I run my Quantums continuously, both at home on the 3000 and at work on SPARCstations. The ones at home have been continuously powered on since mid May, and the ones at work have been continuously powered on since about mid '89. I have run a Maxtor, several Fujis, Micropolis, Seagate for extended periods, with only occasional problems, usually fixable. Disks are like that. Sooner or later all hard drives will fail in one way or another. When it happens is a matter of statistical probability, the way the drive is treated, and the quality _of the individual components_ in each drive. Good Things To Check: airflow and cooling, real reason for the problems (possibly errant programs, spurious resets, etc.), power supply voltages. -larry -- It is not possible to both understand and appreciate Intel CPUs. -D.Wolfskill +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+

[] Any netters out there have data about the reliability of Quantum hard drives? I remember somebody recently posted an article about the integrity of the disk surface of drives made by various manufacturers. I think the poster said that the Quantum drive tested was average, but not exceptionally clean after extended use for some period. I'm concerned about this because my Q40S started acting flaky this week (1 year + 3 weeks after purchase)! If I leave my A2000b powered up for too long (>10 hrs), I'm bound to get a read/write error. This worries me because I have an A3000/25-50 on order, and I'm afraid that within a year (I expect to be using it constantly), I will need a new HD! If Quantum drives aren't meant to be used for extended periods of time (days or weeks without power down), then I'd rather sell the Q50S while it's new and get something more durable. If you have real info about the reliability of various HDs, please post! If you want to offer an opinion, please send me mail. Thanks for all info/opinions/experiences! Marcel A.

I remember somebody recently posted an article about the integrity >of the disk surface of drives made by various manufactures. > [stuff deleted about 40Q probs] I've been running a Quantum 105Q 24 hours a day for about nine months now with no problems. I've also had 80S's and 40Q's running in various Amigas for almost two years with no ill effects. In my experience, Quantum drives are very reliable. I have seen a few bad ones come out of the box, but VERY few failures. -Chuck -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Chuck Joslin Commodore-Amiga Education Market Specialist AmiComp Computer Center Orlando, Florida (407)366-2000 BBS (407)366-6336 Only Amiga!
