After a problem with one of my Seagate 3.5" HDD of 6to (with its own energy supply), their Aftersales service sent me back 2 SSD drive (One Touch 4to + Expansion 2to).
My problem is that now, when I plug one of them (ext4 partition) on my Rpi4 (4go) nothing seems to work: I ear a small “bip” when I turn on the Rpi.
I am already using an old SSD for my system.
I have 2 questions for specialists:
Do you think that it is a energy supply problem ? In this case, Do I have a solution to add an extra supply ?
If it is a problem of energy supply, do I have to use an SD card in place of the SSD I use for the system ?
if i’m understanding you correctly you are using something with power over usb on the RPI.
i seem to remember RPI’s not having much power over USB so it might not be able to provide what the disk needs.
you could try a usb hub with an external power supply, sounds like that would solve it…
but not 100% sure… just a gut shot guess.
Agreed, if you are powering it over USB there are limits to how much power it can draw. It would be ideal to power the Pi via the standard power jack and a fairly beefy PSU.
Difficult to be sure, but it could. One of the best options in this case is to power your 2.5" drives with a powered external USB HUB on which you’ll plug your 2.5" cases. Finding a HUB with mechanical switches is the best IMHO as it will stay on in case of power outage.
As outlined by @SGC & @Knowledge RPis are known to be very weak for powering USB devices. I had tons of issues before I switched to an external powered HUB based setup.
You don’t have to, you just have to find a way to power your USB devices independently. An SSD is always a better option than an SD for the OS. SD cards tend to be slower and to wear off way faster than SSDs.
