We have had a small amount of problems with lto to from handling.   An 
occasional bad tape.  Operations on both sides weren't too bad, but the 
couriers were brutal.  I don't think I have the link any more but IBM does have 
doc on tape handling procedures ... ship vertical, rather then horizontal, how 
long to allow to warm, etc ...

Wanna buy some lto-1 drives and power supplies?  (3584 canisters) ?

I don't quite think an inch, but...

1.  Why LTO-1?  LTO3 is current vdersion.

2.  The cases are somewhat fragile on older LTO1 tapes.  I
think originally the two plastic halves were not "welded" together.
This led to cases where, when inserted in a drive they got stuck.
Resaon is the leader pin would get pushed slightly back when halves
of case slightly separated, and would not close back.

I have had about 6-8 failures of this type, out of about
400 LTO1 tapes I have had.  Only had one with an LTO2 tape.

I understand that by early LTO2, the halves were welded and possibly
continuing production of LTO1 tapes were also.

3.  Also, what about your onsite tape handlers too!

4.  I would suspect that in general LTO tapes are no more fragile that DLT,
unless DLT uses more durable plastic or something.

This is  a tape media question.

We are considering moving from DLT8000 to LTO-1 for offsite tape storage.

Our local IBM guys told us that LTO tapes should not be dropped more than
1/2 inch or they risk being damaged.  If you've ever watched a vault
vendor handling tapes, you know that 1/2" is pretty optimistic.

So, is that true?  Would our offsite data be at risk if our vault vendor
dropped an LTO cartridge a whole inch?

Thanks.
