It sure *sounds* like you accidentally did your install to the old
disk instead of the new one. If that is the case, then your old data
are indeed lost -- overwritten with the new install.
Also, it sounds like you were following the advice for moving your
whole system to the new disk, whereas the advice for *adding* the new
disk to the old one would have been more appropriate. That's the
"disk formatting tutorial" article in the documentation collection.
