Two ideas:
Run the write zeroes application within your drive manufacturer's disk utility as I mentioned earlier in this thread.
If you don't want to write zeroes, but do want to get rid of that 100 MB hidden system reserved partition and do a full format, you can reinstall Windows 7 in this manner:
1. Once Windows 7 Setup is loaded, press Shift + F10 keys at the first setup screen (which allows selection of language, keyboard and locale). A Command Prompt window will be opened.
2. Run Diskpart, the built-in disk partitioning tool of Windows 7 with the following command:
diskpart
3. Type in the following commands one by one, followed by the Enter key; (text in parentheses are comments only):
list disk (to show the ID numbers of the hard disks available, in a one disk system you should see only Disk 0)
select disk 0 (change 0 to another number if installing on some other disk)
clean (this deletes all partitions on the selected disk)
create partition primary (creates one new partition covering the entire selected disk; create others later in Windows if needed)
select partition 1 (chooses the partition you just made)
active (makes that partition active)
format fs=ntfs (full formats the partition)
exit (dumps you back into the Windows 7 install where you continue as usual)
