Well, I don't know what to say. My brand new 640 GB My Book Essentials had a freeze up tonight while recording "The Office" from our one LIL HD feed, just like the LaCie drive did. So, it's either a problem with my ViP 211, or it's a problem with the DVR feature in general. Since I've read only two people that have had this issue, I'm leaning towards the former.
I'm copying the events from the LaCie drive over to the My Book right now. I'm curious to see if the directory gets recreated at boot time. Also, like I said, I had recorded some events to the My Book EHD, so I had to rename those Event files so I didn't overwrite them.
For the curious, the third partition is UNIX/Linux EXT3 and contains the recorded events, consisting of three files for each event: esnnnn.bm, esnnnn.tsp, and esnnnn.wtt, where "nnnn" is a sequential number starting with "8000" and incrementing one for each event. The .bm (Bill of Materials?) file contains the Program Information of the event, so you can use a hexdump utility to see the Event name(s) and Description(s) in clear ASCII text (if the event spans multiple programs, you'll see Program Titles and Descriptions for each one). The .tsp file is the largest of the three and contains the encrypted Transport Stream (I assume; it makes no sense to my human eyes). I don't know that the .wtt file is, but it might contain pointers into the .tsp file (WAG) and the longer the event is, the larger this file is.
I'll post later if this simple rename and copy worked out, but for now, the copy of 225,512 MB is crawling along at 19 MB/s. Do the math... G'night!
