MicroSD 32GB, Transfer Problem - Desire General

hey Guys, i had two types of mark, a sandisk and kingston with both 32gb and both with the same problem.
What happens is this, I insert a microsd to miniSD adapter and put it in the laptop, transfer 4GB of music, it takes HOURS, when it ends, the files automatically erases, dissapear from sd card.
Anyone know please tell me why it happens?

Unfortunately that usually means the sd card is a fake, they are allover ebay. Basically they alter a 4gb card to make it show as 32gb.
I'd try and get a refund for the card if I was you!

TP2 and SDHC card problem

Since switching from a SanDisk 8Gb class 2 MicroSDHC to a Kingston 16Gb class 10 MicroSDHC (manfacturer part number SDC10/16GB-2ADP) I keep getting problems starting up apps that use the storage slot. For example, when I start CoPilot Live 8, it just freezes and I have to power off the phone, pull out the card, re-insert it and power on again (if I don't re-insert the card then a phone reset doesn't allow me to use the card right away).
Is the TP2 ok with this card, or is the card defective? I don't have problems using it with a USB MicroSDHC adapter.
I might save this card for use with a newer phone, perhaps a HTC Desire or Legend.
I don't know the Kingston, but my Sandisk 16 GB does not make any problems.
I have the SanDisk 16gb and have had no problems at all. Have you formatted your Kingston sd card? Maybe try formatting it on a different computer, or by putting it into a digital camera and using its format function? Hope that helps...

Yes, I've tried formatting the card. It made no difference.
I guess my question comes down to what class card the TP2 supports. I understand that the cards themselves are supposed to be downward compatible with devices that don't support the higher speeds, but some devices might struggle. I don't know what card class is supported by the TP2 (2,4,6 etc). I imagine any class 2 card would be fine, but what is the maximum class the TP2 should be able to support?
I don't believe it's the card because I'm experiencing the same problem. I initially started using the card in a nokia e71. bought the same reader as you: it just freezes and I have to power off the phone, pull out the card, re-insert it and power on again (if I don't re-insert the card then a phone reset doesn't allow me to use the card right away).
I'm using some noname 16gb card I got off eBay. Used it in my Incite and now in my Tilt 2 without issue.

XDA IIS Memory stick problems - 4 GB Micro SD with adapter

Hi all. I'm new on this forum and have recently had my new phone stolen from me. I decided to blow the dust off the XDA IIS and have spent the last few days on here fiddling with it.
I ordered a new 4gb memory card. It is 4GB Micro SD inside a SD adapter. and works perfectly in the PC. I also have an old mi nin SD 512 inside an SD adapter and this works. I 've spent hours reading the forum and can't find a solution. I apologise if this has allready been asked but does anyone have any suggestions?
Its an XDA IIS and I have tried numerous windows installations on the phone with the same result. It is now running WM 6.5.3
Thankyou in avdance...
as a matter of facts, it has been asked dozens of times already. but still:
4gb is the boarderline size for sd cards (sd, mini-sd, micro-sd doesn't matter).
4gb is available as an sd1.0 card (standard sd), and also as sd2.0 card (sdhc). the sdhc standard is not compatible with the blueangel.
or, in layman's terms:
every sd card of 2gb or less capacity works
every sd card of 8gb or more capacity doesn't work
for 4gb cards you have to look out, so you don't accidently buy an sdhc card, kingston and transcend have good standard 4gb cards.
Thanks for your reply. So basically it should work? I tried to make sure I didnt buy SDHC and it doesn't say it on the card. Would you say that the card more than likeley is SDHC?
what brand and model is it?
but afaik all micro sd cards of 4gb are sdhc, there are very few normal size 4 gb sd cards, namely kingston and transcend, but the majority of 4gb cards is sdhc and therefor incompatible.

[Q] help me solve this SD card issue please!

i have a 8GB kingston sd card in my tmous g2. i just bought a 16GB PNY sd card and im having troubles having it read by my computer(mac and pc) and my phone. heres what i did:
i copied all of my files from my sdcard to my computer via data cable so i could jut transfer them to my 16GB card. i put the 16 card in my card reader that came with it, into my computer and it wouldnt read it, so i tried the 8 in the same card reader of the PNY and it worked. then i tried to put the PNY card into my phone and it wouldnt recognize it. im not sure what to do.
why cant my phone or my computer read the card? its not the reader because my kingston card worked with it. is it because of the two different brands? any help would be appreciated. thanks in advance!

I had this same problem when upgrading the SD card in my HD7. I went out and got a Microcenter branded 32gig SD card and swapped it into my HD7. Worked flawlessly. A friend of mine got jealous because of the read/write performance increase, so he went out and bought the exact same thing. Only difference was that his kept locking up on him instead. He returned it and got the same exact size and brand card. After installing it, it worked just as good as mine. Turns out he just got a bad card the first time.
Sounds like the problem is in the card itself. If the PC won't even recognize it then there's probably something wrong with the card. Different brands shouldn't matter because the PNY card adapter worked fine with the Kingston 8gig card.
I'd return it if possible and get a different one.
I also just got a 16GB PNY card and I have had no problems with it reading data or having data be read off it.

Yep, I agree this is probably the issue. PNY cards are cheaply made and not great quality.

two microsd card died after deleting a file

Hi guys.
I've been using Qumo microSD card 16gb class 4 with un-rooted Galaxy S2 for a couple of weeks until some day the card just died.
I just deleted a file from card with totalcmd android app and it froze. After i rebooted the phone the card was no longer accessible. I also am not able to mount it in computer.
Thanks to warranty I've exchanged the card to the same one. But after working for just one week the same scenario happened.
I'm now going to try to exchange it for Kingston or Transcend card.
But I wonder maybe there is something wrong with the phone itself or maybe with totalcmd application?
Thanks, Oleg.
I think your microsd card is crappy. This happens with some sd cards. Stick with those standard reputable brands like kingston, sandisk, lexar, transcend and you shouldn't have any problems. Just to be safe, you should perhaps change to another file explored. OI file manager is small in file size and fast.
u shld ave ckd the card , connecting it to pc by a card reader..

Usb storage damaged message

I keep getting a usb storage damaged message. I have read that it is sometime an issue with the galaxy s3. Also sometimes when I first unlock the phone it says prepping sd card even though I did not remove it.
Also my SD card is a SanDisk 64gb class 10. I have read that this can be an issue with a certain crop of SanDisk.
Any tips? As of right now entitling works and if it's just messages popping up.

Have you tried using the SD card in other devices and on a computer?
I had a *similar* problem with an old MicroSD card in my original Galaxy phone and formatting the card seemed to work. I can't speak too much to your issue because the largest MicroSD card I've used is 32 and it's been flawless.
Yeah, verify across devices first. If not, try filing a claim with SanDisk if you purchased the sdcard only recently and it's already gone bye-bye.
