What is the difference between a quick format and a full format?

by on September 20, 2010

Q: I recently purchased 64-bit Windows 7 Ultimate. When I try to format my flash drives, quick format is checked by default. In order to full format I uncheck the quick format box. However, a full format takes several minutes. Is there any disadvantage in using quick format every time I format my flash drives?

    Quick format just clears data from the drive, the full format checks for bad sectors as well and actually writes zeros to all bits on the drive.

    For a flash drive, I’d suggest just doing the quick format.

    For hard drives, I’d suggest a quick format as well, and then use a separate tool to scan for bad sectors if needed.

    Mark, Thanks for clearing that up for me.
