Installation was easy. The drive has a 4-pin hard drive power connector and a USB "B" connector. The internal USB cable runs to one row of a standard motherboard USB connector (a 5x2 block with one pin removed). If I'd opted for the bare model it would have been inconvenient, as I wouldn't have had the necessary internal USB cable.
Ubuntu 8.04 Hardy Heron detected the drive right away. /proc/scsi/scsi says:
Host: scsi2 Channel: 00 Id: 00 Lun: 00 Vendor: QUANTUM Model: DAT DAT160-000 Rev: WU82 Type: Sequential-Access ANSI SCSI revision: 03though interestingly /proc/scsi/usb-storage/2 says:
Host scsi2: usb-storage Vendor: Hewlett Packard Product: DAT160 USB Tape Serial Number: 4xxxxxxxxxxxxxx6 Protocol: Transparent SCSI Transport: Bulk Quirks:(specifically, check out the value of 'vendor')
I ran a dump and a restore to a piece of DLT160 media with tape compression turned off (mt compression off). Dump reported "throughput 5865 kBytes/sec" which is a bit below the claimed 6.9MB/sec but also about 10% faster than my old DLT. Restore ran without a hitch.
I still haven't tried a DLT72 media, and I'm particularly interested in figuring out how to check the media type from my dump scripts--since there's a 3:1 price difference between DLT160 and DLT72, I will be using a mix of the sizes.
(just a side note: on Ubuntu, it's very helpful to export
TAPE=/dev/nst0, because somebody decided that
all tape devices should be under the directory /dev/tape, in
contravention of a billion seconds of unix tradition)
