when my drives failed ambient temp was around 28c for a few days and one died on hottest day in 2003.

From what I can remember two deaths on hot days, one where the drive refused to eject even after power cycle (over night off) even when in temp controlled environment. ltt showed nothing....drive replace anyway..

I think next drives I'll try are the LTO 3's which are now down below 4,500 euro in the UK (2,900 UK pounds).

Hi!

Many thanks for your reports!
It's interesting to see that those drives seem to die quite often.
I didn't expect that!

Hmmm - curious.  My notes show that our drive keeled over in May (not 10
months ago, as I said above), although it did survive the hot summer of
2003 :-)

Perhaps I should move ours into the air-conditioned room ...

May 10 WAS the summer :-)

More seriously England was thundery according to BBC, but can't find a
specific diary for Oxford......

Anyway just noticed they tended to die on hot days rather than cool
ones..not had any troubles since all in rooms where temp <25c and fairly
constant.


Just noticed that both of you guys live in England.
Now I don't know what your definition of "summer" is... ;-)

I don't think that temperature is a problem in our case.
While the office where the drive is located indeed does
not have air-condition, it's quite cool in general
(typical Viennese late 19th century building).

Anyway, in the afternoon I had a call with a HP support
guy. He asked me to have the HP "ltt" software run against
the drive to get more diagnostics. But alas it seems the
drive is not responsive anymore. Replacement time, again...

The HP support guy also told me, that the active SCSI bus
termination on the VS80e drives is very sensitive and is
one of the main reasons those drives die. Thunderstorms
and electrical induction on the SCSI bus might have negative
influence. I'm not sure if the symptoms I see support this
theory, though.
