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.

Error free hoursĪs 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'. These sectors are first examined and verified by the Quick Fix function too. 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.

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. Generally SATA/IDE devices report more details than NVMe/SCSI/SAS drives.Ĭare must be taken to interpret the results as the displayed errors may cause false assumptions: sometimes perfect hard disk drives can log errors. 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. 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. additional, status, statistics depending on the device connection/type (see below).time-limited error recovery (TLER) values.temperature statistics, absolute maximum/minimum temperature limits, average temperatures.utilization type (read/write) and limit (for example 550 terabytes/year).functionality/features and current operating conditions, cache (buffer) size.device statistics collected during the operation (total amount of read/written data, start/stop cycles).the status/result of previous internal hardware self test(s).the internal error log of the hard disk drive / SSD.

last error timestamp and error free hours (see below).The Device Specific Information window generally displays 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. (Note: requires registered version of Hard Disk Sentinel Professional to fully utilise this function). 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.
