I've had a similar problem in the past with a DAT drive. It turned out to be the default density code set for the device (/dev/nrst1.1). Setting the density to 0x13 explicitly fixed the medium errors for that DAT drive. I don't thing the T2000 qualifies as a DAT, but perhaps a similar problem is occurring here. Any FreeBSD tape driver folks know if there's any truth to this? ~Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
