Some files on drive won't copy because windows things drive is unformatted

[The Old Fart]

I plugged a second hard drive which connects via USB into my PC with the
view of copying some files to the main drive. The first couple of files
transfered OK. When I tried to transfer some more files I got the
message that the drive was unformatted & I was asked if I wished to
format the drive. I'm confused. If the drive wasn't formatted how did I
manages to transfer any files? How do I get the remaining files
transferred? I'm not planning to format the drive before file transfer
in completed.

Why not make a new folder on what you call the main drive and copy files to that
- if that works, you can eventually copy from that folder to where you really
need them. Do not format.
