Usb power from mb to case top connector hdd enough

Hello,

do you think in typical atx case usb 3.x
wiring from the mb to the casing front side connector 30 cm would be too much
to spin up a 2,5 hdd, adding 30 cm cable.

just using a 1m cable from back panel only usb sticks work.
with hdd no change.

@sonyveijo you need to provide external power to the HDD, I suspect the USB power is not sufficient…

For several years I operated this drive attached to the USB 3.2 Gen 1 Connector on the front panel:

You don’t say what kind of drive and enclosure it is.

I bought several used laptop drives for $6-$10 each, WD, Seagate, Toshiba etc. I used them in a $6 Orico clear plastic 2.5 HDD enclosure. I copied 100-300 GB’s of data from them to the desktop daily, something like 14TB’s total and never had a problem.

I have some nice Aluminum 2.5" HDD enclosures and apparently they supplied cheap cables with them. I had problems when I used the supplied cables but they worked great with a better quality cable.

So make sure you have good quality cables and you should be ok. Some drives require a little more power than others too, so I try to get drives that require a little less power.

I also a have an external 2.5" Toshiba brand 1TB drive that came in a factory enclosure and it works just fine too. It’s 10 years old with very low hours and works just fine on multiple laptops and desktops. It’s a Toshiba Canvio Basics 1TB USB 3.0 External Hard Drive (HDTB310XK3AA).

I do have problems with some USB-C 10 Gbps NVMe enclosures. It’s actually the NVMe drives that require more power that are the problem, some work fine. I’m going to get a powered USB-C/A 10 Gbps hub to solve that problem. That’s an option for you too if your motherboard isn’t supplying enough USB power.

I invoked smartctl and it tells all.
