Event viewer is showing bad blocks on my Raid hdd that is freezing after booting into Windows Server 03. I was thinking of running a chkdsk /r to fix it, but read about someone that used Seatools for DOS. What is the best software/app to use to fix a drive with bad blocks? Also, I will have to run the utility before booting into Windows, like from a CD iso image. Is there any chance of damage to the raid by running a utility on the C: drive?
