What is the number of times a computer hard disk is used?

The number of times a computer hard disk is used is actually the number of times the hard disk is turned on. From power on to power off, this counts as one time. The next time it is turned on and then turned off, it counts as the 2nd time.

The exact description should be called "power-on times" which is more scientific. Sometimes users refer to the number of times a device has been used, which is the term used in the LUMA test. General brand-name machine factory, the manufacturer to install the system to the computer, start repeated boot install the system and test, generally 10 or 20 times the number of power is normal.

All hard disks come with a self-health recording software called S.M.A.R.T. This information is inside the hard disk and can be read read read by the software.

Extended Information

?

S.M.A.R.T. monitors objects including heads, disks, motors, circuits, etc. The monitoring circuits of the hard disk and the monitoring software on the host computer analyze and compare the operation of the monitored objects with the historical records and the preset safety values, and automatically send a warning to the

With S.M.A.R.T. technology, it is indeed possible to effectively predict potential hard drive failures and improve data security. But we should also see that S.M.A.R.T. technology is not omnipotent, it can only monitor gradual failures, and for some sudden failures, such as sudden breakage of platters, the hard disk is no longer smart can not help. So no matter what, backups are still a must.
