Hooked PowerBook G4 to another running Mac using Firewire and held down the 'T' key on boot up. This is a Mac similar to the one http://apple.stackexchange.com/questions/34030/creating-a-backup-of-a-mac-hard-drive-that-wont-boot I connected the PowerBook G4 The non-booting drive now appears in the Disk Utility program as APPL FireWire Target Media with a partition of Macintosh HD. The partition is listed as /dev/disk1s3 I already tried fixing the issue using Disk Utility's verify and repair buttons, to no avail. Next I tried using diskutil from the Terminal which appears to do pretty much the same thing as the gui version of Disk Utility output below: PowerBook G4$ diskutil verifyVolume /dev/disk1s3 Started verify/repair volume (filesystem) on disk disk1s3 Macintosh HD Checking Journaled HFS Plus volume Checking Extents Overfile Checking Catalog file Invalid sibling link The volume Macintosh HD need to be repaired Error detected while verifying/repairing volume disk1s3 Macintosh HD: Filesystem verify or repair failed (-9957) [ + 0%..10%..20%..30%..40%..50%..60%..70%..80%..90%..100% ] Finished verify/repair volume (filesystem) on disk disk1s3 Macintosh HD Error detected while verifying/repairing volume disk1s3 Macintosh HD: Filesystem verify or repair failed (-9957) I tried using fsck_hfs /dev/disk1s3 from the Terminal, and got the following output: ** /dev/rdisk1s3 ** Checking Journaled HFS Plus Volume ** Checking Extents Overflow file. ** Checking Catalog file.

Recover a dead hard drive using dd Mar 04, '05 07:56:00AM • Contributed by: Anonymous The Unix program dd is a disk copying util that you can use at the command line in order to make a disk image. It makes a bit-by-bit copy of the drive it's copying, caring nothing about filesystem type, files, or anything else. It's a great way to workaround the need for Norton Ghost. Normally, in order to make a disk image, the disk you're copying from has to be able to spin up and talk -- in other words, it's OK to make a copy if the disk is healthy. But what happens when your disk is becoming a doorstop? As long as it continues to spin, even with physical damage on the drive, dd and Mac OS X will get you out of the fire. We had a situation recently where a friend sent a disk to us that had hard physical errors on it. It would boot in Windows, but then it would hit one of these scratch marks and just die. We fired up dd, and it started OK, but stopped at the same physical error location -- complaining about a Hard Error.So the workaround was to designate the dd mode as noerror -- which just slides over the hard stops, and to add the mode sync, which fills the image with nulls at that point. We did it on BSD Unix, but as long as you can get the hard drive attached to your Mac, the command is the same: dd bs=512 if=/dev/rXX# of=/some_dir/foo.dmg conv=noerror,sync The bs=512 designates block size, and the if=/dev/rXX# is the UNIX path to the actual disk device. Make sure that the chosen directory (some_dir) has enough room to take the entire disk image -- which will be equal to the size of the drive. Since dd doesn't care about the contents of the drive, it copies every bit on the thing, so you get an image equal to the disk's capacity. A really big file. One workaround is to put it on a RAID array. Once you've established the disk image (in this example, foo.dmg), you're almost home. Here's where your Mac OS X box is far and away the best thing to have. In this e
