Lo,
been getting a white screen with a line along the top before the device resets itself and wondered whether this could be donw to the SD card itself or the file format.
I have the SanDisk Mobile Ultra 64GB Micro SDXC UHS-I Card Class 10 and it's formatted with whatever was the default file system.
What's other people's experience with the card?

I used to have the same problem but it was due to an app. Plus now I usually perform a cold boot to prevent any problems.
To perform cold boot, do the following:
1) Power off.
2) Hold down volume button and the power button.
3) You will enter a screen that shows 'wipe data' and 'android' option. Don't select anything, it will cold boot automatically.
If the device booted normally without going into the screen with 2 options, it did not cold boot.
You do not lose any data by cold boot. It just refreshes the system cache.

It seemed to be double twist with airsync. My device kept restarting every 30 mins or so.

I have a 32GB microsd formatted in ExFAT as well with default allocation size. No problems with it though.

Yeh,,just wondering if it's due to it being 64gb though. I'll leave it out for a bit and see what happens.

Removing the storage card while the phone is on
When you need to remove the storage card while the phone is on, unmount the storage card first to prevent corrupting or damaging the files in the storage card.
Press HOME > MENU, and then tap Settings.
Scroll down the screen, and then tap SD & phone storage.
Tap Unmount SD card.
Remove the storage card by following the steps in “Removing the storage card”.
How the hell do you remove the storage card without turning it off...
The card is under the battery
Lol. You figure as long as it took they could have proof read the thing

Too funny. I haven't looked but is it really under the batt? I know w/the Eris it's on the side, so I just have to pop the back off the phone but don't have to take the battery out.
Can't believe they'd do that (well, I mean, I can, really lol).

Most phones will run without a battery but with a charger plugged in. I know when I develop on Android, I will remove the SD card while the phone is on for my phones.

I put my 32 GB microSD card through a ****load of tests on my desktop to ensure it works (http://www.iozone.org/ FYI, increase to like 30 GB and let it run all night on your desktop). It passed with flying colors, not one skip. I did this because Newegg reported a bunch of QA issues with the 32 GB microSD cards. I wanted to ensure my Wintech card was working flawlessly. It was in my PC.
When I got it in my HTC Arrive WP7, upon the first few videos syncing to the device, Zune reported that my device has stopped responding. It did this a few times after connecting and disconnecting. It even reported a write error at one point. Bad sign...
Then, as I was using the phone, it seem to have 'delays' from starting applications. "delays" from accepting things I click on, before taking action. "Delays" when hitting the back or start button. All of these delays showing a "black screen" for like a full second. Nothing like the rock-solid smoothness I experienced with the phone stock. Something was a miss, and that annoyed me enought o investigate. Reminded me of my HTC Android device (oh *snap*).
What I ended up doing was doing another hard reset, but still had the issues - even before the syncing. There is another option to do a hard reset at the initial bootup. So that's what I was attempting, and here is where I found Calculate CRC Checksum!
Inline Pictures are from this thread
1. With the device powered off: Press the power button and quickly press-n-hold both VOL UP and DOWN volume keys. You will be prompted with a white screen and writing.
2. Go ahead and press VOL DOWN to restore to factory defaults.
3. Let it cycle and press-n-hold VOL UP and DOWN again to get back. Back at the white screen again, press VolUp this time.
This forces a Calculate CRC Checksum to begin. This takes like 30s or a minute or something. Wait until it is done, it will tell you witha benign message of some sort.
EDIT: Turns out, I still have issues with random reboots.
After a lot of research, I've found that you cannot get the fastest "Class 10" kind of cards. That actually ends up hurting you because manufacturers end up sacrificing random access times in order to get the faster read/write.
With our WP7, it's all about how fast you can find the data - not how fast you can read the data.
I've now ordered a Sandisk 32 GB Class 4, as sandisk seems to be the gold standard - and the OEM card is a Sandish 16 GB Class 4.
I'm experiencing exactly the same issues with an SD-Card from Toshiba (Class 4).
Please let us know if it works with the SanDisk Card.

