Was my hard drive case enough to protect my external hard drive?

First post on these alternative sites so forgive any mistakes. My external hard drive (a small travel one) was enclosed in a padded hard-shell case like this one but I’m still worried. When I went on vacation, I had the hard drive in a bag that I was dragging down the (carpeted) stairs. I don’t know if the protective case was intended to shock absorb something like that and had I realized sooner that the HDD was in the bag, I would’ve packed it away with the laptop instead.

Should I replace the drive before something happens or do those cases shock absorb?
