Sounds like this is more like a hardware-related stability issue then. The drive itself sounds suspicious, but some motherboard power problems could also cause your symptoms.
First, check and see if any of the capacitors on your motherboard are visibly bad (See *Note below). There was a specific, known problem that affected many motherboards a while back (deatiled on Carey Holtzman's link below), but even the best capacitors of this type in *any* motherboard are subject to failure - just not as frequently.
Some things to note about this information:
1) Electrolytic capacitors do not have to be visibly leaking or puffed out to be fried. This is only a quick and cheap inspection to see if any are *visibly* bad. Nice-looking ones may be shot as well, but testing requires special knowledge and equipment.
2) Nothing should ever be leaking out of a good capacitor. They put pictures of obviously leaking ones on the web page for illustration. If you have the tiniest dot of dried brown liquid anywhere on the silver top of a capacitor, it's already fried.
3) The lines that intersect on the silver top are meant to crack first in the event of an overheating, ready-to-explode cap. Most don't ever get to this point - they only develop a little pressure inside before they fail and may never leak. A new cap will be perfectly flat or maybe almost look a little concave on the top. If there's *any* detectable 'doming' or puffing out of the cap, it's bad.
*Note: Don't stress out too much if you're not sure about any of this. The point is to not waste time on other troubleshooting if there's an *obvious* problem with the motherboard. If you're not sure, don't worry about it for now and press on.
Next, it probably makes sense to check the drive itself out for problems.
If it's an IBM DTLA drive (DeskStar, but might have some kind of HP label on it), check if you need the firmware upgrade with this HP utility (creates boot diskette):
ftp://ftp.hp.com/pub/ccd/soar2sdd/vc1498/vc1498en/vdg510en.exe
It won't hurt anything if it's *not* an IBM drive or it doesn't need the upgrade - the utility just checks the firmware revision number. Do it if you're not sure, but don't bother if it's obviously not an IBM drive. After that (IBM drive only) run IBM's diagnostics. Info at:
Also creates a boot diskette. Actual file to download:
(Anybody reading this with the problematic drives from the DeskStar line can/should use this utility regularly)
If it's a Maxtor drive instead, you can use:
to crate a boot diskette with diagnostics. Most of these "make a boot" floppy utilities have to be run in Windows. Convenient when you can't load Windows and want to diagnose a problem, right?
If it's not either of those brands, then respond with the manufacturer or model/part number. I just suggested IBM and Maxtor first because HP used a lot of them in that line and both had lots of problems.
You generally want to use the manufacturer's utility to do the diagnostics. HP has some capability in their diagnostic utility, but (like most other OEM tools) it's kind of a dumbed-down version.
Let us know what you find.
