Well with XP Pro alone i could not do anything with it. I used Acronis in Add New Disk mode and had no problems formating to NTFS. So you will need some formating app.
I can see the drive in XP Pro (Disk Management) but no way to format. I’m not going to load Linux so your on your own there.
I just hooked it back up to my 622 and it formated to whatever it uses again no problems.
Also if i remember correctly to use this feature on the 622 the HDD has to be at least 40gigs and not exceeding 750 gigs. No flash (thumb) drives can be used. Dish Pocket drives will work though. This is info from a Dish tech i talked to.
