don't backfire as I already placed order with NewEgg and still have to ship it back to Kingston. So in the end saved $60 or so and got class 10 card with 1gb extra space.

Telus HTC Desire - Rooted - LeeDroid 2.3d
When the screen sleeps, I can't always get it to wake up and am constantly restarting the phone. I was worried it was an issue with LeeDroid, and am currently troubleshooting my phone, but it sounds like once I re-insert my 8gb card I'll be fine. Thanks for the post. Amazed that they can build a card with limited compatibility as such but I suppose that's why it's cheaper. If I figure out otherwise, i'll post again.
Not compatible with Samsung Epic 4G
My wife and I purchased two of these for our Samsung Epic 4G phones, and unfortunately this card does not seem compatible with our phones. It will format and initially seem to read the card, however after a short while both phones gave a damaged SD card error and the cards needed to be reformatted. After the second reformat, we tried to give them another go, unfortunately files just continue to be corrupted. Very disappointed.

My moto x pure is on the way but Ive been searching out micro sd cards and this seems to be the best price/performance ratio I can find based on my limited understanding.
Can anyone state otherwise or have an alternative suggestion based on current market?

In my experience the biggest issue you will have is counterfeit cards I had 2 PNY cards of the 128 gb variety both supposedly fast cards neither were as fast as advertised they had decent read speeds but the write speeds were around 7MB/s or lower the Last sandisk card i had just quit working very abruptly. Since then i have stuck with G.Skill Sony and samsung cards the g.skill i have is very old and it is also slow the sony's i own preform adequately but the newer samsung cards i now swear by have really impressed me both reads and writes are blazing fast...
Im using this one, Read at 45 MB/s and Write at 18 MB/s. Its ok for me, dont know if will work good for you.

Lexar cards are pretty good just get them from a reputable company and be careful of Amazon as they are full of counterfeit cards.
I got this one for my X Pure. That said, I did get it at Best Buy last year on a sale for about $23 + tax. Pretty darn excellent performance except for the slow write speeds. Normally I wouldn't care about stuff like that but transferring a lot of videos into it can become a bit of a last question from Jeopardy, but completely stretched out.

got it
appears to be a legit card first and foremost uhs-1 u3 and 119gb useable.. Retail packaging ..Atto shows read and write just under 20 mb s with included adapter in my built in card reader.. no where near the 90 mb/60 mb potential but to be expected in standard usb card reader. ill see how it does with 4k video on the moto x

I should mention i tested the samsung cards in my phone and laptop and the write speeds were around 40 MB/s in both read was in the 85-90MB/s As far as my phone goes i did not see much change but when i move things to and from the phone it is a lot faster

I got the same Samsung card but from Amazon directly instead of a 3rd party seller, only paid $33 for it a few months ago, but I see the price has gone up since then. Hasn't made my phone explode as of yet :laugh::laugh::laugh:

I also have a 64gb PNY that I've had no issues with that I bought at a local box store, everything benched within (or close enough to) advertised parameters.

Got my moto and the app I found to test in phone shows around 40 mb write and 80 mb read... Not bad, Although this is the same or slower than your reported speeds for the samsung but was this the evo Plus? JJust asking for the benefit of others mostly it depends whats available for the $ AT THE TIME. It would be interesting though if the evo plus performed better than the sandisk UHS-1 u3 rated card

Mine was NOT the Evo Plus card.
Well, if anyone is looking at a decent deal on a 128gb card, B+H has this Samsung 128 GB card cheap: https://www.bhphotovideo.com/c/prod...g_mb_mc128da_am_128gb_evo_micosdxc_class.html
best buy has it on sale as well, but for $60: http://www.bestbuy.com/site/samsung...=4568502&productCategoryId=pcmcat351600050002
i just ordered one from B+H for my MXPE. (32gb/32gb just isn't cutting it)
UPDATE: the $40 at B&H was well worth...
You really must buy these things on Black Friday - Cyber Monday weekend. It is the cheapest time for flash memory and downloadable software ( antivirus upgrades, photo software, etc etc)
This card dropped to $ 99 , then $49. I grabbed for all of our Androids, and have 2 left over for other uses that may come up. Even if $49.99 is too expensive, they had the 64gb for $25.

..It is the uhs-I class 3 as photo shows.. not 10 as description says. Best Buy listings have several errors in wrong photo in correct listing, and vice versa.
( Btw... The Extreme Pro is now their UHS-II products.. Which you would get no use out of..And one test I saw said it could run slower in a uhs-I device..And those did not drop as much in price, if at all for the holiday sales.)
I'll chime in and say that it depends on if you're planning on doing adoptable storage (or 50/50 or 75/25 percent externalSD/adoptable space like I do), I have your answer right here.

You MUST go with the Samsung EVO+. This recommendation is valid as of mid-2016, that's when I bought mine, so perhaps something has come out since then that's faster.
But assuming not, which is probably the case, I did my research and the Evo+ is the only card on the market that can consistently hit the highest RANDOM r/w speeds. That's important because many cards will advertise their high R/W speeds but they are referring to the sequential speeds, aka writing a block of sequential data in a linear fashion to the card, aka image or video data. Adoptable storage means reading from many separate sectors of the card (where different apps' data is stored) and writing back to them, all at as high a speed as possible to maintain interactivity with your finger, which will always be bottlenecked compared to a predictable sequential write.
Trust me, I didn't think it mattered when I bought a 128GB PNY card for relatively cheap (not a fake one either, I didn't want to take chances so I bought legit off Amazon), set it up in adoptable storage and then balked as Facebook and Snapchat would hang for full seconds at a time, making the apps all but completely unusable. And this was a pretty highly-reviewed card, but then again most of the cards you'll find on the front page of an Amazon search are too. I did some googling and while I can't remember my sources, if you look around you'll find that the Evo+ is kind of in a league of its own, as it's the most recent iteration of Samsung's line and is essentially the fastest card available right now. I returned the PNY and splurged on a 64gb Evo+, dropping some storage space quantity in favor of quality. While apps aren't still quite as PERFECTly responsive as on the internal storage, it's a HELL of a lot better than with the other card, like an order of magnitude better, and in the 6+ months I've been using it I actually haven't noticed the infinitesimally small lag which makes it great in my book.
So, if you are only planning on using the card to take pictures and video, music, or other static data you'll probably be ok with any decent cheap card. But if you're even thinking of setting up adopted storage, or honestly even if you aren't, I'd recommend going with the most blazingly fast card you can get because otherwise you're just going to have a bad time. This is one of those things where cutting corners even a little bit brings down the whole house of cards.
