Hierarchical block is unconnected 3. Users browsing datazheet forum: My solution is datashert a bit overkill or simply a way to make simple thing amazingly difficult Anyway, i’d like to try the software option and have windows put my drive to standby, and see what it does.

While I wouldn’t do it regularly, I recently did it accidentally–no harm done. Mon May 07, 1: First I’d like to know what you have tried so far. Part and Inventory Search.

Those were just guesses, I have made no calculations on how the circuit should react on switch movements. I’m using windows xp and i have disabled the drive in device manager, however upon checking confirm that it is still spiining! What is the function of TR1 in this circuit 1. Tue May 08, Synthesized tuning, Part 2: Page 1 of 1.

If it is a Microwave power Transistor. This will cause infinite delay because while the drive apparently supports the feature, it’s not part of IDE standard and thus no controller supports it: Here’s a link to transistor’s datasheet: Ideally in the future I would like to move the spare drive to the loft in a nas enclosure as my router and cable modem are soon to be re-sited their.

HDDs spin up when they are powered up, even with data cable removed. PNP transistor not working 2. Losses in inductor of a boost converter 8. So, you may have to enable some operating system independent power saving feature. Dec 248: Mon May 07, 3: The ability to turn off a storage drive not in use is an easy way to reduce HG noise-obviously.

Your controller has to support delayed spin-up. If any of you happen to be a friend of single malt Scotch whiskys, see other pictures in the album as well.

SATA is supposed to hot swap-and I’d think most mobos and drives would be fine with that. Use a 5V relay that switches on the 12V supply for the drive. How this is done, I think the HDD remains in in waiting state until it receives a special command from controller to initialize.

Mon May 07, 6: I came up with this kind of possible solution for IDE “hotswapping”: Basically the reasons for such values were: 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. Maybe I should ask people at StorageReview. Similar Threads RF power transistor datasheet question 5.

With an external drive it wouldn’t even be very bothersome.

I would say this is a quite a stupid idea. Previous topic Datsaheet topic. Maybe Deskstars are really getting better. Latter might be quite a bit more disastrous.

Digital multimeter appears to have measured voltages lower than expected. Hi, All i know it’s P channel Mosfet. Equating complex number interms of the other 6. Just asking because f940n not too many opinions of them yet.

How can the power consumption for computing be reduced for energy harvesting? Last edited by whiic on Sat May 19, 6: Heat sinks, Part 2: Mon May 07, 9: Tue May 08, 7: Mon May 07, Mon Dec 31, 3: 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.

This feature is available in all manufacturers’ HDDs. It operates even when HDD is either logically or physically removed from the system.
