I have a external hardrive and some questions.

1) Is it ESATA (or whatever)? When I click properties it tells me it is a: HL-DT-ST DVDRAM GSA-T10N ATA Device

2) If it is a SATA can I put games on there and safely run them off the drive? Can I install programs (like itunes or skype) and have them run properly?

3) It came with a reeeeally crappy backup system that I quickly realized was waaay too stupid to use. Unfortunately, this was after it had backed up (or what it considers backed up). I was wondering if I could safely delete the backup folder and not compromise the actual drive. It tells me this in a notepad labelled: DO NOT MODIFY!! (with both exlamation points... how sad)

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<!--This file is automatically generated.-->
<DataCladFileStore>

</DataCladFileStore>

But if I'm not using the backup than I assume it is safe to delete or 'modify'.

4) I use Windows Live One Care on Vista and it's what I'm currently using for backing things up. Supposebly it backs all of the computer onto the hardrive you tell it to (in my case this external one). But all of the files are zipped and I have no idea what this means and if it IS a backup or if it's backing up both hardrives.

So, anyway, those are my questions.
