They work if I disklabel -e -r but rarely if I disklabel -w -r. I tried changing the geometry in the disklabel from that reported by the SCSI probe to 64 heads / 33 blocks per track as suggested by one person. (Apparently that is the geometry the controller uses.) - I still get corrupted data when reading or writing to the Quantum P105S. The filesystem still gets trashed. - I started trying out my Quantum PD210S. I can disklabel it but cannot newfs it. I get the following message: write error: 411647 wtfs: Invalid argument followed by a console message saying: sd1: illegal request 411647 is the last block in my `a' partition of sd1. Both disks work fine under MS-DOG. Since the tape drive works, I'm more suspicious that *I* am doing something wrong or there is something wierd interaction between the 1542C and the Quantum drives. Any insights? Thanks to all who replied to my first plea for help. -john -- === jfieber@sophia.smith.edu ================================================ ======================================= Come up and be a kite! --K.
