I just replied to the original inquirer, but you have a very valid point. Maybe the drive is just getting too hot. There are some drive cooling products out there that might solve the problem. The biggest problem with them is that they seem to require the drive to be in a front-panel available slot, so you can put a fan device there. If there are other solutions, I'd like to know too. --doug

There is a fan device that attaches to the bottom of the hard drive. I have never used one, so cannot comment on how effective they are. Nevada

Not particularly helpful saying Seagate are unrelaible if that's what you
have!
Ron, checkout Seagate SeaTools. They should tell you if there's anyhing wrong
with the drive. BTW, what drives do you have, e.g. Baracuda 7,200 RPM?

To give you my 10cents, I always use Seagate SCSI drives where possible, and
so far haven't noticed any problems.
In terms of cooling, I normally go for a decent sized case, space the drives
apart, and use those front blanking plate fan things. I personally think
they're close to useless, but they're so cheap, it seams crazy not to use
them.
Kind regards,

I think that the point about the drives getting hot may be right on. The drives are Seagate 9GB 5.25" full height drives - real bricks. I used them because I got a case of 5 drives new for $100. The two Seagates are spaced next to each other because of the full height - there isn't any other room in the drive bays. I'll make sure that the case has extra cooling - I already have push - pull case fans, but perhaps I can arrange something across the drives a little better. Oh - the drives are SCSI Ultra, not Ultra-Wide, because the controller I have is Ultra, not UW. I don't think I can get a Barracuda that is not UW - I'd have to look.

I have found what maybe the problem, but I am not discounting the hardware one...
From the hdparm man page: -Z
Disable the automatic power-saving function of certain Seagate drives (ST3xxx models?), to prevent them from idling/spinning- down at inconvenient times. I doubt this is it, but it's worth a try... maybe. -- noodlez: Karol Pietrzak PGP KeyID: 0x3A1446A0

I'll take a look. These are ST410008N drives (I think that is the model number), and I don't recall them having that feature. After disassembling the case, the drive above the bottom Seagate is the one that is giving the problems, giving credence to the heat problem theory. I've removed the front panels from in front of the drives for now (I can't move them - there is no room in the bays), and will place a fan there to pull air through the case.

Hi, Just a suggestion which I have used in the past to cool drives when they are in the front of the computer. I used a normal 80mm fan and mounted it on the detachable front plates with a hole cut out to the size of the fan and a piece of mesh to keep fingers out of the fan. It was mounted so as to suck the hot air out from the drives. The only problem is the additional noise of the fan, but is sure drops the temp of the drives considerably.

Have you tried moving the drive in the cases? I had one drive that sort of did the same thing. it was caused by to much heat. the fan in the power supply went and this drive was close to it. Bought new supply and move the drive away from the power supply and it still works years later.
