SDCopy: Error retrieving HFS meta data ... type: 8\n: Input/output error

[yokimbo]

I'm having issues backing up an external drive. I searched the forums and the web with no luck, so I'm posting here hoping for some sage advice. Please help if you can.

** DETAILS **

OS: OS X 10.5.4

External HDD (SpecialSauce): WD5000E032 - Western Digital 500GB My Book Pro Edition

SuperDuper! log (this attempt was to an identical model drive): Sept 1st

After the above failure, which was my second, I ran Disk Warrior to rebuild the directory and check the files and folders of HDD SpecialSauce. Everything checked out fine.

After this I made another attempt on a brand new WD5000H1Q (Western Digital 500GB My Book Studio Edition). I received a similar failure, this time on a different file. I ran a Dsk Utility Verify Disk command. It passed. I re-ran the Disk Warrior file & folders check. It passed that too.

The next test I think I'll try is to just do a copy/paste. Also looking into cpio command. Any help would be greatly appreciated.

Thanks.
