So I just recently diagnosed my hard drive as having bad sectors and replaced it with a 750GB WD Caviar Black a few days ago. However, occasionally, as with my old hard drive, my system will lock up. When I reboot I get the following error: “Disk boot failure, please insert system disc and press enter.” Sometimes after a restart I will receive the same error, other times the hard drive will boot but my keyboard receives no power. I haven’t figured out why, but everything seems to sort itself out eventually.
It’s unlikely to be a drive problem (although if it is, note that your RMA period will likely be longer with Western Digital than the retailer). The chances of replacing a bad hard drive with another bad drive are infinitesimal—something like 3,720 to 1. Your problems are likely related to a bad SATA port on the motherboard, a bad SATA cable, or a power or data cable not firmly plugged in on the board. There’s also one other issue that could be causing the booting problem. Many older motherboards, oddly, change the boot order if a USB drive is connected to a USB port. Your booting issue could be related to this sporadic problem that only happens on occasion when you have a USB thumb drive installed.
On the other hand, the keyboard power issue could be indicative of problems with the motherboard itself. Just because you’re getting hard drive errors doesn’t mean it’s entirely a hard drive issue. A failing board or other component in the system, such as RAM, or the classic “bad cap” problem can sometimes induce similar errors.
