| 405869 | 2005-11-20 19:49:00 | Hi there I would just like to ask is it really true that HDD should only operate in its original positions, eg flate with the sticker side facing up and the disk&chip side facing the bottom. Cause I've heard that if it operates in any other position eg 90º to one side or complete 180º or even 45º to one side, after a while, the HDD would eventually break, due to the lens. I mean if thats so, wont that happen to Ipods and any other HDD base mp3 players? or self-made HDD base mp3 players? Thanks |

| 405870 | 2005-11-20 19:56:00 | To the best of my knowledge, as long as the hard drive is either flat, or at 90 degrees, then it will be fine. I can't remember exactly why though. | somebody (208) | ||
| 405871 | 2005-11-20 20:23:00 | I pulled the side off my computer yesterday, To find I had left the HD hanging by the powercord last time I had been in there. Hasn't missed a beat.... |

I think the old hard drives (MFM/RLL interface) needed to be positioned horizontal because of the centrifugal forces placed on the read/write heads from the disk spinning, but that is not a problem these days. |

| 405874 | 2005-11-20 21:11:00 | There is no lens. :D The problem with earlier drives was that the track positions were mechanically defined by the steps of a stepping motor which moved the heads. With time, gravity and wear meant that if the drive was put in a different orientation after it had been formatted (which actually wrote all tracks) the heads would be slightly out of position. (Floppies still use mechanical track postioning, except for the shortlived LS120, which used a laser to track marks put on the disks in the factory). Nowadays, with servo tracks written in the factory, the heads are kept aligned by the "voice-coil actuator". From being a desirabl;e feature, it became essential as the track density increased. (80 track floppies use 96 tpi, which is pretty well the limit for mechanical). So mount the disk drive at any angle. |
