diskscan is used
by the system administrator to perform surface analysis on a portion of
a hard disk. The disk portion may be a raw partition or slice; it is identified
using its raw device name. By default, the specified portion of the disk
is read (non-destructive) and errors reported on standard error. In addition,
a progress report is printed on standard out. The list of bad blocks should
be saved in a file and later fed into addbadsec(1M)
, which will remap them.
- -W
- Causes diskscan to perform write and read surface analysis. This type
of surface analysis is destructive and should be invoked with caution.
- -n
- Causes diskscan to suppress linefeeds when printing progress information
on standard out.
- -y
- Causes diskscan to suppress the warning regarding destruction
of existing data that is issued when -W is used.
The raw device should
be /dev/rdsk/c?t?d?[ps]?.
