do i have to keep the hard-drive in an anti static bag
No just do not touch he circuit board underneath
With a SATA drive, the process is much easier to install than an IDE drive.
Simply plug the power connector into the drive, and connect the drive to the motherboard SATA controller using the supplied SATA cable. (Both connectors are both keyed to prevent improper connection.) With SATA drives, there is no need to change jumper settings, though you may need to update your computer's BIOS if it can't see the drive.
