are you running Fat32 or NTFS on your FW Drive?
NTFS
... this tip comes probably too late, but grab yourself a copy of partition magic. If WinXP corrupts a partition (ie. is appears as 'unknown' or 'unallocated'), 90% of the time you can recover it with PMagic.
I downloaded the evaluation copy of GetDataBack NTFS and it has been able to read the data on the drive. The MFT is corrupt, so the root directory tree has a lot of garbage in it, but I can still find many if not all of the folders and find nearly all of the files I have been worried about losing.
The evaluation copy doesn't let you COPY files (I have to register it for that much needed function)...but it lets me open files in their native apps (so I can still save them out on my good drive). This has already allowed me to rescue many things without even paying a dime!
BTW, what do you think of Premiere Pro compared to Pro?
I assume you mean compared to 6.5? My thoughts are that Pro is not ready for prime time. If I had realized it was a major rewrite, I may have waited until version 2.
PROS: Pro's definitely faster at scrubbing through DV video, the draft mode previews transitions and effects better than the real-time preview of 6.5, I like attaching transitions to clips rather than a transition track (especially because it allows you to use transitions on titles and other composited elements), I'm thrilled that it reverses field dominance by shifting rather than swapping fields, less crashes when bringing up the titler, better keyframing, and, FINALLY, the full resolution of images can be preserved so I can scale all the way into them (I wish I still had the source footage from the last Prime Canyon Drive since I pushed in on several photos...the one of the cake got especially blurry).
CONS: Pro's playback to DV device seems to less solid (I use 6.5 in the rare instances I need to go back to DV tape to avoid drop outs)...not to mention the blue screen error I get when I turn on my DVcam after Premiere Pro is launched, Pro's Adobe Media Encoder behaves oddly when not using DV resolutions, gradient wipe transitions (my fave) are busted, MPEG editing still not reliable (microMV support questionable), conforming audio (as you mentioned) is a pain, what happened to the always de-interlace when dropping below 100% speed option?, and I'm pissed that you have to pay extra after three 5.1 AC3 encoding sessions.
