But when we were forced to reindex the Foxpro system would be shut down for an hour or two, which meant everyone in the company sat. So we decided to do it on off hours on the weekend.

OK. Probably not data corruption then and you're doing the right thing to build the indexes. Another thought just came to mind. When VFP terminates abnormally, it leaves temp files around. Are you cleaning these up? My experience shows that these temp files sitting around can cause more problems.
