Hi,

I had brought a hard disk WD blue 1T with 1-2 mb/s only on DiskBench speed test only on Windows XP SP3.

It was find when I use it on external which got 80-90 mb/s. I'd checked the dma setting was enabled on windows. Any idea for that? Any suggestion for me except reinstall the xp as I wanna to find out the root reason first.

Thanks in advance

I am not sure if I am following your question correctly.

I think you are saying your transfer rates are only 1-2 Mbps.

I would check your disk settings in your computers BIOS setup utility to make sure it is not set to PIO and is using UDMA 4 or UDMA 5.

PIO should be set to 0 for hard disks for maxinum transfer rates.

Bruce,
Thanks for your reply. I had changed the BIOS setting to PIO-0 and DMA to auto (Windows show blue screen if it set to DMA6). The result remain unchanged. Please have a look the DiskBench result as below

Is this WD hard drive a E-IDE/PATA or SATA drive?

If your drive is a E-IDE/PATA drive what type of ribbon wire are you using, the 40 or 80 conductor wire?

The 80 conductor ribbon wire gives the best results. If your drives are SATA dis-regard this information as it does not apply to SATA.

Hi Bruce, It is a SATA drive.
Any other suggestions for me? Thanks

Could you possibly test the HD with another system, using the SATA cable from the same?

Thanks for your reply.

I did test it on the same PC but boot by the other hard disk. The transfer rate was around 80-100mb/s.
So I believe this drive should be no physical problem.

Both the hard disk a clone by software. So every things should be the same except the brand and size.
When I use the said WD hard disk boot up windows and test the other hard disk. The transfer rate can up to 45-54 mb/s.

Same WD drive boot up and test by the same software "DiskBench"

So are you saying the hard disk offers 'expected' performance, when connected as a slave (second) drive and 'drops' if booted (Windows boot) from?

Do correct me if I'm wrong.

Yes, your are right.

Besides, It also has a expected performance when do test in other partition except the boot up C drive.

Thanks. Golf Lam

Useful piece of info:

Windows starts storing data on the outside of your disk, and works its way towards the center. That way, your files will be as fast as possible. The fact that the performance drops by 65% from the outside to the inside of the disk helps illustrate that disk performance is WAY better for files stored on the outside of the disk. It also shows one big reason why, as your disk fills up, it also slows down.

transfer rate depends on the track location, so it will be higher for data on the outer tracks (where there are more data sectors) and lower toward the inner tracks (where there are fewer data sectors)

^ I'm guessing the Windows installation runs off the inner track. However, that doesn't address your problem.

nsufficient memory, improper page file settings, and a lack of available free hard disk space will cause excessive paging and slow performance.

^ Have you checked your Windows 'page file' settings?

To Change the Size of the Virtual Memory Paging File
You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.

* Click Start, click Control Panel, click Performance and Maintenance, and then click System.
* Click the Advanced tab, and then click Settings under Performance.
* Click the Advanced tab, and then click Change under Virtual memory.
* Under Drive [Volume Label], click the drive that contains the paging file you want to change.
Under Paging file size for selected drive, click Custom size, type a new paging file size in megabytes (MB) in the Initial size (MB) or Maximum size (MB) box, and then click Set.
If you decrease the size of either the initial or maximum paging file settings, you must restart your computer to see the effects of those changes. When you increase the paging file size, you typically do not need to restart your computer.

To have Windows choose the best paging file size, click System managed size. The recommended minimum size is equivalent to 1.5 times the amount of RAM on your system, and 3 times that figure for the maximum size. Example, if you have 256 MB of RAM, the minimum size would be 384, the maximum size would be 1152.

For best performance, do not set the initial size to less than the minimum recommended size under Total paging file size for all drives. The recommended size is equivalent to 1.5 times the amount of RAM on your system. Usually, you should leave the paging file at its recommended size, although you might increase its size if you routinely use programs that require a lot of memory.


My next suggestion would be to defragment the C: drive and check the transfer speed.
But first, try restarting your PC in the Windows Safe mode and check the results using Disk Bench or HD Tune.

Sorry, kinda stumped over this...

It seems fix my problem at the moment. I will do another test on it and get back to you.
