Trouble accessing USB Hard Drive with ext2/ext3 patition

QNX USERS QNX6 - OS
1

I installed QNX Neutrino 6.3.2 on my IDE hard drive (Primary Master). Then I connected a USB Hard Drive which has an ext2 and ext3 partition on it. For some reasons I am not able to mount it and I get errors as follow:

bash-2.05a# ls /dev/hd10*
/dev/hd10          /dev/hd10t130      /dev/hd10t131
bash-2.05a# 
bash-2.05a# mount -t ext2 /dev/hd10t131 /fs/usb_drive
mount: Can't mount /fs/usb_drive (type ext2) 
mount: Possible reason: Corrupted file system detected 
bash-2.05a#

I am not sure why I get that error. I am sure there is no error on my drive because I can boot into Linux from that drive on other systems.

Here are some other relevant outputs:

Can anybody please guide me?

kushalkoolwal,

Read the ext2 stuff at this link and see if it applies to your harddrive.

Thanks Tim.

Actually I did read that piece of information before I posted the query but I was not sure if it really applies to my file system or not. Also does it applies to ext3 also?

kushalkoolwal,

Out of curiosity, what does a ‘df’ command show?

Also, it doesn’t appear to me that ext3 is supported. Is there any chance that /dev/hd10t131 is the ext3 partition?

What happens if you try to mount the /dev/hd10t130 partition with

mount -t ext2 /dev/hd10t130 /fs/usb_drive

Does that parition mount correctly?

Tim

ext3 is actually fully ext2 compatible

So you can mount it and read from it.

But i urge you to NOT write on ext3 in ext2 mode.
