Subj. The HDD caddy in mine is cracked and I can't find a replacement anywhere. I've tried using plastic cement (acetone-based glue that's supposed to chemically "weld" pieces together), but acetone doesn't seem to have any effect on the plastic that 701C's HDD caddy is made of. Hence the question in subj: what is the chemistry of that plastic, what can bond it well enough that it can withstand the tensile stress that comes with trying to pull the hard drive assembly out of the laptop?

It's made out of wet cardboard and you can use super glue.

Hmm, after double-checking looks like I misremembered and the problem with cyanoacrylates is not low tensile strength but low shear strength... Still, super glue tends to be more on the brittle side, are there any other suggestions that may be better than super glue?

JB Weld, UHU Kraft or UHU Power.

Super glue didn't work, gets detached at the glue-plastic border. Trying out JB Weld next.

It's made of paper plates and flex seal

And everytime I see one...I think "that's alotta damage" because even a well preserved one looks like a train-wreck.

Yep!

Those UHU glues I mentioned can even glue Styropor (expandable polystyrene).

Any particular one? There are whole bunch of them, both UHU and JB Weld. I was thinking of trying out this one.

P.S.: Is this the UHU Power you're talking about?

This is my favorite for plastics and most anything else.
Second is this one
I have used various JB Weld ones, mostly for Thinkpad chassis breaks.
