To repair Access database, you should try Compact and Repair utility, a built-in tool in Microsoft Access. JetComp.exe utility is also provided by Microsoft, and can repair Access database. You can also try to import data from corrupt database into a new database. Refer to this blog post to know how to repair Access database manually: Repair Access Database with Compact and Repair Utility | N. Sem's Blog[/url]
You can also try a professional Access database recovery or repair tool but only if the manual tricks fail or don't work. Search best professional solutions on Google. I would strongly recommend you to download free demo version first before purchasing the software.
Thanks.

Back in '90s I developed and maintained FoxPro applications, which was then using the same client / file server model perpetuated by MS Access today. Things like network bandwidth, concurrency, and data corruption were daily (not just occasional) struggles.
I found a TechRepublic article that summarizes best practices for avoiding MS Access database file corruption.
#1: Split large databases into separate files
#2: Store temporary tables in a separate database file
#3: Don't use memo fields
#4: Don't store picture files
#5: Create temporary tables to speed up queries
#6: Be careful with wireless networks (WiFi)
#7: Be careful with WAN connections
#8: Don't put Mac and Windows users on the same network
#9: Troubleshoot network hardware
#10: Check the server's configuration

I would try the following.
1 Make a copy of the original, and try to open that (That is the 'live one')
2) If you can't open that on either, you may be able to get a 'previous version' - Right click the file, and select properties, there is a previous versions tab. - If there are any, save it to a new location.
3) Create a new database and see if you can import any objects from the bad one:- I've never had any success with that, but some have.
4) Restore one from your system backups, and re-input any data since the backup was taken
5) If none of that works, then you have to purchase a professional Acc MDB Repair tool in order to fetch inaccessible data.

The "Unrecognized Database Format" error often signifies corruption in your Access database files (MDB/ACCDB). Instead of immediately seeking a third-party recovery tool, consider using some manual techniques to attempt recovery. If these methods do not succeed, then a commercial tool may be necessary for restoring your database.
Manual Techniques for Repairing Corrupt Access Database Files
Utilize the Compact and Repair Tool
Launch Microsoft Access without opening the corrupt database. Navigate to File > Database Tools > Compact and Repair Database. Select the corrupt database file and click OK to initiate the repair process.
Import Data into a New Database
Open Microsoft Access and create a new blank database. Go to External Data > Import & Link > Access, browse for the corrupted file, and import all database objects.
If these manual approaches do not resolve the issue, consider using a professional recovery tool such as DRS Softech Access Database Recovery. This tool is designed to efficiently restore MDB/ACCDB files, ensuring a quick recovery of all database components, including tables, queries, forms, and relationships.

As much as one appreciates your enthusiasm replying to a 10-year-old topic, April Fool's Day might not be the right time.
On your point on recovering a corrupt Access Database, such tips are version specific, i.e. back in the days, one used to take a fresh file header and paste it on the rubbish before the object definitions......
