Easy? In Delphi? Almost impossible question!! Raise to 20000 points and wait :)
If not in delphi, try PowerQuest Partition Magic.

Putting thousands of programming hours into something like
this would be a classic case of re-inventing the wheel :-)

Use partition Magic....

If you wrote a program like this in delphi and distributed it to others
you would never ever see an end to complaints like
"I used your program and now my HD is unreadable..you @#$%^&"

hi,
there are plenty of examples around for actually getting some access using VWIN32 (note this is win9* only) but actually changing anything ... no way ;-)

search googles news archives for "delphi \\.\VWIN32" without quotes.

Here comes the solution for win9x, but use it at your own risk (!!!!!). And please don't ask me to convert that stuff to Delphi. It's surely possible, but I don't have the time for that...

Regards, Madshi.

P.S: In winNT everything is much easier, there you can just use CreateFile to open a physical drive and then ReadFile/WriteFile. You can then read the drive sectors as if it would be a normal file...
