The driver detected a controller error on \Device\Harddisk1
Posted on 2010-09-24
peeps, i'm having issues with our Fileserver. Basically when trying to do Backups with symantec backup exec 12.5, they're really slow and after exhaustive testing, I'm beginning to conclude it could be the hard disk as I tried with other disks and the speed seemed much better.
In the event viewer, it says The driver detected a controller error on \Device\Harddisk1. From what I see on the internet, apparently I'm supposed to go into Device manager and choose the appropriate disk and select PIO only? However, I have two Primary IDE channels and two Secondary IDE channels. How do I know which one I'm supposed to turn into PIO when I have four options?
