Same stuff with me, three years ago. Same device, same MO. I was unable to 
read my disks using on Solaris, because these MO were formatted in a 
proprietary way. Finally, I succeed but this is very difficult, and 
involves some tricky manipulations with data-loss risks.

Impossible using Windows NT...

I have no longer such problems, as our devices are able to export as DICOM 
on CDROM or MO. *Reformat* your MO disk using Windows NT Disk 
Administrator, then go to the main console and export as ACR/NEMA, SPI, or 
DICOM to your disk. Or export to a free space, and ask your sysadmin to 
move the data to your disk. Or use a DICOM client (good luck :).
