Windows 7: My Computer cannot detect my Seagate external hard drive 3TB

Hi guys,

I've had this 3TB hard drive for about 6 months with no problems.

However, for some reason my computer cannot recognise it any more.

It doesn't come up in My Computer, but it comes up in device manager ( see pic 1) and in disk management (see pic 2)

Alarmingly, I can't even assign a letter or do anything but delete the volume (see pic 3)



I can't find the driver cd to install it but I didn't think this would be a problem as I installed it anyway through the computer. I've searched for about 2 days on this forums and others and still can't find a solution. I hope I can find one here

oh and i forgot to mention, i tried the hard drive on two different computers and it had the same problem there as well.

Your images still dont show - can you repost them using the little paperclip icon?

the pics are up now

Hi,

What was on this disk? Did you have MacOS or a variant installed to this disk?

nope, just movies and music

OK. I need a more experienced eye on this...I'll see if I can find someone to have a look at this for you.

I assume you want to avoid format this drive correct?

yes please, i'm a bit worried because this thread has 300 views or so and no-one has posted

Don't worry, we have hundreds of posts ever day, and its just a case of getting the right eye on it.

All you need to do is assign a driver letter to the drive by using a third party app like parigon disk suite (trial is free)

OK, I just had an idea. Lets see if this works.

1. Click Start, then in the search box, type cmd. Right-click CMD.exe, and choose to open as administrator.
2. In the CMD windows, type DISKPART, and hit enter.
3. Now type list disk and hit enter. Take a screen capture of the output and post it back here.
