This has probably been asked before, but I can't find the answer, and I have limited time to find the answer. I can't figure out how to access my hard drive's files. I keep trying to mount the Hard Drive (HDA1), but it gives me this error:

Unable to mount device
Error org.freedesktop.Hal.Device.Volume.UnknownFailure

I will probably need to use this bootable CD on some other computers also, but I don't have access to those computers yet. I don't know if there is something I am doing wrong, or maybe it's just my computer. My computer boots up just fine, but I can't access the drive from Knoppix. I am using the latest stable version of knoppix.

Is there something I should type in Terminal Emulator ? Thanks