I will let you know!
So I took the plunge and tried to root a Nook 8GB today. So far I have done the following: (1) created the CWM microsd card; (2) copied the latest CM10 and Gapps roms to another microsd card.
I used thes Ray Waldo instructions for creating the cwm card:
root-nook-tablet-with-cwm-sdcard
So, I am having a problem with getting the Nook to load the CWM microsd card. It just won't start when the microsd card is in. As soon as I pull out the microsd, it starts without any problems.
I tried formatting the CWM microsd card and copying CWM again, but it hasn't changed anything.
I have a Nook 16GB. Should I try the card out on that Nook?
A couple of issues that I noticed through the process:
(1) CWM file is supposed to contain 4 files? However, part C., step 7 says "Copy all 5 items in the “CWM” folder (from item B.3 above) to the window of the new SDCard" Is this just a typo? Or is there a missing file?
(2) In Part C, step 4, after the flags have been selected, there is supposed to be a green checkmark. I see a check mark grayed out. It never goes green. (Click on the green checkmark (in the upper section of the GParted window) to execute & allow GParted to complete the action)
(3) Its not really clear to me how I am supposed to boot the nook so that it will boot off the microsd card. I understand that I am not supposed to insert the card while the nook is on because the nook will mount and write data. I have seen a couple of different versions for booting: (1) just insert the card, press power, and let it boot; or (2) hold down the power button and the N button, let go when the N on the screen goes away, and then let it boot

/2012/02/how-to-root-your-nook-tablet/
Step 4 reads: Turn your NOOK Tablet on. Put in the ROOT microSD card you created in Step 3 into the NOOK Tablet. Turn the Tablet off. When it’s completely off, hold the power button and the N button at the same time. Keep holding it. This is the N button: You should see the usual NOOK boot screen with the grey N in the middle of the screen. Keep holding the power and N button. When that grey N flashes off the screen you can let go. The NOOK Tablet should be off again because you were holding the power button. Turn the NOOK Tablet on. After a moment you should see a white screen with a cardboard box on it. When it finishes you’ll see a screen that says CWM-based Recovery.
Not having gotten any feedback, I decided to go for it and tried it on my 16GB nook tablet. Worked like a charm. Not a single speedbump. Maybe there is something wrong with the 8GB nook. I tried different sd cards, etc. No luck on the 8GB device.
One of the first things I did on buying my new Galaxy Tab 2 7" (GT-P3100, Wi-Fi and 3G; Spanish market "PHE" identifier, came with ICS 4.0.3, no updates available either through Kies nor OTA) was to encrypt the Device. It worked.
Then I rooted the device with CF-Auto-Root, which had the side effect of performing a factory reset, and as I understand it from a brief conversation with the author of (the excellent!) CF-Auto-Root this was an expected side-effect of the device having been encrypted at the time of applying CF-Auto-Root.
So, the Tab 2 is back to un-encrypted.
Here are the details:
Android 4.0.3
Baseband version 3.0.8-CL448962-user [email protected] #1
Build number IML74K.P3100XWALD2
But now I'm trying to encrypt again (either/both the SD Card and the Device itself) and I'm having no success at all.
On trying to encrypt the SD card, each time it always returns "SD Card Encryption Error" within a few seconds. (And indeed thereafter I always get a Notification about "SD card encryption error" any time the SD card is mounted by the device). If I go back to Settings -> Security -> Encrypt SD card and select to decrypt the card (even though it's not really encrypted), then I can access the SD Card again - no damage was done (and no encryption either).
If I try to encrypt the Device, I get the black background with the large green outline android, and ... nothing. The green android on the black background just stays there. After the normal screen timeout, the screen goes completely blank; I tap the power button, get the usual unlock screen, unlock it, see the green android again ... and, nothing. If I rotate the tablet, the android rotates. If I tap the power switch, I get the silent/ flightmode/ reboot/ turnoff menu. But nothing will get me back to the normal user interface, and it never finishes encrypting (I really think it never starts).
Eventually (after more than a couple of hours) I give up, tap the power switch and select to reboot, and it comes back up fine, but not encrypted.
One of my main reasons for getting the newer device was to have encryption :-/
Is Encryption (Device, and SD Card) supported/ functional when CF-Auto-Root is in use on a Samsung Galaxy Tab 2 (Android 4.0.3)?
How do I get encryption to work, for both the Device and the SD Card?
Is there a way to get more detailed logging (the Tab is rooted, and I have command line access) and/or to command the encryption from the command line, to see what's really happening?
Thanks!
Hm, I tried encrypting only NEW files on the SD Card now, and that seems to work.
I stored a new file on the SD Card, unmounted the card from the Tab, put the card in a card reader on a desktop computer, and indeed the contents of that file are just "data", not readable. Back in the Tab, the contents are the picture which I'd saved to the card.
But still attempting to encrypt the existing files on the SD Card fails. And still attempting to encrypt the device does nothing (green android appears, but no % complete ever displays, etc, just as I posted before).
One step further with the external SD Card; I copied off all of the data, formatted the card, and then was able to fully encrypt it (and copy back my data).
But the Device itself, I still can't encrypt at all - just the same as before.
No ideas? None? Nobody? Please....?
Thanks,
-Jay
Bump?
sigh
Try the same thing with the device itself.
Do a factory reset.
Not once,twice.
I know u lose all data.
But try it.
And do this without android to start.
Keep press power+vol up.
Get into menu and do factory reset,wipe dalwik...all.
Hope this help.

