No need to "reformat" a Time Machine drive to stop it from being a Time Machine drive. If you actually do erase it, that won't stop Time Machine from trying to fill the drive with backups. You must do this....
â Open System Preferences > Time Machine.
â Click the switch to change it to "OFF".
â Quit System Preferences.
â In a Finder window, go to the drive that was used for Time Machine, and find a directory called "Data". That's all the backups. If you hate those backups, trash that directory, and empty the trash.
As for "NORMAL USB FORMAT", two things to know:
â USB is the connection type, the hole in the side of the computer.
â format is the file system for a drive volume. For Mac using a large drive, that should be "Mac OS Extended (journaled)" and that is the way any Time Machine drive is formatted, so if you turn off Time Machine, the format is still as it should be.
The only other useful formats for 99% of home computers are....
â NTFS (used with Windows, can be read in Mac OS, but special software must be used to enable saving files to it in Mac OS).
â FAT (various versions) is only for small drives, such as thumb drives, under 64GB.

Mac Time machine???External Hard Drive?
Rob T
i have a portable external hard drive and i want to back up everything on my mac with time machine but i the external hard drive will have extra space on it after everything is done. So would i be able to use that extra free space to store stuff on IN ADDITION TO MY MACS HARD DRIVE???
thnx
my mac is 250gb and the hard drive is 320gb so even if i use all 250gb on my mac and back it up on the hard drive can i use the remaining 70gb to store other stuff?
Answer
You will need extra space because TM will periodically back up your computer. But you can partition the hard drive - use one for TM and the other for whatever you have.
Given how cheap hard drives are, why not buy a second one for the rest of your junk?
