hdparm inop now?
 

I was following instructions tuning my hard drive using hdparm on RH 8.0 to tweak performance and now the hdparm command will only give me "input/output error" after I ran the command:

hdparm -X66 -u1 -m16 -c3 /dev/hda

The system did not hang, but performance on the drive was slowed to a crawl when I checked:

hdparm -t -T /dev/hda

so I rebooted the system to reset it, and now the only thing I get from hdparm, in any form is "input/output error"

In addition, hdparm man pages now cannot be found, where before I could access them.

Any ideas?

X seems to run fine, and the system seems to run okay still.

My system:

ASUS A7N266-VM
AMD XP 1700+
WD 136 AA
512 Meg memory
dual boot with WinDoze 98
