Table 16-4 Descriptions for analyze Menu Items
Subcommand |
Description |
read |
Reads each sector on the
current disk. Repairs defective blocks as a default. |

current disk without harming the data. Repairs defective blocks as a default. |
test |
Writes a
set of patterns to the disk without harming the data. Repairs defective blocks
as a default. |
write |
Writes a set of patterns to the disk then reads
back the data on the disk. Destroys existing data on the disk. Repairs
defective blocks as a default. |

reads back the data, and then compares it to the data in the
write buffer. Destroys existing data on the disk. Repairs defective blocks as a
default. |
purge |
Removes all data from the disk so that the data cannot
be retrieved by any means. Data is removed by writing three distinct patterns
over the entire disk (or a section of the disk). If the
verification passes, a hex-bit pattern is written over the entire disk (or a
section of the disk). Repairs defective blocks as a default. |
verify |
In the first pass,
writes unique data to each block on the entire disk. In the
next pass, reads and verifies the data. Destroys existing data on the disk.
Repairs defective blocks as a default. |

Verify media after formatting? yes
Enable extended messages? no
Restore defect list? yes
Restore disk label? yes |
config |
Displays the current analysis parameters. |
quit |
