Verify and rebuild your company file
Generally, if your company file is damaged, you want to verify your company file and then rebuild it to correct any data damage. You may need to cycle through the verify-rebuild process more than one to correct all data damage.
The Verify Data utility (Verify) is your primary tool for detecting data damage in your company file. Verify looks at each transaction in your company file and records a message in the Qbwin.log file for any damaged transactions. Verify also detects damaged list items.
While Verify detects many types of data damage, it does not detect all of the damage that might be in your file.
You should run Verify in single user mode.
The Rebuild Data utility (Rebuild) repairs damage in a QuickBooks company file. Rebuild analyzes a company file and attempts to repair or update data found to be in an incorrect state. Run the Verify Data utility if:
You receive error messages when working in QuickBooks
QuickBooks shuts down when you click to save a transaction
Discrepancies appear on reports; that is, invoices or bills that post with a negative value
Deposited payments show up in the Payments to Deposit window
Balance sheet reports are not showing all accounts
Names are missing from lists
Transactions are missing
The company file won't open
Transactions can't be saved
You experience power surges or dropouts, abnormal shutdowns, computer crashes, or "Company file in use, please wait," messages
Note: As part of your company file maintenance routine, be sure you run regular manual backups with full verification and check the Qbwin.log file for error messages.
Run the Rebuild Data utility if:
The message that the Verify Data utility has failed appears
The Verify Data utility returns a b-check error
A QuickBooks Help and Support Knowledge Base article mentions a data rebuild to fix errors
QuickBooks displays payroll forms incorrectly
Note: If it looks like Rebuild froze your computer, move your mouse. If the mouse pointer moves, Rebuild is still working normally
