Using AS 6 for Win NT I can back up to this Compaq 20/40 internal drive (firmware D473) but when I attempt a restore I get a "Initiator Detected Error Recv [48,00] Log sense not supported error". This appears in my tape engine log when I turn it on to debug the problem. I was able to take the same tape to another NT machine and perform a restore OK. We do have another DEC 30/15 DLT external drive (firmware level 840B)on this same SCSI bus that is working properly with AS. Any help would be appreciated.
