Have you formatted the sdcard to fat32?
sent from my android powered beast!

yes i have...also it was already in fat32!!hmmm..i did make a partition of 1gb ext2 for link2sd..but now am not able to view in in the partition manager......now i have only around 6gb for use...but that doesnt matter..i just want my card to be recognized in my phone!!

Some class 4 cards are not recognised. What class is yours?

i dont know...how do i find class f the card..its sandisk card that i bought..i m from india..also initially the card was working fine..after i made the partition this morning it stopped working...also card is mounting in clockwork mod recovery without any errors...so i guess theres no problem with the card..
P.S--if i revert back to non rooted stock HTC, will this be fine??

P.S-i think i know the problem..i made an ext2 partition on the card for 1gb which it is not showing now even in the partition tool wizard..any ideas how to get it back,my ful card capacity???

solved it finally...it was a simple step...i had to make a partition in the sd card through cwm and give the swap size as 0..finally its working..thanks for ur support guys!!

No Luck For Me
I believe it may just be a hardware issue I am having. But maybe someone can point me out to something helpful.
I put the card in, it is not recognized, by either the phone, or by CWM
With the phone on, and in 'Settings' -> 'SD & Phone Storage', the card does not appear. I slowly pull the card out, and 'Mount SD' & 'Erase SD Card' both go from unavailable (greyed out), to full on available and White for a split second. After that nothing...
It does this with 3 different cards. an 8G Class 4, a 2G Class 10, and a 2G Class 4
I've contacted HTC about it, but who knows when they'll get back to me. Anyone here know of a solution?

It's as if the contacts inside the phone are screwed up. Like I said, when I pull the card out of the phone, while in the settings, it recognizes it on the way out for a split second.
I've been trying for the last half-hour to try to get it right to that point where it flashes the 'mount' to white... but I must just have goofy thumbs, because I can't quite get it...

Following you I have lost all my datas from SD card

Cannot copy anything to my sd card

Hello,
i recently bought a new sandisk ultra class 6 8gb micro sd card for my phone..but i can't copy anything to it....the drive shows in computer but when i try to copy something to it, it says "An error has occured. The destination you specified does not exist.It might be in an offline network location or an empty CD or DVD drive. Check the location and try again. "
Also, i received one adapter with it...through which i can copy stuff onto the memory card but the problem is that i can't copy anything on it directly when it is in my phone , i also formatted it twice but still no luckkkkkk
Do i have to use the adapter at all times?? is there any way so that i don't have to use the adapter??
Please Help.

There is no problem with your memory card, your phone software/hardware may has some problem.

its just doesnt work, there is a compatibility problem with some sd cards in wfs, you have to buy another brand of sd card it will probably fix your problem, but i think you should try the card before buying it in order to make sure there is no compatibility problem.

microsd card damaged suddenly !!!!

a microsd card 8GB class 4 came with my phone
today after I took a picture with the phone camera I forwarded to see but no sd card
I connected it to PC then the windows asked me to format ... I wondered the the card space became 30.6MB !!!!
and cannot be formatted .
I tried many ways to recover the sd card such as SDFormatter v3 , DriveRestore_Professional , EASEUS Partition Master , and more ... without benefit !!!
can any one explain what happened with the solutions if possible please

Try using the formatting option on your Phone, or you could try CWM to do it too.

Try doing what XD suggested, if that didn't work, try formatting with another pc

I tried to format using CWM and using 3 PC's (win7 & xp) without any benefit

That happened to me once.
if possible You have to connect the SD card directly in your computer (SD Adaptor or any SD card reader).
If you're using windows, you have to go to control panel--> Admins tools, and then go to disk partitions. There you have to identify your SD card on the list and eliminate all partitions that could be on your SD card. Then you have to create a new partition on that SD and the format it.
There you go.

