There is nothing linked. Where am I supposed to look at?
Anyway, it should be clearly stated on the HDD, close to where it says the voltage, like this one
, in the line under the SAMSUNG name.
I've just seen that it does actually say the watts required, but still not the amps.
If you have also voltage required (and really, it should state it) you can calculate the amps following this equation.
amps = watts/volts
As a general rule of thumb, 0.5 amps (or less) at 5 volts is good. Actually if you can scavenge a HDD from an external enclosure that was operated by a single USB 2.0 cable it will do pretty well (as that's the max amps that a single USB 2 can give).
Of course, this does
impact the time you can run on battery.
whats your opinion on hybrid drives,
Uhm, no. Since it's connected through an IDE along the way, it makes no sense whatsoever to have anything better than a conventional HDD, as otherwise it's banging its head against the IDE bottleneck. Again, as long as you don't want to boot from it you won't really notice. Actually, you may not notice even if you boot from it, given that 5400 laptop HDDs are slower than that anyway. IDE is more than enough for music, movies and dumb data.
If you really want to place a better storage device (why anyway? SSD RAID for lulz?
), look if you have another sata connector placed in odd ways on that mobo, that you could pipe around with a simple sata cable.
Otherwise, if you feel brave and don't mind risking to blow up everything, you still have an e-sata port in that laptop I believe? With a bit of easy soldering you can re-route its sata II connection (yes, it's exactly the same as if the drive was internal) through a e-sata to sata cable that you will move around the laptop's internals, then connect to the additional HDD in the CD bay.
In either case of the two above hacks, the new HDD will need power and will be taking that power from the laptop's IDE connection, which is different from normal IDE as it does feature a few additional lines for power (so you have to take the soldering iron again and work on the CD bay adapter, to remove the double power/data SATA connector and place a power-only connector you can take from a ide to sata power connector
Just find each interface schematics and you're ready to go. At your own risk anyway.
