Re: Vibrations unbearable
It is highly possible that your problems come from the vibrations. It seems to be not bad to replace it with a better quality with a fixing system HDD with shock absorbers which precisely limits the vibration from HDD (in your case, the HDD is certainly determined by single screw directly contact with the cage where they are installed and the rest of the box which spreads the vibration function when the HDD, the whole case).
According to this budget, personal, I do not know of any good quality housing with this type of fastening system for the HDD
Re: Vibrations unbearable
But do change the box will change anything?
Especially because I have to be sure of that.
Re: Vibrations unbearable
Following on the choice of new, there is a bit more difficult: the LANCOOL Metal Boned K1 seems the best (not only for the history of vibration HDD when it is equipped with only hand screws + washers rubber). But Me, I have a GIGABYTE Triton which I am fully satisfied (it is silent and I have no problem with my HDD vibration of SAMSUNG SpinPoint T166 of 250Gb/16Mb and 500Gb/16Mb). Also, the GIGABYTE Isolo 2x0 (the 220 in particular) seem slightly better on the side of vibration because they have rubber washers that do not have the Triton / Triton 180 (I have not know for Poseidon 310 ) ... but they are more expensive (which is not really justified).