Maybe, maybe not, if it's not faulty then there's no reason why it wont, and if other users on the thread of whatever ROM, kernel or both you're using have reported the same issue then I don't see why it wouldn't. Given that you've already said that you've tried everything suggested I suspect it's a faulty card, but you're never going to know unless you try.

thanks anyway for you all

Format in linux You must of tried turn you sd card into ram thing or ext overload at lease it will tell you what is wrong with your sd

Hello mates, greetings from Turkey.
i bought the following sd card and start using it in my i8150. However phone freezes / thinks a lot almost everytime when it starts using this SD i.e. during startup, previewing gallery, etc.
is this a known issue or something fixable?

for an exact solution, i formatted everything (phone, internal sd, external sd by following the "go pristine" procedure).
then put the new update zip files to re-install the rom, open the phone in CWM mod.
CWM saw the contents of the ext.sd and i started installing zip file.
CWM was saying that it is installing the zip, however it was doing nothing as there were no further progress of installation.
at that point i figured out that my phone and my new sdhc class 10 ext.sd card are not able to communicate in a healthy way.
card is working in laptop, but has trouble working in the phone. most probably card was corrupted at the first stage while i am buying iti from store.
so i am giving up this.
just fyi.

Hi,
here is what i did last hour.
formatted again in "default" format and tried to re-install rom from ext.sd.
During first attempt, attached screen does not changed for 30 minutes, so i gave up again and force to shut down the phone by pressing down power button for 8 seconds.
I thought the phone will shut down only, but it restared in CWM mode. Then i gave another try and this time phone processed the zip file.
so far no new problems but let you know in case of one.

use that Rom RemICS 1.7
and here it's the Link: http://d-h.st/xwI

Suddenly Getting SD Card Unexpectedly Removed Error

Been working fine for over a month now all of a sudden the SD card appears to be randomly mounting/unmounting itself and has become unreadable on my phone.
I've put the SD card in my PC and it works fine so I suspect my phone has developed a fault. I hope I don't have to get an exchange as it's otherwise faultless and I'm dreading getting a unit that can't be S-Off'd
I haven't modified or installed anything prior to the fault developing,
Any tips would be most welcome.
PS It's a genuine Transcend Premium 300x 64GB bought from MyMemory.

well, a simple solution is to enter recovery and see if the sdcard works there if this way it works, change the rom/perform factory reset, if this doesn't, well, you might try to flash everything again, but i's possible that the sd slot is broken...
i wish you all the luck, let me know

I would copy EVERYTHING off the card to a PC and do a format and try a different file system. I would has perform the format on the phone, to make sure its gets formatted to the correct file systems.
Long story short, It sounds like you memory card is starting to get Corrupted. I have to SanDisk cards that started doing that in the biginning and ended up not being read at all on PC nor the Phone.
Also while its doing that, youll also notice the battery start to drain more, at leasst thats what happended on my Note 3 when I had the san disk cards going corrupt.
Ended up buying new Card and now everything is fine.
I doubt is the card reader built in phone, more then likely its your memory card going corrupt.

I agree most likely the card. I'd download an sd card format tool and do a full format, don't use Windows format then do full check for bad sectors. I had a similar problem and it was the card at fault, but strangely worked ok on the pc.

I have been through many a Samsung phones and always had corrupt sd cards in exfat. One day I saw a thread that said convert to fat32 and have never had a problem since.
Sent from my HTC One_M8 using XDA Premium 4 mobile app

Thanks for all the advice.
I could read the card in recovery but it failed to format there.
I tried to format in windows but my only options were NTFS or exFAT, no FAT32. But this failed anyway also.
Downloaded a SD format application but this said the card was write protected and to move the lock switch, obviously MicroSD has no switch like standard SD.
So next I deleted all the files on the card and ran h2testw test. This failed and reported card is probably faulty.
Then I checked the contents of the card again and all the original files were back again, so it's definitely 'Donald Ducked'. I was able to get all my files backed up and fortunately I had my photos already thanks to Dropbox & G+.
So I will now look at getting MyMemory to replace it but my fear is they will want me to return the faulty card but it has sensitive information on it that I can't delete. Any ideas on how I can wipe it?

How did you attach the card to the pc? Try a usb card reader and then try again. If still problems download mini partition tool (Google) and delete the partition. You can then wipe it properly.

I reformatted the SD card from the settings within the phone and since then it been working fine :\
make sure you're using 2.0USB also..

when i connect my phone to charger
Its been few days i am noticing when i conmect my phone to charger it says 'sd card removed unexpectedly or either it suddenly stops showing content from my phone, then i have to go to settings unmount/mount the sd card frkm storage option and then it shows the content even when charging, or sometjmes it doesn'fshow option for that so on that case i have to restart my phone. What could be the possible reason and solution to that. It was fine on 4.4.4 now i am on 5.0.2 all stock htc one m8 h/k edition with sim unlock and s-off via sunshine.
