Spindown 0.2.2 (Default branch)
Spindown is a daemon to spin down idle disks andthus save energy and give the disks a longerlifetime. It also works with USB disks andhot-swappable disks because it uses the device IDto identify the disk instead of the device name(such as hda or sdb). This means that it doesn'tmatter if the disk is swapped while the daemon isrunning.License: GNU General Public License v3Changes:
The command configuration options now expect thewhole command to execute and not just only theparameters. It still defaults to "sg_start--stop". Gentoo init scripts were added. The FIFOis removed when shutting down the program.Image

diskscan

diskscan(1M)						  System Administration Commands					      diskscan(1M)

NAME

       diskscan - perform surface analysis

SYNOPSIS

       diskscan [-W] [-n] [-y] raw_device

DESCRIPTION

       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 parti-
       tion 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.

OPTIONS

       The following options are supported:

       -n    Causes  diskscan to suppress linefeeds when printing progress information on standard out.

       -W    Causes diskscan to perform write and read surface analysis. This type of surface analysis is destructive and should be  invoked  with
	     caution.

       -y    Causes  diskscan to suppress the warning regarding destruction of existing data that is issued when  -W is used.

OPERANDS

       The following operands are supported:

       raw_device    The address of the disk drive (see FILES).

FILES

       The raw device should be /dev/rdsk/c?[t?]d?[ps]?. See disks(1M) for an explanation of SCSI and IDE device naming conventions.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

NOTES

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