If you want to add another HD in VMware player, we need add something in vmx file and setup in ubnutu.

1. create vmkd file , attached is 4.7 G HD.
2. add in vmx file.

# Second SCSI disk p_w_picpath, size 4800Mb
scsi0:1.present = "TRUE"
scsi0:1.fileName = "Ubuntu-2.vmdk"
scsi0:1.mode = "persistent"
scsi0:1.startConnected = "TRUE"
scsi0:1.writeThrough = "TRUE"

3. setup it up in Ubuntu

after start Ubuntu, go to System-> Admin -> Partition editor, find the new hard driver deails like /dev/sdb

find uuid for this new HD
# sudo vol_id --uuid /dev/sdb1
return uuid like : eea4f9a2-fad6-45b4-91b4-91bf8f13ef91

create mount point in somewhere  or if you want to relocate your /home, just use /home

add HD in /etc/fstab file
# /dev/sdc1
UUID=eea4f9a2-fad6-45b4-91b4-91bf8f13ef91 /mount/point/Public           ext3    relatime,errors=remount-ro 0       1

4. restart Ubuntu

All done.
