Known issues with DaRT 8.1
Disk Commander is unable to repair a corrupt master boot record in a physical partition in Windows 8.1
In Windows 8.1, the “Restore the Master Boot Record (MBR) or the header of the GUID Partition Table (GPT)” option in Disk Commander is unable to repair a corrupt master boot record in a physical partition, and therefore is unable to boot the client computer.
Workaround: Start Startup Repair, click Troubleshoot, click Advanced options, and then click Start repair.
Multiple instances of Disk Wipe that target the same drive cause all instances except the last one to report a failure
If you start multiple instances of Disk Wipe, and then try to wipe the same drive by using two separate Disk Wipe instances, all instances except the last one report a failure to wipe the drive.
Disk Wipe may not clear all data on solid-state drives that have flash memory
If you use Disk Wipe to clear data on a solid-state drive (SSD) that has flash memory, all of the data may not be erased. This issue occurs because the SSD firmware controls the physical location of writes while Disk Wipe is running.
System restore fails when you run Locksmith Wizard or Registry Editor
If you run Locksmith Wizard, Registry Editor, and possibly other tools, System Restore fails.
Workaround: Close and restart DaRT, and then start System Restore.
System File Checker (SFC) Scan fails to run after you start and close Locksmith Wizard or Computer Management
If you start and then close Locksmith Wizard or tools in Computer Management, System File Checker fails to run.
Workaround: Close and restart DaRT, and then start System File Checker.
If you install DaRT 8.1 by using the command line to run the Windows Installer (.msi), and the Windows Assessment and Deployment Kit (Windows ADK) has not been installed, the DaRT installation should fail. Currently, the DaRT 8.1 installer installs all components except the DaRT recovery image.
Windows Defender cannot start after Locksmith Wizard, Registry Editor, Crash Analyzer, and Computer Management are started
Windows Defender does not start if you have already started Locksmith Wizard, Registry Editor, Crash Analyzer, and Computer Management.
Workaround: Close and restart DaRT, and then start Windows Defender.
Windows Defender may be slow to start
Windows Defender sometimes takes a few minutes to start. The progress bar indicates the current loading status.
