Question 1

Does this work with USB 2?

Accepted Answer

Yes all USB devices are backwards compatible with previous versions. So this will work with USB 2.0 and USB 1.0. It will just not be as fast. I have myself used it with USB 3.0 and 2.0.

Question 2

Is this compatible with a Thinkpad R61 running XP?

Accepted Answer

This does work with XP, Remember XP does not support drives over 2TB.
This version is the USB 3.0 at 5GB a sec.
If your thinkpad doesn't support 3.0 then get the 2.0 ver. its cheaper.
I have 8 of these for my Tower PC using a 2 or 1 TB internal hard drive in each one. 
I hope this helps.

Question 3

Is this device Mac compatible?

Accepted Answer

As long as the hard drive is in a compatible format for your OS, It should work as any portable hard drive would.

Question 4

Does this unit come with the USB cable?

Accepted Answer

Yes

Question 5

NewEgg's specifications for this dock state maximum capacity up to 3TB. My employer owns one of these, but the only >3TB drive I presently have access to is a personal 4TB Seagate backup drive/enclosure that I'm not ready to crack open merely for testing.
Is this capacity/limitation accurate? I've noticed other dock specifications also state drive capacity limits. What in a drive dock would limit capacity? I'm guessing (perhaps incorrectly) that most drive docks have little if anything in the way of logic boards, caching, etc. that would be limiting factors...? Maybe the stated capacity limits for docks has to do with available drive capacities when a dock is released? If so, it makes more sense for dock creators/retailers to state that capacity limitations depend on available drive sizes and host/computer support.

Accepted Answer

I inserted my 3TB drive into it and it DID NOT recognize it. It may be because the drive was set as a GPT drive. It reset the drive and I had to recover all of the data.
