Slow Spin Up Times
Posted 05 June 2004 - 11:12 PM
Recently both hard drives (made by Maxtor) in my system are suffering by slow spin up times (i.e. the BIOS doesn't detect them in the time they're given). This only happens on some startups; when they don't start up you can hear a high pitched whine. At first I thought it was the hard drives so I replaced the hard drives; the drives seem to work fine on other computers, and other drives givet he same problem on my comp.
This means its either my PSU or motherboard or something right?
I'm using an Antec TruePower 430W, and an Asus P4T533-C motherboard. I've tried taking off a few devices but it still gives the problem. The spin up time in SMART has gone down to 173 for one drive and 169 for another. Any ideas?

1. Unplug your ATA cables from the drives and just keep the molex power plugged in. Does the problem persist when you turn on the system?
If the drives spin up fine without the data cable, then you know its either the ATA cable or the motherboard
2. Try a different power cable from your PSU (although that's a long shot, but anyway, just to check)
If the drives work fine, then you know its the PSU (Antec has a two year warranty, so get it replaced ASAP, since your whole system is at risk this way)
hope this helps,

I've tried 1. and yes they still sometimes do not spin up.
2. I really am guessing its the PSU because the PSU before gave the same problem (at first I thought it was the HDD).. The Antec is the TruePower 430W and from the use of a power calculator online (can't remember the link) my estimated power summed up to quite close to 430 so maybe a larger wattage PSU might fix the problem (darnit Antecs are expensive! and mine is just about a month old).. I notice how ever since I added a HardCano 12 (ThermalTake) in the hard drives don't always spin up. Also, my 700VA APC SmartUPS reports an increased usage from 33% to 37% (maybe that's triggered it)...

I noticed one thing; You guys know how the Radeon 9700 (and almost all new ATI cards) ship with a molex splitter that provides additional power to the 9700? I found out that the - (yellow) wire was loose and every time i touched it it sparked and the whole system froze/restarted. Once I removed that everything seems a lot smoother; the drives can spin up properly almost every time except sometimes they can't find the boot sector.

But...I don't see enough internal hardware to max out even a 350W PSU...I'm not comfortable at all with your system crashing/freezing many times when you touched that yellow wire...I don't know which components you may have fried...
The only thing left to try is plugging in your two hard drives into another system to check if they find the bootsector every time. If not, then the drives are fried. If the drivres are fine in the other machine, then try another PSU to see if that solves the problem. Apart from that there's not much else...

Every piece of hardware seems intact.. Everything is running A.O.K. without that piece of wire so I'm guessing it was really that.
The hard drives all work fine on different systems and previously before the culprit was identified, drives that are fine on other computers give the same problem if they're placed here.
