Yes my problem sounds weird. Maybe it has to do with Syquest because I have it with the 44 MB, 88 MB and 270 MB removable drives. It could also have to do with SCSI problems (term power, parity). But the strange thing is that one of my drives now works fine after it first had problems too.
The internal hard disks of my Mega STEs work fine and do not have this problem. I use IBM DCAS 32160 SCSI drives in my Ataris.
I will get another DCAS 32160 next week and install it into an external case. I'm interested in knowing if it will make the same trouble. If not, it is a Syquest problem.
