I have a Seagate DDS-4 tape drive hanging off a Tekram SCSI card. I was
starting to get random hard resets whenever accessing the drive - as in
"dd if=/dev/zero of=/dev/sa0" would get me to the BIOS POST screen in
under a second - so this morning I swapped out an unused card of the
same model

You can get "ringing" on a SCSI device from bad or loose cabling which will
generate a lot of SCSI errors. There are limits to cable lengths and you
need to be sure you use proper cables for every device (and rated for the
SCSI bus speed.)
You will do best to pull out any un-necessary hardwar

Hi everyone. I'm experiencing some problems with two tape drives
attached to this machine. Here is the situation:
I first tried backing up 17GB of data using cpio to a six tape DDS-4
autoloader with a fresh 20GB/40GB Fuji tape. It stopped writing after
about 9GB and gave the following error messag

Dear all,
I am a newbies to BSD world so bare with me a moment here please.. I
inherited this freebsd 4.10-RELEASE server and i was told to install a DLT
20/40 tape drive to the server.
So, what i did was;
1. shutdown the server
2. Install the Adaptec SCSI card into the PCI slot in the server
3.

Hello,
I never had a subject in my last post, so I am posting this again, sorry.
I have recently installed a SCSI tape drive in my FBSD box:
Waiting 15 seconds for SCSI devices to settle
sa0 at sym0 bus 0 target 6 lun 0

sa0: 10.000MB/s transfers

Hi,
I'm running 4.9-STABLE on a box with an older HP 35480A DDS tape
drive. Recently the drive started spitting out any tape I insert.
It simply will not accept any tape I load. I've tried 5 different
tapes and it does the same thing. Loads, lights blink for a second
or two, and the tape is spi

Yes, I have used a cleaning cartridge... (2 of them as a matter of fact).
Also replaced all the hardware, tape drive, scsi card, and cable...
I'm not sure how to change the buffers in my back up scenario...
I know it was working for 3 years, without incident, and then
suddenly stopped, right abou
Do you have change any buffers(e.g. dump) in your backup scenario?
Do you used a clean cartridge?
