 Under FreeBSD 4.9 I have a system with the following:
 
 .
 .
 Waiting 15 seconds for SCSI devices to settle
 sa0 at trm0 bus 0 target 2 lun 0
 sa0: <ARCHIVE VIPER 150  21247 -005> Removable Sequential Access SCSI-CCS
 device
 sa0: 536874.496MB/s transfers
 sa1 at trm0 bus 0 target 4 lun 0
 sa1: <TANDBERG TDC 3800 =07:> Removable Sequential Access SCSI-2 device
 sa1: 3224108.528MB/s transfers
 
 The second Tandberg tapedrive works fine.  The first Archive 150MB streamer
 does not.  I can read it and copy files off of it just fine.  However, when
 writing to the drive I get the following error:
 
 nat-rtr# tar c ker*
 tar: /dev/sa0: Wrote only 0 of 10240 bytes
 tar: Error is not recoverable: exiting now
 nat-rtr#
 
 I'm guessing this is the same problem?
 
 The same drive worked under FreeBSD 2.2.8

 I have the same problem with the Archive Viper 150 reported by
 Ted Mittelstaedt: Reading works, writing fails.
 
 Running RELENG_4_10_0_RELEASE from cvs.

 O.k. I am taking back my previous feedback... on RELENG_4_10_0_RELEASE,
 I can indeed write to an ARCHIVE VIPER 150  21531 -004. (I seems the
 reason I could not previously was because the write protect on the test
 cartridge was on ;-)). However, the drives (I have 2 of them) do not
 get into proper streaming while writing: On average, they will write
 about four consecutive 32k blocks with 'dd ... bs=32k' before re-seeking.
 They seem to be streaming better while reading. It looks like a
 timing issue.
 
 But even this poor streaming might be a non-issue due to old tapes
 and/or heads. Even the temperature of the drives seems to have
 some influence.

 Well, I'm glad you're able to write. I do have an Archive 150, but I
 haven't tried it in a while.
 
 I presume that you've made sure that the blocksize is set at 512?
