While running Surface Scan Hard Disk, the computer was powered down and some data on the hard disk was lost. What happened?
The Surface Scan Hard Disk utility has two subtests, Write/Verify Test and Write/Read Test, which under normal circumstances run without destroying data. However, if the PC loses power or you restart it while testing is in progress, you may lose data. Service Center for DOS displays a warning about potential data loss when you select these tests. Do not turn off or reboot the PC while either of these tests run.
