Exchange 2007 SP1, Information Store, Storage Groups and Corruption:

Dear Experts, we're running Exchange 2007 SP1. Last week, our service collapsed when one of the storage groups encountered a corruption. We were unable to identify which storage group was at fault, so had to dismount all of them, then mount them one at a time until the service fell over again.

(We had problems with restoring and merging the restored Storage Group, the logfiles and the dialtone database we created, but they're for a separate question..)

Why would a corruption on one storage group bring the whole Exchange Service down? How could we prevent such a catastrophic failure from recurring?

Surely if one S/G is failing it should not cause the whole service to die?

Is there a better way(there must be, surely ?) to identify the failing storage group, so that it can be avoided in order to mount the intact groups.

Appreciate your advice!
