My pc doesn't see external hard drives plugged via usb

Hi, i got to recover some files and i plugged my old SSD to an USB adapter and nothing happened. I’ve tried with other HDD nothing happens. It’s like it doesn’t exist.

I have checked in bios it is present.

UPD if there is a software to recover it, do you have any suggestions?

p.s this ssd was on my old laptop with Manjaro KDE installed, if I’m not mistaken the filesystem is brtfs. i need to recover the /home directory.

lsblk shows my other ssd, but when i swap with the one to recover nothing happens.

Hello @p1xlize :wink:

  1. Unplug the USB Device
  2. Run sudo dmesg --follow on the terminal
  3. Plugin the USB Device again.

Any useful output there in the kernel messages?

Also:

lsusb -vt

I did it, no update like if i didn’t plug it in…no updates. It’s with every hdd that i have.

this is the output for lsusb -vt

Try any other type of cheap USB device: USB stick, USB bluetooth dongle, USB HID receiver, connect a phone via USB: does your PC is seeing any of that?
Are there any payload data transfers present in that USB port?

Try another USB port.

Did you do not disable USB port(s) earlier?

When does the issue starts to occur? Did you re-plug some cables inside?

External hard drives

HDD? not SSD?
many HDD at once or one by one?

About a 10 years ago to spin up a HDD it needs to consume a lot of power.
max power of USB2.0 is 5V * 0.5A = 2.5W (only)

I saw specs of 4TB HDD (3.5"):
4.5 W working state.
3.3 W idle.
And that’ is not even the spin up power consumption.

try to use USB3+ ports: it hat not less than 0.9A

May be you have bad USB cable (long or thin or made of cheapest copper with high chemical impurities) so that increases an electrical resistance and produces power loss to payload (in your case a HDD).

May be you have USB 2.0 cable but couple for simultaneous connection of a single HDD to 2 USB 2.0 ports to draw more current (so up to 0.5A * 2)?

Hi sorry for my absence. It’s a SSD that was in my mother laptop. the laptop was running manjaro kde plasma(brtfs file system). The SSD has about 3 years. i have connected him internally and externally. nothing works.

didn’t help either, i connected via usb 2.0 and 3.1 and even type-c. The bios sees him, but system don’t recognize him.
