And also it’s still not hotswappable as even with power removed, the data cable remains non-hotswappable. Something might break due to excessive voltage datasyeet. That would be -to the system-no different than any external.

How can the power consumption for computing be reduced for energy harvesting? Page 1 of 1. Mon May 07, 3: If you nuild a switch: Part and Inventory Search. 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 would say this is a quite a stupid idea.

SATA is supposed to hot swap-and I’d think most mobos and drives would be fine with that. Mon May 28, 3: I came up with this kind of daatasheet solution for IDE “hotswapping”: The ability to turn off a storage drive not in use is an easy way to reduce HG noise-obviously.

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. HDDs spin up when they datashert powered up, even with data cable removed. How do you guys sort this out? Latter might be quite a bit more disastrous.

Fans can be undervolted. I wouldn’t push my luck and try it. Tue May 08, 8: 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.

Here’s a link to transistor’s datasheet: It’s in TO package. ModelSim – How to force a struct type written in SystemVerilog? Mon May 07, The time now is I plugged the slave drive in after hearing the master spin down.

You can even prevent spin-up of Hitachi IDE drives by configuring them to delayed spin-up. Last edited by whiic on Sat May 19, 6: They can create low-level communication with the HDD and such communication is invisible to filesystem monitoring utilities.

I don’t know how to make this both simple and safe. I’ll be refining my calculations Maybe I should ask people at StorageReview.

Do you want to make it spin down after N minutes of idle or do you want to make it not spin up at all? Hierarchical block is unconnected 3. Choosing IC with EN signal 2.

If any of you happen to be a friend of single malt Scotch whiskys, see other pictures in the album as well. Remember that fans only use one voltage and ground. I don’t know about the above warnings Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. If it is a Microwave power Transistor. No registered users and 4 guests. To prevent this from happening, datazheet 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.

How do you get an MCU design to market quickly?

Users browsing this forum: Maybe Deskstars are really getting better. Your controller has to support delayed spin-up. This is because data connector also has GND pins It’s not complete spindown but it is usually enough to make the drive noise inaudible in a system.

I suspect a regular SATA at least if not doing any task,would be switchable by an inline switch on the 12 v feed. Hi, All i know it’s P channel Mosfet. 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 drives?
