I was recently reformatting my hard drive when the power cord accidentally came out of the machine. When I went back to reformat the unallocated available space on the hard disk was 128GB instead of the anticipated 250GB. I proceeded with the format anyway and installed w2k server on the partition thinking that from within windows I would be able to recover the space. I was not able to see it using disk management tools. I thought to use partition magic but it's not supported with w2k server. I am about to reformat the machine again now some 10 months later and am concerned that once again the lost space will not be recognized during the reformat. Could the power loss have caused irreparable damage to just that one area of the disk? Are there other tools to help me locate the lost space before I go on to the reformat? Chkdsk doesn't see the lost space either.
