Interesting. I bought a WD DVR expander the same day I bought my TiVo because I didn't want to open it up to enlarge the internal HDD and void the warranty. From the complaints of others at the time, I figured it would die soon after a year had passed; the TiVo would be out of warranty and I could upgrade the internal HDD -- that was over 4 yr ago. The WD Expander sits on its side in a well-ventilated open air rack so that it is barely warm to the touch. Perhaps that has something to do with its longevity.
One expander I bought is still working, mounted vertically, with an S3 and has never caused a problem.
The second was originally connected to another S3. I disconnected that S3 after a few weeks without problems. Like the first, that expander was mounted vertically with air free to circulate around it.
I then connected a 3rd expander to a TiVo HD which I'd set up to test its OTA tuner. The expander was mounted vertically in the same location as when the 2nd was connected to the 2nd S3.
I also moved the 2nd expander, mounted it vertically in a location where air could circulate around it and connected it to a MOXI. Within a month the MOXI failed.
I connected a 4th expander, laid on its side, to another S3. After a few weeks the S3 began spontaneously to lose its connection with the expander. I got it back OK, but it dropped the connection again after about 3 hours. I got it back again, but only for another 3 hrs.
I contacted TiVo support and they emailed me detailed instructions how to enable TiVo's Kickstart HDD analysis program. I could not get Kickstart to initialize after following the detailed instructions repeatedly. I then disconnected the 3rd expander from the HD and swapped its eSata cable with the one from the 4th expander and repeatedly attempted to get a connection from theS3 to the 4th expander without success. It would neither connect nor initialize Kickstart.
After spending way too much time on this nonsense I opted for the only thing still left to try and succeeded in getting the S3 to disconnect from the 4th expander. As soon as it did the S3 operated normally and still is.
Perhaps in my location a vertical mounting works better than horizontal but who really knows? I can't prove it of course but because of everything that happened I suspect that the 2nd expander had something to do with the MOXI's failure.
I was suspicious at first when learning that Weaknees advised against using WD external HDDs but now believe that there's more to their advice than merely promoting sales of their own pre-formatted HDDs.
The HDD fallibility issue, ultimately affecting all HDDs will, IMHO, within 10/15 years result in all DVR (as well as other) designs relying on spinning discs to become as obsolete as VCRs.
