Do I need to install any software?
No. It is plug-and-play — connect it over USB and the drive appears ready for drag-and-drop file copying, with no apps to install.
Does it work with Mac?
It ships ready for Windows. For full read and write on macOS or for Time Machine, reformat it to exFAT or APFS using Disk Utility.

It is an included data recovery service that helps retrieve your files if the drive is damaged or fails, adding peace of mind to your backups.
Singular Expert Insight
The Expansion Portable is Seagate's value everyday drive: a simple, bus-powered way to add 1TB of storage, with the bundled Rescue service as a welcome extra. It is a mechanical drive, so if you regularly move very large files or want faster transfers, a portable SSD is the upgrade; for affordable everyday capacity on the move, though, this portable hard drive is hard to beat.

Buyer's Guide

Buy it if
You want simple, affordable 1TB portable storage for backups and files, with bus-powered plug-and-play convenience and Rescue services.
Skip it if
You need SSD speed, rugged protection, or built-in backup software and encryption — this is a basic mechanical portable HDD.
Also consider
The Seagate One Touch for backup software, a portable SSD for speed, or a higher-capacity Expansion if you need more than 1TB.
