I would like to know the entire suggested process to correct the issue of scandisk not completing because it reports that I should enable LBA in the BIOS to claim back some incorrectly identifyied or lost clusters on the HD. Can a simple BIOS upgrade fix this or should I really enable LBA as stated? Also, there seems to be a common denominator with the PC’s I have seen with this problem lately – the Klez virus and damage done to the outbox in Outlook Express. Any suggestions will help.
