Recover a dead hard drive using dd
Authored by: aerodr on Mar 24, '05 01:46:39PM

I've tried this hint both with and without the sync option as suggested by the orginal poster and signal15 on a corrupted drive that contains Redhat 7.0 and Windows 2000 partitions. The resulting .dmg files are the expected size, but when I try to mount the images, a window pops up stating that the image failed to mount because there were "no mountable file systems".

If I run hexdump -C on the .dmg files, I can see some of the filenames on the corrupted disk, so I think the image has the data I want, but mount isn't working.

Anyone have any ideas?

Recover a dead hard drive using dd

Similar problem here, I have a drive that contained BeOS and FAT32 partitions, and I "DMG"ed it using OS X.3 Disk Utilities by creating an image from the device. My intention was to get a carbon copy of my drive in order to restore it later, but the Disk Utilities will not accept to restore it (even though the image is being restored to the hard drive it was first taken from). The DMG format (created by Disk Utilities) is probably not a byte-for-byte dump of the drive (i've tried "dd"ing it back) and there dos not seem to be any utilities out there that can reproduce the raw image of my drive out of the DMG file.

If anyone has any ideas on how to proceed, I'm (desperately) open for suggestions!
