multiboot problem

[Marcelo]

Hi friends, i have 3 hds in my machine and a external hd more, like this:

/dev/sda -(hd0)- ubuntu studio 10.04 and slackware 13.1 64
/dev/sdb -(hd1)- windows 7
/dev/sdc -(hd2)- backup
/dev/sdd (external hd) - (hd3) - windows 7


Well, the grub recognized both windows hds.

Take a look in my file /boot/grub.cfg:

### BEGIN /etc/grub.d/30_os-prober ###
menuentry "Slackware (on /dev/sda1)" {
insmod ext2
set root='(hd0,1)'
search --no-floppy --fs-uuid --set f95f0fa3-abc3-491d-86c9-f7cae35559ef
linux /boot/vmlinuz root=/dev/sda1 ro vt.default_utf8=0 vga = 773
}
menuentry "Windows 7 (loader) (on /dev/sdb1)" {
insmod ntfs
set root='(hd1,1)'
search --no-floppy --fs-uuid --set 4ee86670e86655ed
chainloader +1
}
menuentry "Windows 7 (loader) (on /dev/sdd1)" {
insmod ntfs
set root='(hd3,1)'
search --no-floppy --fs-uuid --set 8cf85b48f85b3026
chainloader +1
}
### END /etc/grub.d/30_os-prober ###
 
However when i try to initialize /dev/sdd (external hd), the grub initializes /dev/sdb, so...what's the problem?

Thanks a lot.

P.S: I checked  the uuid's, it's all correct.

Forgive me for my poor english.
