What you can do is set all the files on the disk (this works better from a directory down) to Full Control by Everyone. Not just All Users, but Everyone (or is it Everybody?) Click on Advanced and choose to apply this to all subfolders and files.
Well, i knew this method, and use it for my data hdd's, but not for my OS HDD's.
Recently i purchased a new 3TB drive.
The problem is that it seems no to be possible to format a 3TB drive with a small eg. 100MB FAT32 partition in order to convert it in a second step to a NTFS /NoSecurity one, and in a third step grow it to the full 3TB.
Has somebody a workaround for this?
Yes that's possible...
Launch the command line (with admin rights on win 7/vista).
If your FAT32 volume is on Z: type : convert Z: /fs:NTFS /NoSecurity
You need then to type the volume label to confirm the conversion.
Depending on the space used on the volume, the conversion can take a long time.
FAT32 has volume 2TB limitation.
It has also 4GB max file size limitation.
