My father-in-law came to me with a failed hard disk from a Windows system. It is probably NTFS, but that isn't known for sure. I have a few Linux machines and will try to recover what I can from the drive.
first try
- It is a SATA drive, 250GB
- It spins up when power is applied
- Linux recognizes the drive and assigns it /dev/sdf
- I try to mount it as NTFS:
mount -t ntfs /dev/sdf /mnt/bob Error reading bootsector: Input/output error Failed to mount '/dev/sdf': Input/output error NTFS is either inconsistent or there is a hardware fault...
- I try to mount it as msdos:
mount -t msdos /dev/sdf /mnt/bob mount: /dev/sdf: can't read superblock
- I try to mount it as vfat:
mount -t vfat /dev/sdf /mnt/bob mount: /dev/sdf: can't read superblock
After verifying that the disk is really bad, I wrapped it in plastic, then in paper towels, then in a ziplock bag and put it in the freezer while I look for better tools to tell me what is going on.
new tools
I added a few packages that were not installed on my system.
disktype
Detect format on a disk or partition. http://disktype.sourceforge.net
testdisk

GSmartControl
