[RESOLVED] New Seasgate external HDD

Got a replacement Seagate 1TB external HD to replace the one I was using for backups. Attempted to format it by opening Computer icon on my desktop but the drive is not recognized. Used 2 different USB ports to no avail so I used Disk Management and used the "long" format(took about 26 hours) and now this drive in shown in Disk Management per this attached image . I don't know what I did to cause such results but just as important, what do I do to correct this problem? I thought about deleting the drive and start over but I should get your input first. I can't make a backup of Win 7 on my Compaq without the drive to capture the backup. Probably won't format a drive again using the "long" format proceedure even though I don't see that that would made a difference.

Did you try right-clicking it and assigning it a drive letter?

(Formatting and accessing through USB 2.0 is extremely s-l-o-w, especially when compared to USB 3.0, or even better yet, a direct connection to the motherboard).

Is the new drive a USB 3.0? Are you connecting via a USB 2.0 port? Although they say they are retro compatible my experience has been otherwise.

You are undoubtedly correct Doc; USB 2 is painfully slow but I just left it running through the night and most of today and most of Saturday.
Many thanks for your answer and I was just "on m way" back here to post that a friend helped me with the correct answer; the same answer you have given me.
EDIT: I overlooked your reply jseidel but my PC has the USB 2.0 only.

Good to hear the problem's been solved. Thanks for letting us know. :)
