Information about HDD health status.
Disk N Status
Disk Model: HDD vendor and
model read from IDE-controller.
Disk Size: Real HDD size
read from the IDE-controller. Due to the two different ways of
defining 'megabyte' your hard disk capacity can be calculated in
two different ways: after calculating the number of bytes in the
formula heads*sectors*cylinder*512-bytes-per-sector you may get the
result in the unit 'megabyte' by dividing either by 1024*1024 (like
in the BIOS of the computer does) or by 1000*1000 (like the
producers of hard disks do).
Interface Type:
ATA device interface type (Parallel ATA, Serial ATA I, Serial ATA
II, Serial ATA III, NVMe).
Serial Number: HDD unique
serial number.
Controller Revision: Number
of the revision returned by the IDE-controller.
Disk Marketing Size: The
marketing size much more than real size. In one 'computer' megabyte
of 1048576 bytes, but in one 'marketing' (used by HDD
manufacturers) of 1000000 bytes.
Buffer Size: Buffer size of
the IDE-controller (you shouldn't mix it up with disk cache). Part
of the buffer can be used for system
purposes, and its real size can be smaller. Some hard disks don't
provide information on the buffer size.
Location: Vendor and name
of ATA controller.
Device Location: Device
location on the ATA controller
Disk Temperature: Current
temperature of HDD.
Reallocated Sectors: Number
of reallocated sectors.
Disk Health Status: Can be
one of four values:
SSD Remaining Life: SSD
remaining life in persent.
Total Host Writes: Total
size of data written to SSD disk by the host system.
Total NAND Writes: Total
size of data written to SSD disk NAND memory.
Total Host Reads: Total
size of data read from SSD disk by the host system.
