There is no Linux 7 or 9. RedHat is one distribution of GNU/Linux, but there are many others.

ATA hard drives get their device names from how they're attached. The naming scheme doesn't change. Have you changed hardware configuration? hda is the primary master, b the slave, c the secondary master, etc.

/dev/hda = primary master IDE device
/dev/hdb = primary slave IDE device
/dev/hdc = secondary master IDE device
/dev/hdd = secondary slave IDE device

The numbers at the end refer to the partitions:
/dev/hda1 = first primary partition on primary master
/dev/hdc3 = third primary partition on secondary master
/dev/hdd5 = first logical partition on secondary slave
