Re: Possible for malware to covertly hide on harddrive sector
said by dave:Also what OP means by "reformatting". Such as, dropping any/all partitions, if any, first and not just format C:/system with existing partitions (if any) still in place. I assume OP means the second but pointing that out in case.
And whether it survives a "reformatting" depends on what that reformatting actually does.
