Finding out if my hard disk is UDMA 100 or 133?

[Simon Harvey]

Hi everyone,

Does anyone know how I can find out if my hard disk is UDMA 100 or 133 via
the operating system?

And if anyone happens to know off the top of their heads, what would happen
if I put a 133 in a motherboard that only supported 100? Would it work at
the slower speed, or just explode? Is it a good idea even if it did work?

I'm hoping the is some utility in WinXP that will tell me what type of drive
I have. I cant be arsed taking my computer apart because its an awkward one
meaning that I've got destroy the whole case just to get to the one remaing
screw that holds the drive in place!

Thanks to anyone who can help

Simon

You can go into your motherboards bios and you should be able to see the
model numbers. Or you can right click on your drive in My Computer and
select Properties and under the Hardware tab you should be able to see the
model number and look that up on the manufacturers website. You can also
download and run Aida32 from:
http://www.aida32.hu/aida32-download.php it will tell you the model numbers
and the speeds they are running at. A 133 installed in a motherboard that
only supports 100 will just run slower.

Download AIDA32 - Personal System Information
http://www.aida32.hu/aida32-download.php

After installing this program, click on:
Storage > ATA and look at "Max UDMA Transfer Mode".

An ATA-133 hard drive will work fine on a motherboard
that supports ATA-100 drives. If you wish, you can purchase
an ATA-133 PCI controller card that will provide 133MB/sec
transfer rates. Example:

If you have standard drivers, go to Control Panel - System - Hardware -
Device Manager
and look in IDE ATA/ATAPI disk controllers, and d-click Primary or
secondary channel as needed. On the Advanced page it should tell you
the UDMA transfer mode in use ( 4 for 100; 5 for 133).

If you have other drivers then they will have their own methods - eg if
you have the Intel Application accelerator installed it has its program
in Start - All Programs

If the controller only supports 100, then a 133 drive will run at that
lower speed (the difference makes very little practical effect).
