may i know how to format thumb drive using apple?? when i right click i cant seemt o find the command

Try Disk Utility as it will list all mounted drives.

Disk Ultility will be the one.
At disk ultility select your drive, use erase function, done.

hmmm... thx

Disk Ultility , just make sure to select FAT/MS-DOS and not HFS+/UNIX , otherwise Windows would not detect it [But if you plug the Pen Drive to a Linux Box ,it would detect it and mount it as well]

Better to format your thumbdrive to a Windows format. Macs will recognize it as well as PCs. That way your thumbdrive will be compatible when you want to transfer files (eg MS Office files) across to a PC. You can use Disk Utility to format to a Windows format too.

One thing to note that if you format the thumbdrive to Windows/MSDOS format, transfer rates will be slower.

The price you pay for compatibility. Hmmph!
