Manual Ways to Repair Access Database Files
Apart from the inbuilt utility tool, you have other options as well to fix database corruption. So, let’s see what are other solutions available for Access database repair.
Way 1- Restore from Updated Backup
If you have kept an updated, valid, and proper backup of your Access database, in that case, you can use the healthy backup for restoring your database instead of repairing it.
The complete steps are here:
- Launch File Explorer, and choose the folder that contains the backup copy.
- Select & copy the backup file.
- Paste the copied file to the same place where the corrupted database file is saved.
- Once prompted, replace the existing database file with a backup copy.
Way 2- Repair the Access Database using JetComp.exe
MS Access offers a freeware utility JetComp.exe, in order to repair mdb/accdb file created with Microsoft Jet database engine 3.x.
Note: Before executing JetComp.exe, you need to rename the Master Client database to PROB.mdb.
Now you can easily run JetComp.exe from the Montel Application/support directory. Here are the following steps to repair database using JetComp.exe:
Step 1: Firstly you need to enter the full path (MonTel Datadirectory/CLIENTDB) and name PROB.mdb in Database to Compact From (Source): field.
Step 2: You need to enter the full path (MonTel Datadirectory/CLIENTDB) and full name ([ClientDB] section ClientDatabaseName + “.MDB”) that is likely to be CLIENT32.MDB.
Note: don’t make modifications in any other fields.
Step 3: At last tap to the Compact option.
- Once you get success, allow other users also to MonTel.
- But if in case you don’t get the success, don’t forget to restore CLIENT32.MDB (or whatever it’s named) from your backup copy. After this, you can delete PROB.mdb.
Way 3- Import the Corrupt Access Database into a New One
Another most opted solution to repair the Access Database is importing data from corrupt Access Database to the new one. So, here are the steps that you need to follow.
Step 1: At first, open the Microsoft Access on your PC.
Step 2: on the right-hand side pane, tap on the option of “create new database” files. Assign a name for the file and choose the location. Tap to the Create option to create the new database.
Step 3: This will make a database file and open it up in the Microsoft Access program. Click the external data at the top.
Step 4: To import the Access database tap to the Access option.
Step 5: You will see a get external data Access Database window opened on your screen.
On this opened window tap to the Browse option to make a selection for the file that you want to import.
Step 6: On the opened dialog box of File Open, browse access database files and select it by clicking. Tap to the Open option to make confirmation for the selected items.
Step 7: In the edit box, you can easily take a look over the selected files. For further continuing of the process tap to the OK option.

Step 9: Now you will successfully import all selected objects.
Step 10: If you want to save the above performed import steps for future work then check the Save import steps box. At last tap to the Close option.
Way 4- Deletion Of The .ldb/.laccdb File
.ldb/.laccdb file is mainly used to find which records have been locked in a shared database and by whom. If the database is open for shared usage then the .ldb/.laccdb file automatically gets created having the same name as that of the corresponding database (.mdb/.accdb).
Delete the .ldb/.laccdb file if it is present but before that close the corresponding .mdb/.accdb file.
How about an example,
Suppose, that you open the sample database Northwind.mdb for shared use in C:\Msoffice\Access folder, then it will automatically create a file named Northwind.ldb in the same folder. Well, this .ldb file automatically gets deleted when the last user quits the database with these two exceptions:
- When the last user doesn’t have permission for folder deletion, having .mdb file
- Or when the database is corrupted
This .ldb file has the complete list of users who all have opened the Database.
Way 5- Remove Compiled VBA Codes from Database
Even after trying the above manuals, if the database corruption issue persists, you can use the below command line switch from the Microsoft:
C:\Program Files\Microsoft Office\Office\MsAccess.exe /decompile C:\DatabasePath\FileName.mdb
Please Note: You have to change the above path for MsAccess.exe if you have installed it in the different location.
