Totally recommend!
||Posted .Owned for 3 weeks when reviewed.Who has time to waste on less than reliable external drives? Not me. Just like the past WD Externals that I have purchased, this one works exactly as it should. I've learned that I can expect total reliability and ease of use with WD - you can too!

Great Brand with Great Drives!
||Posted .Owned for 1.5 years when reviewed.I've used this drive with Chronosync on my Mac to backup all my Lightroom files. So far, I've had no issues, and none of my WD drives have failed so far from 2016 and onward. It could be because I have so many drives, and I do monthly backups for some drives and weekly for others. So far so good. Eventually I expect them to fail, and I just started SSD for my PS5, so hopefully this lasts me a while as well.

WD My Passport for Mac 4TB
||Posted .Owned for 1 month when reviewed.WD is the only brand I will buy or even recommend. This WD - My Passport for Mac 4TB External USB Portable Hard Drive is not as small as my normal “go-to” the WD - My Passport SSD, but in all other aspects its the same. Also, there is an alternative Ultra that’s available, but I really didn’t find that much of a difference in speed-transfer, so I opted for the non-ultra & saved a few dollars. In summary, it’s an excellent buy & even better if purchased while on-sale.

WD Passport
||Posted .Owned for 3 weeks when reviewed.I have so many of these Passports for all my machines at home. Why cause they are great and they just work. Nothing wrong with having lots of backup options. Data is so important and most people forget to back it up. Remember "he who laughs last, made a backup"

Truly Blessing!
||Posted .Owned for 5 months when reviewed.I could not be happier to own this external hard drive when I bought my new MacBook Pro with USB-C connection. All of my other external hard drives do not have the USB-C connection in handy (I am already aware that I can buy an adapter to connect those drives to my new USB-C-enabled MacBook Pro) so I thought this would be a great asset for my new laptop. And it truly is!! Am very thrilled to have extra space, especially when I have hundreds of instructional videos that I made for my deaf students!

Q: QuestionDoes this hard drive require any formatting, or can I just plug it in and turn on the time machine?
Asked by Anne.
- A:Answer I'm not using it for Time Machine, but to back up my music and video projects. I did not have to reformat the drive to do this. I use a WD Passport 2GB for my Time Machine backups and I don't recall having to format that one either.
