DISK Test/Clean This test causes the file system to scan the disk for bad sectors and remove these blocks from the addressed space. This test destroys all data on the disk and should not be attempted on a good disk. Normally you only use this test when the disk contains bad data and is therefore unusable. The test executes in two phases: a writing or cleaning phase and a verifying or testing phase. This can be an extremely lengthy test depending on the size of the disk. Each phase of the test on a 540 MB hard disk takes approximately 14 minutes to complete. This test leaves the disk unformatted. The servicer or user must reformat the disk using the Format Disk menu operation. Diagnostic Information 2-57
