CrystalDiskinfo – free utility to check harddisk/SSD health status

CrystalDiskInfo is one of the tools we turn to when we want as much useful data as possible about our system’s hard disk drives (HDDs) and solid-state drives (SSDs) as well as many external drives.

General Info here

Hard disk are used to store all types of digital data. But they are very susceptible to physical damage. It can develop bad sectors which can cause the loss of data. It can suffer mechanical failure of motor used in hard disk. Most of the time these hard disk failure don’t arise suddenly but slowly takes its. Almost every hard disk has SMART monitoring built in hard disk and SSD which can be used to predict the failure of hard disk. This is where CrystalDiskinfo comes in which can tell you what the hard disk health status is. It can warn you days or even months before the hard disk full failure. Bad condition of hard disk health tells that hard disk can fail anytime and you can backup your data while there is still time left. Also consider taking hard disk to the service center of that particular hard disk company for repair or replacement.

You can leave this software running on all the time. You can run it weekly or every month to check the health status of your hard disk.
If there is unusual crash of Windows OS then it is recommended that you run this software to check health status. Run it in situation of Blue screen crash, abnormal shut down, extreme slow down or hanging of computer, very high usage of hard disk (check hard disk indicator in laptop or desktop) which causes hanging of computer, when files on your computer gets corrupt. If your Windows OS gets corrupt then you try to install a fresh Windows OS then try to run this software to check if hard disk is failing or not.

  • AAM stands for automatic acoustic management. As shown below AAM has two extreme ends first is “silent” and second is “performance”. You can put the slider between or at these ends. Silent means you want your hard disk to produce noise as less as possible. Performance means you want more performance in terms of speed and don’t care how much noise the hard disk produces.
  • APM stands for Advanced power management. It has two extreme ends. First is “min power” which means you want as least as possible power to be consumed by the hard disk. Second is “performance” which means you want more performance it terms of read/write speed with increased power consumption.

  • You can get an alert sound when there is something wrong in your hard disk. You can also get email alert.

  • You can set this software to stay in notification area by selecting “resident” as shown below. With this the temperature of hard disk is shown in notification area along with the CrystalDiscInfo running minimized in notification area.

For laptop internal hard disk temp. should not increase 50 degree Celsius in normal operation and should not increase 55 degree Celsius for heavy operation. For desktop internal HD and for all external HD temp. should not increase 40 degree celsius in normal usage and should not increase 45 degree celsius in heavy usage. If hard disk temperature is very high then the cooling system of the computer needs improvement by cleaning or replacement of fan.
