Possibly, but not likely. About one hour per 320gb is normal.
You might want to run Surface Scan from PW Disk tab, then create one large partition for the purpose of Checking File System on PW rightclick menu.
If you have bad sectors you should advance to the HD maker's diagnostics/Repair extended CD scan, followed by Disk Check from the Win7 DVD Command Line.

Disk Check
It could be a disk problem which is why I showed you how to run a PW Surface Scan and check File System to find out if you have issues which might need more attention.
Just because I'm curious, did you re-create the SysResv partition and mark it active for the install?
