10.4: Recover a dead hard drive using GNU ddrescue
Authored by: jklos on Jul 31, '05 03:06:24PM

That's cool that it works, but although nitpicky, this isn't a "Linux" tool. Linux is a kernel. Most of the rest of what people call Linux (ie, the rest of the OS besides the kernel) is GNU. This tool is GNU. Linux has nothing to do with it.

recover more blocks using 'raw' devices
Authored by: krishna on Jan 08, '06 10:45:07PM

I just finished recovering (under a linux box I set up to be dedicated for the recovery operation) a fat32 partition that was giving me errors on what appeared to be multiple blocks. Then I followed 'info ddrescue' 's information on setting up a raw device and retrying the recovery, it came down to a single 512-byte sector (!) that was bad and producing multiple block errors.

So if I can find which file that block belongs to, I have my whole partition back. While ddrescue's not a linux-specific tool, that valuable 'raw' information in the documentation is definitely linux-specific; so I wouldn't say I wouldn't say ddrescue has *nothing* to do with Linux, since it definitely seems to be the chosen platform for testing. Of course, information on raw devices under macosx would be awesome to have.

On OS X, raw disks are:

/dev/rdisk*

Block devices are:

/dev/disk*

If you use rdisk, ddrescue will pull the data MUCH more quickly--of course, depending on the state of the drive.