This was over a year ago, and I don't even use the device anymore. Sorry, can't help.
I've since then tried a ZTE "Skate Pro" (the Movistar Spain branding of the "Blade III"). Piece of Sh*t phone. Support encryption natively under Android 4.0.4, but if you do encrypt the phone, the performance of the touch screen becomes unreliable, frequently so bad that swiping (including Swyping) actions don't work right, and you end up less moving things on the screen and more, effectively, tapping things you absolutely did not intended to tap. I discarded the ZTE Skate Pro/ Blade III.
Then I tried a Haier W708, dirt cheap; not a powerhouse, but satisfatory.
And a Nexus 5 which kicks *ss all over the place.
I can't help any more with this thread, and any results in this thread would not longer help me, so I'm dropping off the thread now.
Best of luck to all.
Strange issue with my phone. Got off the plane in KC, turned it on, then walked into the terminal. Was using work email and hit the home button to get back to the home screen. Nothing. Recents button doesn't work either.
Rebooted the phone and everything works. 10 minutes later, home button and recents (left soft key) stop working. Another reboot, good for 10 minutes, same problem.
I want to do a factory reset, but work forces me to encrypt my SD card. I uninstalled AirWatch, go to Decrypt SD card in security settings. Get to the page to execute the decryption and push "Decrypt SD card". Nothing happens. Thinking it might be a dead zone at the bottom of the screen because the button was right above the home button, I flip the phone 90 degrees. Press "Decrypt SD Card", nothing.
Now I can't factory reset or I can't access my SD card.
Thoughts?

Will it let you copy SD contents to a PC?
Then you could just wipe and copy back / encrypt again

Hmmm, so it would decrypt to copy? Are you sure I wouldn't get an encrypted copy on my PC, then wipe the phone and be unable to decrypt? I guess if I can see the files on my PC, then they have to be decrypted....

That's what I'm saying, find a way to copy them obviously decrypted, to the PC, then you can wipe and sort everything out
Afaik the main storage on the S7 is encrypted by default, and it has no problems copying things from there to PC decrypted
Can't speak for SD Card, not tried

So that worked. Data is over on my PC and I can read it, so it is not encrypted. Perfect, right?
Time to factory reset. Go into settings and click the box to format the SD card as well and hit factory reset. Nothing. Nothing happens. What the hell is going on here? Can't use Home or Recents button, can't decrypt SD card, can't perform a factory reset. Malware?
Just going to reset it from the recovery menu I guess.

No idea what's wrong, possibly just something has corrupted, strange one, have you got any screen overlay apps installed like blue light filters? They can do that
If you can view, open, read the files on the PC they're no longer encrypted
I noticed yesterday that indeed the home button and menu/recent buttons were working strangely
- HOME opened the google now, even though Apex is the default home app
- Menu opened recent, both with long and short click
After a reboot this seems to be corrected, but I still find it strange. Not rooted that device either.
Late response but my s6 and s7 have had this happen with airwatch. Something glitches when time to change my pin.
The phone will just turn off, screen only. Turn it on, log in and home and recent buttons don't work. Trying to manually change the pin will make the soft keyboard not come up so you cant change pin/pass, but clipboard works if you happen to have something useable in there.
Best option, although I am one of the admins, is launch chrome, request desktop, go to our airwatch portal and clear/force a pin change. Phone flickers and home/recent works again. I have to do this every 60 days or so. It's happened 4 times now.
Maybe there's a UFO near you.
Joking aside, do you have Direct access turned on and set up, under Settings - Accessibility?
