ADRC Hard Disk Checker is a free disk utility that checks the health of your hard drive. It scans your hard disk for bad sectors and alerts you if the media does not have optimum usability. With this software, the user can either choose to scan a specific partition or an entire hard drive.

ADRC Hard Disk Checker can also be used to check the health or bad sectors of other types of data media, such as floppy disks, flash drives, magnetic tape etc.

The hard disk checker is easy to use and would be suitable for users of any technical background or level but is also useful even for computer experts. This software complements the ADRC Data Recovery Tools which allow the user to recover files from a hard disk with bad sector.

How to


Scan an entire hard disk drive

From the drop-down menu near the top, select "PHYSICALDRIVEX" where X is 0, 1, 2 etc. that corresponds to your physical disks. If you have more than one hard disk drive, the second drive will be displayed as "PHYSICALDRIVE1" and the third drive will be displayed as "PHYSICALDRIVE2".

  • Click the "Check" button to start scanning.
  • If there is an error on your hard disk, the software will alert the user and he may choose to stop or to continue the scan.


Scan an individual drive / partition

From the drop-down menu near the top, select the media / partition drive letter. E.g. "C:\"
Click the "Check" button to start scanning.

If there is an error on your hard disk, the software will alert the user and the user may choose to stop or to continue the scan. If the disk scan is stopped, in the next run, the program will remember the checkpoint position and you could select to start from the previously stopped position or start from beginning again.
This feature is useful as such disk scan is resource intensive and the user may want to interrupt the scan to continue working before coming back to the scan disk again.

Very often, the bad sectors of disk media could be "masked" or "hidden" from the operating system after a full disk format and data disk may appear perfectly normal as long as the bad area is never "visited". The presence of bad sectors on disk need not be a strong reason for imminent failure. However, we feel that the costs of hard disks are cheap and you may not want to continue using the disks with hidden bad sectors. After all, a perfectly good disk should have no bad sectors to start with.


Quick check feature

Quick check feature allows the user to briefly scan the date media which takes a fraction of time of a full scan. It is able to detect problems if the bad sectors are in significant quantity.

Near the bottom of the interface is a check-box labeled as "Quick Check".
Check the box before doing a scan to do a quick check.


Log Exporting

Log export allows the user to save the detailed result of a scan into a text file.

To export the log, click the "Export" button after completing a scan.
