Device configuration overlay (DCO) is a hidden area on many of today's hard disk drives (HDDs). Usually when information is stored in either the DCO or host protected area (HPA), it is not accessible by the BIOS (or UEFI), OS, or the user. However, certain tools can be used to modify the HPA or DCO.
In this case, one must use software utilities (see below) that use READ NATIVE MAX ADDRESS and SET MAX ADDRESS to change the drive's reported size back to its native size, and avoid using the external enclosure again with the affected drive. Some rootkits hide in the HPA to avoid being detected by anti-rootkit and antivirus software. [2]
The application of a Dynamic Drive Overlay (DDO), as licensed to Samsung Corporation for example, by Kroll Ontrack's version in their Disk Manager program is for the installation of various hard drives (Ultra/Super IDE/Parallel ATA) in computers that have older BIOS chips that do not recognize hard disk drives larger than 137.4 Gigabytes.

The Japanese version of the Windows 95 SETUP program supports a special option /AT to enforce that Windows will be on drive C:. Some versions of DOS do not assign the drive letter, beginning with C:, to the first active primary partition recognized upon the first physical hard disk, but on the first primary partition recognized of the first ...
However, S.M.A.R.T. parameters alone may not be useful for predicting individual drive failures. [16] While several S.M.A.R.T. parameters affect failure probability, a large fraction of failed drives do not produce predictive S.M.A.R.T. parameters. [16] Unpredictable breakdown may occur at any time in normal use, with potential loss of all data.
If your third-party email app is having issues connecting, sending, or receiving emails, you may need to reconfigure your account or update the app. Use these steps to identify and fix the source of the problem.
A new study suggests that a diet filled with protein and fiber may be the most effective for weight loss. Here's what a dietitian wants you to know.
The software is designed to find, test, diagnose and repair hard disk drives, reveal problems, display health and avoid failures by using S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) function of hard disk drives. [34] [35] [36] The detected information can be saved to file in formats such as HTML, text, or XML. [37] [38] [39]
