Solved: Storage card wiped mysteriously

[teazer]

The purpose of this thread is to determine if anyone else has seen this and if so, determine the cause.

Two days ago I flashed MightyROM 4.16 without problems. Love it btw. After a day, I started installing apps:

footprints, ticker tape, live search, google maps, g-watch, c-api-sro, my mobiler, htorch flashlight, dial plus, jetcet print 5, voice command and sonar ce. All programs were installed on the card.

Just went to download skyfire from another thread and noticed the directory structure had changed on the storage card. Instead I see folders: 131, files to be deleted, live search and temp.

Voice command and live search were the last programs used. Was using google maps half an hour before.

Any ideas on what wiped the card or created the "131" folder? Don't care to repeat history.

Thanks for the ideas.

my stock tp didit, maybe 2 months ago. didnt even touch ppc. not sure what caused it either. never been flashed or unlocked. lots of apps on ppc but i have way more on it now and all is good.

Thanks for the replies. I'm getting ready to flash to 6.5 and am formatting the 8gb card first. Noticed besides the 131 folder which takes a long time to open but appears to be empty, there is a hidden file EncFiltLog.menc that doesn't show while using file manager. Found it after plugging the card into the desktop. Perhaps one of the newly installed programs (possibly in the card root directory) activated file encryption??? The menc file shows 0 kb but I suspect it's inacurate. Going to put the card back in the phone and do some homework on encryption to see if I can save the few files that weren't backed up.

Edit to add: Memory, storage card shows the space on the card is still being used. (about 1GB worth of music files)

Found the most probable answer in a different PPC forum on the site.

Alot of times, if you check the card , you will find it has a single file with a .menc extension. This means that the phone has encrypted all the info on the phone (edit...I meant on the SD card) and it will not be viewable by any other device, and the only way out is a long an painful data restoration process that will allow you to recover most of the data off the card in chunks. Its really quite a pain in the ***...its happened to me once and to my roomate once. Since then, I make it a point not to plug in or unplug a USB cable unless I am POSITIVE that the card is not being accessed by the phone.
