Mini sd 4gb

Hello, I've seen on Ebay a minisd of 4gb.
Is it compatible with Treo 750v? Anyone has tried it?

Hey,
Ive tried one in the XDA mini S it works in mine, but doenst work in my dads? think its something to do witht he contact length on the actual mini sd card, the longer the better. BUY A WELL KNOWN BRAND!

Actually I believe it has to do with the either the operating system's or hardware's ability to address 32bit file allocation tables. 16bit FATs only address (under normal circumstances) 2GB volumes. I believe official SD specifications require any hardware requiring more than 2GB to be SDHC (SD High Capacity) wich addresses volumes differently than none SDHC hardware/cards.
So in short, without having first hand experience to try it, I do not believe 4GB cards will work on the Treo. I'm sure, however, that someone will quickly come along and correct me if I'm wrong ;-)

I found this thread http://forum.xda-developers.com/showthread.php?t=289848&highlight=sdhc and then found one on eBay from the link on that page. I won my bid and just paid for it. I should receive it within two weeks, at which time I will try to get back on here and let everyone know if it works for me.
My phone is actually a (UT Starcom) Audiovox PPC 6700 from Sprint, but I would guess that there isn't much difference pertaining to the miniSD driver and what it can/can't read. Also, I can't see WM5 having trouble with the FAT32 file system, but I could be wrong. You *can* format FAT16 up to 4GB, but it is HIGHLY inefficient compared to FAT32 at the same size.
I just hope MS releases a driver for SDHC support soon. After all, miniSD still uses the SD driver. The only difference is physical dimensions, hence why you can put a miniSD card into the SD adapter and it works in SD card readers. The pin-out is the same, etc.
Here's hoping all works well for me. I want to be able to ditch my iPod and only carry my phone.

I have not formatted a memory card with FAT 32. I do not know how WM5 will handle FAT 32 but I know that SDHC has more to do with addressing memory than simply FAT structure. There are hardware differences between SDHC and non-SDHC.
The physical similarities between the SD cards will not make up for the fact that they are internally different. Just like a CD will play in a DVD player but not vice versa. An SD card will work in an SDHC slot but not vice versa.
4GB SD cards do exist but do not fall within legitimate*SD card standards. They may or may not work based on the card manufacturer, the host device, and the direction of the wind. Keep your fingers crossed and your receipts handy.

main question open again
So coming back to the main question,
has anyone tried the 4GB miniSD card (they are all HC, FAT32 formatted) on Treo 750?
I am waiting to decide whether to buy a 2GB or go for the 4GB and come to the same capacity level as the iPhone (4GB version!).
thanks

4GB miniSD cards and the Treo 750
I've got a 750v -- had it for several months. I was using a Transcend 2GB 80x miniSD card that worked just great. No issues with "disappearing", pretty fast read/write, etc.
I wanted a 4GB card so decided I would try a SDHC card from Transcend. It does not work in the Treo 750v. Works fine in my newest PC card reader, but no-go on the Treo. Figured as much, but wanted to try.
Then I bought another 4GB card (non-HC) from eBay that was branded Topram. It suffered the issue of not being able to see the card on the Treo without doing a soft-reset first, and it was very slow in writing to it -- like 1-2MB/sec from a USB 2.0 card reader. Didn't much care for that.
Just recently bought yet another 4GB card (again non-HC) from eBay. It was a generic card. I'm getting 3MB/sec write speed from my PC card reader, which is slower than my original 2GB Transcend 80x card, but not as bad as the Topram card. On the Treo itself, it's read speed is about the same as with the 80x Transcend 2GB card, which was pretty good. Overall the Treo feels about the same with the 4GB card versus the 2GB card installed, in terms of launching Tomtom or playing MP3s.
It also does not suffer any "disappearing" or the need to soft-reset the Treo to recognize the card. I've ejected it many times and put it back it, and have never had any issues with this. I'm going to stick with this card for now, as it seems fast enough and isn't causing me any grief.
This card is shown here: http://cgi.ebay.com/4GB-MINI-SD-SEC...QtcZphotoQQcmdZViewItem?hash=item110080023472
So, that's my (long winded) story on 4GB miniSD cards and the Treo 750v.

I just bought a 4GB mini SD from MobyMemory.com for my O2 XDA mini S. The first card would not register at all with the device. I sent it back and the replacement now at least registers (as 4GB) but after loading any sort of volume of data on the card/device it locks the PPC up!
What BRAND of 4GB mini SD card did you get working with your "XDA mini S" (and did you have any problems once you'd actually started using it to store anything over a few MB)?

