No. from my experience USB will hang if the drive hit a wrong sector. I had inserted the disk in an enclosure and connected to the G4 (with new hard disk and new OS X 10.4) via Firewire cable. As there was lots of space on the new HDD, I thought why not compile ddrescue and get the image on the G4's new hard disk straight away! So I left the G4 running with ddrescue trying to read the old hard disk over the weekend. On Monday, it showed 149kB of successfully transfered data along with 30MB of erroneous data! Just as a last ditch effort before calling some data recovery service company, I thought why not give it a try on the Linux box (which was able to mount it read-only, the G4 didn't even do that!). The Linux box is reading the disk connected via USB and had finished about 9GB by the time I left without any errors. Now the only problem is that the disk is 38GB whereas I had only 32GB free on the Linux box! Need to take my external 500GB disk along tomorrow. You should: - attach the disk to an internal IDE (or sata) cable - use dd_rescue to copy the image to a file (can be long) (or gddrescue) - fsck the copied image. Do not run fsck on a failing disk, it will make thing worse. HTH The .img image(38GB) that ddrescue is creating, do I use fsck.hfsplus on it or just fsck?

The one time I thought I had a hard drive go bad and put it into another computer, it didn't get any errors on boot. I just fsck'ed it and it was fine. Turned out to be a hardware problem on the origional computer. My only experience with a laptop hard drive is on my IBM Thinkpad 600E. On that, you don't have to tear apart the unit: one screw releases a cover and you slide out the hard drive. Thinkpads, Toshibas, Dells, etc have been easy for hard disk replacement. However, Macs involve quite a few screws with weird heads to open them. This Powebook G4 had 19+12 screws!! So I've never actually needed dd_rescue so I don't know if it would be better. As long as its not worse, then just that. The important thing as I understand it is to get an image of the drive once then power off the drive. Do all your fixing on a copy of the filesystem image. Once you know what that needs, you can do it to the drive itself. Doug. I connected the old hard disk via firewire to the powerbook and compiled ddrescue to run on the G4 (new HDD and 10.4.11).

Re: OT: dying disk - data recovery recommendations
KS: I have a friend's G4(PPC) which seems to have a dying disk. He had run the Apple disk utility and it reported and error with the IDE disk. I am in exactly the same situation, currently. My approach is to use dd_rescue (package name: ddrescue) to dump the disk's content and now I am about to run testdisk on this dump to find the partition structure and any file still intact. Unfortunately, testdisk cannot write Mac partition tables itself, but I plan to use parted for that, using the values found by testdisk. If it works, I am going to run testdisk again to recover files from the partitions. It already helped me recover a friend's friend's files from an almost dead USB thumb drive, so I am quite optimistic that it will help me out again.
