Please tell me where I can find a Simpletech power adapter for BOM 96200-41001-077?

welcome to USA, we use our own adapters here, 120vac and special plug AC side.
where do you live country.?
simpletech 320GB BOM No: 96200-41001-05
they sell them on ebay, why not look there and buy it.
output 12vdc 0.4 amps or MORE.
center pin must be + output end.

any pack 12vdc like above works, over 0.4amps.
and AC end correct and if you have 240vac make sure the pack does that too.

any adaptor that has a usb port as connection will do

Hi,
Have a look HERE

Try Geek Squad or a computer store that can do hard drive recovery.

What you are after is an AC adapter this model I found on ebay has 120 volts to 240 volts to 12 volts make sure the DC voltage output matches the Voltage of your hard drive. The current output has to be the same amount or larger in value. So if your drive needs 2A a 2A or larger value means it can handle the current load put on it by the Hard drive.

I have the same devise. The AC Adapter has this description on it: MODEL S120S150A3; INPUT: 100V-240V ac 50/60Hz 450mA Max; OUTPUT: 12V 1. 5A

Try to find a replacement on ebay, amazon, or contact Simpletech Support.

Hi there,

You need to install the hard drive driver for the PC to recognize it. If you don't have one, just look in the internet for a free driver.

The original power supply is "SB2D-020-1HA SIMPLETECH AC ADAPTER 12V 1.5A FOR EXTERNAL HARD DRIVE" . Just find a replacement with the correct size plug (center positive) that supplies 12v DC at 1.5amps (1500ma)

Actually the simpletech dosent need power adapters so u dont need to check for adapters and if you are connecting to usb2 port the power should be embaded so just connect the single usb cable not the both if using usb 1 then connect the both usb cable to usb port if u have already done this please try to change the usb cables wich is connecting the hdd and the pc something wrog in the cable for sure
thanks
