QuickBooks Unable To Commit File Write Operation to Disk


QuickBooks designed and developed by Intuit smoothly handles the accounting tasks of the business. But as it is a known fact that software and issues go hand in hand, QuickBooks users face at times face problems when they are not able to backup. It displays a message – “Unable to Commit File Write Operation to Disk.”

This is a frequent problem faced by QuickBooks users. The reasons for being unable to back up the QuickBooks file are as follows:

  • The Authentication Stage of the Backup process fails
  • Backup command crashes
  • Regular backups can be made, but portable files cannot be created

The problem may also be related to the media, but the usual cause is data corruption. Below are DIY fixes recommended by Intuit:

  • Rebuild your company data (File / Utilities / Rebuild Data) and retry. The rebuild command can often fix things in the file that prevents a verified backup from being created.
  • Attempt to backup a local hard drive, instead of to a network server, cloud drive, external drive, or USB drive. All those kinds of drives, besides a local hard drive, could have connectivity or speed issues that would prevent a successful backup from being made.
Note : Big companies using the Enterprise Suite of QB or using cloud hosting for managing their accounting software can get the help from QuickBooks Enterprise Support Number.


This kind of error occurs when QuickBooks has been re-installed or updated, and restricts permission required for CommitCRM to carry out the invoicing and import operations that the CommitCRM QuickBooks Link offers our community. The rectification of this error comprises configuring QuickBooks to grant permission to CommitCRM.

To carry out this process you need to have the QuickBooks Admin user login into the company file. QuickBooks integrated applications need the admin user credentials to allow an approach to the company file the first time the utility is run.

This helps the program to have the correct permissions to read and write transactional data to the QuickBooks data file.

  • Open QuickBooks as the admin user
  • Select Edit -> Preferences -> Click on the icon for Integrated Applications
  • Select the application CommitCRM from the panel
  • Tick the application to grant it permission to QuickBooks data
  • • Re-open CommitCRM and retry
