I am running Ubuntu 15.10 in VMware Workstation. HOST OS -WINDOWS 10

Now my hard disk is full and i attached a new vmdk hard disk and rebooted the system but while trying to mount it using sudo /dev/sdb1 /data it's giving following error 

mount: wrong fs type, bad option, bad superblock on /dev/sdb

How to properly mount hard vmdk disk?

  • What is you host OS, which supervisor do you run VMWare (question body) or VirtualBox (tag)? Did you partition and format the new drive after creation? – Takkat Jun 03 '18 at 05:51
  • @Panther , i went through them but they are not helping me – Karamzov Jun 03 '18 at 06:23
  • @Takkat , OS , windows 10 and i caanot partition as its not visible in my ubuntu , only i can see it in fdisk - l utility – Karamzov Jun 03 '18 at 06:25
  • What command did you run and what error message did you get? – Panther Jun 03 '18 at 06:25
  • @Karamzov you need to run gparted in the guest Ubuntu for patitioning. – Takkat Jun 03 '18 at 06:29
  • @Takkat , paritioned using gparted and tried to mount using sudo /dev/sdb /data , its giving the same error – Karamzov Jun 03 '18 at 06:34
  • @Panther This question is not a duplicate. Karamzov asks how to use a new vmdk in an Ubuntu guest whereas the other question asks how to mount a vmdk in an Ubuntu host. – muclux Jun 03 '18 at 07:17

A vmdk disk for a virtual system is like a bare hardware disk for a native system. You can't mount bare disks, only filesystems. So you have to partition your vmdk disk and make filesystems on it (with gparted and mkfs).

Partitioning gives you a partition named /dev/sdb1. Then you create a filesystem with for example mkfs -t ext4 /dev/sdb1. Now you can mount /dev/sdb1.

  • Partion done and now i tried to mount using mount /dev/sdb /data but its giving an error – Karamzov Jun 03 '18 at 06:43
  • If you have done partitioning the first partition is named /dev/sdb1. You have to make a filesystem in your partition, for example mkfs -t ext4 /dev/sdb1, then you can mount /dev/sdb1. – muclux Jun 03 '18 at 06:57
  • its done and mounted , i was thinking microsoft way and this made it difficult. now its mounted and is accessable – Karamzov Jun 03 '18 at 07:01
  • Done............ – Karamzov Jun 03 '18 at 07:05
  • i have one more question, is is posssible to attach the current partion to my existing partion that is merging sdb with sda – Karamzov Jun 03 '18 at 07:06
  • As the name 'partition' says, partitions are separate. If you want to use /dev/sdb1 for let's say your pictures, you could create a folder /home//my_pictures, then mount /dev/sdb1 /home/<my user>/my_pictures. If you include your new filesystem in /etc/fstab it can be automatically mounted at boot time and you can use it like your primary device. – muclux Jun 03 '18 at 07:11
  • how to add this in /etc/fstab ? – Karamzov Jun 03 '18 at 07:16
