13 diskscan is used by the system administrator to perform surface analy‐
14 sis on a portion of a hard disk. The disk portion may be a raw parti‐
15 tion or slice; it is identified using its raw device name. By default,
16 the specified portion of the disk is read (non-destructive) and errors
17 reported on standard error. In addition, a progress report is printed
18 on standard out. The list of bad blocks should be saved in a file and
19 later fed into addbadsec(1M), which will remap them.
20
22 The following options are supported:
23
24 -n Causes diskscan to suppress linefeeds when printing progress
25 information on standard out.
26
27
28 -W Causes diskscan to perform write and read surface analysis. This
29 type of surface analysis is destructive and should be invoked
30 with caution.
31
32
33 -y Causes diskscan to suppress the warning regarding destruction of
34 existing data that is issued when -W is used.

36
38 The following operands are supported:
39
40 raw_device The address of the disk drive (see FILES).
41
42
44 The raw device should be /dev/rdsk/c?[t?]d?[ps]?. See disks(1M) for an
45 explanation of SCSI and IDE device naming conventions.

66 The format(1M) utility is available to format, label, analyze, and
67 repair SCSI disks. This utility is included with the diskscan, addbad‐
68 sec(1M), fdisk(1M), and fmthard(1M) commands available for x86. To for‐
69 mat an IDE disk, use the DOS format utility; however, to label, ana‐
70 lyze, or repair IDE disks on x86 systems, use the Solaris format(1M)
71 utility.
