Could you paste the command(s) that resulted in the error message above.Thanks a lot for your reply
I found the solutionI had the same error message when trying to mount a secondary hard drive using: mount /dev/hdb5/ mnt/hdb5 The hard drive was physically placed in the IDE1 position and detected in the bios. Running: cfdsik /dev/hdb showed that the hdb5 partition was created and was of FS type 83 (Linux Extended), but I still couldn't mount. I finally figured out that I hadn't formatted the drive, so I used: mke2fs -cv /dev/hdb5 to do so, and after the filesystem was created I could mount till the cows came home!
