Yeah, I know "connection issues" is very broad, but give me time an I'll explain to the best of my abilities what's going on. Right, so as the title states, I have a Seagate FreeAgent Pro, an external hard drive. This drive has four(4) different data connections. Esata, 1394a (6-pin), Mini USB (5-pin), and Mini Firewire (4-pin). My primary use for this drive is storage for video files as I do a lot of work with film. I've heard that the 6-pin Firewire (1394a) connection is the best for use with video, but being that I'm the curious chump, I wanted to see if the Esata connection would work any better or not. The two ports are the only two I've ever used since I first bought the drive, so I'm not too worried about the Mini ports. Here's my first problem: With the 1394 connection, I can plug in from the PC and the drive starts right up, and given a certain amount of time, it'll show up in Windows. However, with the Esata connection, I plug in from the PC and the drive will power up, but never show up in windows unless I restart the system, or run drive diagnostics (in which case it only shows up half the time). Here's my second problem: With the Esata connection, when I'm working in my video editing program and stop to take a break, the drive will shut off. When I try to get it going again, it never shows up and everything in the video editor brings up error codes because the links are all broken. I've also tried installing the software that came with the drive to change the 'Sleep' properties, but the window never opens even if the app is running in the taskbar - so I can't change the 'Sleep' properties. So overall, my question resides with the Esata connection. Would anyone happen to know why it works the way it has been described? Do I need to reinstall Sata drivers or what? I'm lost as to why the other port (1394a) works fine, but this one is so stubborn. Can someone maybe explain to me how Esata is supposed to work? Like is it the same as the internal sata drives or what? Any help would be awesome. Thanks in advance!
