What v12 slim harddisk? The slim ps2 doesn't come with a hdd and you can't fit one internal to it. But you can take a HDD with a external closure and connect it via USB.
Most HDD's should have the power requirements written on them.
kl1k ,good morning welcome to planet Earth.Ever heard of Hd connect ?
Rohit,tell the technician to take a pc power supply and do a 12 v like it's there :p
for a harddisk! nooo its not all twelve volt. i dont know if your talking bout a pc hard drive its goes
<5v---Gnd---Gnd---12v>
i dont know about laptop hard drives
Actually I have! I didnt know exactly what the original poster was referring to for v12 slim harddisk - i know you can take a HDD and connect it via hdconnect, or via a external USB case.
the best and probebly the easyest way to do it would be just to take a transformer from a 3.5inch external hdd bray (for a PC) as it is desighned for it and stable.Quote:

if you go to the hdd maker's websites, you will find specification pages where they will tell you exactly how much they are asking you to provide to the hdd for the stable operation.
i think 3.5" uses 300 to 500mA from the 12v when idle & at the heavy operation it will go up to around or even more than 1.0A; i think 250 to 500mA for 5v is enough
the problem is when the hdd starts up; because motor produce highest torque when it is not moving, starting up current might be as high as 2.0A...maybe even more
for the 2.5" notebook type uses only 5v for both motor & the circuit...the current it nees is probably less than 1A even during the startup
if you use 2.5" notebook type 5200rpm drive, i think the pstwo power supply can provide enough power...just add 5v voltage regulator on between 2.5" hdd & ps2 ac adaptor
the best way to add hdd to pstwo imho is to use external usb/ieee1394a adaptor; regular pc ide cable & connect to both usb2 to ata adaptor & pstwo, then put a power switch between usb2 adaptor & power supply so that you can connect your ps2 to pc without taking apart
I had a look at my external hdd bay power adapter it delivers 5V at 1.5A and 12V at 1.8A .
