Convert to Dynamic Disk greyed out

I just attached a 2 drive firewire JBOD that I want to span. I've created the partitions and formatted, but the "Convert to Dynamic Disk" command is greyed out on both of the drives. All other drives in the system don't have the command disabled. Am I doing something wrong? Running Win XP SP2.

I'm not sure it will allow you to create dynamic disks that are attached to "external" bus type interfaces, because of the potential for removal of one of the devices and hense crashing the set.

I've got other firewire hard drives that have the option available, but they are single drives, not a 2 drive case such as this one. I'm thinking that it's the bridge in the JBOD case that is causing the problem. I'm contacting the mfg. today.

Sounds like different formats on the different disks - FAT32 and NTFS.  I have come across new HDDs that had previously been formatted (Quality Assurance Testing).  Take a look at this link and see if it helps:  http://www.apcmag.com/apc/v3.nsf/0/BF0ACA31B055DBFECA256DE70081AAE9

Otherwise, try first setting up basic partitions and then converting to dynamic.  I know, all data on them will be wiped, but they're new anyway so what have you got to lose?  I also read somewhere that volumes that already contain system data cannot be spanned.  It may be that the dual casing installation caused the problem.
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I'm sorry, I'dforgotten to close this question after solving the problem. The mfg of the JBOD case stated that the bridge in their case didn't support dynamic disks in XP.

Please close this question.
