DESCRIPTION
This shows the current status of the hard disk (a green circle with a check mark indicates healthy).
This shows the overall health of the hard disk based on S.M.A.R.T diagnostics.
This shows the temperature of the hard disk in degrees celsius (
This shows your hard disk's performance (Good or Bad).
This field shows the number of hours the hard disk has been in power-on state since it was
produced.
This field shows the total number of spin start retry attempts. This is the number of attempts to spin
up to fully operational speed the hard drive has made when the first attempt did not succeed. An
increase in this value is an indicator of hard disk mechanical subsystem problems.
This field shows the total number of reallocated sectors on the hard drive. When the hard drive
detects a read/write/verification error, it marks the sector as "reallocated" and transfers the data
to a specially reserved (spare) area. The process is also known as remapping with "reallocated"
sectors known as remaps. The more sectors the hard disk has to reallocate, the slower read and
write speeds become.
This field shows the model family of the hard disk.
This field shows the hard disk model number that uniquely identifies a hard disk.
This field shows this individual hard disk's serial number from the manufacturer.
This field shows the hard disk's Logical Unit World Wide Name Device Identifier.
This field shows the version number of the hard disk's internal operating software.
This field shows the hard disk's usable size.
This field shows the sector size of the hard disk. A sector is the smallest physical storage unit on a
hard disk. Normally it is 512 bytes.
This field shows the rotational speed of the hard disk, measured in revolutions per minute (rpm).
This field shows the hard disk's Advanced Technology Attachment version number.
This field shows the hard disk's Serial ATA (SATA) version number.
This field shows the local time that the hard disk is using.
This field shows whether or not the hard disk is SMART-capable.
This field shows whether or not the hard disk has SMART monitoring turned on.
