hard drive has switched to raw system files

Hi,
I bought a seagate external desktop drive the other day and tried to format it. Now it is in raw file system, and won't let me access it. Is there a way to reformat back into ntfs.? Thanks

 

Go to Start > Run and type diskmgmt.msc and click OK. If the drive is listed there, right-click on it and select format.

 

I've tried that, it doesn't show up on there. I had a couple of viruses recently so there's a few things not working correctly.
Thanks

 

Then I suggest that you visit the manufacturers site for some installation software or diagnostic tool. Perhaps Here.

 

Yeah I've been on there too. this model was plug n play so there's no software. I think there's a bigger problem. I can't use anything on my control panel. There are no system restore dates available. I downloaded spybot to get rid of this fake antivirus virus that I had and everything has been going down hill since.
