Checking a disk's SMART data using iRecover
 Self Monitoring Analysis and Reporting Technology
Self Monitoring Analysis and Reporting Technology - S.M.A.R.T., also often written as 'SMART' is is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SDDs).

Theoretically, as long as Windows or your system BIOS doesn't alarm you of imminent disk failure your disk should be OK. However, if the cause of your data loss is unknown we suggest you take a look at the SMART data. iRecover has a utility to view this data built-in.

To be able to observe SMART details, the hard disk needs to be directly connected (e.g. not through USB, not inside a NAS).

Checking a disk's SMART status using iRecover:

Click 'Data Recovery for Windows and Linux' > Select the physical disk from the list > Click 'More functions' > Click 'S.M.A.R.T. information'.

In the below screenshot we have highlighted 'attributes' that you need to pay special attention to; Reallocated Sectors, Reallocation Events and Current Pending Sectors. It is very well possible that the values in the RAW column for these attributes are non-zero. Non-zero raw values combined with data loss however are reason for alarm! If you observe non-zero values for these attributes you may want to contact us and sent us the SMART report (click 'Save to file') so we can determine if it is safe to perform data recovery on the disk directly. The alternatives would be to first create a disk image (so we only need to read it once) or to sent the disk to a data recovery lab.
