help: device in woody

[Debian User <sal_pox@yahoo.it>]

ho dovuto montare un nuovo hd su canale primario (master) del contoller
raid della mia asus a7v333-raid  (Promise 20276 RAID). ho ricompilato il
kernel attivando le voci : ata-ide > ide block device > promise pdc20276 modulo
										special fasttrak in kernel
										support promise software raid modulo
ecco parte del dmesg

PDC20276: IDE controller at PCI slot 00:06.0 PCI: Found IRQ 9 for device
00:06.0
PCI: Sharing IRQ 9 with 00:09.0
PDC20276: chipset revision 1
PDC20276: not 100% native mode: will probe irqs later
    ide2: BM-DMA at 0xb000-0xb007, BIOS settings: hde:pio, hdf:pio
    ide3: BM-DMA at 0xb008-0xb00f, BIOS settings: hdg:pio, hdh:pio
....
Promise Fasttrak(tm) Softwareraid driver 0.03beta: No raid array found

ma se faccio mount -t ext3 /dev/hde1 /mnt/dovevoglio... mi dice "is not
a valid block device". Qual'è il mio device allora? Grazie!
