Summary: I bought 2 of these and installed in my Dell XPS-400 Desktop. Installed without issue. Installed Windows 7 Home Premium without issue. Used Partition Wizard to make a few partitions without any problems. I like having 2 drives (one for backup).
Summary: What a great deal for a hard drive. Made the conversion to win7 easy as remove and replace. Fired right up and loaded 7.It meets all my needs and I always use WD drives after too many failures of other brands.
Summary: I'm trusting two of these (redundantly) in a mission-critical piece of lab hardware and they work fine so far. It's only been a month, but they haven't gone up in smoke yet, which is more than many products can claim. Excellently priced, that's for sure.
