Hi Please see the below picture. The USB-Storage used to work well. It had 2TG size. now why its capacity become 0 B ? Thank you
Seems, VMFS is corrupted.
First check if device is detected by ESXI host under storage device.
login to ESXI host using SSH,
run this command df -h , do you see device
Also check this KB article to see if filesystem exist on device
