/me drags himself out of coding a conversion from PanFS ACLs to NT ACLs, 
and recalls that we had a similar problem with two IDE drives of the same 
type ...

/me wonders ... looks 

ad0: 76345MB <MAXTOR 6L080J4> [155114/16/63] at ata0-master UDMA66
ad2: 76345MB <MAXTOR 6L080J4> [155114/16/63] at ata1-master UDMA66

The geometries are the same, but, from memory, the BIOS reports them as 
different ...

/me checks ... courtesy of a serial console

   Pri. Master Disk    LBA,ATA 66    80GB  Parallel Port(s)  
   Pri. Slave  Disk    None                SDRAM at Row(s)   : 2 3
   Sec. Master Disk    LBA,ATA 66    80GB
   Sec. Slave  Disk    None

Hmmm, they were different. They seem to have been forced to the same.

/me shrugs ... tomorrow I can ask what we did.
