It operates even when HDD is either logically or physically removed from the system. The ability to turn off a storage drive not in use dataheet an easy way to reduce HG noise-obviously. Part and Inventory Search.

IRF9540N MOSFET. Datasheet pdf. Equivalent

Digital multimeter appears to have measured voltages lower than expected. They can create low-level communication with the HDD and such communication is invisible to filesystem monitoring utilities.

Synthesized tuning, Part 2: I wouldn’t push my luck and try it. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. r9540n

My eyes jumped open when the hard drive in my hand unexpectedly spun up as soon as I plugged in the molex. Originally Posted by Pharaoh of Egypt. SATA is supposed to hot swap-and I’d think most mobos and drives would be fine with that. I will look at HDDScan if i want to quieten down seek any further on the main drive.


Turn on power triac – proposed circuit analysis 0. Tue May 08, 2: Mon May 28, 3: While I wouldn’t do it regularly, I recently did it accidentally–no harm done. Of course T competes with smooth acoustic idle instead of darasheet seeks or low vibration, so they all have their weaknesses and strengths.

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

How reliable is it? Mon Dec 31, 3: Losses in inductor of a boost converter 8. I’m using windows xp and i have disabled the drive in device manager, however upon checking confirm that it is still spiining!

Something might break due to excessive voltage difference. I’ll be refining my calculations This feature is available in all manufacturers’ HDDs.

PDF F9540N Datasheet ( Hoja de datos )

Tue May 08, 3: Use a 5V relay that switches on the 12V supply for the drive. Mon May 07, 6: 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.

And also it’s still not hotswappable as even with power removed, the data cable remains non-hotswappable. Similar Threads RF power transistor datasheet question 5.


Reading a transistor datasheet? So, you may have to enable ff9540n operating system datashest power saving feature. Users browsing this forum: I don’t know about the above warnings AF modulator in Transmitter what is the A?

Mon May 07, 7: Mon May 07, 3: But apparently, under XPs power management menu, I can’t specify windows to idle my 2nd hard drive only, and not both of my hard r9540n Maybe Deskstars are really getting better. Maybe I should ask people at StorageReview.

What is the function of TR1 in this circuit 1. There’s three ways to shut down the HDD: The time now is 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: Fans can be undervolted.

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. Dec 242:
