Wish that I had found this thread before ordering parts.
However, it looks like I may have gotten lucky.
My set-up seems to be working (although the TV guide does not seem to be populated with much data?).
I have an HR24-200.
1. Rosewill RX-358 V2 SLV (Silver) 3.5" SATA to USB & eSATA External Enclosure w/Int.80mm Fan
2. Western Digital Red WD20EFRX 2TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive (probably did not need to actually get a WD Red, but I wanted a drive that I could use in my PC if I could not get it to work with the DVR -- and I do not really trust the WD Greens for my PC and definitely do not trust the Seagates anymore).
3. eSATA cable that came with the Rosewill enclosure.
Sorry that I could not provide links but the systems is blocking URLs since I am a newbie.
I spoke too soon. Had my set up working for a day. But then had to move my DVR (and unplug it). Went back through the same process and now the DVR only goes to the internal drive.
Is there anything special that I need to do to the hard drive after first time use to get it to work again?