Tresend 4gb mini-SD card doesn't work with Treo 750...

stay away from ebay when buying memory(card, flash drive, etc...)
90% of them are fake. Although they might work just fine, chances are it'll crap out on u eventually.

WISH I WOULD OF FOUND THIS SITE EARLIER.
Yeah I just bought a transcend 4 GIG mini-sd for my TREO 750. IT makes the noise as the TREO recognizes it but it doesn't show up in file manager. I have formatted it with my USB SDHC card reader, I can only select FAT32, and it shows 3.75 GIG.
NO GO ON TREO 750 (CINGULAR)
-anyone have any ideas on how to get it to work?

Storage card became unaccessible

for the 2nd time I can not open the files inside the card. They are not even shown in the screen. But they are there as when I go to memory, 1 GB is used.

same problem, haven't been able to figure it out. I'm defecting to a blackberry, this is too much of a hassle

Which cards are you using ? Brand, size, format etc
Having asked that, I'm on Sandisk 16Gb SDHC for about 4 weeks now, having evolved from the Sandisk 8Gb variety.
Up till today, I would have sworn by Sandisk - no hassles at all for over two years.
Then today the 16Gb card corrupted. To be fair, there were warning signs for a few days previous (programs not loading correctly, the device hesitating on save, and so on), but I didn't diagnose a corrupting card as the issue as I've had no problems with them for so long.
Recovered now, re-formatted the offending card (FAT32).
My view at this stage is that it was caused by a program Card Studio. This seemed a brilliant diagnostic at the time, as it announced it found rogue clusters on scan and repaired the card. Small footrpint, quite fast scanning.
But soon after replacing the card with a new, unused one, Card Studio announced in fractured English that the 2 FAT copies on the new card didn't match. So I re-scanned with Pocket Mechanic as a check before letting Card Studio "repair" it.
Repeated scans with PM found no problems and the card is working perfectly.
I suppose one may draw certain preliminary conclusions here.

It's a sandisk 4gb sdhc

[HEADS UP]SanDisk Ultra 16gb MicroSD Class 10

Just thought I should let you all know about my recent experience with this microSD card.
The Part number is SDSDQY-016G-A11 or SDSDQY-016G-A11A
I bought one from my local Best Buy after finding the item was marked down from $49.99 to $17.99. At first, my initial thought was "Done!" I took it home, opened the package and began transferring everything from my 8gb card to this new 16gb class 10 card.
Now, here is where the problem starts. I do not know if I did not take the necessary prerequisites for this particular card, but, after about an hour of just basic copying of data to the new card, I was struck with a CRC error and the card forced ejected itself from the USB host. I removed the card and put it back in to see what happened and found a corrupted directory from the last thing the card was copying. I couldn't access it or delete it. I couldn't copy anything into the card either. I tried formatting, to which it would complete the operation with a "This card could not be formatted." message at the end. I tried downloading different partitioning software to delete the partition, format the unallocated space and create a new partition to which I was "then" greeted with a variety of "This card is locked/Failed Operation/Space cannot be formatted/Partition could not be created." I gave up. I went back to Best Buy and exchanged the card for a new one. I thought "F*** me right? I got lucky with a bad card."
Nope.
Same thing with the new card, except it happened within 5 minutes of copying anything onto the card. This time around, I decided that I am not going through all of that again and returned the card.
Again, I do not know if I took all the necessary prerequisites before handling the card, but, to my knowledge I do not think there could be anything.
Instead, I jumped over to Hhgregg and found a different model SanDisk 16gb microSD card. I was able to copying over everything over to that card the first time and without a problem.
Also, in case it's asked, the phone did pick up the card initially before anything was copied. After the problem's arose, the phone refused to mount the card at all.
So, if anyone was considering picking up this card, its up to you what you want to do. Just Beware.

I found that the SanDisk USB device/ other SanDisk Adapters was causing errors in the 15 or so misc cards I put through it. Were you using it? or was it in your phone?
I went with the 64GB SDXC and no issues since.

At first I used the supplied adapter which is when the first card gave out. The second card I used a different adapter. A USB based one and it still gave out but much faster. Initially I tried with the card in the phone, but it kept force ejecting itself from the USB host as soon as I started. I thought it was the cable at fault.

