I have found an old HDD that I never knew I had. I connected it up and it shows as being 298 Mb. However, when I try to use Explore, I just get a panel saying it's inaccessible and there is an incorrect parameter. I changed the drive letter but this didn't resolve it. I can feel it buzzing normally so mechanically it seems OK. Is there anything I can do? TIA.
 
320 Mb. I thinks it's about five years old, but can by no means be certain.
Are you mixing up 320MB with 320GB ? That is difference in x1000 (1024 to be precise).
And for 320GB drive, usable capacity is 298GB.
(because it is not actually 320GB but 320'000'000'000 bytes. You divide it with 1024x1024x1024, to get actual number in GB.)

Do you absolutely have to recover the data?
Is it of any importance?
Can you show a screenshot from Disk Management?
and a screenshot from HDtune health.
