I mounted 2 hard drives right pn top of one another on top of an optical disk reader as a mean of managing space
They have double sided tape seperating each other
Is this a problematic settup or is it fine.
Sometimes i hear a humming noise which im lead to believe it is the hard drive ( like a vibration) but other than that it SEEMS fine

Everyone seems to have covered the heat aspect risk of doing this, but I don't see anyone mentioning vibration. Vibration from the two disks being connected and on top of a running DVD drive could cause the disks to wear quickly and even fail. Its been documented everywhere but here is a source: http://www.techrepublic.com/blog/10-things/10-ways-to-keep-hard-drives-from-failing/

Unless you don't care about the data on the drives then I wouldn't do it.

I'd avoid putting hard drive mounted so closely to each other. More information on this thread:

Some drives depending on make and RPM can dispense quite a bit of heat under heavily load. I'd put time in with a mounting bracket somewhere else. There a plenty of variants. But in front of the computer with a fan on light setting. You can put a 3,5" drive in a 5.23" bay, or a 2.5" in a 3.5" bay.

This is something to consider when mounting drives. I generally put any performance drives on the top 3.5" bay and go with the NAS- or green drives in the bottom of the array.

Yes. Vibration kills hard drives more than heat. Take a look at some of the reports Backblaze puts out about their drive failures from their data center. https://www.backblaze.com/blog/enterprise-drive-reliability/

Not sure if a laptop drive would cause as much vibration as a normal sized drive but it would certainly be at the same level of risk for failure.
