Wondering if anyone is using a dock like this one (http://tinyurl.com/a2u7auz) and bare hard drives with any of the DVRs? As 3.5 inch HDs have become bigger and cheaper it seems that pretty much the only 1-T drives available are bus powered 2.5s. I'd prefer 1-T drives because anything bigger seems to take forever to connect.
If it'll work I'm also thinking that using a dock would also allow easily swapping drives. I've used the Monoprice USB switch with multiple HDs, but it's never worked reliably for me even though I was very careful to switch off one drive before bringing another on-line.
