Looks to me that its working fine and is accessible as /dev/sdg. Since it can't possibly mount a blank drive, it wouldn't show on the desktop. You just need to partition and format it.

btw: better to just post the BOTTOM of the output. I know that it wasn't explained to you before, but most of that output is completely unrelated. This is the output of a log file, new entries are continually added to the end of the file, so the only thing of particular interest is what *just happened*.

Thanks for your help.

I used gparted to format my hard drive. The strange thing is if I format it to ntfs I don't lose any memory but when I formatted it to exp3 gparted says 14GB have been used but when I look at the free space on the HD 60GB have been lost.

5% space is reserved for root, you also have to account for the size of the journal. As for the display of 60GB used... you sure you're not getting confused between GB and GiB?

1GB=1,000,000,000 bytes,
1GiB=1,073,741,824 bytes (=1024x1024x1024 bytes).

The difference is that GB is straight metric base 10 and GiB "gibibyte" is an approximation of metric in base 2. When you have a hard disk that is labeled as 1TB, thats 1,000,000,000,000 bytes. When you look at the capacity using df or gparted, the size you see will be somewhat smaller because of this conversion. And to get really confusing, sometimes (most of the time), software will display units in GiB, but label them as GB. The reason for this is that GB (and other associated binary prefixes) were used to state values in base 2. The prefix GiB, MiB, KiB, etc., were only introduced in 1999 and to this date have not entirely caught on.

Sorry I haven't explained the situation very well.

When I plug the HD in an icon pops up that says 931.5 GB Volume. When I double click on the icon it says free space 870.1 GB.

However gparted says size 931.51 GB. used 14.81 GB. unused 916.70 GB.
