Nope
You don't need to mount the filesystems in order to do a "dd" on them.
However, your best bet is to do your "dd" command with the hard drive plugged into a computer that can recognize the partition table.
The "dd" and the "dd_rescue" command is a direct device dump to a file or second device, so mounting the filesystem that you are trying to dump is bad. Actually, you shouldn't have your device mounted if you are trying to do a device dump of it.
Keep in mind that if your critical filesystem-related sectors of your dd imagefile are corrupted then you may have some difficulty in mounting the imagefile. This is why you should do your dump on the computer that plays nicest with this hard drive.
Also, hard drive corruption can be a continuing process so your best option is to do a backup before things get any worse. And doing multiple reads on a failing hard drive can make things worse depending on what type of failure that you are experiencing.
Good Luck.
