NAME

disk/smart, hdtemp – hard drive error monitoring

SYNOPSIS

disk/smart [ –aptv ] drive...
hdtemp drive...

DESCRIPTION

The disk/smart command uses the sd(3) raw interface for continuous disk health logging to /sys/log/smart and, with the –v flag, the console for ATA and SCSI disks supporting SMART–style reporting. The –t flag causes disk/smart to exit after a single probe and implies –v. With the –p flag or no arguments, disk/smart probes for all SMART–capable drives. With –a SMART–capable drives are announced. Logging behaves as if level triggered. If a smart condition is set it will be logged every 6 hours. Condition reset also resets the log timer.
Hdtemp prints the current drive temperature in Celsius if the drive and transport support it.
