Neither is right, there are pros and cons to each. With NTFS you can have
file sizes larger than 4GB but the drive is not useable on a MAC and other
operating systems, FAT32 is supported on many different operating systems
but doesn't support file sizes greater than 4GB, the choice is yours.

Hi
I have purchased an External Hard Disk Drive, usb2 & main power, 1TB in
size.
The very limited instruction manual says it is best to run it in NTFS.

When I go to MyComputer, on the left column under "Details" it says "File
System: FAT32"
yet when I right click on the external hard disk drive letter (F) and
click "Format" it says "File System NTFS".

Which is right?
