..but Windows doesn't tell you about it.
Whenever I boot my laptop with Linux (using my USB flash drive) I get this interesting warning message on my desktop:
I suppose the laptop's internal hard drive is due to fail any time now, taking all my work with it. (Fortunately I save all my work on our file server, and keep my email on the mail server, so I'm not likely to lose much of anything.)
But thanks to Linux, I do know that the hard drive is reporting health problems. So if this were my own system, I'd make sure my backups were up to date, and start shopping around for a replacement hard drive.
I find it interesting that I've never seen a similar hard drive warning message under Windows. I've discussed before that I can only compare the default behaviour between Windows and Linux. Maybe Windows saves this warning to a log file, instead of showing it to me? I wouldn't know. I also wouldn't know that my laptop's hard drive is going to die soon.
I think a real strength behind Linux, and any open source software system, is that it's driven by real people - not corporate entities. As a result, Linux and other open source software works in a way useful to real people. It just makes sense that a desktop environment would alert me when my hard drive is due to fail. Thanks!
Similarly, my wife's laptop - also running Linux - is over 5 years old now. The battery no longer holds a full charge anymore. So when she logs in, Linux warns her that her battery may be broken. Except I think she has the option to disable the battery level warning, but prefers not to. The message tells her what is her maximum battery capacity, and she decided we'll replace the laptop when the battery reaches a certain level. (And that's coming soon.)
