question about switching storage card

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

htc desire and 16GB SDHC from Sandisk

Hi!
a few weeks ago I bought myself a nice 16GB sd card on e-bay. The seller had 100% positive feedback on similar items, so I thought, this must be a nice guy. However, whenever I try to copy files to the desire after 2GB or so the transfer freezes and the file system of the card gets damaged, so I have to format it. Any suggestions as to how this could be explained/fixed? Otherwise I'm asking my money back (thank you paypal!)

i've a 16gb sandisk sdhc class 2 but never had such problems, maybe is something software related?

Ok heres the deal...
There is a chance the sandisk you purchased is not real, its fake, a 2GB reprogrammed to appear as 16GB. The packaging will appear perfectly real etc, due to the nature of memory carads returning them to sellers is near impossible as they will direct you to manufacturer.
The card might be damaged, have you tried a reformat, delete partition and recreate?
have you tested this in another machine?

+1 fake SD card. It's really hard to find legit SD cards on ebay

haha.
is there any reason why i shouldn't get the pny 16gb card from play.com? its £7 cheaper than the sandisk

It's your choice mate. I've had bad experiences with Sandisk cards in the past and only buy Kingston ones now.

i had the same issue with a 16gb kingston...package and all was 16gb, but it was a very slow 8gb...thrown it away.

Its seems more and more of the 16Gb cards from ebay are fake.
Have heard more and more reports of this recently.

I've had the same issue with large cards coming from eBay, so I'd decided not to be a cheapskate again and plumped for the best 16GB I could find.
Scan dot co dot uk
LN32905 - Kingston 16GB Class10
I also picked up an 8GB card for my Hero (Legendroid):
LN32725 - Transcent 8GB Class6
Haven't regretted it at all, however the price of the 16GB is a LOT.

Yeah i'd be looking to get a refund on that, sometimes the seller isn't at fault though, it could be that his/her supplier has a fake batch of cards. This is getting more and more frequent and a quick google search will show many horror stories as well as ways of checking to see if your card is actually a fake.
My advice would be to stay clear of ebay for memory and buy from a reputable distributor like play.com or mymemory.com
I purchased a sandisk 16GB ultra mobile (class4) from mymemory.com, think it was around the £45 mark at the time. Currently using around 9GB of it with no issues. Also transfers files much faster than the 4GB class2 that my desire was bundled with.

I am also having this kind of trouble with a Sandisk 16GB card.
The possibility that it is fake is very small for 3 reasons:
1. It works perfectly as a 16GB at my computer
2. It works perfectly as a 16GB at my camera
3. It was bought at the Sandisk master distributor here in Israel.
I tried to format it in the following way:
1. In recovery mode I partitioned the card.
2. I upgraded ext2 -> ext3 and then again ext3 -> ext4
3. took the card to the computer and formatted it FAT32.
4. copied the material from the old card to the new one.
And still, when I try to turn the Desire on with this card on it, it stays booting forever.
I am using REDUX Gingerbread rom.... is there something I am missing?
Thanks in advance,
Helio

use gparted / any partition manager to check whether you have duplicate ext partitions, it causes freeze, and make sure both fat and ext are "primary" drives and not "logical" drives

When you've copied the material from the old card to the new one... did you copied all partitions with a nandroid restore (and not just fat32 partition) ?

I just bought a 16GB card on ebay for £20 delivered, class 6. He specifically said it would meet the class 6 spec so I will Paypal him if it doesn't. I'll also test it in linux by dd'ing all the way to the 16GB to ensure it works.
Will report back.

Its seems more and more of the 16Gb cards from ebay are fake.

My £20 delivered turned up. It's a Lexar (apparently) and testing shows;
write speed: 8.4mb/s
reading: 8.1mb/s
So I'm not sure, read speed should be higher!

Second time got 7.9mb/s and 15.2mb/s. I think it's legit.

Same happens to me!

Yeah I've been stung with a knock off SD card as have two of my friends. I was 'lucky' mine was just poor quality so it had really bad read/write speeds and was able to send it back. My friends cards just didn't work and they couldn't get refunds.
The cards on eBay are cheap for a reason, pay the extra and get it from a reputable retailer is my advice.

You'll have to use microSDHC on the gTablet (or any device) if you want anything larger than 2GB
microSD (and the larger SD Cards) max out at 2 GB
microSDHC (SDHC in general) goes up to 64 GB I believe -- but only 32 GB cards are starting to be available...
I have a WINTEC 16GB rated at Class10 speeds that works fine. The price was right -- only $28 via NewEgg

Agreed Sandisk is a reputable company with a good product. I heard of to many issues with other "brands".

