  • Since this is a privacy-oriented, it may be possible to disable Bluetooth permanently by modifying the speaker. These options are risky, and could easily result in a non-functional speaker.

    Option 1 is to disable the pairing button. If it’s a rubberized button with the contact pressing on the circuit board, you can put electrical tape over that portion of the board. For touch sensors, you could try removing the wiring, but you risk disabling all buttons.

    Option 2 is to disable the Bluetooth. You can attempt to remove the antenna or possibly just cutting the traces (metal lines) of the antenna. If you can identify a separate Bluetooth chip, see if you can remove the power to the chip. That could be as easy as desoldering the input pin and lifting it off the pad slightly, or cutting the trace entirely.












  • Woof, good theory. There is (or at least used to be) a section of board next to the CPU that controls the voltage, inherently controlling the internal clock speed and the FSB. As the temps increased, resistances and compositions possibly changed, causing that area to perform out of spec, theoretically damaging the board, CPU and memory.

    Just to be safe though, I would not trust that PSU either. Another idea is that the PSU was malfunctioning and sent inconsistent voltages, resulting in a multi-component failure.

    If you were a business that could afford to gamble on it I’d say risk it. $50 is a low cost for peace of mind. That PSU can go to local market at $10, with a disclaimer.




  • Ok my 20 and your 20 are not the same.

    I was saying the large numbers didn’t make sense if you don’t have a large fleet of drives. Say you have ten servers, each with ten drives, and the MTBF is 100 million hours (yay, easy math!). That means that half your drives will have failed after 100k hours, or 11 years of use.

    Some of the sites I have been looking at are saying that this number will increase significantly because 8 hours of daily use would give you about 33 years of use.

    I think I like the annualized failure rate better, but I don’t think either really tell a great picture.

    I would rather if the annualized rate were recalculated annually.

    Regarding the controllers, that has been nagging at me this whole conversation. Most SATA peripheral cards do not have heat sinks, but most SAS cards do. The SAS cards at least have a more rugged appearance.
