k of 3 partitions: 4G for drive C, 6G for drive D, the rest space is allocated for drive E. Recently there’s a failure appearing, every time when start up the computer, disk scanner would begin scanning drive D, besides, when the scanning goes to 10%, it stops. After skipping the disk scanner, the computer could work normally again.
Failure analysis and solution: it should be caused by physical bad track. Generally, as physical disk bad track could not be repaired, so it would be better to shield the bad track. You can start the computer with Windows 98 system disc, run fdisk command to repartition the disk, 4G for drive C, 1.4G space for drive D (as the disk scanner could not pass when scan to 10% of the drive D, as mainly we can calculate the position of the bad section, which is on 4+（20－4）×10%=5.6G of the disk), and then divide 500MB space for drive E (in order to include the entire bad section within on a single partition, so divide bad section space a little big). And divide about 4G for drive F, at last, the rest space is for drive G. After space division, delete the drive E where the allocated 500MB space is, later the disk magnetic head would not visit this area again. After finishing the disk partition, restart the computer and format the disk, then you can start installing operation system. After finishing installing Windows OS, you can unite the original allocated drive D and drive F into one partition with Partition Magic. In this case, physical bad track of the disk would be shielded.
