Question?
 

Currently using 4.12.3

What does 'disk problem' mean? I got this message when one of my downloads finished.

Think the most common reasons are that either harddisk is close to full or it needs defragmenting. That's not always the case though. Try checking those things first.

If it's none of those things that are wrong then try searching the forum for answers first before posting again.

look for disk problem and disk error

The answers might very well be there somewhere

Thanks for help.
