So far it seems to be doing its thing. Block numbers are flying by on the terminal as it goes through the disk. So if it succeeds, what is my next step?

Wipe is similar, except it doesn't necessarily spit out a nifty list of bad sectors.
If it succeeds without listing off a bunch of bad spots, then you should be able to just pop in an Ubuntu install CD and go. Last time I tried it the installer was more than capable of formatting a completely empty disk from scratch.

Well I had a live Lucid Lynx disc on hand. Before I started the badblocks operation (which btw currently says its Reading and Comparing with different test patterns, 11 hours in), I tried to boot off the disk, but it was soooooo slow (something related to this disk was slowing it down) it came to a point where I wasn't sure if it was hung or not, so I rebooted with a USB PeppermintOS pendrive, and while it was extremely slow (like an hour) it finally booted and that's how I got back onto the forum here and got the advice about badblocks. I don't know if it would boot to the CD now or not. But now that I'm booted in an Ubuntu-based OS, what would the next step be after this finishes?
Still running badblocks...
So far after listing all the block numbers it was working on it said:
So how much longer should I expect this to go for?Code:{...} 214865% done, 4:13:57 elapsed 21487 21488 214896% done, 4:13:58 elapsed 21490 21491 214926% done, 4:13:59 elapsed 21493 214946% done, 4:14:00 elapsed 21495 21496 214976% done, 4:14:01 elapsed 21498 21499 215006% done, 4:14:02 elapsed 21501 21502 215036% done, 4:14:03 elapsed done Testing with pattern 0x55: done Reading and comparing: done Testing with pattern 0xff: done Reading and comparing: done Testing with pattern 0x00: 13.06% done, 11:05:24 elapsed

yeah i have to admit when i installed ubuntu 10.04 on my new htpc (which has an intel i930 CPU, 6 gigs ram, and an nvidia GPU) it took 20 mins for it to finally reach the desktop. It may look like it is hanging but let it sit for a while. I dont know what its doing, but eventually it will continue. That doesn't happen with previous releases of ubuntu so i'm guessing it has something to do with all the tweaks they did to make ubuntu boot faster.
I see the man page says:
So maybe that means it'll be done after testing w/ pattern 0xaa???-w
Use write-mode test. With this option, badblocks scans for bad blocks by writing some patterns (0xaa, 0x55, 0xff, 0x00) on every block of the device, reading every block and comparing the contents.
How can I tell how many blocks a hard drive has?
Well it didn't go to 0xaa but it just stopped (some 13+ hours) for 40G drive. Okay, I'll start checking it out.Code:{...} 215036% done, 4:14:03 elapsed done Testing with pattern 0x55: done Reading and comparing: done Testing with pattern 0xff: done Reading and comparing: done Testing with pattern 0x00: done Reading and comparing: done $

Hmmm... well I haven't rebooted yet, so I'm not sure if I should expect any difference, but I tried the Peppermint installer and it didn't see the disk.gparted and "Disk Utility" don't see it. I restarted gparted as gparted /dev/sda and it sort of saw it ("unallocated" 37.26 GiB), but when I tried to create a partition table to it had "error while creating partition table". Let's see... what else might I try before trying to reboot to the Lucid Lynx installer?
