  • In the Event Viewer of the source physical machine, you see events similar to:

    Event ID: 14
    Source: VolSnap
    Type: Error
    Description The shadow copies of volume <volume> were aborted because of an IO failure on volume <volume>.

    Event ID: 35
    Source: dmio
    Type: Warning
    Description dmio: Disk Harddisk 1 block 32391 (mountpoint <drive letter>:); Uncorrectable read error


This issue may occur if the hard disk contains hard bad blocks that cannot be fixed using the chkdsk command or if the disks need a defragmentation.


To resolve this issue:
  • Analyze and defragment the physical hard disk using Disk Defragmenter.
  • If the hard disk has hard bad blocks, contact the hardware vendor of the physical server for further assistance.
