I'm trying to install ubuntu 12.10 from DVD. Every time I try, I get an I/O error. I've tried replacing the RAM, with no change.

I decided I'd try to create a clean HD by booting into liveCD and then running Gparted. However-- gparted just runs with the "Scanning all devices" message forever-- though running fdisk -l from the terminal does find the drive fine.

Any thoughts on what's going on?

This usually happens because you have misconfigured your bios to think you have a floppy drive when you don't. Fix your bios setting.

thanks-- can you be more explicit? Which bios setting would affect this? – user101289 Jan 10 '13 at 2:02
hmm-- ok, searched the bios, indeed there was a floppy drive supposedly in the system, which I disabled. Saved bios settings and rebooted, same issue in Gparted. – user101289 Jan 10 '13 at 2:11
trying to clear the disk-- getting Input/output error during read on /dev/sda then Error fsyncing/closing /dev/sda: Input / output error – user101289 Jan 10 '13 at 2:13
@user101289, then it sounds like your hard disk is failing. Check the SMART status in the disk utility. – psusi Jan 10 '13 at 5:11
