Yeah, I agree, I think they just haven't bothered to test it properly at odd angles. and to be sure, they say "mount vertically or horisontal".|Romeo| wrote:Why ridiculous? If it needs modifications to achieve (or even just testing to validate that it won't have negative effects). For instance, WD might think why should they waste money on validating this when we could spend the time on making the drive faster, whereas Seagate might think that this is a more important feature (maybe an OEM who wanted to mount a drive at 45 degrees) so they make sure that it can do that.Splinter wrote:It seems a little ridiculous to me that some brands of HDs could be mounted obliquely and others couldn't.
I think what's more realistic is that some manufacturors are just trying to limit their liability.
There may never be a general consensus. Some of us have attempted to show that the concerns listed in this thread are not a significant risk. If there are other factors, no one has brought them to our attention. And if anything you've read here doesn't make sense, voice your question in a specific manner and it will likely be answered.timmytimmytimmy wrote:Since my other thread was locked..I've read through this thread before, but there seems to be no general consensus??
As for the poster asking about the temps, those are fine. Mine run at 45-50 degrees idle:D

Years ago,I did testing at Seagate,drives were "right side up" but drives are much more sophisticated now (and we just tested that they worked,not MTBF. I have used drives right side up,upside down and sideways-have not seen much difference.mathias wrote:Wouldn't that mean that only vertical mounting is optimal? I wonder what orientation is used when testing to determine MTBF figures. I doubt it would be possible to just ask manufacturers and get an honest answer.kevinc wrote: Think of a drive in the horizontal orientation. The arm above the disc has a worst-case effect of gravity pulling the arm towards the disc, and the arm below the disc has a worst-case effect of gravity pulling the arm away from the disc.
Thanks for the reply. I have a WD 2500KS SataII HD. I think that's FDB.whiic wrote:"Would it be a problem to change the HD from horizontal to vertical after a longer period?"
Badly worn-out ball-bearings might no like that, but for drives with fluid dynamic bearings, it shouldn't be a problem as they don't wear out that way. (Bearing fluid may lose it's properties or evaporate under extreme condition such as high humidity or temperature, but it wouldn't develop excessive free play like BBs that make physical contact with metallic or ceramic bearing balls.)
I have a ~4GB Maxtor mounted upside down since when it was first installed by HP and a Seagate U5 that has been runnin for years vertically, IDE connector pointing straight down. Not odd angles but not very common either. They operate in other orientations as well, even though they are getting old and have ball-bearings.
