After installing Ubuntu 12.04, which I'm using right now and it works great, my extra hard drive was detected the first time I turned on my computer but then it does not show anymore on my Home Folder, when I run the Disk Utility says that has a few errors but when I try to fix it, says that hard drive is busy and cannot do anything else.
I've unmounted it and mounted again but nothing happens.
Do you know what can be going on? Cause the first time that I was able to see my hard drive it had all the files I have, but I don't know if deleting the partition will format the whole hard drive or just the ubuntu files.
THANKS in advance!
BY THE WAY, I'm new to Ubuntu... :S
