Re: hdparm
Actually, that's how I found out about the cdrom :)
I had a weird problem - my 7200rpm / ATA100 hdd couldn't read/write more than 2mb/s on Linux.
Now, after loading the VIA IDE module, and enabling DMA - It reads in 22mb/s!
I wonder how many people have the same problem and they just don't know it. (I actually worked with it that way for months, using 10% of my hdd speed).
