Every week or so my database decides to corrupt itself and give the error message "BLOB has been modified".

Environment; stream read and writes to TBLOBFIELD objects in a Paradox 7 database...

Anyone know how to avoid this since it corrupts the whole database it's pretty critical.....

Upgrade the BDE. This is most probably because you have the BDE version(don't remember the numbers) which eventually always did corrupt local database tables.

Answer is incorrect.
Already installed latest BDE files from ftp.borland.com.
Problem persists.

Are you using DBISaveChanges in the AfterPost event of each database?  Alternatively you can change the application OnIdle event to flush the changes to disk.

I had this kind of corruption anytime the machine or program would crash for some reason.
