MyBook AV with Comcast Motorola DCH4316

I bought the MyBook AV 1TB for use with a Comcast Motorola DCH4316 HD DVR. So far so good. It changed my DVR recordings from 77% full to 10% full. I never power off my cable box but my question is can I power off the external drive without loss of data or does it have to stay on all the time, too.

Hello,

This actually depends on the DVR and not the My Book Drive. Check the DVR user’s manual for this.

The DVR user manual says nothing about external hard drive expanders.

Fairly typical for this board to post stuff and get no response when the going gets tough.
