Sure you can. In fact I think it is easier to "inadvertently" delete your raw disks because (at least with Solaris 2.6) when you use the format command it tells you if a slice is mounted with a message such as:

Warning: Current Disk has mounted partitions.

With just raw partitions you get no such message. So if you have some eager Unix admin who forgets that you are using that partition they may say to themselves "Hey more space" and newfs it. I think that senario is less obvious that you are doing something wrong then this one:

rm system01.dbf

But you _only_ have dd available to you. With cooked you can use dd, tar, cpio, ufsdump (or vxfsdump), cp, rdist, etc...
