Re: If a disk is mounted read only is it possible to corrupt it?

If I mount *all* of my partitions as read only (ignoring the problems of needing to write log files, etc. for now) and then cut the power to the server, is there any chance of corrupting the disk? It seems that FreeBSD wouldn't do it, but would the disk itself do it? That depends on the disk you're using. If you have problem with your power supply, you should better think 'bout an uninterruptable power supply.

Corruption need not necessarily be s/w based. If your reader/writer is screwed up, it might still corrupt it.
