How to do data recovery on a SoftRAID/FakeRAID system?

I booted an old laptop (HP Pavilion dv7 Notebook PC) with a live cd.

I can see two hard drives and I suspect them to work in a RAID config (SoftRAID/FakeRAID) but one is 232GiB (250GB) and the other is 149GiB (160GB).

Is it possible? How to know if it’s the case?
