RE: IBM System i guidance on disk drives not manufactured by IBM

First of all, there's a huge difference between somebody selling you a third party drive that is
supposed to be compatible with the System i and somebody selling you what they say is an IBM System i
drive, but isn't.

Secondly, I had BCC drives at a prior place of employment, and never had a problem.

They've been replaced now, but that was due to the employer not getting the response they expected
from BCC (or whatever their name is now) when trying to purchase additional drives.

Ditto. I had the same exact experience with 3rd party drives
constantly
loosing parity. I will only put IBM iSeries drives in to my iSeries
from now on.

At a former employer, we had problems with IBM non-System i drives
failing. These were purchased from a third party drive supplier, who
purchased these higher performance/higher capacity drives
from IBM and
applied their own firmware to the drives. We kept two spares on the
shelf
to handle the parity failures. We were running RAID-5, and we
never lost

data while I was there, but I believe they did have to reload before I
was
there. We got so good at swapping drives, that finally we replaced all
of
the drives with drives approved by Rochester for the System i, and we
never had another parity failure.
