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.
Maxtor Maxline Pro 500 ( 500gb sata) powered on 600 times and 38,443 hours temperature about 42C
so 4.39years on time. Its in my Dell poweredge 700 Server. on 24/7 Clean it every 2 months
Maxtor FTW
Cagliostro that’s a lot for a year I think ;)
It don’t works with my 2×250 sata raid :(
Open the program
Goto > Function > Advanced Feature > Advanced Disk Search
sees my SATA RAID now
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)
Duh… downloading from their site is failing…:

My Segate 80GB HDD has reached historical mark of 10,000 and still it is running without any problem.

i have 19,000 hours on my seatgate 80gb, still good for me
in my 24/7 server:
120GB Western Digital: on 33588 hours, 237 power cycles
160GB Seagate : on 16054 hours, 409 power cycles
500GB Hitachi Deskstar: on 19034 hours, 128 power cycles
500GB Western Digital : on 3215 hours, 30 power cycles
all look good, plan to eventually replace the seagate mainly because i got it used and I dont like how seagates use some of the smart data (ie raw read error rates being a bogus value) – other than that, drives used daily – all temps average between 32-37 deg C – i think anything over 40 is a no no
I got 3 hdd! All WD.
2 x 160gb and one 1Tb
In order:
28159 hours
13503 hours
7210 hours < 1Tb
Non stop seeding!!!!! :)
2TB WD Green: 10201 hours, 168 power cycles
1.5TB Seagate CC1J: 18342 hours, 528 power cycles
1.5TB Seagate CC1H: 15171 hours, 352 power cycles
Exellent program worked out how many hours my computer has done since I had it ( drive is origional fitment)
Drive is Fujitsu MHT2080AT in Fujitsu Amilo D 1840W Approx 7yrs old.
Power on 2203 , hours 15,400 works out at about 2,500 a year as its had hardly any use for last 18months. Now It cost more that alot of laptops did at the time but now I can see why as the only thing I have changed is added 512Mb memory!