I have the same problem i purchased 16gb ultra yesterday and today i m unable to format this card in NTFS system it formatted succesfully in fat32 bt the speed i get white transferring any file is jus 3.5-4 mbps olease help any solution for that??

I have a 7 months old SanDisk ultra 32gb and it's still very good. I have better speeds when copy inside the recovery than inside the rom.

Did you report it to Best Buy?

MicroSD card

I just bought a new 64GB PNY Pro Elite microSDXC for this tablet, and every time I try to move a file, an app, or anything to the card, I'm given an error. It says unable to move. Not enough storage space. I read somewhere else that people had trouble with the 64GB cards, but the 32GB cards worked fine. Has anyone had issues with the 64GB MicroSD card?

Odd, I've never seen that issue on mine, not on the 64GB nor on the 128GB(which is my regular card).
Mind you, I only use Sandisk, and never a lower-tier brand. Too many problems when you use anything other than Sandisk or Samsung cards.

If you have an sd-card reader/writer for pc, googling you can find several utilities to thoroughly test your card.
If the card is OK and you are rooted you can try sdfix, a free utility that fixed random write access problems to the sd-card on my tablet after the upgrade to lollipop

Well, I found a few other people who had the same issue, and they used a command line app on their PC called fat32format, which formats devices above 32GB. They said it fixed their problem, but I didn't think MicroSD cards on an Android device were formatted FAT32.
Either way, as ShadowLea said, I normally use Samsung and/or SanDisk cards and have never had a problem taking it out of the box and plugging it in. I ordered this card because the description read 95MB/s read time, but if I'm not mistaken, Samsung and SanDisk both have cards like this. Since I just received it and have 30 days to exchange it, I think I'm going to send it back. I shouldn't have to use any app to get it working correctly right out of the box. I guess this is what I get from deviating from the norm.

Galaxy S7 has corrupted my SD card

I have had my S7 since pretty much the beginning, I was fortunate enough to receive mine fairly early compared to others. Along with purchasing my new phone, I got a Samsung 64GB EVO Class 10 SD card to take advantage of the expandable storage. Everything had been going find until earlier today. I noticed that I got a notification that my SD card was corrupt, I didn't think it was that big of a deal as I didn't have very much data on the card as of yet so I clicked the option to format it. The phone seemed to be having issues reading the actual card as it couldn't seem to format it, an error kept popping up saying that the command had failed. I then put the SD card into my laptop to see if I'd have any more luck with it, and sure enough windows told me that the only way the card could be read was if it was formatted. After formatting the card through my computer, I put it back into my phone. It worked for about 5 minutes or so before telling me it was corrupt again, I'm not exactly sure where to go from here.

I had this Samsung 64GB EVO Class 10 Micro SDXC Memory Card with Adapter (MB-MP64DA/AM) from amazon with my S4 with no problems since it went on sale back in December. Last Friday I got the same message that it was now corrupt and I need to format it. My computer cant see it and I have some intense data recovery software that cant help either. Since those little SD cards have a 10 year warranty I got on the phone to Samsung. I spoke with a Samsung Galaxy expert and they advised me to call their Micro SD support team at 1-800-726-7864. I'll call them tomorrow and report back what they say.

Prolly got a fake from amazon

Amazon do insist they don't sell fake cards, however I have had the exact same problem with the exact same memory card, also bought off amazon. I've used this card in a few different phones with no issue, however upon installing it in my GS7, within a few days I got the same error message as described here. I have contacted Amazon and have had a replacement card (same one) and will see how it goes. I'm on about day three so far with no apparent issues. Tick Tock Tick Tock.....

I'll probably call them up also.. but I think I'll see what happens with yours before I just destroy another SD card

Just got off the phone with Samsung. They're sending me a RMA form to fill out through my email for a replacement. After the whole amazon fake SD card fiasco they're going through they are being very helpful so far. If you can return to amazon it will probably be quicker but I am at day 100 or so with this card.

I think I have the same problem. I have a Samsung card also (not evo) and have used it in several phones without a problem until now. In my case the card corrupts at reboot. I managed to f around and somehow the card was readable again (after re-inserting several times). However on the latest reboot I the phone no longer detects the card at all.
I doubt I have a fake card as I have been using it for over a year now and almost filled the capacity (64GB). I even formatted it when I first inserted into the GS7.
I have since ordered a new card but I hope this phone is not going to be killing cards!

