My computer contains 2 hard disks (80 GB, 40 GB). And I installed 2 operating systems (XP & ME) on it. Unfortunately when I was reinstalling, Windows ME on 40GB disk, I saw an error message about some cropped files and Win Me setup going to fix it. So I agree that. But after Window ME & XP was reinstalled, I couldn’t able to access all files on the 80GB hard disk. And 2 partitions join as one on the same disk and I lost all files, placed on those partitions. So computer gone too slowly. I think, boot sectors of disk had collapsed. So I repartitioned entire disk with the help of Windows XP Disk management Tools as 1 Primary and 1 Extended contains 4 logical drives (FAT 32 file system). But when I format these partitions on windows XP, progress of formatting gone 100% normally; But “Unable to complete formatting successfully” message appears on last! But we can able to access that drives on XP. But I can’t access it on DOS or ME. So I repartitioned that disk on win 98 DOS. But it shows only 12GB only. So I couldn’t able to partition as I wish. So I put whole disk as 1 partition; and dos formatted whole disk (about 76 GB) without any trouble. But I know using a large amount space as single drive will make many troubles. Now I have only one idea to over come this trouble. But I can’t sure, it’ll give success. That Defrag entire disk; then trying to partition. But I haven’t hope on that method and it’ll take a long time. Do you have any ideas to solve this trouble? This is an urgent problem to me; because I can’t able to access my computer smoothly now.:O So please reply as soon as possible.
