problem with a device >2TB

[christian gattermair <christian.gattermair@mci.edu>]

hi!

i use debian sarge with 2.6.8-2-686-smp and like to use an raid device (sda) 
with 3 TB.

i have read in the internet and found that there is an kernel feature called 
LBD. it is activated

but with cfdisk:

cfdisk /dev/sda
FATAL ERROR: Cannot get disk size

with fdisk:

fdisk /dev/sda
You must set cylinders.
You can do this from the extra functions menu.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

fdisk in expert mode i can max. set cylinders to 1048576 and this are only 
2TB ....

in syslog i can see following output:

kernel: sda : very big device. try to use READ CAPACITY(16).
kernel: SCSI device sda: 6445080576 512-byte hdwr sectors (3299881 MB)
kernel: SCSI device sda: drive cache: write back, no read (daft)
kernel:  /dev/scsi/host0/bus0/target0/lun0: p

thx 4 any hint or tip

thanks,

christian
