Question

How can I save my data when "Fatal error SDE201: Hard disk read failure" appeared after uninstall of Sophos SafeGuard Disk Encryption via the Emergency Tools?

Answer

First of all, please make sure that the emergency tools were started before the PBA and not via post-PBA boot.

If the emergency tools were booted before the PBA and SDE201 appears during emergency uninstallation, the hard disk has certainly taken some serious damage (defective sectors). Because of this hardware failure, Sophos SafeGuard Disk Encryption is unable to unencrypt the harddrive.

The error message means: "SDE201: Hard disk read failure - Direct reading of the disk not possible or only partially possible"


Please save all your data, if possible, and check the harddrive for hard disk failures.

In some cases, data on the harddrive can only be recovered by a professional data recovery center.
