    I have earlier successfully used a SATA\IDE adapter with a 12v=2A/5 V=2A power source (don't know what the two values actually mean here) for saving some data from a harddrive in a broken PC. Can I use the same adapter for saving data from a laptop harddrive? The adapters seem to fit with the extensions I have, but the specs on the harddrive says 5V 700mA. Or will the output of the power source be "too strong" here?

    that should be OK -
    you have an adapter - 5V 2A - so the max current is 2amps
    and you only need to provide 700mA or 0.7amps

    Yes, you'll be OK with that PSU/adapter, just like etaf said.

    THe PSU is RATED to 2Amps (2000ma). That's what it can deliever, max. If your device only requires 700ma, that's all that will be "served" to your device, up to the 2000ma limit.

    In general for all power supplies the Voltage needs to equal the device spec. but the Current (measured in Amps or mA, where 1000ma = 1 Amp) can be equal or higher

    Looks like you have a choice of 5 or 12 Volts, if so make sure it's set to 5 to match the HDD's spec.
