I was interested in this external hard drive from Amazon that offers RAID options. (Please continue reading! This question is not simply "is this a good drive?" It's a specific question regarding an intriguing experience with the drive)

From one of the reviews, it seems, that someone had a drive fail - but it didn't go noticed - and because a drive failed, and they kept trying to write to it, the other one ended up an unformatted partition. Am I reading this right? I thought these types of drives were for the redundancy, and it doesn't make sense that the failure of one would CAUSE the failure of the other.
The part I understand least is "it displayed lights showing that it was re-establishing data parity on the internal drives" Could this cause both drives to fail if one is bad? Maybe someone could elaborate on this.
Perhaps I am reading the review wrong and they aren't saying the drive failure was causal of the other drive failure.
Here's the full text of the review. If anyone has insight into this, I would appreciate it:
"This is why it's important to actually test the main function of the product before writing a review. Finally had a drive fail (mechanically) last week. The enclosure was set to RAID 1 (redundant array) mode. Not only did the enclosure not notify me of drive failure (as the manual says it should), it displayed lights showing that it was re-establishing data parity on the internal drives. Lo and behold, after waiting 48+ hours (drives are 2TB), and suspicious that I could not even see the contents of the drive as the copy-over was occurring, I disconnected the unit to verify the problem. That's when I established that drive 1 had mechanically failed, and drive 2 was now an unformatted partition, rendering all data effectively destroyed. Testing, the unit STILL doesn't indicate by light the failed drive when it's placed inside (still lights blue for 'Drive OK' status). Ironically, I would have been better off keeping the drives separate and using a manual backup from one drive to the next. I'll try to salvage what I can with Recuva, but this is a fiasco."
Thank you so much for your help!
