I have recently bought 5 TB Seagate Expansion desktop hard drive http://www.seagate.com/www-content/product-content/expansion-fam/expansion -external/en-us/docs/expansion-desktop-hard-drive-ds1843-2-1502gb.pdf Basically, it is just ordinary 3.5“ HDD connected to the computer via USB 3. openSUSE 13.2 and Leap 42.1 (tested on several computers and DEs). fdisk, gdisk, parted, YaST partition module do not see it. dmesg reports some errors about uas module. I added uas to /etc/modprobe.d/50- blacklist.conf to blacklist it and I regenerated mkinitrd, but it doesn't prevent the module from load and it doesn't work. When I unplug the drive, system crashes. I tried LIVE CDs of Ubuntu, Fedora a openSUSE 13.1 promo DVD and they worked fine.

Did you compare which kernel modules are loaded in this case?

No, I was checking for uas as this was reported in openSUSE /Var/log/messages as the failing one. Which module should take care about this? If not uas, why should it be loaded (and fail) in this case? -- Vojtěch Zeisek Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux http://www.opensuse.org/ http://trapa.cz/

Why "fail"? You said other distributions worked; so check what module was used in this case. Then we can think about how to use the same module.

If anyone else would have same problem (in near future), solution (for me) was to add usb-storage.quirks=0x0bc2:331a:u in GRUB (press 'e' to edit the arguments and find line starting uefi).
