Finding out if my HD 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

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:

Ultra ATA/133 PCI Adapter Card
