HARD DISK MONITORING

Device Specific Information

By using Disk menu Device Specific Information function it possible to detect and report additional information about the actual hard disk drive / solid state drive / hybrid drive. (Note: requires registered version of Hard Disk Sentinel Professional to fully utilise this function). This information can be useful for advanced users to verify possible previous errors and general lifetime of a disk drive if used in a different system without active hard disk monitoring by Hard Disk Sentinel.

The Device Specific Information window generally displays

The amount of information (and the level of detail) depends on the hard disk drive / SSD: some disk drives can record and provide much more details than others. The disk controller/connection can also affect the operation: RAID configuration and some USB adapters/enclosures may cause that only limited information can be detected and reported. Generally SATA/IDE devices report more details than NVMe/SCSI/SAS drives.

Care must be taken to interpret the results as the displayed errors may cause false assumptions: sometimes perfect hard disk drives can log errors. This is generally normal and does not automatically indicate serious problems: in many cases compatibility issues, cable/connection problems or simply a bad chipset driver can cause that the disk drive may record problems in the internal error log. However, if the error may points on an actual sector of the disk drive, then the appropriate sector is (at least) suspicious - and listed at the end of the Device Specific Information page. These sectors are first examined and verified by the Quick Fix function too.

Error free hours

As some disk drives record a timestamp about when an error happened/recorded (in terms of power on time of the disk drive, not by recording the actual date/time) Hard Disk Sentinel uses these information to determine when the last error recorded - and also show how long time passed since the last error recorded as "error-free". This information may be not always possible (as some disk drives do not count/record such timestamp), but for most SATA/IDE hard disks and SSDs this can indicate how long the drive worked without any, even minor glitches.

Changes, possible degradations

Hard Disk Sentinel automatically records the information detected and reported when the Device Specific Information function used. When the window later re-opened, the changes since last check showed, for example [+5] in the appropriate line means +5 in the reported value (for example the amount of errors). It is also possible to re-load any previous log of the drive to examine possible changes, degradations, new issues.
