I've seen a ton of support in this thread for the Thermaltake BlacX N0028USU eSATA dock.
I found another TT enclosure that looks tons cooler and has twin fans to cool a WD20EURS.
The Thermaltake ST0021U Max 5 twin fan eSATA enclosure has a much newer manufacture date (2010) compared to the BlacX (2005).
I'm having trouble understanding why the twin fan enclosure hasn't been brought up previously in this thread. It has an active cooling system vs. a passive one and even though the dock allows for easy HDD swaps, the Directv HD DVR would never allow for swapping HDDs back and forth. If you shelved a full HDD and swapped in a new one, if you went back to swap in the shelved one, it'd just reformat the drive as a new one. I'm saying this rhetorically because I'm sure everyone in here already knows that.
What I have right now is an old WD 1.5 TB My Book Home Edition that has an eSATA port on the back. Never unboxed it until 3 weeks ago when I got the HR24 installed. I'd gotten it a couple of years ago at a Best Buy Black Friday event for a future DVR that I haven't gotten until now.
The only thing that stopped me from plugging it in was the lack of an eSATA cable. Now that my DVR is about 50% full, I want to try what I have before dropping coin on the TT enclosure. I know I won't have access to the internal HDD once I plug in the MBHE, but if anyone knows for sure that the MBHE is inviting nothing but migraines I won't even bother trying it out. I have other WD externals in the house and the things tend to go to sleep on their own when not being utilized.
Reading up on the HDD spin technology in the EURS has made me a believer already.
So to nutshell it: Do I bother even trying the MBHE and why is the passively cooled, lame looking docking station so much more popular than the actively cooled, newer HDD enclosure?
Thanks for your time!
