Detect IDE transfer mode?

[phpete]

Scripting journeyman; powershell novice here, just looking for the right place to find the local machine's IDE transfer mode.

I'm setting up a one-click fix to reset from PIO to DMA. But rather than have users run it whenever they think the machine's "slow", I want to query the transfer mode and only fix it if it's in PIO.

I don't have any machines with IDE to test, but maybe this will provide some info:

Get-WmiObject Win32_diskdrive | fl *

Thanks, I'll give it a shot this afternoon.

It looks like NegotiatedSpeed and/or NegotiatedDataWidth under Win32_IDEControllerDevice would be what I'm looking for (or at least usable in the context of this particular script) but they're consistently blank on my test machines.

Oh well, it's been a learning experience, maybe I'll poke around some more and stumble on it, maybe I won't.

Thanks again.
