Your Seagate Expansion External Hard Drive Now Comes ExFAT Formatted

And this means you can plug straight into your Mac and use.

Previous versions of this drive were NTFS formatted. And you’ll still find them for sale.

What’s that?

NTFS is a file system a Windows PC uses.

Your Mac can read an NTFS drive. But when you want to put your files on there. It’ll appear like it’s somehow blocked.

To use fully on your Mac you needed to reformat first.

You could take the 5 minutes or less and format your Expansion Portable for your Mac

But now the latest drives come ExFAT formatted.

You can copy and paste. Or drag and drop your files straight onto your drive.

ExFAT is compatible with Mac and Windows. And this means you can share your drive.

But you can’t use ExFAT for a Time Machine backup on your Mac. For that you’ll have to format. You can find out how, in this article here on the site. ‘Seagate Expansion On Mac‘.

Your Seagate Expansion Is A USB Powered Portable Drive

What does that mean?

Your Mac powers your Seagate external hard drive.

Which means you’ll only need one cable for both power and data transfer!

Just the simple convenience of using it on your Mac without outlets nearby.

Imagine yourself abroad.

All you have to do is find a power adapter for your MacBook.

Plug in your expansion and expand the storage of your Mac’s internal drive.

Is your Mac a pre late 2016 Mac model?

Then your Seagate Expansion Portable will plug straight in.

If your MacBook Pro, MacBook Air or iMac model dates after that. It’ll have a USB C port.

The great thing about the USB standard is that it’s backwards compatible.

Your new Mac with USB C ports will send your files to your Seagate Expansion Portable at USB 3.0 speed.

You just order yourself an USB C to MicroB cable. OR A USB C to USB type A adaptor cable and plug right in.
