Sneaky Hard Drives
So it turns out that the hard drive I was trying to mount in the enclosure I’d bought was being sneaky: it behaved normally just long enough for me to write a post about the enclosure being broken, mount the drive internally, and return the enclosure to the store. Then it stopped working entirely. I guess the days of constantly streaming video to and from itself in the PVR finally got to it.
I stand by my statements about Dynex’s non-existent troubleshooting documentation, but the enclosure was probably fine. It’s a moot point now though, since it’s gone and I bought an external Seagate FreeAgent 320gb drive which seems to be working just fine.
