Micro SD card not detected

So today i brought a 8gb Transcend Class 6 mico sd card for my raphael. So i went back home and try it then i found it not detected on the file explorer but it says expansion slot in use when i go to Settings>About. Thanks in advance.
[email protected]

Transcend is not recomended by HTC. i am also having same problem with my SD card which is made by Transcend (4GB capacity). it detects when you put it in phone for a longer time, but you can not write/save/copy anything in it. it will say FILE CAN NOT COPY, MAKE SURE THE PHONE IS PROPERLY CONENCTED AND SOURCE FILE IS NOT MOVED BLA....BLA... BLA...
when i checked with HTC team, they advised me to use micro SD from SANDISK.

well the weird thing is when i insert the card on my friends phone(HTC TYTN 2) it detects it instantly after inserting it in. But when i insert it on my phone it doesn't work, btw i also tried another card from my friend, it a sandisk 4gb and it worked. hmm this seems top be a uncommon issue.

I ahve the SAME exact problem with the 8GB Transcend Class 6 Micro SD that I just bought for my phone. I've had no issues at all with the 4GB Transcend Class 6 card that I currently have. On the other hand, I had a 4GB Sandish Class 6 that would not work in my Raphael but would work just fine in my Kaiser.

Appearently the card worked randomly but i can't copy any file to the card for some reason.

look for something called SDformatter by panasonic i had similar troubles with a couple sd cards till i found this program.
they all work now in any phone/device.

Is there any specific setting to set in the program Panasonic formating program? Erase enable or whatever? I had my SD card working for about 2 or 3 days and now its not detected again.

I have similar my 8GB does not get recognized and if does it's only for a matter of minutes then corrupts but my 2GB reads fine, but the 8GB is fine in Kaiser already used the SDformatter to which makes it read till corrupts again within minutes...
Going to try some other cards out in local shop before purchase will take laptop to transfer data while there.

I have read in a lot of post that Transcend 8GB class 6 card have problems to be recognized by Rapahel.
I also have one. On my Kaiser worked well.
With stock rom it wasn't recognized by Raphael; with Energyrom it is recognized, but i used for few minutes, because i feared that something bad could happen..after reading all these post.
I usually use a Kingston 2gb card.
We were unlucky buying these cards...

Yes, I also have a Samsung 8GB class 6 card that my Touch Pro refuses to read. Tried an EnergyROM as I had read that for some reason they were better at reading some cards. But no dice - just bought Sandisk Class 2 and it works perfectly so far

Transcend 16GB SDHC Class 10 card

Bought a Kingston 16GB SDHC Class 10 card for my Desire a while ago, and found out it is not a happy match. Simply too unreliable. Went back to the good ol' trusted Transcend 8GB SDHC Class 6 card.
Anyone got any experience with the Transcend 16GB SDHC Class 10 card on the Desire?

Hi,
I have a Kignston µSDHC 16Go class 10 and I'm very happy with it. What do you mean with "unreliable ?"

My device was becoming noticably slower with this card instead of faster, and I got read errors continuously in apps like media players, Astro File Explorer en Root Explorer. Possibly it was becoming slower because of the read errors.
A chkdisk on Windows 7 continuously gave errors and a chkdsk on EXT4 Recovery sometimes was even unable to fix errors on it.
Reformatting only helped for a short while, then the read errors would reoccur.
So I finally gave up on it and trashed it.
I read everywhere that the Desire is very picky when it comes to memory cards.

Well, it seems like your kingston card was dead, it shouldn't give any error on a chkdsk.
Did you know you can get it exchanged from Kingston under warranty ? It has a lifetime warranty. I had to do it for mine because the first one I had was defective from the beginning, I couldn't format it at all.
Trust me, I have this card and it works flawlessly since I got it exchanged !

I did exchange it already, the 1st one truly was crap, far worse than the 2nd one, the 2nd one was slightly better but still crap. So I decided to ditch Kingston altogether.

Lexar cards
I've had good luck with a lexar class 10 32gb cards. No one I know has any transcend cards though.

I can't use Transcend micro SDHC 16 GB class 4- I had to pull the battery almost always after using an app that accessed SD (camera, gallery, music player etc)

I've found that samsung has been a dream with good speeds and no issues (as of yet...). As for the Kingston i got a class 4 card and that worked fine for me.

Yeah, I was pretty certain it would work. It has worked on every Samsung Galaxy ever made so far. I think BestBuy had it for $70 one time. Still waiting for that deal to come around again. It might take a while...
But then again, 128GB might be better. It would be nice to carry every episode of all my favorite rewatchable TV Shows and all the TV Shows and Movies I plan on watching some day. Might take 2TB. Someday...

