I think logging is not a main reason for damaging disks.
I have enabled mail_log plugin since march 2011 without problems and it helps me very often in such cases.

Could it be that some other person is downloading the mail via pop3 and then the client is deleting it from the server?
This happens to me sometimes when a customer is accessing his account with a new client but forgot to disable the same account on his old PC.
So it happens, that the old pc downloads all new mails, delete it then and the customer never see new mails on his new client.
