Hi Jake025,
As you already know... adding a second Hard Drive to an UTV has been attempted before, and as of yet... has been unsuccessful.
As far as I know, there hasn't actually been a "Add a Second Hard Drive to your UTV" Project/Experiment conducted (by more then one or two people)which has made an effort to detail what DOES NOT WORK and what,if anything, DOES WORK when trying to upgrade the UTV to two drives.
IF a second Hard Drive is possible under current UTV Software (3.5/3.7) I'd like to suggest that ONLY an ATA Security Supported Hard Drive would work. (Like two identical UTV 40/45 GB drives)
Based on what we know about getting just one drive to work under UTV it seems likely that you MUST have ATA Security before a second drive would work...
This may all be a pipe dream (How would the UTV OS "span" two drives? How does Tivo do it?) but if we start with the assumption it is possible and carefully see what a UTV will do with two Hard Drives configured in various ways we may discover something...
Has anyone been able to configure the UTV to "ignore" a Second Drive? (No Error codes) Even if it doesn't (seem to) add recording capacity?
Good Luck,
