Can you post the output of:

fdisk -l
(thats l as in list)

sfdisk -l
fdisk -l
(thats l as in list)


also

dmesg | grep sdb

dmesg | grep sda

the | is the "pipe" key

Looking at your output sdb has 3 partitions, this is most likely your hard drive, so its a SATA drive on the first IDE cable as slave, is that correct?
C.D,E are meaningless, as windows drive letters can be reassigned. From computer management, disk partitioner in windows or vista this will
give the information as to the hard drive and its real partition.

Post the outputs of these commands please, I'll see if I can help further
