I'm looking to wipe an old IDE HDD I have, but I can't find a download for Gdisc so I can delete all my partitions and what not. I also don't have a floppy drive so I need to make it bootable to a CD/DVD.
Get GParted, which comes in an ISO that you can burn onto a CD with ImgBurn. Once that's done, you'll get a bootable CD which contains partition-editing and disk-formatting software.
