Frequently Asked Questions
Does the Seagate Backup Plus 4TB work with a Mac?
Yes. Install the NTFS driver for Mac that Seagate provides and the drive works interchangeably between Windows and Mac computers with no reformatting required.
Will it work if my computer only has USB 2.0 ports?
Yes. The drive supports both USB 3.0 and USB 2.0 connectivity with plug-and-play functionality, though transfers will be slower on a USB 2.0 port.
Do I actually get the full 4TB of storage?
Not quite. Seagate states that available storage capacity may vary, so usable space after formatting will be somewhat under the labeled 4TB.
