Summary: I bought 2. I keep one in a fireproof safe, and use the one to pass around several different work stations. Never ran into any issues, it has fallen from standing upright to its side several times while on without resulting in any issues. Very durable, solid piece of equipment.
Pros: Idiot proof. Format from computer management before use. Manufacturer firmware prevents you from ever bricking the USB components necessary for comm between PC or Apple. Since I purchased this in 2011 (now 2013) I have disconnected the power via cable no less than a bajillion times; with no fail.
Cons: I have a corner unit desk, the power supply cable could stand to be another foot and a half or 2' longer. But no reason to knock off any eggs just because I have a large work station.
Summary: I like the space, but I was pissed when I found this hard drive has 2.0 usb and no firewire. I thought I had the right hard drive. I didnt read the specs correctly. This thing is affordable, but slower than a snail. 3.0usb or firewire is the only way to go. Dont waste your money people, stay up to date!!
Summary: I have an older (approx 5 yrs) Intel 20" iMac and needed more storage space for Time Capsule. I initially purchased a Seagate 2TB drive from Costco that said it was Mac and PC compatible. Despite many attempts, I was never able to get a backup to complete. The backup always froze a short amount into it and required my to abort/restart/power off. I finally returned the drive. I looked for one that was designated as specifically compatible with a Mac.
Summary: First of all, I am probably not the best person to be writing a review on something electronic, since most of what I know is pretty basic. However, I have been using this desktop hard drive now for about 2 weeks, and have had no problems with it. It's so quiet you can't even hear that it's on, and transferring large image files only takes a few minutes.
Summary: UPDATE, 09/23/2012: I contacted Western Digital, and because this product has a one-year warranty, I received a brand new product... in only TWO days! The hard drive is working perfectly, and I've had no problems. I absolutely recommend it for the reasons I mentioned in my original review, which is below. I changed my review from 2 stars to 4 stars. If the first one hadn't broken, I would have given it 5 stars.
Heads up if you are using an older MacBook and want to power directly from USB port
3 August 2012
Summary: Received this last week and was able to use it straight from the box...Very Plug and Play. Clean looking unit. 2T is fantastic! Only gripe is it is not able to power directly from USB port on my 2006 MacBook 2,1. The description says, "USB 2.0 interface - Powered directly from the USB port on your PC. No separate power supply is needed*.* An optional cable is available for the few computers that limit power from the USB port.".
