(actual diagnostic message from the on-board JMicron RAID controller on an Asus P5B-V motherboard)
I learned a few lessons on Monday:
- Lesson the first
- If you have a RAID 1 array, and one of the drives suddenly drops out of it, do not simply assume it was a software error and reassign it, or you will be very unhappy a few months later when that drive really fails.
- Lesson the second
- Take off that wool sweater before you open the case to fiddle with those damn SATA connectors to make sure that it really is a failed drive and not just a loose connector.
- Lesson the third
- It is perfectly possible to remove a Socket 940 CPU without first unlatching the socket. All you need to do is 1) install the CPU, apply heat transfer compound and install the heat sink; 2) wait a couple of years for the heat transfer compound to dry out; 3) apply force to the heat sink in an attempt to remove it in order to move the CPU from the board you just fritzed to a spare board you happen to have lying around; 4) observe that the heat transfer compound has practically welded the CPU to the heat sink, so the CPU was pulled out of its socket when you removed the heat sink.
- Lesson the fourth
- However, it is not possible to insert a CPU without first unlatching the socket (at least, I didn’t dare try too hard).
- Lesson the fifth
- Socket 940 motherboards and CPUs aren’t commonly available these days.
- Lesson the sixth
- Luckily, Socket 775 motherboards and CPUs are (relatively) cheap and plentiful.
