all files on sdcard disappeared but are still taking space on the partition

[nergal]

i tried to copy some music but it blocked, i tried several times but same issue. then i unplugged the phone and replugged it. i could still see all files but not access anything. i just reboot the phone and there all files on the sdcard had disappeared !

i plugged again on the pc, i could see a few files that i don't see on the phone with the root browser. i unplugged and plugged back and there no files anymore even on the pc (of course on my options i can see hidden or system files).

Strange enough when i check partition size on the pc it says i have over 500Mo used and when i look on sdmaid (android app) it tells me that mnt/sdcard is 543Mo size. but me i can't see any files. Apps using the sdcard (like evernote) had to recreate a new folder on the sdcard. if i check folder by folder it tells me only 2.6Mo used... (LOST folder being empty)

i guess it is possible to recover all as i can see the used space but i don't know how.

i tried recuva or testdisk but it does not detect this kind of partitions

i tried some recovery softwares on android, it did not really work ("hexamobile" found a lot a of things but not the ones i needed and "undelete" found almost nothing) but i noticed with "undelete" that it proposed me 2 "mnt/sdcard" path with different results, so i guess the problem is here ! Also when i plug to my computer i don't see the folders created today, only the ones created yesterday 😕

i searched on sony/xda/google but did not find anything relevant (just one guy told me he had the same problem but could only solve it by a full reset fo the phones loosing all datas and apps)

does anyone know about this issue ?

What operative system do you use on your computer? If Ubuntu check that needed MTP drivers are installed and try again.

Else I suggest a format of the SD card and start over again to see if it fixes the problem.

windows 7  or ubuntu with mtp drivers is the same

i saw other posts about this here and no solutions were ever given to them...

i will format but i hope this problem is not coming back !
