Lawyer in warehouse uses ploy to get computer disk (7,6)

'computer disk' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'lawyer in warehouse uses ploy' is the wordplay.
I cannot quite see how this works, but
'warehouse' could be 'storage' (synonyms) and 'storage' is found within the answer.
The remaining letters 'device' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'to get' is the link.

Can you help me to learn more?
