I have heard by doing so it limits file uploads per time to 4GB?Time Machine requires the Mac OS Extended (Journaled) format. Just attach the drive and open Disk Util and select the drive on the left then go to the erase tab and select Mac OS Extended (Journaled) ion the drop down then click erase and you will be all set to use the drive with Time Machine.
NTFS is only if you need to use the drive in Windows.
No... if you format the drive to HFS+ to use form Time Machine, it won't work in Windows by default, but you can buy software like this that would allow read/write with Windows and HFS+.Ah ok I see. Will this maintain read/write capability on Windows machines as well?
