Filesystem woes

Aaaah... I'm not sure how I should articulate what I want to say, but I guess I'll start with the following:

FUCK.

There. In a bit more detail, I guess what I mean to say is, I apparently just lost 130GB worth of data on one of my drives because of a filesystem error. I'm running Windows XP SP1 with NTFS as filesystem for that particular drive. Now, what I want to know is, is there a way to recover that stuff now? Or, actually, HOW can I recover that stuff, because I sure as hell won't take "You can't do that" as an answer.

The first clue I got that something was wrong is the message saying that, well, essentially there was an issue with the filesystem on my E: drive and which oh so helpfully told me to run chdisk. Which I did, by rebooting. And which proceeded to display the message "DELETING ORPHANED FILE INDEX (INSERT ONE OF MY PRECIOUS FILES HERE)" roughly a bazillion times. Fucker. So, yeah, that was pretty much my second clue that something was wrong. Third was the unusually high amount of free space on said drive when I checked after my computer was done booting up.

Anyway, it's a drive with mostly data on it, but some of that stuff I don't have backup for due to the space it would take, and probably won't be able to get again except with much effort, if at all. My books...

So, yeah, how do I recover that stuff? For now I'll shut my machine down in order to prevent Windows from doing a "preventive defrag" or whatever the hell it'll probably try to do. I'll check back tomorrow morning.

And I was halfway through "Surely you're joking Mr. Feynman!", and enjoying it quite a bit too.

Jam it back in, in the dark.

It seems there is no such thing as an /f option for my version of chkdsk... I did, however, attempt it with the /r option, supposed to repair stuff.

It failed miserably.

As I don't have 130GB worth or free space anywhere, that "GetDataBack for NTFS" program isn't of much use. I'll try something with partition magic, then I'll try to get a CD for WinXP SP2 and boot on that. The drive in question is a Western Digital, but unfortunately, I don't think it came with any software, so I guess I can't try that.

Any other ideas are, of course, welcome.

EDIT: Ok, so it seem partition magic sees 14% of the partition, or roughly 20GB, as "Bad". Though it doesn't seem to be possible to repair it with partition magic.

There's nowhere I can't reach.
