Bests & Worsts Reviews from Amazon

I purchased this hard drive expecting it to behave like a typical external hard drive. I wanted to plug it in and see a single drive letter in My Computer. However, this drive has more "advanced" features that require WD software. The drive presents itself as a CD-ROM drive as well as a hard drive. This virtual CD drive is supposed to contain the drivers to use the advanced features. The hard drive is inaccessible without the WD software. However, Windows 7 x64 is unable to locate the drivers for the virtual CD drive. Therefore the advanced drivers cannot be installed. The drive is unusable on Windows 7 x64. WD does not provide any downloads on the website allowing you to manually install the proprietary software. I contacted support, they told me to wait for an update. They recommended an RMA, even though we both agreed that this was a software, not hardware issue. Even so, if this had worked properly it adds extra bloatware to your computer that is not necessary. I replaced this with an equivalent Seagate. The Seagate behaved exactly as expected, plugin -> drive letter, done. In summary, this drive requires proprietary software to function. This software does not work on Windows 7 x64 at this date. Get a drive without these requirements and save yourself a headache.
