When I tried to update my CM nightly (think it was 14, was last week some time) build to use the then current incredikernel (wiped cache and dalvik as I was supposed to), my phone got stuck after booting. The checking sd card icon was up in the taskbar, and trying to unlock or do anything else caused things to freeze. No amount of waiting helped.
I was able to use recovery to restore a previous build from that same SD card, but had the same issue with a known working image.
I popped out the SD card and was able to boot fine. I then used recovery to format the SD card, and it loaded again- so I figured something got borked during the kernel update somehow.
In any case, now when I start up my phone it unlocks fine, but the checking SD card remains for over a minute, where it used to only take a few seconds.
I think I'll be buying a new SD card, but wanted to ask around to see if anyone else ran into anything like this, or if perhaps this is expected for new CM7 nightlies or something.
I forget the brand, but it it some generic 8GB SD card, worked fine since I got the phone when it was first released...
Turned out to be that formatting the card from within cwm recovery 3.0.0.8 seems to have used very small allocation size, which males the startup validity check stuff take forever.
I formatted via windows instead, and works much nicer now.

Is anybody else experiencing repeated failure of micro SD cards? EVO has been rooted and working great since last year. Suddenly, in February, my 32GB sd card failed on a reboot from flashing an early CM7 ROM. The Message is "SD Card blank or has unsupported filesystem." I called Sandisk and they sent out a replacement. Two weeks ago, same failure. Called Sandisk again and they are reluctantly sending another card (supposed to arrive today). In the meantime I was running with my 8GB that came with the phone. I just installed the stable CM7 release, restored data via clockwork and BOOM! SD card failure again. So, is anyone else getting this? Three SD cards in 2 months is kind of extreme. I'm trying to determine if it's the hardware, the ROM, or a series of bad cards (unlikely).
Some additional details:
All cards are Sanddisk
Recovery is ClockworkMod 3.0.0.5
HBOOT is 0.93.0000
Card is not readable via a card reader
its a bug with CM7
Thanks. I searched the forums, but was unable to find anything. Do you have a link to a discussion about it? Thanks.
sorry i dont have a link, it was some thing i read. a simple reboot was the suggestion and it worked for me also. good luck to you

I have had a similar problem with my 32 gb card.
Patriot card, Amon Ra 2.3, hboot 0.76, card worked in my laptop, and now is recognized in my phone, but Titanium backup will not recognize any app data elements
Delete the LOST.DIR on the sdcard while in recovery. Tends to fix it.
I posted this in one of the accessory threads, but it probably belongs in here.
------------------
I got a lexar 32gb class 10 microsd about a bit over a month ago. The first one worked great for about 3-4 weeks, then I started getting data corruption. Reformatted, copied data back, lasted 3 days. Now mind you, I always shut the phone down properly.
Rma'd it, got the replacement. Lasted all of 2 days before file corruption began again.
Lexar insisted I send my old one back before the send a replacement out. Fine. This ordeal took nearly 10 calendar days. During this time I had the stock sandisk 8gb class4 card. The data copied to the lexar is identical to that which was on the sandisk. Only difference is, I had no corruption what so ever with the sandisk.
Thus far, the conclusion i've drawn is that these bigger cards (or faster?) don't seem to work well as a virtual hard drive. They may be fine for storing pics or mp3s. However, the evo uses the sd card more so as random access read/write type storage, with the card constantly being updated by receipt of email, and other system programs/processes. Maybe this is what does the card in.
finally someone with the same problem as me...i thought i was the only one my 32gb card does the same was there a fix for it??
My 16GB Transcend card just died a couple of days ago. Sending it in today for replacement. I can access most folders from a USB card reader, but the larger folders can't be accessed.

This is actually very interesting. Earlier this morning I was thinking about App2SD and started looking into using it, and saw comments that peoples cards were getting nuked after using it (albeit only a few people). This kind of jives with the above quote... but take that sentiment with a grain of salt, admittedly I'm still an Android noob.
To those who are experiencing corrupted card issues, are you using App2SD?
Wrathx, I am set up with an ext3 partition using the dark tremor's a2sd scripts. I only have the apks on there however. The rest of the /data content (config files, databases, etc) is still on the phone's internal memory - for the same reasons above. I figured the internal memory is better (faster?) equipped to handle ever changing content. So in essence, once the apk is on the ext3 partition, it's accessed as a read only process.
My 8gb stock sandisk card is partitioned identically to the way the 32GB was, 32mb swap, 512 mb ext, and the remainder as /sdcard. It's also being used in the same way (only apps moved to it, no other content). Again, no issues what so ever with it.
Now, the the cache and dalvik cache are both set up to use the phone's internal /cache partition (for reasons above). I mention this because dt a2sd script gives you a number of options on how to set this up. Some people may have their cache and/or DC on the ext partition in addition to possibly having the actual /data content including settings on there as well.
so is there a fix r is everyone running into the problem getting a replacement???
When my SD card failed I took it out and put it in my husbands phone ( LG optimus) and let it power all the way on then took it out and put it back in my evo and it worked perfectly after that. It's a 32 gb sands....hope this helps

