1 out of 5 eggsSeagate CS said look-up "Backup"

Pros: Nice form factor. Well ventilated. An on-off switch. Bars in the front approximate storage use/left. Quiet drive and very fast. It is detachable from the base and you essentially have a hard drive that can be stored inside of your box.

Cons: Windows 7 did not recognize the drive after 10 months of use. I used the "SeaTools for Windows" to no avail. I used Acronis, no good either. Drive was still under warranty. Called Seagate Customer Service (CS) to find out what they could do. CS offered to replace the drive as it has a 3 year warranty. I simply asked for help to see if they could assist in restructuring the data or let me try to retrieve about 2TB of information and backups. Seagate CS said I would have to go to their DIY department. Their DIY department said I would have to purchase their software for about as much as I paid, during a Cyber Monday, for the drive. I asked, you mean you don't stand behind your claim and drive name "Backup Plus"? The Seagate CS lady said, I quote, "Well Sir. If you look up backup in the dictionary, it means you have your data in two places." So I guess the Seagate Backup Plus should not be one of those places. Needless to say, I will make an effort to not purchase Seagate drives again. The store I purchased the drive is my only salvation, they will provide a full refund. What good is 3 years warranty if Seagate is not willing to stand by their "backup" products.

4 out of 5 eggsGet the Firmware Update

Pros: This drive was easy to setup but needed a firmware update before it ran without issues. Since I've only had this drive a short while, I can't tell you about it's performance over time, but so far it's performing well.

Cons: So far the only disadvantage I can see to owning this drive is the short 4 foot USB cable, but that can be replaced inexpensively.

Other Thoughts: Make sure you update the firmware!! For my Mac, I grabbed the firmware update from the Seagate site, here:

When updating the firmware BE ABSOLUTELY sure that you start the update AND THEN plug in the external drive. When the external drive was already plugged in and I ran the updater, it didn't detect the drive which defaults to everything is okay, which it isn't. Once updated, you'll need to unplug the drive and plug it back in once or twice.

1 out of 5 eggsAvoid like the plague

Pros: none really

Cons: This unit is NOT as advertised.
It does NOT come with a Firewire 800 cable, and Seagate does not make one for this drive.
The product advertises that it can also be converted to Thunderbolt... but BEWARE... the adapter costs almost as much as the drive.

Other Thoughts: You should ONLY purchase this drive if you ONLY have a requirement for a USB 3.0 connection. It is totally useless for older macs with firewire ports and it is incredibly overpriced for newer macs with thunderbolt (as the adapter is insanely expensive.. in fact... newegg has even discontinued it... so you can't even get it from them)

5 out of 5 eggsBe sure to update the firmware if experiencing unmounting issues

Pros: Huge space. Got it for a great price with newegg promo. Good looking enclosure.

Cons: Until I updated the firmware, the drive had issues staying mounted during file transfer (running OS X Mountain Lion.)

Other Thoughts: Not that looks trump performance, but this is one of the best looking external drives I have owned. The black finish is smooth and ultra soft, almost feels like velvet. Wife-approved styling.

But more importantly I want to address the issue that some have reported with mounting problems under OS X. When I first plugged in the drive, it mounted and I began copying some files. Part way through the transfer, the drive unmounted and gave me an error. I tried again. Same thing. Transfer would get part way through and then unexpectedly unmount and fail.
So I downloaded a new firmware driver from Seagate, and it solved the problem completely. No more unmounting issues. The drive now works great.

The firmware update process was not super intuitive, so I want to make sure everyone knows the process (the first time I ran it, I was fooled into thinking my drive was already up to date, but it actually wasn't.)
First make sure your drive and all other external drives are disconnected.
Run the firmware updater.
The updater will tell you that no drive was detected.
Plug in your drive.
The updater will then detect your drive and give you the option to update firmware if your version is out of date.

*** When I first tried updating the firmware, I had the drive already plugged in. The updater then did not detect an eligible drive, thereby fooling me into thinking mine was already up to date.

So, run the updater, then plug in the drive.
I'm pretty tech savvy, so I'm bugged that Seagate phone support had to walk me through this, but there you have it. Their phone support was quick and helpful, by the way.

I've only had the drive a couple days, but I like it so far. I'll update down the road if any other issues come up. I considered giving it 4 eggs instead of 5, because of this issue, but since Seagate was quick and helpful, I am keeping it at 5.
