Mount NTFS on Ubuntu start up - rc.local vs fstab
Use the fstab; that is the standard place for automatically mounting volumes.
rc scripts are intended to be used for running generic startup commands and launching startup services.
As a side note, you don't have to use the UUID in the fstab if you really don't want to, it should work equally as well using /dev/sda8
Unable to login/ssh to server,if the hdd(sda8) gets died or corrupted somehow and its entry is present in fstab. but if its entry is in rc.local then i'm able get the login.
