And then, it stopped. $I gingerly approached the keyboard to cd to dh0: -- it was there! $I checked out a few important directories -- all there. I did an $info -- the hard disk was as full as I had expected it to be. $Phil Mercurio $DevWare, Inc. What you had witnessed was simply the hard drive being VALIDATED by AmigaDOS. Since it was SOOOOO full, it took forever (well.. 5 minutes). This was caused by the fact that the disk bitmap probably didn't checksum correctly, and caused AmigaDOS to rebuild it. And the bitmap didn't checksum because a command had been writing to the disk when the machine crashed so badly that DOS didn't have chance to finish writing the critical information back to the drive. But, thanks to the redundancy in AmigaDOS, it is able to heal itself. Ya know, some people complain about the poor performance of AmigaDOS, but ask yourself something - have you ever lost a disk because of the DOS? In my experience it has ALWAYS been media failure, or copy protection failure. Paul Higginbottom.
