Dear List,
I have labeled a fresh tape which runs fine for now. But after a
while it stops working with the error quoted below:
<error>

At this point I thought "DDS tape for sure!"
so probably tape-error thn hardware error?!

THis is a DDS3-tape
:-)
with hardware-compression turned on, so 7 GB of
data should not be the end of the tape. Is this behavouir hardware
or software related?
Currently I have no physical access to the drive to see if the
cleaning tape should be used, indicated by a red light.
You can use the tapeinfo program to report the drive's status, and
with any drive from the last few years (say, since about 1996 :-)
that should give you the proper status. "Tape Alert" is the keyword
you're looking for.
OK, thank you. And what is the next step when tape-alert is found?
tapeinfo "translates" the SCSI tapealert status, i.e. it prints what the
drive thinks is its staus in text, like the following from tapeinfo.c:
" Clean Now: The tape drive neads cleaning NOW", /* 0x14 */
"Clean Periodic:The tape drive needs to be cleaned at next opportunity", /*
0x15 */
"Cleaning Media:Cannot clean because cleaning cartridge used up, insert new
cleaning cartridge to clean the drive", /* 0x16 */
More details can be found at the pdf at
http://www.t10.org/ftp/t10/document.02/02-142r0.pdf which describes the
current (?) tapealert standard.
Any ideas are helpful.
Replace the cartridge. Clean the drive. Hold your thumbs :-)
I did that 1 week ago. Why do I need to clean the drive that often? I
should think about buying more reliable hardware...
Yes. Worked wonders for me.
In fact, with a limited budget I found that a used DLT system is more
reliable than a new DDS one... of course, I didn't try that dozens of
times, but until now this was always the right choice.
Need an offer? :-)
Use eBay ;-)
