Really, chkdsk on the SATA drive shouldn't have been able to hose the IDE drive install.
OK, lets try something, that I have not done before. I'm gonna try to fix the IDE's boot.ini file pointing to the SATA drive using the recovery console Currently, when you have both drives attached, and choose the SATA drive you get the following error message:

. This is implying that the SATA boot.ini line is invalid. The fact that without the IDE drive, you can boot to the SATA drive reinforces, that the SATA install is not toast. So lets try to fix it.
First, make a text file using notepad with the old working boot.ini file (found here in this thread). Feel free to add the extra switches of /noguiboot and /plextools professional. Save it on a floppy as boot.ini
With the IDE drive attached, and the SATA drive disabled boot to the recovery console on the CD.
To change the attributes of the current boot.ini file on the IDE drive. It defaults to hidden, system, read only and we want it to have none of those attributes. so we type the following:
attrib -r -s -h c:\boot.ini
Now, lets copy the boot.ini on the floppy to the IDE drive by inserting the floppy and typing:
copy a:\boot.ini c:\
Now with a little luck we have just made the SATA drive bootable with the IDE drive installed. So shutdown, reattach the SATA drive and see if you can boot to it with the IDE drive still attached. If so, now is the time to copy the my documents folder (or individual files) from the IDE drive over to the SATA drive.
