However, either hard drives or SSDs have an lifespan, and they can also get damaged due to various factors, leading to data loss. It is hard to afford to lose important files which have not been backed up.

How do I check HDD health in Windows 11/10/8/7? The hard drive or SSD is the most vital component inside your computer, for it is the very place that your files are stored. How can I check the hard disk health so that I can make sure if I need to replace it with a new one? I'm not a computer geek and want to know a simple method to go. The program measures operation time."One of the partitions turned into RAW without any signs, and I'm afraid if there are underlying problems with the old hard disk. Test ends in the middle of the testing area. The first block in the first pair will be Block 0, the second block in the first pair will be Block N (where N is number of last block for testing).

Butterfly Read mode is similar to Read mode difference only in blocks' order.

The program tests blocks one by one from minimum to maximum. The program sends the block of data to the drive and the drive writes the block (All previous data in the block on the drive will be overwritten with the pattern and cannot be recovered after that!) The program measures operation time for each block.

In Erase mode the program prepares block of data field with special pattern and an LBA number.

The program reads block of data into a temporary buffer and measures time of operation for each block.

In Read mode device reads block of data and transfers it thorough interface to the host controller.

The program measures operation time for each block. In Verify mode device reads block of data into drive's internal buffer only and checks for consistency, there is no data transfer through an interface connector/cable.

Verify test may work in unreliable way on USB/Flash devices.Verify test may have restrictions on Block Size with 256, 16384 or 65536 sectors because of Windows limitations.Author wasn't able to get stable test results with two or more simultaneous tests. The program should not be run from a read-only device/media.Windows XP SP3, Windows Server 2003 (with restrictions), Windows Vista, Windows 7, Windows 8, Windows 10.Spindle start/stop function on ATA/SATA/USB/FireWire/SCSI HDD.Reporting defect information on SCSI HDD.Changing AAM, APM, PM parameters on ATA/SATA/USB/FireWire HDD.Reading and analyzing identity information from ATA/SATA/USB/FireWire/SCSI HDD.Temperature monitor for ATA/SATA/USB/FireWire/SCSI HDD.SMART tests running on ATA/SATA/USB/FireWire HDD.

Reading in linear mode – same as verification but also transfers data to the host.Verification in linear mode – fastest way to determine if your drive needs data rescue, has recoverable errors or in its perfect shape.USB Flash (pen drives) – surface tests only.RAID volumes made of ATA (IDE) / SATA / SCSI HDDs (surface tests only).FireWire or IEEE 1394 HDD (see Appendix A).External USB drives and all major USB boxes (see Appendix A).
