If you use low-level tools like dd, you can trash things with equal ease--no matter what kind of partitions you have. Once you are inside of a primary or logical partition, there is no difference in how things work. (Most tools, utilities, etc. would not even know what kind of partition they were operating in.)
As I understand it, Windows has a problem being in a logical partition, but that's only associated with the partition tables (ie the routing TO the partition).
Note that partition tables which include extended/logical partitions act as "linked lists"--specifically, an "extended partition" does not define space on the drive--it is only link to a partition table where the first logical partition is defined. The fact that an extended has a size is--I assume--only to tell partition managers how much space is being set aside for logicals.
I've never tried writing data to an extended partition. ( I would not attempt this on any machine being used for any real work....
