You are not in a good state RSimpson.
If you could not read the data when the drive was slaved, you will likely need a data recovery program.
I have used
http://www.ontrack.com/easyrecovery/
with some success in the past.
You could try a CHKDSK /R in Recovery Console, it MIGHT get you some more files recovered, but it is a big maybe.
When the file system is messed with, a la Partiton Magic, if ANYTHING goes wrong there is usually nothing that can be done.
That is why Partiton Magic STRONLGLY recommends BACKING UP your data before going through with the re-partitioning.
