Running Ubuntu 12.04 64-bit
I plugged in my External Hard Drive vs. USB last night. I had 1.5 TB
of data that I wanted to Rsync to my Desktop Hard Drive.
This morning I went to check the status of the transfer. I noticed that
it didn't finish, rsync showed me a lot of Input/Output Errors:
rsync: send_files failed to open
"/media/d8117361-193e-4571-afb0-50c4a461ba1e/zubin/Downloads/Paulo
Coelho-Eleven Minutes/CD 2/01.mp3": Input/output error (5)
I was wondering what happened here and realized that the USB External Hard
Drive was no longer mounted for some reason.
I unplugged and replugged the HD back in. The drive would be recognized
but would not mount.
I then tried to mount it via the command line, but got the following output:
zubin@zubin-main ~ $ sudo mount /dev/sdd1 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sdd1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
so I ran a tail on syslog and found that this system now has a duplicate UUID
and can not mount:
zubin@zubin-main ~ $ sudo mount /dev/sdd1 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sdd1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
I ended up mounting with the nouuid option, but this is not a solution for most
end users.
zubin@zubin-main ~ $ sudo mount -o nouuid /dev/sdd1 /mnt
I haven't rebooted my machine... not actually sure if that would help clearing
up this problem, but this should be fixed.