Wow crazy space. Let's hope they make batteries in the future to allow us to make use of all this video space

I put the same one in mine, when I saw that deal. Works fine. However as a word of advice from wasting time..........
Many state to use the sdcard.org's formatter which then formats it correctly and then put your data on it and then put it on your phone. However that doesnt work. sdcard.org formats the card as exFat and the phone cant recognize that. Let the phone format it which it will do as Fat32. Then it works fine.
Many threads state to use the sdcard.org formatter to achieve the best speed, thats the reason why I did it. So despite their recommendations, dont bother, it wont work.
On a side note of reivewing it. This 64gb card replaced my Samsung 32gb Class10 card. I have to say to say this 64gb card is REALLY slow when transferring data. It took a good 1hr to transfer 32gb of data on this card. The fatest I got was around 4-6MB/sec. The Samsung 32GB card (being it was class10) was at least twice as fast. But I cant complain too much, I mean its twice the space. Im sure a Class10 version of this 64gb card will cost over $200.

Awesome good to hear, didn't think I would hit 32GB but I'm fast approaching, time to upgrade I think.

Like dixit said.... It's always best to format in the device you're going to use it in!

I'm affraid I will have to disagree with you on this. I purchased the card .. it was already formatted with exFAT. When inserted into phone, does not recognize it installed at all .. will not format, will not mount .. nothing.
I'm running Windows 7 Ultimate 64 .. does not format FAT32 unless you're doing it be command line .. however, here is the issue with that .. standard command: format ?: /FS=FAT32 for the 64GB card took 2 hours to format, only to find that it errors out right at the end stating it is not compatible and over 32GB .. waste of time.
Hense .. this is why I attached a link to a command line program called FAT32format .. I executed this program from command prompt .. and poof, 64GB formatted FAT32 .. plugged into phone .. phone recognized the card, no problems at all .. I did however reformat the card via the phone afterwards.
So, for the initial installation (out of box) our phone WILL NOT see it until it has been formatted FAT32

Well mine had no problems reformatting on the phone itself. When I first put it in after the sdcard.org format it was exFat. Phone as you stated didn't recognize it. Then I just on the phone told it to reformat it. It did it just fine as Fat32. But either way like you said as Fat32 it has no problems.
Dixit

The only issue here is that you can't transfer files larger than 4Gb to the card when its FAT32. Something to keep in mind if you have large files.

I bought mine about 6 months ago and haven't hd a problem with it in any android phone and I formatted it in the phone. Now I'm just waiting on this skyrocket hd to come out and I'm selling this phone and buying that one. Has any boy heard any thing about a size bigger than 64gb

thanks for the note, it's a great price, but media-scan kills me
I love the space, I don't care about slow speeds because I usually dump data on the card (huge mp3 collection) and keep apps on the internal /sdcard (16GB)
The problem I see with this is that my current 32GB class10 card is being scanned by the phone periodically. This scan takes a LOT of time and 64GB would be even worse
If I find a phone that is equal to or better than Skyrocket + support exFAT I would go for the 64GB card in a heartbeat
Do you know such phone as of today ?

thanks for the tip on FAT32format. my 64GB card showed up yesterday and i was fearing i had wasted money since i couldn't get it formatted to FAT32. i bought it after seeing that YouTube video (we've all probably seen it) to put in my Galaxy S i'm turning into a dedicated PMP. the phone wouldn't format it (would try but it would always say damaged) but this worked like a charm. i'm transferring my music collection as i speak. thanks again for the help!

Browsing this thread and checked out the Best Buy link. Price is $79.99 as I write this.

$71 on Amazon now.

Adorama Camera $59.95 and free shipping if anyone is interested.

^^^^ thanks for the link, i have a few friends looking for this

Just a thought, cuz I haven't noticed anyone say this but from what I've read class 6 and 10 cards are not ideal for mobile phones because they are optimized for faster sequential read/write (ideal and fast for cameras). Class 4 is faster at random read/write than 6 and 10(ideal for phones).
I just purchases a sandisk 32gb class 4 and I've never had it randomly scan and I use it for music, photos, some app data, backups etc.

this is unfortunately somewhat true. Class 6 in the OP should be okay though. I'm currently in an RMA process with Sandisk and in talking to their Technical support they said :
"We need to take the few information from you in order to process the RMA request. There is an ongoing issue is with Sansa Ultra 64 GB SDXC class 10 Cards the one which you have and on Android phones we need to use the Sansa Ultra 64 GB SDXC class 6 in order to make it functional. It depends on your requirement so please let me know so we can proceed with the request."

