USED, Hard Disk, SAMSUNG, SV0842D, Desktop, IDE, 8.4GB

Hard disk and PCB condition information.

If a Hard disk has a HDDxxx reference number, then it is a used working disk, with a clean bill of health in SMART (no bad sectors e.t.c.)

The disks with a generic photo are sold on Specification (Data size, interface and physical size).

HDDxxx disks that have a real photo are sold as that exact model, for use as a good disk, or to use the PCB for repair.

If a Hard disk has a HDBxxx reference number, then it is either a PCB only (for repairing a disk with a bad PCB), or it's a complete working disk - which probably has some bad sectors e.t.c. in the SMART data, it's being sold as a PCB for repair, but with the rest of the disk, so you can see it functions.
