Duplicate ID_SERIAL_SHORT when using USB enclosure #66

Closed geneccx closed 3 years ago

geneccx commented 3 years ago

Running into a somewhat strange situation... when I put my two drives in my DAS, udev cannot distinguish between any of my drives even though they have unique serials.

However, hdparm -I correctly identifies the disks uniquely:

# hdparm -I /dev/sda | grep -i serial
        Serial Number:      S3PTNF0JXXXXXX0
# hdparm -I /dev/sdb | grep -i serial
        Serial Number:      S3PTNF0JXXXXXX1

This makes it really difficult to use unassigned devices, as it seems to try and automount drives on top of one another. Any help would be greatly appreciated!
