OSStatus error 2

[incartek]

I have a Seagate external drive, attached by ethernet to computer or router (same problem on each). I am using it as a time machine backup. It used to work but now I am getting three problems.
1. When I try ago access it I am asked to enter the system password. It is not accepted even though it is correct
2. If I try to access is as guest I get the following error message - The operation couldn’t be completed. (OSStatus error 2.)
3. On a Seagate forum it suffused I reformatted the disk, but I cannot access it using disk utility.
So I am stiuck.
Can anybody help please ?

First question I would ask is…How do you know the hard drive is still properly functioning? If it worked previously…can't access it now…maybe the hard drive has failed.

I would confirm proper function of the HD before pursuing other things.
