A week ago my home server crashed. The server refused to start after reboot attempts. After connecting a monitor to it I found out that the reason was the dead hard drive. The disk was a 750GB Samsung Spinpoint F1 bought about 5-6 years ago. It had been powered on for total of 30000 hours according to the S.M.A.R.T monitoring. It was possible to power on the disk and read the S.M.A.R.T values but any attempt to mount the data partition would cause the disk to make loud clicking noise.
This caused the loss of all my backups for the last month. Test environments of some projects were also taken down. I have been busy restoring them.
The new hard drive is 1TB Western Digital Black. The manufacturer gives it a 5-year warranty.
