Micro SD card sometimes disappearing

I am using T-mobile Touch Pro 2.
I am quite satisfied with this device except for one problem.
Sometimes (once a day or every other day?) when I turn the device on, the micro sd card is not detectable. The card is in the slot, but the device just cannot find it. (It shows like there is no sd card!)
When I reboot the device or take the micro sd card off and insert again, the device recognize it which makes me very annoyed.
Anyone who has the same problem and the solution?
Many thanks in advance.
FYI, I am using Transcend 8GB micro sd card (class 6.)

The only time I have something like this issue is when I connect the phone to the PC as an external drive, which is by design. Unplugging the phone sets it right again.

Change your MicroSD to SanDisk and you wont have any problems. I have a class 2 16GB and I dont have any problems. If you're worry about the performance, it's pretty fast. using the phone as removable drive it writes at just under 4mb/s, using a usb adapter and the write speed sustains at 8-10mb/s which out performs minimum class 6 standard. All the test was done on a 16gb class 2 with 10gb of badly fragmented files already on the card and writing another 5.5GB into the card. I havent tested read speed but it's faster than write speed.

I had the same problem when i first got my sprint pro 2. All you have to do to fix is... using any card reader, copy all the files on your micro sd card to a new folder on your computer. then format the card to fat32. once formatted copy all of your files back onto the card. pop it back in and you should be good to go.. after doing this to mine, my 16g card hasn't disappeared once.

[Q] XP won't read app data in new micro SD card. Help?

Hi everyone,
I read that the process of upgrading to a new micro SD only involved a simple copy and paste from the old card. I got a SanDisk Ultra 32 GB MicroSDHC (SDSDQUA-032G-U46A) and after multiple tries I cannot get my Xperia Play to properly read the data from the old card once it's on the new card. I've tried formatting the card with the phone, with the computer, and nothing improves (I used FAT32 as the format). The closest I got was the app icons showing up properly but the apps force closing once I started them.
What can I do? Is there a tool that will allow me to transfer everything without screwing up path files in the process?

Anyone?

check the sd card if its fulty(yes there is sd cards that fulty from the shop).
the best way to do it is put the sd card to adapter (sd card to usb) and connect it to the pc.if its not working.take it to the shop you buyed and replace it.

Is the sdcard legit? Did you buy your sdcard from reliable source more info would be nice. Is your sdcard formatted to FAT 32?

Same issue here
Formatted on computer to FAT32. Copied files over via computer, stick the new card in. Phone lags and freezes, apps are "not installed", and when I try to format via the Play, the phone just freezes.
Card is legit, bought from Best Buy, passed all the tests, works just fine using a an adapter (usb and regular sd).

Google for: "MiniTool Partition Wizard Home Edition Setup" It's freeware. Put card into a reader, not phone-to-pc, start minitool, and look, if there are more than one partition and if it is FAT32!
Hope that will help!

You can also try the hp format tool from here http://files.extremeoverclocking.com/file.php?f=197
It is much better than stock windows formatter.

Tried,,,but nothing...say that the sd is read only and dont give me any options.Thanx

How many files/folders do you have on the card?
Maybe too many AND very small size?
If not, then check a pc with linux and try to format with it...

D855AR not recognize micro sd 128GB

Hi guys,
I have problems with my new Samsung 128GB EVO Micro SDXC. The phone recognize it and let me save photos, music and any data. But any time i reboot the phone it not recognize the micro sd and i have to format it so the phone recognize it again.
I try to format the card in NTFS file system and ExFAT in 32kb and 64 kb, also make a hard reset of the phone. Nothing works, still have the same problem. I put the sd into another phone and works perfect.
It can be that this model of micro SD is not compatible whith mi phone? The exact model of my phone is D855AR.
Any idea?
Thanks in advice :good:

micro sd card problem

I'm having a problem with this brand new 32GB kingston canvas select micro sd card. Bought it for my dad, he's using a 100% stock G5. When first plugged in, the phone asked if the card was going to be used for internal or external storage, chose internal because my dad is kind of an app maniac (yeah, I know, tried to get him to stop but he's stubborn), formatting stopped at 30% for 10 minutes. Rebooted the phone, it stopped recognizing the sd card. Tried it on my phone, which is also using a 32GB kingston sd, and it didn't recognize it either, on the PC it works fine. Tried formatting it to every file system known to man and none of the phones will even know there's an sd card plugged in when using that particular sd card, but both will work fine with other cards. Could someone give me a hand with this?

I would use minitool (windows) or gparted (Linux)
Delete all partitions on sdcard
Create a new fat32 primary partition and format it

Other than factory resetting the phone or trying a different sd card there's nothing else you can do