Just blew up card number 4. This one was a brand new SanDisk 32 GB. It failed when I powered up the phone. Just as a precaution I did not do anything out of the ordinary other than put some music on the phone. Did not transfer apps to SD. I'm going to restore to stock today and exchange the phone as a precaution. Since there is no clear evidence of the cause (even though it only started happening since switching to CM6/CM7) I may just go with straight stock root for now. I'll update if that causes any failures. I seems to only take a couple of weeks to get a failure so stay tuned.

has this worked for anyone? Once i reboot i just get 'blank sdcard.' this is the 3rd card that got hosed for me. all 16gigs. really wondering if its the hc cards, cm7, or just my phone.
My repeated failures turned out to be a bad slot on the phone. I would unroot the phone, restore stock, and exchange it. Since getting a replacement I have had no issues.
Hey guys I just wanted to ask u all a question bout upgrading sd cards on the Evo. I just purchased a Lexar 32gb class 10 sd card from Amazon. I still hav the stock 8gb card that has all my data....music,movies,music videos,custom roms,kernals amd so on. I hav heard that some people are having problems with changing their cards. So my question is what is the proper procedure to getting this transfer to be successful. Is it better to format new card thru windows or phone? Do I need to partition the new card? What is the easiest procedure to transfer my 8GB card stuff to my new 32gb card. The reason Im asking is I dont want to corrupt the new card in anyway...as u all kno they are NOT CHEAP!!! I just want the transition to workout smoothly with NO problems. Any advice wud b much appreciated. Thanks Yall!!! Evo runnin MikFroyo v4.61 w/ netarchy-toastmod-4.3.4-cfs-havs-more-nososbc...overclocked to 1152mhz.
Copy the contents of your current card onto your computer or an external drive. Shutdown your device. Remove your current card and replace it with your new card. Make sure your device supports the 32 GB size. Reboot your device. Many cards already come formatted, however, it wont hurt to reformat it to be sure. When your phone finish booting up, go to the SD card and phone storage setting within the menu. Select unmount SD card. After it unmounts, the option to format it will appear. Select format. When finished, select mount. Back out of that menu back to your homescreen. Connect your device via USB to your computer or external drive and transfer the items you copied to your newly formatted card. Reboot your device when you're finished. You can also format from your computer and from within recovery. Take your pick.

If am not wrong EVO supports max 16 GB and EVO Shift is 32 GB
^You're mistaken, the EVO does support the 32gb.
Says so on the HTC support page for EVO
Whew, you had me scared for a moment... I just ordered the same 32 gb microSD this morning. :]
I've been through 2 lexar 32gb cards. Within a matter of weeks to days, I was getting data corruption. Not sure if it's limited to the lexar class 10 cards, or any class 10. It would appear to function fine at first. At some point during the day i'd go to check my email and get a sd card mounted in read only mode message on the status bar. Rebooting would usually not help. Had to hook up the phone to the pc, mount the sd in recovery, then run a chkdsk. I'd typically get many many corrupted files.
Now mind you, i'm always careful to shutdown properly, only mount the sd when recovery. I've come to the conclusion that there is some incompatibility issue either due to the size, or perhaps lexar's ability to be downward compatible with the slower speed devices (I think the evo can only take advantage of up to class 6 devices).
Lets hope you have better luck than I did, but after multiple corrupted files, I'm back with the stock card, which has caused no issues at all (besides being low on space).
i have 32g patriot class 10 card and it works great for me. i just transfered my old sd card stuff onto my computer via the card adapter it came with. i inserted and formatted my new card into my phone. and transfered everything from my computer tomy phone via usb.
Ditto on the formatting with the phone. Since i am using ext, it had to be via the phone as I don't have the right tools to do it in windows.
FWIW, with the initial lexar card, there were no problems for nearly 3 weeks. With the replacement card they sent me, issues started showing up 2 days later. Could be my phone is less tolerant of media quality than others..
one thing you need to remember when copying the files, is to hit the option to see the the hidden files on your sd card, if you dont your phone will have glitches because it will be missing those files, because when they are hidden they dont get copied
Hate to hijack here but it's along the same lines.
If I don't listen to music or take a bunch of pictures what if any difference will I notice upgrading my class? Sorry I am coming from a Vibrant that had 14gigs internal and the sc card was purely optional.
I was thinking about just getting an 8 gig class 10 if it would make a difference.
pc to dupe sd card?
Could you just copy the sd card using an adaptor to your pc hard drive, then copy the files onto the larger sd card, again using the adapter in the pc. then install the new sd card into the phone? I am new, to this, i'm just askin.
blairan...I think you wud b safe to do that but u must format the new sd card first via phone(itself) or thru windows before any transfer of data is made. My question was simply that I hav read that many people hav had complaints bout corrupted files being present thru their new cards. Or problems with "read only" errors and not being able to access things on the card. If u are rooted and are running a custom ROM that allows Apps2sd to help free up internal memory on ur phone then u wud also need to partition the card as well to allow that. I just dont understand why their have been so many people having these problems with the 32g class 10 cards.
blairan...Im pretty sure u wud be safe to do that but if it is a new card u must make sure it is formatted first via phone itself or windows before u transfer anything to it. My question was simply I dont understand why so many people have complained bout corrupted files and or read-only errors on the 32g class 10 cards. Problems that seem to arise days or weeks later after installing new cards. I wud really like to get to the bottom of it and find out why.

