IIRC tar doesn't handle special files, you know, dev's, pipes, stuff
like that. What you want is dump/restore.
first partition the new drive, lets call it sda for example.
for each partition do:
mount /dev/sda1 /mnt
(The above is from man restore. It needs to be pristine, it says.)
dump -0 -f - /dev/hda1 |(cd /mnt; restore -rvf - )
which means "do a level 0 (complete) dump of the old drive sending
the data to standard out, change directory to the new drive ,
restore the filesystem using the data coming from standard in,
do that for each partition
then edit your /etc/fstab on the right drives
reboot off the new drive
and if that doesn't work, try something else.
