I'm having a problem connection my Seagate 296N hard drive onto a SCSI chain. The drive works perfectly when connected by itself, and on the two Mac IIs I have tried connecting it to with internal Quantums. However when I tried to connect the drive to a Mac with a Sysquest removable <I don't remember the brand> the drive would not work at all. We tried all combinations of termination possible...My disk ended up getting garbled and needed to be reformatted. I then tried to connect it with a Macinstore. This time with some playing around we were able to get the drive to mount, but the drivers must have been corrupted pretty bad because I had to reformat again when I got home. Reinstalling the drivers didn't help. This weekend I tried again to connect the drive to the same Macinstore, this time we had partial success..The drive would mount and could be read from, but everytime we tried to copy to the drive, we would get a write error. After trying a couple times, the system eventually bombed and the drive would crash the system everytime it tried to mount it. On a hunch we tried rebuilding the desktop when it mounted and that worked, sort of. We ran Disk First Aid on it, and it said it wasn't an HFS volume! I eventually had to reformat. I've tried formatting with a couple different drivers, always with pretty well the same results. The drive is in a MacCrate box that only has 25pin connectors in and out and we thought maybe it was a grounding problem. Has anyone else had similiar bad experiences while trying to get Seagate drives working happily in SCSI chains? Any thoughts would be appreciated. Charles
