Re: LTO4 drive with possible issues

Another thing I forgot to ask on LTO tapes:

4) Doing a little reading on LTO tapes and I found on Wikipedia (which is
never wrong <g>) "LTO uses an automatic verify-after-write technology to
immediately check the data as it is being written, but some backup systems
explicitly perform a completely separate tape reading operation to verify
the tape was written correctly. This separate verify operation doubles the
number of end-to-end passes for each scheduled backup, and reduces the tape
life by half." We do verifies via the backup software. Should I forget
that?

All,

We're having some tape issues with our Windows servers backups to LTO4
tape. We're trying to figure out if the issue is some of the tapes or the
drive.

Questions:

1) If I find someone else locally that has an LTO4 drive for Windows
backup, the tape should be compatible with that drive, correct?

2) If I find someone else locally that has an LTO4 drive for IBM i, the
tape would *not* be compatible with that drive, correct?

3) The backup software (Nova) has a Format option that I use to name new
tapes. Since that takes a matter of seconds, it's really just naming it
and doing some quick format to say "I'm an empty tape". Is there such a
thing as a true formatting of an LTO tape after it leaves the factory?

Thanks.
