It is now dumping and I'm at 2.7 GB meanwhile. No more errors since the last one at LBA=670000 . Are these LBS identical to the block #? Maybe I'll give it another try (when this pass is through) and dump from the beginning. I'm about to get me a second identical model and maybe I then can dd the whole image including partition table so that I will not have to scan the disk for the start of the filesystems. Some time ago I wrote a little program to scan a disk for the start of a FS. Unfortunately that program is also on the crashed disk :-O -- Chris Christoph P. U.
