I have an USB-SATA/IDE adapter, such as this one: Since it was a cheap product from China, the power supply that was included in the packaging no longer provides enough power to spin up a disk. I remember that back in the day, the 2.5" drives only needed the mini-IDE to work, so one did not have to connect the power supply. Since I do not really need to connect any 3.5" disks to my computer and the power supply is most likely a fire hazard even if I manage to fix it (I suspect the caps, though they are looking OK), I'm wondering if it's possible to power the disks from the USB port, old-school style.
It seems to provide the power as well, so this would be perfect. However, there does not appear to be much going on on the board, so I am skeptical about the product. So here are my questions:
- Should this even work?
- Will it provide all three voltages (3.3V, 5V, 12V) required by the SATA spec or is it just some kind of a 5V-only hack that works on a small subset of disks?
I know the questions are not very specific, but neither is the product description. I can try to expand on the question somehow if you let me know in the comments.
