I recently purchased two Seagate Backup Plus Portable 750 GB drives and one Backup Plus Desktop 1.5 TB drive to use on several Windows 7 64-bit computers. I used one portable on a laptop and it works great. But last night, I tried to use the desktop drive on my desktop computer and I simply cannot get it to show up in Windows Explorer. It shows up as a "removable media" in my notification area and as a device in device manager (with the "Seagate Backup Plus Desk" name). But it does not show up under Storage in Disk Management within the Computer Management section of the Control Panel. I thought that perhaps the drive may be trying to use an in-use drive letter, or maybe it is simply not being assigned one, so I wanted to change it through here, but because it does not show up under Disk Management, I have no option of doing so.
According to Disk Management, nothing that is plugged in is using any drive except C.
D is assigned to my DVD drive, but it does not show up within the Disk Management window. This leads me to ask the question: how can I figure out what drive letters are in use? I recall doing some sort of drive mapping unsuccessfully on my camera to try to get some pictures back a while ago, and I'm not sure if I changed something else then. I've also used software like MagicISO in the past to run virtual drives, but they are all disabled (I've always disabled them when not in use), and the software is long uninstalled.
I plugged in my Backup Plus Portable to this same computer, and a similar thing happened, but the device did show up under Disk Management, but without a letter. I assigned a letter and autorun ran and the drive showed up in Windows Explorer.
I plugged in my Backup Plus Desktop to my laptop, and it worked the first time I did it. I then proceeded to use the Seagate DiscWizard to try to identify my drive in my desktop. I clicked on "Add new disc," selected the drive, selected the "MBR layout" initialization process, and created a new partition as part of this process. I got a message stating something like "There may be important data on this disk crucial to proper functioning," but since I read this suggestion elsewhere to try to identify the drive, I proceeded to do it, anyway. At this point, I did not know that I can assign a new drive letter, so I did not assign a non-default one via the options.
Did I end up erasing some crucial data to make the drive run properly? The reason I ask is because the Backup Plus Desktop is no longer showing up in the laptop, but it did the first time as I mentioned previously. I'm not sure if it is related. The drive still shows up in Device Manager, but not in Disk Management, which is exactly the issue on my desktop. Also, I tried installing DiscWizard again, and the installation was successful, so the program did recognize the drive, but then it gave me an error that said "Failed to read from sector '-387,938,129' of hard disc '2'. I then tried to partition it as a GPT as a final resort, and the software gave me the same error. I was able to ignore the error and got the message that the process completed "successfully."
What are my options at this point?

After running the DiscWizard, the drive showed up in Disk Management and Windows Explorer, but only as "Local Disk X". I'm assuming that some identifying data was deleted off the drive. I also get very basic autorun options when it's connected, like it's a generic removable drive. I also get the generic Windows hard drive icon, not the Seagate one.
But it seems like I can use the drive as a backup drive via Windows Backup (which is how I used the portalbe drive on my laptop, anyway). But I'm very concerned about the errors I received and how Windows is handling this drive in terms of the icon, name, etc.
Is there a way to "reset" the drive via firmware or drivers?

Here is what I'd like you to do first, please:
Then if you're still seeing weird problems like this, please run a SeaTools test on it.

I formatted the drive and then ran several SeaTools tests, including the lengthy "long generic" test. There are no issues, at least none that were reported.
Should I be worried about the missing Seagate icon (it is currently replaced by a generic Windows 7 hard drive icon)? Has the drive been "reset" to its original settings?
Am I missing any features with what seems to now be a regular, bare hard drive?

I tried to do a backup last night using Windows Backup. I got an error code, 0x80070002, with the following message: "Check your backup," followed by ""the system cannot find the file specified." The newly-created backup is about 20 GB less than my used hard drive space, so I'm assuming not everything was backed up, even though I selected for everything to be.
Microsoft states that this will happen if:
I'm not sure what my USB 2.0 controller is, but my USB 3.0 controller is made by NEC Electronics, which is the one I use. My standard USB 2.0 controller is listed generically as USB root hub, etc. ASUS's site does not provide any USB 2.0 drivers for my motherboard, just USB 3.0, which are updated.

Try some of this, please.

Here is a list of things that I've tried:
- Updated all drivers, including my NEC USB 3.0 drivers and my USB 2.0 drivers
- Ran a backup using the USB 3.0 drive and a USB 2.0 drive
- Used a Seagate Backup Plus 750 GB Portable drive (instead of the 1.5 TB Backup Plus Desktop drive)
In every instance, I received the same error when using Windows Backup.
I then tried to use the Seagate Dashboard. I found that it could not make Windows disk images and so I tried using Seagate DiscWizard. While both of them completed with no errors, the backup sizes while using both programs did not match up with the occupied hard disk space on my hard drive (321 GB on my hard drive vs 253 GB backup when using DiscWizard). I noticed that it used "normal compression," which may explain the difference in sizes. Should the backup and my occupied hard disk space be 1:1 if I choose to back up everything, including Windows?
I also have another question: does the Seagate DiscWizard make system images? If so, in the event of my installed hard drive crashing, how do I migrate this image and all of my files onto a new hard drive? Obviously, I do not wish to reinstall Windows under such a circumstance -- do I simply run the Seagate Backup Plus drive with first priority in BIOS and it will take care of itself from there?

Yes, I think DiscWizard compresses stuff, so that may well explain the different sizes.
DiscWizard does do system images, yes.
And it can do the system transfer you mentioned.

I have a brand new 2T back up plus, auto play triggered to open it, fine..But same as above. It will not show up anywhere else buy disk mgr and device mgr. Can not open it otherwise. Have it plugged into USB 3 . All is totally up to date, I went through every single item to update driver and check for new hardware, which weren't the issues, did it any way. I don't think this is any Seagate issue. It is microsoft/os issue. I have a fine 500Mb back up plus. win exp can't tell the difference even though I added a distinguisher to the new Back up Plus, so I could tell one from the other. I manually assigned a letter as well. Still no show.
sorry if I am not supposed to jump in...
