The following table describes the analyze menu items.
Table 10-4 Descriptions for analyze Menu Items
|
|
|
read
|
Reads each sector on the current disk. Repairs defective
blocks as a default.
|
|
refresh
|
Reads then writes data on the 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.
|
|
compare
|
Writes a set of patterns to the disk, 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.
|
|
print
|
Displays the data in the read/write buffer.
|
|
