I am using Mac desktops and laptops.
Instead of buying a Mac external disk, I’ve got myself an Elements SE drive.
I only had to remove the software on the disk as it invoked Windows through Parallels Desktop.
I works fine and has only the USB connection, no powersupply. So less cables to take along when traveling.
I used to have a My Book Essential 1TB drive but this got affected by x-ray during my travelings and it was impossible to replace the internal board. I was offered to send it for replacement under warranty but the value of the drive exceeded the transport cost and so I decided to dump it.
The Elements SE is much more handy and easy to take along because of its format and the absence of a power supply.
A happy customer
