Yep, it's checked by default of course.
I've done some further testing on this and R-Wipe 9.6 definitely does not fully wipe out the MFT table on Windows 7 Home Premium 64-bit for AHCI SATA drives 1TB and higher. I got worried about this having trusted R-Wipe for many many years and sunk in the last few days testing before I let these two PCs go that I sold on Craigslist. I am seeing that there's always plain text unscrambled filenames left behind after free space wipes for any files that were deleted outside of R-Wipe (stuff like uninstalls or just deleting a folder via windows explorer or emptying the recyle bin normally). The expectation though is a free space wipe will zap all of these.
I've tried a 1TB and a 1.5TB drive (both rently purchased Seagate Barracuda 7200s) with the same results as the 1TB Seagates in the PCs being sold. Install Windows 7 and some various programs, do some work with them to generate some data. Do some uninstalls, go in and manually delete some data folders using Windows Explorer. Defrag the drive, Chkdsk /f the drive, R-Wipe the free space (using either psuedo random or DoD 3 pass doesn't matter), reboot. Should be pristine. But check the drive with R-Undelete detailed scan and there are *many* of the deleted filenames uncovered plain as day. Folder names are gone, file contents are unrecoverable - but many filenames persist unaltered complete with their original file extensions. Granted they are not 100% all found but the above steps still netted me 182 filenames in only 20 minutes of detailed scanning with R-Undelete. All it takes is one filename with a name or address in it though and you're now know to a stranger. Not cool at all.
