Hey gurus. I've been searching for answers to this problem for the last ~24 hours straight, maybe someone here will have the heart to help me please

Okay, here's the deal:
I had an '08 Toshiba Satellite with a broken screen. I pulled the hard drive from it and installed it into my new ASUS G60 thinking I could do a quick driverhunt and be on my way.
When I powered it on, I was greeted by an ATA user/master password dialog.
I certainly never set one, and nothing I've tried seems to make the dang thing disappear.
As I mentioned I've done some research and I know that an ATA password can be tied to an individual motherboard or BIOS. But for various human reasons,
I no longer have access to the original Toshiba Satellite that spawned this monstrosity (that would be an easy fix for my problem!).
I assume the password suddenly showing up when I moved the drive is some kind of vendor 'security feature,' but this is a bit ridiculous. I'm not that concerned with the drive itself, but I
need the data on it; there are many personal files that I did not have a chance to back up (I never anticipated this issue and figured I would be able to access the data from my ASUS).
Oh, and ironically enough I gave my brand-new Win7-loaded ASUS hard disk away to my family, so I'm currently typing away off an Ubuntu Live Disc :p
So here's my question: is there any way -- absolutely any way -- to fix this on my own? I'm willing to get into whatever HDD firmware utilities, manual memory registering and/or hexcode if I have to.
Or failing that, what's a reliable service who can remove an ATA password
without erasing the data?
I don't know if the drive is at High or Max security, since I'm running off Linux and all the scanning utilities seem to be win32 apps, but if that becomes important I'll find some way to check on it.
Thank you very much, folks, I hope someone has good news for me =)
Edit: The drive is a Toshiba MK1646GSX if that makes any specific difference. Thanks!
