How to: monitor (micro) SD card health and status

In this tutorial, it is described about how to monitor the complete status of appropriate industry standard (micro) SD cards, USB devices with Hard Disk Sentinel.

While most SD/microSD cards offer no status information and they can be tested only with the Disk menu -> Surface test functions in Hard Disk Sentinel Professional, many industrial SD / industrial micro SD cards can provide status information. Hard Disk Sentinel Professional (since version 4.71.7) supports these and the their status (health, complete self-monitoring S.M.A.R.T. data, error counters and statistical information) are detected and provided.

The detection of the status is not automatic as performing detection of a different type of SD card may cause performance degradation and unneccessary wear. Because of this, the device type need to be detected first with Hard Disk Sentinel Professional, and then every time it automatically detects the complete status.

Initial setup of monitoring SD card status

After plugging the device by an appropriate memory card reader, the card reader is displayed with "unknown" status:

Memory card reader with unknown status

Then click on Control device-specific detection on the right to open a window where it is possible to select the type of the device and enable the status detection of the SD card. A new window opens:

Control device-specific detection

Click on Auto detect on the bottom. The software will perform auto-detection and if the proper SD/microSD memory card inserted, should be able to determine its manufacturer and type.

Device-specific detection completed, device type detected

And after clicking OK in the message window and then OK in the previously opened window, the complete status should appear:

Status of the microSD SD card

The S.M.A.R.T. tab lists the device status, including error counters, lifetime statistics, total amount of data written / read, wear information, spare blocks, ECC information and so.

ECC error correction counters of the microSD SD card

The Information tab shows the device basic information.

Generic information of the detected microSD SD card

Now, after complete close / restart, the registered version of Hard Disk Sentinel Professional will immediately recognise the device, so no need to detect type again later, need to be done only once on this system. By the unregistered (trial) version, the device type is not saved, so the above steps need to be done again after restart.

Technical details

Hard Disk Sentinel Professional saves a special hidden "flag" file on the SD card and automatically detect its presence which allows using the appropriate status detection for the corresponding device. This file uses no disk space (0 bytes in length) and should remain on the SD card. If removed and/or the SD card re-formatted, the above mentioned steps need to be done again to initiate the status detection.

Note: the status information, error counters are not stored in user accessible sectors. Clearing, re-formatting the SD card or even using the industrial and government standard data destruction method (Disk menu -> Surface test -> Reinitailise Disk Surface test in Hard Disk Sentinel Professional) will not clear / restore the status and possible errors of the SD / microSD cards.

Memory card readers

To perform the detection, newer SD / microSD card reader/adapter may be required, usually these are marked to be compatible with newer SDHC and SDXC memory cards.

Some examples:

Supported micro SD / SD card models

Apart from their industrial grade which offers higher level of reliability, as the complete status (SD card health, SD card status, SD card error countrs and generally SD card S.M.A.R.T.) can be determined, monitored by Hard Disk Sentinel - and this way it is possible to be prepeared about problems, degradations, we strongly recommend to select and use the following devices instead of simple storage cards with no status information.
