Don't know if anyone else has seen this, but so far we've been batting 1000; every time we've restored a database with a Jumbo dataset, it's "corrupted". Apparently there's a problem with the "chunk header timestamp" when they get restored and the database is inaccessible. many thanks to Tim Joseph from Bradmark who provided us with a DEBUG script that triggers some kind of auto correction of the jumbo files. Tim tells me that the problem is fixed in TurboImage C.07.23 which is still in beta. S/R 1653284398. Our systems are on 5.5 PP6 and PP7. Both encountered the same problem, on EVERY restore (of a database w/jumbo sets). Are we the only lucky ones that have hit this??? I don't recall hearing about it on the list previously? It cost us many hours... -Chris Bartram
