 |
|
Hi, im facing something curious. I copied data from an ext3 partition to an other in fat32 format.
The probleme now is when i mount the last one i can only see a empty "lost+found" folder. I don't exactly know what is the purpose of this folder.
I have visualise hexadecimal content of the partition, and i saw that my datas are still here. I can simply just not acces it.
Im asking for softwares wich will help me recovering my hidden data. |

The purpose of lost+found is basically to give fsck somewhere to put chunks of data it recovers when told to do such things as it is checking or repairing a filesystem.
As for the data on that partition, why not fsck the partition, checking for bad blocks, then recopy the data from the ext3 partition?
Failing that you might find mundelete to be of use. A quick set of searches yields no ebuilds for it or similar packages. |

lost+found probably got copied from the ext3 partition, or you may be looking at a freshly formatted ext2/3 partition.
check which kernel module your loading. There are two. fat and vfat. fat doesn't support long filenames. I've heard that mounting a partition with fat instead of vfat could cause problems.
| Code: |
grep FAT /usr/src/linux/.config
# DOS/FAT/NT Filesystems
CONFIG_FAT_FS=y
CONFIG_VFAT_FS=y
|
y or m is ok.
If m, use this to see if vfat is loaded.

| Using the fat module instead of the vfat module should not result in the files not being listed; it should however result in the files being shown with names which have been mangled so as to fit, uniquely, into the 8.3 name format FAT used prior to VFAT. Please note the occurrences of should in the prior sentence before entering righteous indignation mode when replying. |
