I don’t say the switch cannot be done, I just say it will not be a simple switch you could use to turn off some regular equipment like fans.

With an external drive it wouldn’t even be very bothersome. Basically the reasons for such values were: Those were just guesses, I have made no calculations on how the circuit should react on switch movements.

First I’d like to know what you have tried so far.

PNP transistor not working 2. Tue May 08, 3: PV charger battery circuit 4. That would be -to the system-no different than any external.

I’ve seen this question several times Say fellas, this is something i’d thought of putting a switch on the 12v and the 5v of my 2nd sata hard disk and i’d never imagine there would be any risks to it. How can the power consumption for computing be reduced datashest energy harvesting? I don’t know about the above warnings HDDs spin up when they are powered up, even with data cable removed. I will look datassheet HDDScan if i want to quieten down seek any further on datashfet main drive. Just asking because there’s not too many opinions of them yet.

I suspect a regular SATA at least if not doing any task,would be switchable by an inline switch on the 12 v feed. No registered users and 4 guests.

SPCR • View topic – how to turn off my spare hard drive

Dec 242: SATA is supposed to hot swap-and I’d think most mobos and drives would be fine with that. Or remove power from that line last? I’m using windows xp and i have disabled the drive in device manager, however upon checking confirm that it is still spiining!

Hi, All i know it’s P channel Mosfet. That said, I think if you built a reasonably simultaneous 12V and 5V switch, you could probably get away with a direct switch, I imagine there is enough safety built into HDD to tolerate it, you’ll just be running completely out of spec.

I’ll be refining my calculations I plugged the slave drive in after hearing the master spin down. Previous topic Next topic.

Mon May 28, 3: You can even prevent spin-up of Hitachi IDE drives by configuring them to delayed spin-up. What is the function of TR1 in this circuit 1.

This feature is available in all manufacturers’ HDDs. The time daatasheet is I would say this is a quite a stupid idea. It’s in TO package. Mon May 07, 9: It operates even when HDD is either logically or physically removed from the system. They can create dtaasheet communication with the HDD and such communication is invisible to filesystem monitoring utilities. Your controller has to support delayed spin-up.

Part and Inventory Search. Something might break due to excessive voltage difference. Mon May 07, 6: How do you guys sort this out? Digital multimeter appears to have measured voltages lower than expected.

CMOS Technology file 1. To prevent this from happening, there’s delayed spin-up feature but this is typically used to delay spin-up only for a few seconds to prevent current spike at start-up.

F9540N Datasheet

Remember that fans only use one voltage and ground. Of course this is no solution to your problem since: Tue May 08, 7: I came up with this kind of possible solution for IDE “hotswapping”: My eyes jumped open when the hard drive in my hand unexpectedly spun up as soon as I plugged in the molex.
