HDD not enough power to run bigger sized HDD

I've not tested it on pure computer power.

It seems it doesn't provide enough power the SSD needs

Did not work for any 2.5 inch hard drive, I believe this is meant for only Data and includes not enough power for normal 2.5, the back of my HD says 5v .86a, tried 2.0 and 3.0 ports, never able to format

this cable wouldn't supply enough power over USB.

Carried enough power for a tradition hard drive and not just solid-state drives

The older ones (the fatter hard drivers) still require power and this will not work

Mechanical drives might not get enough power from the bus to spin up.

i had to purchase one with a ext power supply that worked beautifully

Didn't provide sufficient power to the hdd

I think it can't draw enough power from the USB port.

Keep in mind that if you're wanting to plug this into a 3.5" Hard Drive, you will need a different cable, as this one can't supply enough power to make 3.5" Hard Drives work.

I believe this has to do with there not being sufficient power sent to the drive since there's no extra power connector here

Don’t expect it to work /power a full size 3.5in desktop HD

Pros: works with both SATA and IDE drivesCons: powers the drive down after only a few seconds of inactivity, which I can't figure out to change.

They offer a version which supplies enough power to 3.5mm drives, but it's more expensive, and while convenient, if you have a 3.5mm drive, you probably have access to a desktop anyway

There is not enough power from the usb3 port to power some plattered drives.

It just doesn't have enough power because it simply can't get that much power from a USB port.

I understand that for the traditional "spinning platter" hard drives, some of these USB-powered adapters don't provide enough power and can have flaky behavior, so if you need to hook up one of those maybe you should get a SATA-to-USB dock with an external power supply

and i even tried using it on drives that wouldnt require a large power source (like laptop drives) and that did not work, complete waste of my money.

but it's not intended to, not enough power over USB

Should have power adapter to enable use on 3.5" drives, but works good on what its designed for.

Yes I can put the SSD into a caddy, but my 100% reliable SSD would only be as reliable as that cheap powered board in the external hard drive case

Fact is, HDDs need external power adapting to get enough power to spin up

It will plug into a 3.5 inch but there isn't enough power to drive the larger drive from USB.

It’s also great because the USB provided enough power to turn the SSD

It's just a bit misleading since this won't work with standard size drives because it doesn't supply enough power

There is not enough power.

1TB Drive the adapter doesn't have enough power.
