DOS ain't dead

MS Scandisk (Announce)

According to UI it runs the following:
Media descriptor
File allocation tables
Directory structure
File system
Free Space
Surface Scan

In virtualbox it works with 4 MB RAM, I do not know if it needs a swapfile.
On a test machine with up to 4 GB big test files it had a few problems
"One or more files on drive C are stored incorrectly and are overwriting each others data. Some of these files probably contain invalid data. To find out which files are involved, choose More Info.

1 invalid directory entry was corrected.
1 crosslink was corrected.
7 lost clusters were saved as files.

But I am not sure if this really has to say something; if I remember right I also tested an older version of edrdos which was able to create files bigger than 4 GB as it also supported a special format, i forgot the name, maybe FAT32+ (or something like this).
Speed is hard to compare, I will try to run both on a real machine.