RMA received. Samsung wanted a jpg or pdf of sales receipt and a pic of the back of the card. Card will be mailed to Samsung at my expense ($2 ish) and a new unit will be sent out. Fingers are crossed that the fast charge tech isn't sending card killing voltage spikes through the phone.

Just a quick update guys, in case it helps anyone, but my new card replaced from Amazon is working OK so far without issue.

Update, whilst it hasn't killed my SD card, I've just had an update and after that it refuses to write to any memory card I have. So I'm returning it tomorrow, it will read OK, but not write to.

I'm using a samsung pro+ 64GB card with my S7 and that annoying SD card notification keeps popping out. Sometimes I could see another notification said SD card removed/unmounted unexpectedly then the annoying notification. I've tried using an old 32GB TF card and I've never seen this annoying notification.
My guess is that S7/S7E have some compatibility issue with even Samsung's own newer and faster SD cards.
I'm waiting anxiously for an OTA hoping this is a software issue. I hope my S7 won't corrupt my SD card.

Update: Just received my replacement micro XD from Samsung in less than 2 weeks, very cool. I like their new usb card reader, very slick. Well see how long this lasts. I also just had a OTA update to the S7. Lets see what they fixed.

Same issue
Exactly same scenario as bensto23 first described, same SD card, however....I replaced that 64GB Samsung EVO with a Patriot 128GB and after about 2 weeks the same message popped up. But when I put this card in my laptop it couldn't see a problem (the Samsung was unreadable). So the Patriot went back in and everything was good until about a week later....same thing. S7 says the card is corrupted but it's not and works fine after removing and replacing. Haven't had time to call Samsung support but obviously this looks like an ongoing issue. So frustrating since this phone has been so flawless otherwise.

My S7 is in for repair as I type this. It's 6 weeks old. I had a 64GB SD card that I had used in my S5 for 18 months with no issues. I didn't have an S6 due to lack of SD slot and not waterproof. At 3 weeks old, the 64GB card developed a problem. I removed it from my S7, put it in my laptop, only to find it was corrupted, and I couldn't do anything with it. I put it down to being one of those things, and bought a 128GB SD. 3 weeks in again, and exactly the same fault! It is a hardware issue with the S7. I put my 32GB SD card in from my LG Leon, and the S7 wouldn't read that either. Be interesting to see what Samsung will do about replacing cards that have been destroyed by a phone!

Think i might be facing the same problem. When i put in a Sd card my phone freezes up a couple of times a day and without a sd card it running fine. I even think it messed up my first sd card because even after a format i cant write files bigger then 1 gb onto the card without getting a error on the computer. Also i can only do a quick format and if i do a full/long one it will eject the drive and fails every time. Im to scared to try a new sd card and think ill send this one back for warranty.

corrupt sd card
i have same problem with A7(2016) but i use 64GB U3 kodak SD card. it works fine until last week. i saw that i cant play musics so open memory by ES file Explorer and it says that empty. but when connect it to my loptop it had no problem and i find some files that recently created and remove files with 0 byte size. then connect memory to my phone it works nice but some day later the sd corrupts again and i repeat every thing i do last time and it work but sometime later corrupt again. i am confused how i can stop this cycle
help if can please
sorry my english language is not good

Every phone I've had, every forum for that phone, complains of issues with Samsung cards, I would never touch Samsung cards. I've never had an SD card corrupt or fail but then i've never bought a Samsung card.

Got the same problem. Every time I reboot or unmount the external sd-card, the card becomes "corrupted". When I put the card in my PC it's just fine. I can read and write to the card.
I've got the 128gb sd card from Samsung (got it for free with the purchase of the phone).
Getting sick and tired of having manually backup and restore to my SD-card when I reboot my phone. Does anyone has a solution for this?
**EDIT
This must be software related, since when I do not reboot, the SD-card works perfectly fine. It only happens when I reboot or unmount.

had the same problem in my s7, it turned out for me the culprit is when I enable the pics saving to extsd option in camera. this corrupts my extsd.
before extsd it worked perfectly fine for days and weeks and survived plenty of reboots in the S7 (and in my previous phones as well), but as soon as I enabled the pics saving from camera to extsd option in the s7, at next reboot the message about corrupted camera came out. I can replicate this problem with these exact steps, so it is 100% sw issue for me, and related to that option in camera settings... if I use my intsd for camera pics, everything works just fine, I can see and access all my other content in the extsd etc.......
