The 2TB data drive in the Lenovo ThinkCentre Edge is running low, so I thought I'd add a new 3TB drive in, robocopy the contents over, swap the drive letters, then I'll have an extra 2TB partition that I can repurpose for some other use. Simple, right? Except when I opened up the case, I found this funny layout which prevents a third drive from being added. So instead of adding the third drive, I now have to replace/swap HDD2 and HDD3 instead.
On my pc with 7 HDDs, I had the 7th one facing upside down. Died on me after 1 year. Had to face to upside down because the cable just felt more comfortable at that orientation. But why did it die facing upside down so soon? As for your case, time to get a new chassis.
I think I need more than that, lol. This is an old 2nd gen i7 on a motherboard that doesn't even have USB3 at all...
Technically, HDDs can work upside down without any issues. In fact, most notebook HDDs are installed upside down.
Then I guess mine was just bad luck. Anyway... get an Intel mobo that can support 10 HDDs! My friend bought one and an i7 for around 1.5k. He's an Intel employee anyway, it's a much discounted price I guess. He said i5 and i7, difference not much, so he got the i7 instead. I'm still with my Q9650.
