I can't add 1 more hard drive to my OMV5

Hello

I would like to add a third 2tb disk to my Pi 3 b+ where OMV is installed. At this time I already have 2 hdd connected via usb2 : one of 100 gb and a second of 2tb.

When I connect the third disk via usb2 the system is going totally crazy and the two other disk disappeared.

Am I doing something wrong? Is there any explanation? Is this known ?

Thanks for your support,

Best regards

I'll try!

thank you Soma
