The 320GB HD I'm replacing is 7.5mm but it's got snap on rubber "rails" on each side that increase the thickness to 9.5 mm and fill in about 1/4" of space on each side of the drive to fill the bay and make a snug fit.
Intel 520 is 9.5mm thick (has plastic spacer screwed onto it).
I slide the Intel 520 into the bay. It goes in but there's 1/4" gap on each side. It needs to rubber side rails to make it fit.
I remove the rubber side rails from the 320HD I am replacing and try and put them on the Intel 520. They won't fit because of the plastic spacer on the Intel 520. No problem. I remove the plastic spacer on the Intel 520 by removing the 4 screws holding the spacer on. I then realize that these same 4 screws also hold the lid on the Intel 520 and I screw the 4 screws back on only to find out that the holes are not deep enough for the screws to go back in! I look in the box. No extra "short" screws to use when converting the drive to a 7.5mm by removing the spacer.
Then I notice writing on the top of the Intel 520 "removing the screws voids the warranty".
The Intel 520 won't work in a Lenovo T420, one of the more common business laptops.
What would including the shorter screws have cost? 5 cents?
Wow...
