Can you tell me how many hours your hard disk or Solid State Disk has been running and how many times it has been powered on since you started using it in your computer ? My Samsung 1 TB hard drive was powered on 106 times and active for 814 hours since I build my new computer a few months ago.
How I know that ? I looked it up in the software Crystal Disk Info. This software basically displays all kind of information about hard drives and Solid State Disks and two that are not displayed in every other of that type are the two I mentioned above.
It does display all the usual information as well. Begins with the hard disk temperature, serial number, transfer mode, drive letters and supported features among other parameters. Two of the aforementioned parameters are worth a closer look if you are experiencing crashes or slow downs.

The temperature of the hard drive can be a cause for system crashes. It if goes to high it can lead to data loss and errors. The transfer mode can be interesting if you think that your hard drive is not as fast as it should be. Check the supported transfer modes of your drive and compare them to the one that is currently being used for it. It might very well be that it’s not the fastest available.
Crystal Disk Info is a portable application that is compatible to Windows 2000, XP, Vista and Windows Server 2003 / 2008.

My notebook hard disk was powered on 886 times and active 3615h. As it’s about a year old that’s more than i thought.
Cagliostro that’s a lot for a year I think ;)
It don’t works with my 2×250 sata raid :(
3,8 years on my side.
28781 hours for mine. Too lazy to look for purchase date, around 3+ years.
>23C
Are you keeping yours in the freezer?.. :)

Dumb IT mythology. I hadn’t ever seen HDD dead from thermal damage alone. You must practically fry it by running at 60+C to achieve overheat. Anything up to 50C is pretty comfortable temperature for HDD and it’s hard to get more in average computer case.
Rarst it was shortly after system boot :)
Don’t need no steenkin software to tell me :)
My harddrives are 24/7. That’s also why I no longer buy Western Digitals. They just plain sucks – built to crash.
My Raptor has done 8451 hours.
interesting that my greenpower drive run’s a degree hotter than my raptor, but quite good when you factor that the green power is a 4 platter 1Tb drive the Raptor is of course single platter 36Gb drive.
My my…
2248 hours and 284 power ups for about 5 months, I need to use it less ???
I’ve tested it on 3 PCs and got always strange results, like this one… (link to image)
That’s damn hot Litschi :)
for me too, strange result for Power on Hours : 64?hours
but it saids “caution” for my first hard drive, and I know that it’s true (power on count : 2549)
