Re: [Bug-ddrescue] HDD Image Too Large

Your drive has an internal problem, possibly a firmware issue.

Can you show us the output of the ATA Identify Device command? Smartmontools can do this, as can CrystalDiskInfo and others.

Can you also retrieve a SMART report?

If you would be prepared to indulge me, I could help you try to retrieve the drive's firmware modules. This will help us to determine whether there is anything we could do at the physical level to get your drive to the point where ddrescue will be able to work with it. There is no "logical" software tool which will be able to retrieve a single byte from your drive in its present state. Therefore I respectfully suggest that you stop hammering it with ddrescue and others.

I'm trying to rescue a HDD and I first issued this command:

# ddrescue -vv --no-split /dev/sde /mnt/flash/sde.img

GNU ddrescue 1.16

   opos:   185150 MB,     time since last successful read:       0 s

Actually, the capacity of the drive is 160Go, so something is wrong. As
you see, I canceled the ddrescue command at 185Go.
