Once i twied to browse the my drive and found that /shares/internal became empty. /etc/fstab contains correct mount record, but partition aren't mounted. Also i try to mount partition manually and mount tool returns something about partition fs type unknown.
After that i'm extract HDD from the box and install it in the desktop and scan with PartitionMagic. All partiotions was founded by PM and fs types was detetected except /dev/md4, its type was marked as unknown.
I thinked that partition was not correctly unmounted and tried to fix this with fsck utility, but it only returns something about partition is zero-length.
I have no more ideas. =( Can anybody helps me? I know, that I can format this partition and use it, but i want to save my data and know why this situation can take place.
Sorry for my poor english T_T
