Having problems with booting up HP Pavilion 6 laptop, with WD5000BPVT hard drive. Re-Imaged the drive several times but booting up takes a long time. Ran WD diagnostics several times, with 08 error message. I think there is a bad sector in the boot partition, but somehow can’t get rid of it. Is there something else I can do, or do I need to replace the drive.
