Typical problem: where can I find the connected hard drive on the computer?

I’ve connected my 320 GB Seagate external drive to my computer correctly, and it’s confirmed a successful connection. But I can’t find the drive listed with a letter like G or H... It's weird. I am totally sure that the external drive has been detected. What should I do? It's a brand-new drive and it’s frustrating not to be able to use it. Do you know how to fix external hard drive not showing up in a computer?

Many people have come across this problem. Despite the drive being correctly connected to the computer, it does not show up as it should.  There’s also a common, related problem where, in Windows disk management, there can be a huge unallocated space on a hard drive, rather than partitions with drive letters. It seems like an impossible problem to solve. How can you use a drive if the computer doesn’t appear to allow you to access it? 

We have the perfect solution: a fix tool called a partition manager.
