I just took FreeBSD for desktop use but all my important files are in Linux partition. When I try to mount my Linux ext3 partition that is on my Serial ATA disk I get this:

mount -t ext2fs /dev/ad4s1 /mnt
ext2fs: /dev/ad4s1: Invalid argument

But I can mount other ext3 partitions that are on same hard disk with freebsd:

mount -t ext2fs /dev/ad0s2 /mnt (this one works)


In Linux my Serial ATA disk is /dev/hde and other is /dev/hda
I thought that hde1 would be ad4s1 in FreeBSD

Is your /dev/hde on primary or extended partition? If I'm not mistaken, the primary slices are numbered 1-4 and logical (on extended partitions) 5 onwards.

It's in primary partition (/dev/hde1)
In fact, it's the only partition I have in my SATA disk and all my home directory files are there.

When I did fdisk ad4 I got this:

******* Working on device /dev/ad4 *******
parameters extracted from in-core disklabel are:
cylinders=238216 heads=16 sectors/track=63 (1008 blks/cyl)

Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=238216 heads=16 sectors/track=63 (1008 blks/cyl)

Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 131 (0x83),(Linux native)
start 63, size 240121665 (117246 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 1023/ head 15/ sector 63
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>

Hmmm... /dev/ad4s1 should be correct then. One thing to try: run fsck while in Linux, then boot to FreeBSD and try the mount again. Let us know if that helped.

I ran fsck /dev/hde1 and it didn't find any errors. Anyway I booted to FreeBSD and this time I ran mount /dev/ad4s1 from text mode. Now I got this error that didn't appear when running mount command from KDE console:

Warning R/W mount of ad4s1 due to unsupported optional features

I was able to mount linux partition as read only.. well that's ok for now but if someone knows how I get it writable please tell me

freebsd 5.2.1
the same dmesg here. i'm sure it's clean.