THANK YOU! So much, you helped me out of a jam. Found a SanDisk Class 10 online for $64 and was freaking out when my phone wouldn't recognize it but using the FAT32format program through the Command Prompt worked like a charm so my deepest THANKS! :good:

microSD

I bought this for my phone, and it is not working Lexar 32GB Mobile Micro SDHC Card- Class 10

I don't know what cards would be compatible with this phone, but in the past I've found that formatting a card on my PC has sorted non-working ones out on my phone. Have you tried that?

Yes i've tried formatting it in all possible formats.

sandisk worked
The sandisk one worked for us:

known bug - microSD not working
According to several Nokia.com discussion threads, this is a known bug with the 820. The card might work for a few minutes, but soon goes corrupt. The card can be re-formatted OK in a PC, and phone will recognise it again (but only for a few minutes). If you've changed the settings to store photos etc on the card, the camera will also stop working when the card goes corrupt (because it can't store the pics anywhere).
Apparently a patch is due one day to fix this...

I can confirm this through experience. Pretty bad issue since the phone only has 8GB of internal storage.
I have tried the following cards and have had the same exact experience:
Sandisk Ultra 64 Class 10
Kingston 32 Class 6 (I think)
Trancend 16 Class 10

For me, the SanDisk Ultra UHS-1 with 64 GB works fine WHEN I reformatted it on the PC to fat32 with this tool: fat32-format.softonic.de
Before, the phone recognized it, but crashed and I couldn't move files to it. After formatting, no more problems

I have this card here
SanDisk Ultra 64 GB MicroSDXC Class 10 UHS-1 Memory Card with Adapter (SDSDQU-064G-AFFP-A)
Worked as soon as it was inserted to the phone and I have several videos and photos on it. 58.X GB formatted capacity. I would not recommend using a card that is NOT listed as compatable with the phone.

TurboTuck, thanks for the info.
Have you loaded the microsd with more than 10Gb? Issues usually occurs when more than this amount is loaded to the card.

...mine is working perfectly with a 16 GB class 4 microSD sandisk card.

Anyone tried a 32Gb class 4 microsd?

Just to throw in my .02.. I reflashed my 820 last night and the SD card is still working fine.. It is an 8 gig class 4 I believe. I have a 16 gig class 10 somewhere that I will need to try.
I'm still holding off on really celebrating, though.

Kingston cards work always for me
16GB class 10 here

I bougth a Sandisk 16Gb class 4 and it´s working perfect.
I already loaded it with 12Gb and has no lag at all.

I have 32Gb class 10 from SanDisk. It works perfectly not in 1308 and former.

[Q] Using a 64GB microSD?

First thread, so putting that out in advance.
I download ALOT of music, and since I wanted to sync lots of music from spotify to my phone and bring a few movies for traveling, I bought a Samsung SDXC 64GB class 10 microSD card from amazon on bf.
I've formatted it to fat32 (with guiFormat on windows and android itself), and my atrix will reconize it. But once I start syncing music to it it unmounts it after a variable amount of time.
Has anyone else been able to get a 64GB microsd to work with their atrix?
Thanks!

i dont think it would , since specs says the phone can handle up to 32 gb micro sd card , and never readed someone report about a working 64 gb micro sd card
sent from the gray stuff inside my skull

On the bionic, they say it works.
http://forum.xda-developers.com/showthread.php?t=1458992&highlight=64gb
Aren't the bionic and atrix 2 the same?
Also, I'm running magic mod jb. I read somewhere that 4.0+ has issues with sdxc, could that be an issue?

Try formatting with a different allocation size to see if it works.
Atrix2 doesn't support NTFS or ex-fat, which some other phones do.

Yeah class 10 cards are known to have issues with this phone. It really has nothing to do with it being 64GB or not, that is causing it to dissapear or unmount, but the fact that it is a class 10 card. We have had way too many issues with anything higher than a class 6 card in the atrix2. It is also noted that the atrix2 really technically does not support SDcards higher than 32GB, but I have a 64GB card that I use in several of my phones that seems to work ok from time to time, but I only use it to move a file from one of my other phones to the A2 once in a while, so long term I really don't have a lot of info on that.

Ok, that makes sense. Too bad they don't sell class 6 anymore. So I should try to find a class 6 32gb card then instead of 10?

anything that is class 4 or class 6 is know to work with out issues, no matter the size.
I have 2 class 4 32GB cards that I bought just for this phone that were like 30 USD 6 or 10 months ago, so I am sure you can find a few really cheap now. I know that the whole class 4 or class 6 and the speed thing really tend to turn people off, but I can copy 20GB of music to one card in just over 1 - 1.5 hours, so it is not too bad.
