I want to delete hdc4 and 5

Just give fdisk the "d" command and choose hdc4.

first of all delete Logical Partition (hdc5).
execute this

fdisk /dev/hdc

press 'd' and press 5 to delete hdc5. delete hdc4 after that.

root@darkstar:~# fdisk /dev/hdc

The number of cylinders for this disk is set to 4865.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): d
Partition number (1-5): 5

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.

The kernel still uses the old table.
The new table will be used at the next reboot.

[devils casper]

you have unmount partition first.
