going into this review - I have to admit a certain bias - I used to only buy Quantum hard drives. I swore by them. They had some of the best stability and install software out there and I never had any trouble with a Quantum until a certain woeful day -

The Quantum hard drive division was sold to Maxtor at about the same time this drive and the 40.5 GB variant went to testing.

I bought the 20.5 GB drive for a home computer build -

It had the 7200 RPM that I came to enjoy along with the onboard 2 MB cache - so speed was top notch for it's time.

As for experience for this drive, I support some 500+ units of HP hardware out in the field that have this drive as standard equipment.

My experience is that something, and I cannot truely define what, was missed in this drive build.

I have seen more blue screens, and lock-ups of multiple operating systems and multiple applications and the only common factor appears to be this drive model.

I've seen this drive running on several different hardware platforms and on the win98se, NT4, and windows 2000 and windows 2000 server operating systems.

Early builds of this drive do appear stable. I have some 140 units with this drive in it on the east coast running 24*7*365 in a call center with no problems, but these were pilot machines and were the first released to us by a vendor. That was circa 2001 - November.

Either something changed, or the drives shipped to the central and west United States are from a different lot, as we have seen over 30% fail over less than a year and are experiencing far more blue-screens and lock-ups on this drive than on replacement drives. Replacements are either seagates, western digitals or bona fide Maxtor drives.

Side note - this issue seems to be larger than initially thought, because the vendor whom my company originally bought the machines from has "stepped to the plate" and will be replacing all the drives on close to 400 machines over the next several months. This is unusual unless the drive cannot be repaired with a firmware patch. I know the vendor and they don't typically step to the plate unless there is no other way.

I have yet to find anything on the Maxtor site about this and the old Quantum site makes no more mention of the drive division it sold off to Maxtor.

My thoughts on the subject is that this drive model was released in the middle of the merger when the Quantum drive division was absorbed by Maxtor. The remaining batch of 20.5GB and 40.5GB quantum drives are suspect at best and I cannot recommend them for use on anything but off-line storage. Definitely do not run an OS on these drives as they , at this point, cannot be rendered stable.

HP has produced a new IDE driver for the systems that were released when this drive model was in production. The ide update appears to reduce the number of errors, but does not totally appear to eliminate them. HP makes no specific mention of the drive on it's support sites and appears to have run out of their stock of this specific drive model. I'm not getting any such replacement drives at work any more.

This drive model was in wide release during the HP Vectra VL400 line which was a short lived model run for business use. Since then, the Vectra VL has moved on to the VL420 model base, and the VL400 is officially manufacturer discontinued.

My admins and techs are requesting that replacement drives not be quantums, but , at the time of this writing, prefer either seagates or bona fide Maxtor drives. We are typically getting Maxtors as warranty replacements.

My Quantum 10.5 and 15GB models appear as solid as ever, and I have every expectation I'll be using them well beyond their expected 5 year life span. As for the 20.5 fireball AS I have - it's in a stattic bag on a shelf - I'll sell it cheap if someone wants to risk it for off-line storage.

I suspect the after market on this drive will be flooded.

If you have need for off-line storage - pick these up cheap - just don't run you OS on it.

Update -

at this time the original vendor of the equipment has "assisted" in opening an HP case on these drives. We are still taking them out as they fail in the field and they are being studied by HP who then hopes to get a resolution from Maxtor - the current owner of what remains of the Quantum hard drive division. We still don't have our hard drives replaced in total, but HP is honoring their warranty for the systems. HP has expressed concerns verbally about this drive model and we are cooperating by sending example drives and serial number documentation in the hopes of pin-pointing when the line may have gone bad. The possibility of some other conflict remains and perhaps the HP analysis team, with Maxtor's assistance can come up with a solution or total drive replacement.

Thanks for the update

Update -

HP has anaylized several hard drives and has discovered that the boot sector is coming apart at the seams on these drives. They are not yet sure why it's happening only on the Quantums and have forwarded the issue to Maxtor for further analysis. The HP rep did state that they have not seen this behavior from other customers on systems with this drive.

Note that we have two or three other drive models with an exact copy of the software load that do not appear to be experiencing this issue.

That would explain why the drive appears to work fine for a secondary drive, but not as the primary OS drive on a CPU.

I'll post more as I get it - I'm especially waiting for the results from Maxtor which are anticipated in 3 weeks or less.
