Hi all,
Today i just bought my brand new Seagate backup plus 1 TB external hard disk and i was shocked when it did not get detected in my Linux PC. At first i was thinking, there was some fault with the drive and i almost started checking the process for claiming warranty.
Suddenly something stuck me, thought to check it over windows and mac and to my surprise it worked great. So then googled over net and found that Seagate backup plus does not support for Linux.
Some investigation on dmesg

So here is the procedure to make it detect on a Linux PC.
There is a kernel module called UAC, which is the culprit. Disabling the kernel module, made my disk getting detected.
# rmmod uac
unplug and plug hard disk and it gets detected.
Its simple :)
Today i just bought my brand new Seagate backup plus 1 TB external hard disk and i was shocked when it did not get detected in my Linux PC. At first i was thinking, there was some fault with the drive and i almost started checking the process for claiming warranty.
Suddenly something stuck me, thought to check it over windows and mac and to my surprise it worked great. So then googled over net and found that Seagate backup plus does not support for Linux.
Some investigation on dmesg

So here is the procedure to make it detect on a Linux PC.
There is a kernel module called UAC, which is the culprit. Disabling the kernel module, made my disk getting detected.
# rmmod uac
unplug and plug hard disk and it gets detected.
Its simple :)
