Mount secondary ext3 drive from ext4 filesystem

calivw78 · 06-05-2015, 12:44 AM

I've just completed a fresh install of Debian Jessie and am trying to mount my old root drive, which is an older Debian install on ext3. I've tried "mount -t" with both ext3 and 4 and the options but continue to get the following error. My search foo is failing me. I've found several articles talking about conversion methods from ext3 to ext4 but nothing that talks about what I'm trying to do. My overall goal is to copy the data off the old drive and on to the new one.

Code:

EXT4-fs (sdc): VFS: Can't find ext4 filesystem

Thanks in advance!

Probably you're trying to mount the device (/dev/sdc) rather than the partition (/dev/sdc1 or such).

You were spot on! I'm shaking my head at this point. For any others that stumble on this and need the help, I ran fdisk and started making sense of the filesystem structure and then mounted them accordingly.

Code:

root@redux:/# fdisk -l /dev/sdc
