The PC OS is WIN2000. I installed a disk manager program and after an hour or so i rebooted the PC. At start up i got a warning"Disk monitoring system shows h/drive operating outside normal specifications - replace HD." I can press F1 to carry on working but is there any way i can bypass this warning?Or is it because i have altered the hard drive? It is only a back up PC so it does not matter if it suddenly packs up. It has three partitions which i have tried to make into one - without success.They all format with NTFS OK.
