sata disk recognised - but can't mount

[Simon Schori]

Hello

I have a Western Digital hard disk on a Promise SATA150 tx2plus SATA controller.
HD is listed as: ATA WDC WD2500JD-00G (Direct-Access) (as SCSI devices)
Controller is listed as: 00:0f.0 Unknown mass storage controller: Promise Technology, Inc. PDC20375
I can see the hd in the hardware browser, the filesystem is ext3 (had to format it on another computer,
on this one it crashed at a half)

But when I try to mount, it gives this error:

# mount /dev/sda1 /mnt/sata150gb -t ext3
mount: wrong fs type, bad option, bad superblock on dev/sda, or too many mounted file systems

lsmod: I have the module sata_promise loaded, but it still doesn't work

I have FC3 with kernel 2.6.9-1.667smp, anyone can help?

thanks in advance
