Something struck me as very DD today as I was transferring files between drives:
The 2TB WD HDD was suddenly - or was I wrong the whole time? - reporting only 1TB max capacity.

It is attached via a dock and USB3, but I am CERtain that it used to report 2 TB max.

Now I am very susspickious of it, and I'll have to get another drive to use in its place.

Any insights into this tale of incipient woe would be appreciated.
