Well, I'm not lying, honest :)
Sysinstall gives me a dialog that has three checkboxes: ad4, ad6 and ar0.
This got me confused, because I had never heard of ar0, and because the
manual page for ar describes some other driver (Digi/Arnet).
ad4 says 7476 cyls/255 heads/63 sectors (58643 MB),
Offset Size End Name PType Desc Subtype Flags
0 63 62 - 6 unused 0
63 120103137 120103199 ad4s1 1 NTFS/HPFS/QNX 7 =
ad6 complains about bad geometry (119150/16/63) and then shows this:
ad6: 7476 cyls/255 heads/63 sectors (58643 MB),
Offset Size End Name PType Desc Subtype Flags
0 120103200 120103199 - 6 unused 0
ar0 shows
14952 cyls/255 heads/63 sectors = 240203880 sectors (117287 MB)
Offset Size End Name PType Desc Subtype Flags
0 63 62 - 6 unused 0
63 240187752 240187814 ar0s1 1 NTFS/HPFS/QNX 7
240187815 18503 240206317 - 6 unused 0
Maybe I should mention that the controller is actually called "Iwill
SIDE-RAID 100" but it does have an HPT370 chip in it. And yes, it has NT
on it (hence NTFS).
I don't know what to make out of it, but I hope you can.
Thanks

Uhm, if a RAID array is foundm you cannot access the individual disks,
the driver does not allow for that.

The RAID code is implemented in the ATA driver (ata-raid.c) and tbat
takes over from the BIOS as soon as we are airborne (the BIOS is only
needed and used for booting).
However, there is no way to rebuild the ATA RAID from FreeBSD (that may
soon change though) you have to use the BIOS for that...
