I am running Ubuntu 10.04.4 thru VMWare Workstation. I added a second virtual hard disk drive, which is found under /dev/sdb , as shown below

enter image description here

How do you mount this to anywhere? (e.g. /mnt/sdb).

When I tried sudo mount /dev/sdb /mnt/sdb -t ext4 I get the error message back

wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so

    First of all, try to create partition on this disk. After that, you can mount partition with mount command.

  • @ymm even with this new, mounted hard drive, I still face the same problem as before. Unzip failed: No space left on device

It isn't enough to create a new disk, you have to create a filesystem on it. The exact command used depends on the filesystem type, a command provided by Fedora is mkfs(8), a frontend to the various commands doing it for each filessytem type. Or it is called something like mke2fs (for ext2/3/4), mkxfs (for xfs), ... Check the release notes for your distribution to see what is recommended here.
