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] Installing a new SD card

I have just ordered a 16GB SD card to replace the 8GB one I have.
Do I need to format the new card in the phone before transferring the old data?

You have to format it somewhere to be sure you have correct cluster size.
Try card after that with free SD tools (http://veluscek.amebis.si/index.asp?selektiran=sdtools). There is free market link.
Regards, Ales

I am also purchasing a 16Gb SD card . I was going to format it using the phone. You can unmount the sd card and then format it. Is this not a good idea?
I was also going to copy the contents of my current card to my pc, and then copy it back to my new SD card. I am assuming this is the correct way of doing things.

I just changed to a 16GB Class 2 about 2 weeks ago. I just copied everything from the 8GB to my computer. Put the 16 in, and copied everything from the computer to the 16. Everything is working fine. No formating. I did check the phone before copying to it (16), and the format option was not selectable. It was grayed out, so I just copied.

would upgrading the stock 8gig sd card to a class 6 make any difference?

You'd probably only really notice a big difference when copying files from the PC to the phone. Don't think you'd see much of an improvement when opening anything on the phone.

If I'm not mistaken, mine is already upgraded (so-called) to class 10 from my previous phone. I however do not notice any difference in performance.
I think suddy86 is right. Even if there is, I guess it would be hardly noticed.

I have purchased a class 6 card. It was only a couple of quid more than a class 4. Its a Kingston SD Card, so should be good. Didnt fancy buying an unbranded cheaper card.

Another question that I am curious about. Can a nandroid backup made on a 8GB sd card, be restored on a 16GB card?

i believe you can just copy the contents of the 8gig to the 16gig (unless its a gold card)

SD Card

Hi
I have a problem with my htc and i need some help if you can. I recently got a 4gb sd card for my phone and it doest work on it but the card works perfectly on the Samsung Galaxy Mini and the HTC TYTN II that i also have .
So my quastion is this. Is there anything else to do besides the format or the phone supports a special brand of a 4gb sd card??
P.S. please post me a link of a giude on how to upgrade the phone i ve been reading the wildfire section all day today and the only thing i found is the rom section.
Thanks in advance

Your phone could have a faulty card slot. If it's still under warranty, return it and get another one.
As for your other question, here's a link to a list of guides to help you through whatever you need: [INDEX].

Thanks for replying and trying to help.
I am really sorry but i forgot to mention that the 2 gb card that came with it or the 1 gb card from the Samsung one works perfectly on the HTC so the card slot is no issue i also took the phone to the company i purchased it and they said that i have to leave it there to check it but they will charge me because i installed the 4gb card my self
Thanks again for all the help you can provide

What's the brand and class of your 4GB Micro SD Card?
I had problems with a Kingston 8GB class 10 Micro SD Card, it was recognized by the phone but it randomly unmounted the card.
When I bought a Samsung 8GB class 6 Micro SD Card the problems were gone.

The brand of the card is kingston transcend 4gb.
That was my first estimation that the brand might not be compatible but i was hoping that it might be a soft upgrade or an application that could do the job and mount the card because mine it doesnt mount at all.
I will try and replace the card with another brand and see if it works
Thanks for all the help guys.

Sd Card?

Which 32 gb 10 class for ZL? Samsung , sandisk , sony, transcend or which? Need to buy one soon.

samsung or sandisk both are good. Just so you know the 64gb sandisk works in our ZL's

i know 64 gb works but it's too costly for me so i am going with 32gb.

juct check my sig, im using 32GB UHS1 from sandisk and work well.

Me too. Iam abt to buy a card. But im scared that the card might get corrupted. Is dat corruption problem common in ZL too?? or only in Z?
So iam thinking of buying a Sony micro sd presuming it will not get get toasted!
So tell me a brand less prone to corruption
Thanks

When I got the phone, I just reformatted it using the phone. I never even looked in to what extension it's using. This was on 4.1.2, and it read it as 64GB then, though I believe the new update says it NOW allows 64GB. I just copied the card onto my computer, reformatted the card, and then put everything back on it. No problems up to this point, though I've only been using 4.2.2 for a few days.

I just picked up a 32gb Sandisk Ultra UHS-1 for it. (64gb was pretty spendy and far more than I really needed) I hope this was a good choice on my part, but judging by the comments it should be fine. I should have my Xperia ZL on Wednesday and will report back how it works out. (Just ordered it, got free overnight shipping)

I am using SanDisk 32 GB UHS-1. Just reformatted it with phone to see, what file system is used with new firmware. It is formatted in FAT32 by default. No problems so far.
Sent from my C6503 using xda premium

So I finally brought a 32GB SanDisk ultra uhs 1 class 10 today. I just hope it doesnt fry
Also, is there any option to format the card on the phone?? if not then do I need to format the card on pc? Which format should I use? ExFaT or FAT 32?
Thanks for ur help..

It Works!!
Bought Sandisk 32GB 10 class 1-2weeks ago and it's working without any problem. :good:

Whatever you do, be wary of corrupt/mislabeled SD cards!
When you get your SD Card, always first check it out with a tool like H2testw or Check Flash and make sure that the reported size (32GB, 64GB) is indeed the actual storage capacity.
I once bought a 16GB flash drive that could only store 8GB of data; exceeding this 8GB would corrupt the data on the drive. H2testw proved that cheap deals online usually come with a price...

[Q] Micro SD Card problem

Hi there.
I'm having problems with the SD card, is always unmounting with no apparent reason...
When I'm on the Album (or gallery) and I scroll trough the photos (I've got a few) the card is unmounted and I need to take it of, and put it back in...
While I'm copying files from the PC to the card (trough the phone) the same thing happens...
The card is a sandisk class 10 32Gb... it was used on my SGS2 and never had any problem...
Does it worth to buy another card, or someone else is having the same problems?

I think this is a problem with your sd card. I don't have any problem like that.

Can you please tell me what card do you have?
I have already formatted the card on the pc and on the phone, the result is the same...

Weird problem, I own a Goodram 32 GB Class 10 micro sd card and I haven't got any problems with it. You say that you have tried formatting the card. What format have you chosen? Have you tried reset to factory reset your device? Are you on some custom rom or the stock one? Do you have a possibility to check wheter the problem exists with other micro sd card? Perhaps you can borrow it from someone for a moment or you have another one somewhere. Worst case scenario the card port could be damaged.

I have a Kingston microSDHC 32GB, Class 4 :good:

Hi,
I'm sure that's an issue with your sd card. I've had the same issue with my old SGS3 and an SanDisk 64GB sd card. Then I bought a new Kingston 64GB sd card and it works.

I formated in FAT and in FAT32, same result in both.
Im in the stock ROM, totally unchanged.
I already get a new card and I'm testing it now, if it stills get me troubles I will try the factory reset.
Yeah... that is my fear... that the port is defective or something like that

Ok, updating from the previous post.
I've bought another SD Card and although that on the first time that I used it on the phone, it gave me the same behavior, after formatted it on the phone itself, so far so good.
I've tried the old SD Card with an adapter on the pc, and it works fine, no problem at all... so it must be something specific to the phone, I've read that some Samsung are a SD card eaters, so I believe that the problem is related to that (my previous phone was a SGS2).
Thank you all for the tips.

Not necessarily.
Card of class 4 may be good enough for your computer, specially if it is older too, but may be too weak for newest modern phone.

An SD card can't be 'too weak'
