take what you can get. I saw more damaged computers each week at that job than I had previously seen in my life. The manager didn't like us to replace bad caps, because that might not fix it and customers at a retail store got pissed off at even slightly high bills. The point is I have seen enough bulging capacitors now to recognise them.
I'm curious, was the bad caps issue widespread when you were in that job? Any trends you noticed in brand, year, etc? I certainly am noticing trends (like the badcaps issue did not stop in 2003) and would love to hear someone else's experiences in the field.
I have so many diagnostic programs now that I can pin-point just about anything. But nothing for RAID. Is there any RAID diagnostic out there?
If you're using the ob VIA raid then there really is no "raid controller" as we know it. As with (mostly) all ob raid, it's just some firmware bits and bios tweaks to make the system raid capable. There really is no "raid controller" to test. The "controller" is really the main CPU. So, no, you won't find any diag tools.
Now, there will be HD diag tools you can use to test just the HD's, but generally you have to somehow disable the RAID first (risky as when you re-enable, there's a question of it knowing the array is still there!), or take the drives out onto another system (1 at a time) to test.
If she isn't reporting any crashing/rebooting, and the RAID is always degrading, then the problem is almost invariably hard drives dying. Run full scan diags on them. Even with zero errors, drives can kick from arrays. I see a lot of this lately, esp with Seagate drives (what I sell most of). Perhaps the HD vendors are making their non-raid drives more raid-unfriendly to push the raid-version drives, which are now relatively exorbitantly priced? :-)
that's a new install and I'm trying to make it minimal. I have no way of knowing how long a RAID resync is supposed to take. She has 2 drives shadowed.
Good raid systems (like linux md raid) will take a LONG time to rebuild when the system is busy (so it won't bog down your system). Windows fake raid drivers sometimes make the mistake of rebuilding too fast and result in horrible interactive performance for the duration.
Before I start making nasty accusations, is it possible her mobo RAID controller isn't flushing during the Windows shutdown procedure?
Nearly impossible, though in the past I have seen some incredibly braindead VIA southbridge behavior.
