Why do you think you have to use Java for this? – user207421 Jun 06 '12 at 15:47 — user207421, Jun 06 '12 at 15:47

Run native command line utilty of OS you are using. For example format c: on Windows :)

Use either Runtime.getRuntime().exec() or ProcessBuilder for this. Disk formating is a responsibility of file system that strongly depends on platform. Java is a cross-platform and I doubt it has (and even can or should have) such built-in functionality unless somebody already created library that wraps platform specific calls I mentioned and provides pure java API.

ok Alex..Can yuo please give me small sample code? – Jayant Varshney Jun 06 '12 at 13:05 — Jayant Varshney, Jun 06 '12 at 13:05

you can not format directly. You will need to invoke a operating system specific program to do the actual work for you. check this link this might help you

+1 Under unix, as root, you can read/write the raw disk. If you know the exact format for an NTFS drive it could be done in theory, but it would take an obscene amount of effort. – Peter Lawrey Jun 06 '12 at 09:25
