When I am doing cp -R at my system
cp -R \[Bark\]\ Java/ /Volumes/Seagate\ Backup\ Plus\ Drive/
its throwing this message
cp: /Volumes/Seagate Backup Plus Drive/Advanced: Read-only file system
cp: [Bark] Java//Advanced:unable to copy extended attributes to /Volumes/Seagate Backup Plus Drive/Advanced: Read-only file system.
I guess I need to make the backup disk in write mode How to change the mode of the backup disk.
Mounting on many UNIX systems is controlled by the etc/fstab file (see here). This usually specifies mount options for each device.
You need to change the mount options for the device you're interested in.
If you examine the /etc/fstab file on your system, you should see something along the lines of ro in the options column.
If you change that to rw and then remount it, it should be writeable.
You may want to change it back when you're done so as to protect the information on it.
For Mac OSX, fstab is still used but the file systems may also be under the control of automount - look up the man pages for automount and autofs.conf for information on how to configure those.
