Question: My girlfriend has an old laptop-drive she wants me to grab data from. I want to buy a usb-adapter for it, but I have no clue as to which kind of disk this is. There are no text printed on the drive except from “Made in China” and “F4”.

The hard drive’s size is 7 cm 9,5 cm excluding the pins. It seems to be 24 columns of pins with 2 rows, (24 2 = 48) pins total. It is a small space between two columns of pins and the other 22 columns.

Answer: That would be an IDE (PATA) drive. The pins to the side are for jumpers, not the cable:

Given how antique these are now, I suggest a USB to IDE and SATA 2.5″ drive adapter as being of more use, and of similar cost, usually.
