I just wished to thank Steve6375 for having contributed yet another time to the everlasting confusion between disk drive (physicaldrive or disk) and
drivevolume (or logicaldrive, i.e the thing to which a drive letter is assigned) with the new twist of introducing the further confusion between file copies and sector copies (i.e. completely-unlike-clone vs. clone), and the new unit of "bit" which in the strictly technical use as in "plus a bit" surely will have a future .

Sorry if I confused you, the English use 'bit' to mean 'a small amount of something' - example: 'He replied with a bit of sarcasm'.
