[olug] RE: HDC: Lost Interrupt Error

Thu Apr 17 22:37:38 UTC 2003

I don't remember seeing Adam post that...?

So where would I add hdparm -d 1 /dev/hda?  Under
/etc/sysconfig/harddisk where USE_DMA = 1 is? 

Since I've changed that, it has had a few delays, but 

nothing like it was doing. 

Also, it isn't a very old hard drive, I got it in Nov
of '01. 

thanks
