mke2fs error

[Storms, Friedhelm]

Hello,

I'm trying to install RHEL 3AS on a rx4640 server.
Based on following partitions I tried to create new filesystems. 
This was no problem for sda1 to sda7 but for sda8 I got follwing error:

-/bin/sh-2.05b# mke2fs -jv /dev/sda8
mke2fs 1.32 (09-Nov-2002)
mke2fs: No such device or address while trying to determine filesystem
size

-/bin/sh-2.05b# fdisk /dev/sda

Command (m for help): p

Disk /dev/sda: 73.4 GB, 73407865856 bytes
255 heads, 63 sectors/track, 8924 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda8          4501      4999   4008186   fd  Linux raid autodetect

Any ideas what's going wrong with this sda8 partition?
