2020-02-12T08:06:43:230-06:00 140114698520320 I000101F4: Failed to read data from the disk.
Failed to read from sector '-966,367,643' of hard disk '3'. User response: Cancel
Cause
The warning appears because the VM disk specified in the error message has errors.
Solution
- Review the error message to locate the affected disk. The error appeared at an attempt to read this disk.
- Move data from the affected disk to a new one: add a new disk to the VM and copy data onto it, then delete the affected disk.
- If the disk cannot be replaced (it is a system disk), create a backup by the Agent installed within the guest operating system of the VM (Agent for Windows or Agent for Linux). Restore this backup to a new VM, then start backing up this new VM instead of continuing backups of the old VM.
- If the issue persists with the new VM, contact Acronis support for further investigation.
