It's always recommended to use UUID instead of /dev/sdxN.

First line I think should be:

/dev/sda1 / ext4 errors=remount-ro 0 1

And the last two:

/dev/sdb1 /hdb1 ext4 defaults 0 2
/dev/sdc1 /hdc1 ext4 defaults 0 2

If you use UUID it should (in fact, the first line, the one for the
root partition, should stay the same).

Check the mount points for sdb1 and sdc1. Test if you can mount the
partitions there before modifying fstab and reboot.

The 'defaults' option implies that.

"defaults - default mount settings (equivalent to
rw,suid,dev,exec,auto,nouser,async)."

For a better understanding of this you should read [1] and maybe [2].

I think it's appropriate to insist in the use of UUID.

You're welcome. Hope everything works fine.
