I have two My Passport drives. Both work when attached on their own, but when one is plugged in the second never appears.
I have tried the solution here Can't use Two My Passport Essential at the same time - #8 by DiscJocky, and successfully changed the Unique Disk ID, but it does not make any difference.
I tried reformatting one of the drives, as suggested here - Can you connect 2 passports at the same time? - #7 by Nathan_H - but that didn’t work either.
And when I run diskmgmt.msc, then I only see one of the drives.
What should I do next?
