I get an error when running fdisk...
Unable to open /dev/hda

It worked the day before yeasterday, but now it's broke.
I've tried whatever I could think of.

Then to the second thing:
Is it possible to change the screen update rate.
I don't like having it on 60Hz. It flickers.

Thanks for your time helping a newbie on linux (installed dsl a week ago)

Niklas Ulvinge aka IDK wishes you happy programming if you're a programmer and happy times to all else.

The 60hz rate is pretty much fixed with the xvesa drivers. You would need to download and install a bigger X driver package for a different refresh rate. I think some people have been having success with Xorg, so do a search on that.

is /dev/hda mounted?

Mounting won't help, and is actually not recommended. fdisk and its relatives are run on the drive itself rather than the mountpoint, so IDK had it right. The only thing I can think of is perhaps the command was not run as root? Regular users cannot fdisk.

Yes, that's true. I was asking as a way of analyzing the problem. I'm not positive and have no way to rest it here, but I believe cfdisk will also not write to the partition that you booted from (which is a good safety feature). You would need to boot from the live CD or a pendrive, open a terminal as root and run
# cfdisk /dev/hda

Yes.and.in this case it usually notes that it can not access the drive..drive mounted
