How to Fix VolSnap 36 Error User Imposed Limit – Volume Snapshot

VolSnap 36 event ID may show up as error:

Volume Snapshot Driver, Diff Area health issues


Event ID 36  
 Source volsnap
 The shadow copies of volume C: were aborted because the shadow copy storage could not grow due to user imposed limit

or a related message.

Basically VolSnap 36 is an error event that signals an issue with the diff area being used by VSS.

It could be

  1. a low limit for the diff area, see
  2. a disk I/O issue
  3. a bad sector on disk: use chkdsk X: /b to check for bad blocks (may require a reboot)
  4. system load is too high for the diff area to grow fast enough
  5. a corrupt file system issue. Use Chkdsk with /r option, better use /b to also check for bad sectors

The most common cause is #1. Use the solution in the article linked above; however, checking the other potentialities may also be a good idea if the disk hasn’t been checked in a while.
