Would Velcroing both to the optical drive slots work?

I lost them.

I took out the Hard Drive cage to install new fans then lost the cage. I gave the PC somone to build for me as I was busy. They contacted me telling me there is no where to put the HDD + SSD besides the cage. I suggested velcroing it. They said the vibrations would damage the drives. Is this true? If so, without getting a new cage, where should I put them.
