Having come home yesterday to a dead UPS, I was hoping for a better day. Today I have been installing VMware Server and had one or two small issues, a quick tail on the messages log to check the status of things and I find this:

Aug 30 22:03:16 vm smartd[2477]: Device: /dev/sda, SMART Failure: LOGICAL UNIT FAILURE PREDICTION THRESHOLD EXCEEDED

Arr, Now, I know SMART is not always right, but now I know I really should replace that drive, I had been thinking about it. Off to the shops I think!
