HDD2H03, 160gb...The contacts are arranged as follows:
xxxxxxxxxxxxxxx xxxxxxx and 4 pins xxxx what are the 4 pins for? Are they jumper pins or power supply?
More abouthard drive connection pins
The 4 pins are for a four pin power molex from the PSU. If your power supply has a SATA power connection, use it on the drive, otherwise use a standard four pin molex. DO NOT use both power connetors at the same time as it can damage the hard drive.
