Check your SCSI bus, make sure the cables aren't too long, and it should work fine again. If it doesn't, let's hear more details on your SCSI subsystem. Host adapter? Other devices? FWIW, I've been using a DLT4000 for about 6 months now. I've seen the problems you describe, but I got rid of them by changing the configuration (which includes a CD-ROM changer, 3 tape drives and 2 disks).
