[AT&T Samsung Galaxy S II Skyrocket SGH-I727] NoSpamDan:
+1 This is my DD again too. Great ROM.

Not that I expect an answer, but I have had a weird issue occur on this latest 4.4.270 build (seems I'm just a weird issue magnet LOL). I have a Class 10 official Samsung 64GB SD card purchased through Amazon (unlikely a fake) which I formatted as FAT32 in my PC. It has been working perfectly across ROMs for a couple of months... until now.

My 64GB card had maybe 33GB of data on it, and I have been using PhilZ recovery to backup previous ROM adventures (nandroid) and switch to, now, this ROM. After flashing the ROM, PA mini-modular GAPPS, and some TBO inverted GAPPS, everything was good and fast. I restored all my apps, rebooted several times, and had full access the entire time to the files on my External 64GB SD card.

I'm not sure exactly what could have changed as I haven't installed any new apps that I wasn't using before, but when I rebooted to recovery to make a nandroid of this new BS with my settings and data, my /storage/sdcard1 was inaccessible (note no nandroid created yet). When I tried to mount it I kept getting an error. I couldn't open the Aroma file manager since the files were on my external sd. So I rebooted and wouldn't you know, in the ROM the card was not mounted, nor could I successfully mount it.

I ejected the card, put it in my USB adapter, and put it in my PC. All my files were there still. The only thing that stood out to me is that the card was just over half full. I have read that the FAT32 file system supports file sizes up to 4GB, and with long filenames in use, up to a volume size of 2TB. Everything on the card is within these limitations.

Lost for what was going on, I deleted a few nandroids to get the used space down to maybe 24GB, and when I put the SD back in my phone and booted, the External SD was again available. Taking advantage of this, I created a new BS nandroid, with the card recognized in recovery again. After backup, I rebooted the phone, and again the External SD card was missing, and unable to mount within the ROM OR recovery.

I'm not sure what I may have done wrong here. Maybe a PhilZ setting I missed? I use the CWM default backup format, and have always used that. I even tried updating to the latest PhilZ for the SR and there was no change. It seems that there could be some internal link broken or missing somehow, idk.

Does anyone else running this ROM have a 64GB External SD card?

Has anyone else with a 64GB card on the SR successfully filled it more than half-way with data?

Could there be a file, hidden or not, placed on the External SD somehow that could cause this behavior?

Maybe some policy handling access of the External SD card in the latest commits synced to build this ROM?

Any help/recommendations are appreciated. Thanks

EDIT: Currently reformatting the card as a test...

EDIT2: Formatted the card again as FAT32 and copied all my files back in. 2 reboots later and it seems to be working, both in recovery and the ROM. Trying nandroid next and will report back if that causes the issue to resurface.

EDIT3: Following nandroid, card is still accessible in the OS and recovery. Not sure what caused this, and sorry [MENTION=4559825]wantowan2[/MENTION] for cluttering the thread. As far as I can tell, this was NOT a ROM issue...