If anything, you'd probably notice quicker loading from apps that you've moved to the SD card. But admittedly, video, music, and photos are the places you'd see the most tangible improvement.
Doug,
I've tried this several times (I think I'm up to double digits, now) on my rooted Evo running the stock ROM. After I transfer all the files and reboot, several apps are not installed and the phone says it has a low amount of space. I've tried restoring a Clockwork Mod backup as well and I get the same thing. I have everything backed up in Astro, but when I try to install the missing apps, the low memory issue prevents them from being installed. Should I remove all my apps and start over? Should I un-root my phone and do a factory reset? I'm so frustrated I'm about to do the latter.
I'm upgrading to a 32GB class 10 card and I just can't figure it out. Any thoughts?

No, you do not need to unroot, but I do recommend you start from scratch. Since you already have the contents of your card backed up to your computer, go into recovery and re-partition and re-format your card. In amon_RA select "partition SD card" from the main menu. You will be prompted to set a size for 3 different things. Insert a zero each time. Doing so will allow you access to your entire card. Afterwards, copy the rom you want to use to the card via the MS-USB or the Mount USB option, if using ClockworkMod and flash it. Your paid apps will be listed in the Market after you've logged in with your credentials. Your unpaid apps will have to be redownloaded and reinstalled unless you have them backed up to Google's servers or backed up with Titanium Backup. Anyway, you will have a clean install of your rom, a clean install of your apps and a freshly formatted and partitioned SD card. If you still get the low memory error afterwards then I am assuming you have too many apps on your internal memory and thus, you will need to move many of them to your SD card to free up your internal memory. There are tutorials available to learn apps2sd. Anyway, I hope this helps you.

Having an issue with my T-Mobile S4. Starting yesterday after resetting my phone freezes up after I insert an SD Card into it. I leave the SD Card out and the phone runs fine, pop in an SD Card and it freezes up after about 5 minutes. I have reset the phone completely and I am still having the same issue. I have tried different SD Cards that I have and the issue still happens on each SD Card. I originally was using a 64 GB sd card and I transferred the files to each SD Card, so my question is, is it possible that a file on the SD Card is corrupted and causing this issue or is there something else going on? I have a lot of other things I could try to do to narrow it down I know but I figured I'd throw this up there to see if anyone has had this issue also.

Have you ever tried to remove the SDCARD and plug it into a card reader or into the computer and copy all files and folders
from the card to an empty folder on your computers desktop.
After that format the 64GB microsd using FAT32 in your Windows computer.
Then put it back into the phone as a blank empty sdcard.
Then check out the phone and see if it has any issues with the sdcard. Chances are excellent that doing that will fix the problem.
If it does you can copy all the files and folders from your computer back to the sdcard in the phone.
Good luck!
I have 2 64gb sandisk 10x microsd with Samsung S4 I9005 with Android 4.3. I formatted with android, also Windows 7 64bit with various types of sizes on laptop. However on laptop or on phone after writing some files and disk scanning, it gives many disk errors. Even after scancheck and correcting it.The errors repeat each time. I wonder if it is software or microsd hardware problems. There is no problem with 32 gb sandisk microsd.

Hi, I recently purchased a pny 32gb microsd. Everything works fine on the first day, but then I find a weird problem a day later. What ever I put into the card get deleted after a while. Not only that, but when I Unmounted and then remount the card, it formatted itself. Is this a problem with corrupted card or something going on with my phone system that it keeps formatting the card automatically?
I am on stock rooted 4.3.1
Thanks, let me know if you guys have this problem in the past and how to fix it.
