By default, Windows will do a full format - in effect, will write zeroes all over the drive, with the intent of checking if the drive is capable of it. Unix format (newfs) will only initialize file system structures - in effect, will write out (initially empty) file tables to the drive. This takes about 5-10 seconds on 250 GB drives, so 3-5 minutes you got is way too much. There's no way of making newfs to the "checking" phase; there are separate utilities for that. > my colleague and I because there such a speed difference in formatting > things (once windows is installed) when choosing between a "Quick > Format" or > a "Full Format". Yes, Quick format will just write the file tables (this is simplified, but you'll get the picture) on Windows, too. --------------enig396E779014CCCD7FB6DCFD0D Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGDCtAldnAQVacBcgRAnNrAKCUG0SduwOwOlmx4QxIg+M9XKScPwCg+FV/ 8MNiRaqcI1ILSZmtqa87GPA= =ued3 -----END PGP SIGNATURE----- --------------enig396E779014CCCD7FB6DCFD0D--
