SSD error on DietPi but working with Raspbian

Troubleshooting
1

hi DietPi devs,

I have a serious problem that prevents me from using DietPi, and that I really don’t understand.

I have a 1TB SSD that I want to use for storage. When I plug it in with DietPi 6.30, I get an error and it doesn’t work:

sda is never recognized and I cannot use the drive.

I was curious if the same thing happened on Raspbian Lite. Well, to my surprise, it worked there. So I was wondering, what is the difference between Raspbian Lite and DietPi? Did you remove some USB drivers?

Hi,

usually these type of errors are pointing to some hard drive issues like bad sectors. But strange that it is working on plain Raspbian Lite. Do you know if your SSD is supporting S.M.A.R.T.? If yes you could install smartmontools package and perform same self test on the SSD using smartctl.

The drive doesn’t have SMART capability. It’s an SSD, here’s what I got with Raspbian:

I don’t think there’s bad sectors, but really a problem with the driver in DietPi. Upon booting with Raspbian, I do get a warning, but this is not critical:

Do you know what was removed from the USB driver when you downsized Raspbian? I would really prefer to use DietPi than Raspbian (Lite)!

for this we would need to ask MichaIng as developer.

Any update on this issue? MichaIng or someone else? Thanks!

I see exactly this behaviour.
