It looks like Seagate on the new 2.5" thin HDDs have gone to using a glass substrate on the platters. Nasty head crash in, and I can see through the platter. See image.

I've not yet seen enough of these in to conclude whether the platter gets damaged a large proportion of the time after head failure. How have people found working on these?

Most(all?) 2.5" drives have glass platters

I thought the previous generation of actual Seagate manufactured 2.5" HDDs (i.e. Momentus, not Samsung M8) did not use glass. I don't ever recall seeing similar type of damage in Desaru series or similar? Or whether the top coating on these modern drives is much thinner than it used to be? Regardless, the ST1000LM035 are starting to come in now, and I wondered how people are finding they react, whether there is a higher than normal proportion of platter damaged HDDs?

Does it look like a head swap from a donor could be done on these drives?

If the platter is not damaged like the one on the phote then yes.

If the platter is damaged like shown then .... game over.

As long as the platters are "intact" then head swap is possible.

Ok, thanks. I was wondering because I have seen on the WD "slim" drives they are
doing platter swap to working drive vs. head swap.

What you've seen was probably amateur videos by people who have no clue what they are doing. This comprises 99% of what you'll find on youtube.

Head replacement is always favored over platter swap unless it has a seized bearing or failed motor that you can't get to spin.
