I connected a 2.5" hard drive to one of those IDE-to-USB adapters. If I do nothing more than apply 5 volts to the adapter, can I expect the hard drive to at least spin up?
Thanks.

✔ Best Answer
If everything is working properly, yes, it should spin up as soon as power is applied.

Make sure you have any jumpers set correctly. Most require the drive seat as Master

Thanks, Stuart. I thought jumpers were not relevant when a hard drive is connected as a USB device. Please advise.

I disagree, even with power applied many units will not spin up until the ide/sata connection is connected via the usb cable. Did you try plugging the usb with power supplied?

Yes. Even with the power supply connected and the cable connected to a USB port, the hard drive did not come to life. This is not the first time such a thing has happened. Makes me feel as though I'm doing something wrong.

If this USB adaptor has a separate power supply it should still spin up when the power is applied without connecting to the USB port. All the USB power supply does is supply power for the USB adaptor, a maximum of 500 mA which is nowhere near enough to power and IDE hard dsik.

Every IDE drive I have seen spins up as soon as power is applied, with or without anything connected to the data connector. That is because the drive controller is incorporated into the drive hardware. Applying power initialises the drive controller which spins up the disk,.

Try connecting the power without any connections to the USB at all. There may be a fault in the USB adaptor that is preventing the drive from spinning up.

Bear in mind that with modern hard drives it can be difficult to detect if the are spinning as they are so quiet. You may need to get it close to your ear.

I digress, Stuart. Indeed we are talking an ide laptop hard drive that has no separate power source, I am thinking of some sata's that do and do not begin spinning merely with power. Have had lots of sata's that would not begin spinning until the usb portion connected, but on the ide there is no such power. All I can say is with regards to that is to for fun try a back side usb port, and some ide drives just did not like the usb adapters and swapping cables sometimes worked sometimes not, but you have nothing to lose.
