Two months ago I got a new Dell Inspiron laptop to use for my work. I have been very pleased with the computer which is quite fast and has a good keyboard and a very nice screen. However this afternoon I switched it on to do a bit of work and was typing away when the hard drive started making a noise like a cat with indigestion - which anyone who has ever done tech support will recognize as the sound of a hard drive attempting to read a bad sector.
Windows froze, there was no way out but to long-press the power switch, losing the work I had been doing. On start-up, Windows insisted on doing a disk check and printed up a lot of messages that appeared to be to do with errors on the hard drive. Eventually I was able to restart, Windows booted up and it seems to be working normally again. But my confidence in the system's reliability has taken a blow. In my experience hard drives don't malfunction once and then run perfectly for ever after. But there's no sign of any fault now, so I have little option but to wait until the next time it starts making funny noises. :(
