Re: [Networker] LTO Tapes being marked full prematurely (SDLT320 FAILURE

Hi Philip-

We have an Adic Scalar 1000 with SDLT320 drives.  We have had six drives
replaced in the span of approx 2 1/2 months.
Roughly one every two weeks.  I have been kicking myself wondering if I
steered our department toward the wrong decision (LTO2 vs. SLDT320).  I am
carefully documenting all problems in hopes of determining actual cause of
these "drive failures".

At times, looks as though its actually the barcode reader creating some of
the problems/confusion for the library.  Other times, the tapes appear to be
the cause - only at first glance.  Still other times, the drives themselves
with I/O errors.

In any case, I will try to post my findings to the group if and when I ever
get a handle on this.  It is consuming way too much of my time at the
moment.  :~|

Never thought I would miss our old tape library.

Is it me or are there quite a few people who keep having LTO-2 drive
failures???  I have an ADIC Scalar i2000 with 6 LTO-2 drives and had 1 DOA,
another failure about a week later.  Last night (almost 2 months later), I
have 2 more dead drives.

Do you think it's the ADIC library or the HP drives that are the problem (or
both)?  I'd like to know who I should be venting to before I go off on both
of them ;-)

Phil.

We had similar situation due to the tape drives malfunction.
It started slowly but in a couple weeks we had hundred tapes marked full
prematurely.
Check the event log for the drive related errors and contact the vendor to
fix or replace drives.

What brand of drives and what brand of tapes?

If they are Seagate drives, they will only work well with certain tape
brands. Maxell/Fuji/Seagate are the only ones certain to work, although
some others are Maxell or Fuji rebadged.
