Hard Drive Slowdown (3mb/s)

Hello, my secondary hard drive has recently begun to read/write very slowly, from about 50mb/s down to 3mb/s read rates. Thinking a defrag couldn't hurt, I went ahead and did that.. it took over 15 hours to complete. Everything was working fine until a couple weeks ago, I haven't made any changes. Could it be that some configuration variable became corrupted? Or is it more likely time to buy a new drive? Thanks for any advice..

The drive in question is a Seagate 160GB ATA
My main drive is a WD 40GB ATA
Other system specs:
Windows XP Pro SP2
AMD Athlon 64 3500+

Sometimes you can go to their website

Seagate.com's support section is 404 not found... nice.

Here's a recurring issue.

In reply to: No support page

XP degrades the DMA mode if it sees errors. Fix? Flip it to PIO and back. How? Hint: Type XP DMA into google.com and read how.

The next thing is that the motherboard drivers need a refresh. I do that all the time even if the owner insists it worked last week. XP doesn't fetch this for us so check the chipset maker's site.

Good advice, didn't work

In reply to: Here's a recurring issue.

It's looking like there's something physically wrong with the drive, so I'm now looking at replacing it. My question regarding that is.. My MB supports SATA-150, if I buy a HDD that says SATA-300 or SATA-II, will it work in my computer, albeit at a lower speed, or is it necessary to use a SATA-150 HDD? -Thanks

run the diagnostic

In reply to: Good advice, didn't work

Run SeaTools to determine if your drive is functioning properly.

SATA 300 or SATA II drives should be backwards compatible with SATA 150 motherboard controllers. To be sure, check the hard drive's documentation before purchasing. What you usually find is that the hard drive can be jumpered to force it to function as a SATA 150 device.

BTW, what is the specific model number of the Seagate hard drive?

(NT) Download it from a different computer and connection

Got seatools

In reply to: Download it from a different computer and connection

Good idea, this worked. I ran the s.m.a.r.t. test and the long test, and both show no problems.

back to your speed problem

In reply to: Got seatools

Did you try the two things that R. Proffitt mentioned?

1. XP DMA?
2. Proper/latest motherboard drivers?

I did.

DMA details

In reply to: Yes

On the IDE Channel that has the 160GB Ultra ATA (ATA/100) hard drive attached, what is the DMA mode?

Ultra DMA mode 5, Ultra DMA mode 2, other?

Here's something

In reply to: DMA details

Turns out I was looking at the wrong IDE Channel when resetting the mode to PIO and back to DMA. Now that I've figured that bit out, I see that it's stuck in PIO mode. Setting it to use PIO and then to 'DMA if available' doesn't change anything.. it stays in PIO.

Tell me about the version of motherboard driver package you installed.

same problem

In reply to: Hard Drive Slowdown (3mb/s)

Hi unfortunately i have this problem with my brand new seagate 160GB SATA drive but i've runned some benchmarks with this score: Write 3mb\s , Read 200mb\s . Its a bit frustating . I have the newest drivers and the whole computer is 1month old. I've runned the seatool and it took 4hours to complete with the result of failure of the extended test but it didnt say why... so it work properly but slow i checked the main IDE channel it is in PIO mode

drive - seagate barracuda 7200 (ST3160811AS)
Windows XP pro s2
