External Drives "Read Only" on Reboot

[ehmjay]

Every time I reboot my computer my external drives are all set to "read only". I have to eject them, and remount them and things are then fine again, but this is an annoying step and the fact that a reboot is causing them to switch to read-only is having me worried.

Anyone else have this problem/know of a solution?

I've been trying to figure it out over at the official apple forums but we're not getting anywhere... the thread is here:

What filesystem are they formatted using?

Journaled, or whatever the mac standard is.

One of your programs or settings is causing that to happen each time you restart the computer. Do you have Firewall turned on? That can cause permission changes like this. Little Snitch? File Guard?

i do have little snitch, though I don't know why it would cause a problem all of a sudden.
