Well, the plastic wrapping on this DDS-1 tape tells me of 3 versions of the DDS-1 tapes, 60, 90 and 120m, equals 1, 2 and 4 GB respectivly. > Humm, I must have forgotten the increments on the DDS family. > That doesn't translate to half the capacity per meter of a DDS2, > which is 4gb before compression.

I did once, but maybe I got some strange results, see below for my previous mail to the list about the tapetype.. well.. since I'm going to work now, I just started the tapetype util again, this time with /dev/nst0 instead of /dev/st0: ./tapetype -e 2g -t "HP 90 meter DDS-1 Data Cartridge" -f /dev Probably have a result when I get home. /Christopher ----- Original Message ----- From: "Jon LaBadie" <[EMAIL PROTECTED]> To: "Joffer" <[EMAIL PROTECTED]> Sent: Friday, November 29, 2002 5:20 AM Subject: Re: Tapetype - 90m DDS-1? > On Fri, Nov 29, 2002 at 01:24:03AM +0100, Joffer wrote: > > I haven't been able to find a tapetype for my DDS-1 streamer.. > > > > I compiled the 'tapetype' program and started it as shown below: > > > > root@budbringeren ~/filer/amanda-2.4.3/tape-src# ./tapetype -e 2g -t "HP 90 meter DDS-1 Data Cartridge" -f /dev/st0 > > wrote 13100 32Kb blocks in 20 files > > wrote 16375 32Kb blocks in 25 files' > > wrote 19650 32Kb blocks in 30 files > > wrote 60260 32Kb blocks in 92 files in 10872 seconds (short write) > > tapetype: could not write any data in this pass: short write > > root@budbringeren ~/filer/amanda-2.4.3/tape-src# > > > > This mean anything? > > I think tapetype expects the "norewind" device.
