iSCSI Drive larger than 2TB possible?

Hello,

I have an Raid 5 with 5,5TB on an transtec nas with Windows 2003 Storage Server.

Everytime when I create a virtual drive larger than 2TB I get this error message:

"The wizard cannot create the virtual disk using the file XXX. The specified virtual disk size exceeds the currently supported size of 2048GB. Specify a smaller disk size. "

But it should be possible to create larger drives?! Does somebody has an hint for me? :)

greetings from Bern, Switzerland

I am aware that windows 2003 server 64 bits version support SCSI devices larger that 2TB. See the following link:

Hope this put you in the right direction.

Are you sure you are using GPT/GUID partitions?

MBR Disks are limited to 2tb disks, whilst Win2k3 with SP1 and like Fnassif says Win2k3 x64 supports the use of GPT partition table which supports far greater partitions. See http://www.microsoft.com/whdc/device/storage/GPT-on-x64.mspx for a small howto convert to GPT

I thought there "MUST" be a solution. Maybe the Windows tools are crap?! Any alternatives? I have a 0815 Qnap Nas @home and I need 2minutes to built a 3TB Virtualdrive...

Anyway, thanks for your answer, I still hope somebody has an Idea.