For any kind of computer memory I stick with the brands that I know and trust:
Kingston
Patriot
Sony
It's just too much of pain to lose your data and memory is ridiculously cheap these days.

I would throw in that the adata microsdhc cards you can get from Newegg are usually priced right and work great. I had one that went bad, but adata warranty replaced it very promptly. I have a few that I use with my Nintendo DS, which can be fussy, and they've always been great. Lifetime warranty too.

New External SD Card

I am wanting to go from my present 4 gig Ext. SD Card to a 16 gig one. I am looking at this one:
http://www.amazon.com/gp/product/B003WIRFD2/ref=ox_sc_sfl_title_4
Has anyone tired this one, it should be fine...Correct?
Thanks

I have a 32 gig kingston technologies sd card in my phone and it works as advertised. But beware.... I bought one from someone at my work that I did not know, same brand, looked identical to the kingston technologies technologies, markings and all. Worked for two days then never again. Called kingston, read them serial number and was advised that it was fake. You are buying from amazon so I would assume you wouldn't run into that.

which SD card to get?

ordered the sensation today and wanna ask first how is the card that comes with the device? are people using it or most of you bought a new one?
2nd, which card would you recommend?

It's not a bad card, 8gb class 4 so it's fast enough for most everything. What is too bad is that the phones doesn't have more built in memory. I can fill 8gb fast so for me, a 16 GB card is minimum and the higher the class the better imho.
There are a lot of cards out there, I would recommend a name brand unit and at least class 6. I've got a 32gb class 10 from newegg and it works great (cant find link right now).

good enough? or too much?

That's a link to the seller's feedback so I don't know what item you were looking at. Feedback seems good though.

A Data 32GB here.

You need a micro sd. That link is the wrong one.

ok i give up.. can anyone recommend me on a good and not expensive 16gb card?

I brought a 16gig pny card, its been very good so far.

Newegg has the ADATA 16GB Class 10 card for $25 right now. I bought it for $35 when I got my phone last month & I thought even that price was worth it

Try not to buy anything that are related to storage on ebay or online in general, e.g. microsd card, external harddrive, usb stick...they tend to be always fake. Best to go to local stores with good reputation for these things.

I bought a Lexar 32GB class 10 microSDHC card.
17 MB/sec read
8 MB/sec write
this was using SD tool for android.
I am hoping that once S-OFF is achieved, and we get cyanogen running on this device, the speeds will improve. The card cost me about $90 shipped, and came with a USB to microSDHC adapter. At this point I am very disapointed in the card's performance. Even when using my computer to transfer the data to it, the best I got was about 8 MB/sec write.
Also after a full format on Windows 7, the card only shows 29.8 GB capacity
though the detailed figure was 32,005,685,248 Bytes
I am hoping this card is not a fake. Can anyone else confirm their benchmarks with a 32 GB lexar class 10?

locate a Lexar 16gb class 6 from a reputable dealer.
can be had for around $20.
I get around 7-9mb write and around 17-20mb read speed.
seems like about the same speed as the class 10 Lexar above.
32gb version is too expensive still. don't understand why they cost almost 5 times more when the capacity is only double.

Your capacity is correct. The difference is due to the fact that a properly calculated byte, kilobyte, megabyte, gigabyte, or terabyte is calculated in base-2. The manufacturers have long been in the habit of calculating in base-10, hence the difference in what's claimed and what you actually see.

I think it might be a bit much to imply that any online vendor should be avoided when purchasing flash memory. As long as it's from a reputable vendor (not a ebay seller or amazon seller), you should be OK and in the event that you end up with a fake you would be protected by the vendor's return policy.

Like white i purchased a lexar 32gb class 10 card. Although transferring to the card was slower than claimed from my hard drive but transferring from my old micro sd to the new one i recieved much higher speeds with a class 6 limit due to the old card. As for onlkne vendors i have purchased all my external/internal and sd cards from ebay. I have had 1 problem but that was my fault because the offered price was too good to be true

hmm i read an article on the main xda page about microsd cards.. it says the sandisk one has better i/o and random reads and writes.. so now im really lost..well in the end.. u still cant transfer more than 4gb file onto your microsd card.

why cant you transfer more than 4gb file onto the card?

sorry for not being specific. You cant transfer more than a 4gb file because that's the limit for a fat32 microsd.... i believe.. lol

Yep, fat32 has a file size limit of 4Gb.

now i doubt there will be any difference between sd cards. We need a2sd or d2sd in order to evaluate better. On the HD2 there was a major difference between class 2 and a class 6 card. On the sensation i have tried class 2 and class 6 the performance seems the same.
