One of our customers called us with a VERY slow laptop. We test the hard disk and it's only at 9% health. The lowest we have ever seen one.
Previous low was 11%.
We set about trying to clone the drive to a new one.
Three days later and huge amounts of I/O errors, the process completed. Drive now at just 2% health. We refitted the new hard disk expecting the worst. What we got was a surprise. First boot, stright into Windows. No errors. A full file scan to be sure and now the laptop is up and running and blissfully happy. No, wait..... that last part about blissfully happy. Well, that's us.
