unable to mount ext4 partition

[joe135]

Hi all, I am new to Ubuntu coming from Fedora, and am trying to mount a partition with the mount command, but I am having trouble doing so. fdisk -l tells me:

/dev/sda3       976900096  1953523054   488311479+  83  Linux

and blkid tells me:

/dev/sda3: LABEL="Data" UUID="e8fb3090-35d5-4b2b-884b-7b7065f60332" TYPE="ext4"

so, I presume I need to type something like this:

sudo mount -t ext4 -U e8fb3090-35d5-4b2b-884b-7b7065f60332 /mnt/Data Data

However, this doesn't work. Eventually I want to add this partition to /etc/fstab, and I figure once I get it to mount manually I'll be able to do so. Can anyone tell me what I'm doing wrong? Thanks.

Did you make a directory in /mnt called Data?

(And I don't know what the second Data is suppose to be.)

I did have a directory called /mnt/Data, but the field after /mnt/Data that you said you weren't sure about what it was for, was the culprit. I removed it and mounted the partition with no problem. Thanks!
