The so-called Dos 'Extended Partition' begins numbering with ad(x)s5.  It's 
been so long since I dealt with this. Partitions 'c' is a special 
designation and 'b' usually is reserved for swap. But a wild guess would be 
that your logical partition 1 (windows XP) would be ad(x)s5a, [substitute 
drive number for (x)]  - the next would be ad(x)s5d, and ad(x)s5e (maybe 
your 'Data' one?). You can manually use the mount command to test mount to 
somewhere like /mnt before trying to hardcode into fstab, if indeed you even 
wish to do so.
