The included TLER-ON.BAT will set the Read & Write TLER time to seven seconds. It is possible to use the WDTLER.EXE utility directly with the -r# -w# parameters for a custom timeout. Western Digital claims that using the WDTLER.EXE utility on newer drives can damage the firmware and make the disk unusable. The utility is no longer available ...
Floppy disk drives have sustained "disk-to-buffer" data transfer rates that are one or two orders of magnitude lower than that of HDDs. The sustained "disk-to- buffer " data transfer rates varies amongst families of Optical disk drives with the slowest 1x CDs at 1.23 Mbit/s floppy-like while a high performance 12x Blu-ray drive at 432 Mbit/s ...
Input/output operations per second (IOPS, pronounced eye-ops) is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN).
Power-on hours is intended to indicate a remaining lifetime prediction for hard drives and solid state drives, generally, "the total expected life-time of a hard disk is 5 years" [3] or 43,800 hours of constant use. [4] [5] Typically, after a disk reaches 5 years or 43,800 of power-on time, it is no longer in perfect condition and therefore is ...
The disk drives would measure the disk's "health parameters", and the values would be transferred to the operating system and user-space monitoring software. Each disk drive vendor was free to decide which parameters were to be included for monitoring, and what their thresholds should be. The unification was at the protocol level with the host.
Gizmo's Freeware directory featured WinDirStat in a January 2010 list of best free disk analysis software with a 4 of 5 stars review, noting: "The open source program WinDirStat is [an] outstanding program. It uses three ways to display the disk usage: a directory list, a file extension list and a rectangular treemap.

Read/write head from circa-1998 Fujitsu 3.5" hard disk (approx. 2.0 mm x 3.0 mm) Microphotograph of an older generation hard disk drive head and slider (1990s) Noises from an old hard drive while attempting to read data from bad sectors. During normal operation, heads in HDDs fly above the data recorded on the disks.
