Recovering pen-drive data

[Ramprasad Joshi]

An 8GB pen-drive got corrupted; how or why is not known. It was used exclusively on W*s machines and users have never noted other details about it or the last usage history. All that is known is that while copy-pasting a file from folder to folder, it worked well. The file (a CorelDraw(R) figure) could be opened and saved after updates. But after that the pen-drive could not be opened. It was removed with "safe to remove" clearance. On GNU/Linux it shows up to be unmountable due to filesys/superblock errors.

I could raw-read using dd and 8192 block-size, but what next? Any way to recover the data when fsck says vfat corrupted, logical sector size (1872) is not a multiple of physical sector size?

Sir,

While we might be limited by knowledge of the filesystem of the device, 
Will it be safe to assume it was NTFS, and formatted from a windows machine? In that case you might want to ensure that the NTFS-3g software on your Linux is updated and working. Some fat32 formatted from mac systems also do not work out of the box on Linux.

Meanwhile, you could always do dd and backup the rawdata on your hdd. Subsequently trying to format the pendrive will tell you if the damage to the device is physical or otherwise. You can manually try to mount the dump then on your mnt and see what that leads you too.

Gparted is one useful tool which has helped me sometimes. Though the data on pendrive was never very important for me to warrant putting too muvh effort.

Thanks,
Bhaavan
