Parted problem on large disks

Hi guys,

I don't know if it's a bug but I send it anyway to this bugreport.
I hope you can help me.

I have EMC AX100SC storage box. I created a very large disk pool and virtual disks (4.5TB)
I'm using RHEL4 Linux 2.6.9-34.EL #1 Fri Feb 24 16:44:51 EST 2006 i686 i686 i386 GNU/Linux
And I'm also using parted shipped with RHEL4 .

I get this error when I'm using parted on the 4.5TB storage box. See below ..
address@hidden ~]# parted /dev/sde

Using /dev/sde
(parted) p
Error: Input/output error during read on /dev/sde

This is in the message log when I do use parted on the diskbox….
Current sde: sense key Medium Error
Additional sense: Unrecovered read error

I let fdisk -l output for sde follow as well
WARNING: GPT (GUID Partition Table) detected on '/dev/sde'! The util fdisk doesn't support GPT. Use GNU Parted.

I have been using parted on other storage boxes we have but they are a bit less or 3.3TB and it worked fine.

I hope I'm asking the right people for help and you have enough info to deal with.
