To prevent interoperability problems that could occur when next generation SATA drives are installed on motherboards with legacy standard SATA 1.5 Gbit/s motherboard host controllers, many manufacturers have made it easy to switch those newer drives to the previous standard's mode. For example, Seagate/Maxtor has added a user-accessible jumper-switch, known as the Force 150, to enable the drive to be switched between 1.5 Gbit/s and 3 Gbit/s operation. Western Digital uses a jumper setting called OPT1 Enabled to force 1.5 Gbit/s data transfer speed (OPT1 is enabled by putting the jumper on pins 5 & 6). Samsung drives can be switched to 1.5 Gbit/s mode using software that may be downloaded from the manufacturer's website. Upgrading a Samsung drive in this manner requires the temporary use of a SATA-2 (SATA 3.0 Gbit/s) controller while programming the drive.

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.

If not, you may have lost your data. You can try recovery applications like SpinRite (grc.com), but (good as it is) there is no guaranty. ... Thinkpads_User
