We recently had problems with an APS Quantum Atlas 1.0GB external hard drive.
When we called and explained the problem to APS they immediately issued us an
RMA# and apologized. We received a brand new drive within only a few days of
sending the defective drive back. We were quite impressed with their
responsiveness.

The new drive has begun making the same sounds that our defective drive made
before it went into a constant read cycle. The sounds are that of a grinding
noise, and can be heard periodically even when the drive is not being
accessed. Are these sounds typical of APS Quantum Atlas 1.0GB drives?

We are also concerned that Quantum has discontinued manufacture of these
drives (now making only a 2.0GB and higher version). Does anyone know why that
is? Are the Quantum Atlas drives prone to problems?

Regards,
Edwin

Quantum Atlas drives have been solid performers but were legacy products
from the DEC acquisition and are several generations old in their design
(I'm not sure how that corresponds to dog years). Quantum (like most
vendors) has a roadmap for each product that includes a beginning and and
end of production. That end of life for that particular model was reached
and there is a superceding product, which likewise has an end of life
schedule. The drive does go into a periodic thermal recalc which may be
the sound you're hearing. It shouldn't make any particularly odd noise for
an extended period of time and I've asked Bob Brim of our technical
resource center to contact you to try to determine if what you are
experiencing is normal.
