I recently installed a Western Digital Caviar 200GB JB (IDE with 8MB buffer) hard drive into my PC as a replacement for a Hitachi Deskstar 7K250 160GB SATA. It is currently the only hard drive in the system, and operates on the primary IDE channel. The system BIOS recognised the drive easily enough. One thing that does concern me is the fact that it only recognises 8.4GB out of 200GB. I know I need a Windows service pack and further software updates from Western Digital to reach the full capacity, but is it normal to have so little? Also, I noticed a 'clicking' sound coming from the hard drive and a high pitched 'whirring' sound. I also noticed this problem on the Deskstar which eventually stopped working after several weeks. Has anyone else come across this problem on a brand new HDD? If so, is there anything I can do to remedy the situation? I haven't installed the OS on the hard drive yet, nor is there any other data on it. If anyone has any suggestions, I'll be glad for the advice. Thanks.
