I have an external hard drive which I plug in. When I go to disk utility it says it's there but I can't mount it in order to copy or move files from it. ?? Haven't tried anything in the terminal yet, as I'm not sure where to go with that. When I type in sudo blkid to list the file systems, here is what comes up

/dev/sda1: UUID="37816aba-85b5-476a-aedf-a1cd3f0db76b" TYPE="ext4" 
/dev/sda5: UUID="a35c094d-e6eb-4b6d-a63a-8303ae2f567f" TYPE="swap" 
/dev/sdb5: UUID="58dea4d5-89e7-4e28-838f-8d26598a226b" TYPE="swap" 

I only have this one computer so I am not sure whether it works on other PC's/os's. The partition type is Linux(0x83) When I look at it in the disk utility, it says the device is /dev/sdb1. I can't even check filesystem.

I tried mounting it manually, sudo mount /dev/sdb1 /media/external and it comes up with this. `mount: you must specify the filesystem type.

What is the error when you try to mount it? – Alex R. Jan 20 '14 at 11:13
Yes! What is the error appearing when you try to mount/click on the drive?? and what is the file format it contains? (Optional: Does it work with other PC's/OS's)?? – AzkerM Jan 20 '14 at 11:30
