mount: wrong fs type, bad option, bad superblock on /dev/sdc1, New hard drive install

ronniekl · 05-03-2012, 01:07 AM

hello
I am trying to add a new hard disk drive to my PC using this tut:

http://www.yolinux.com/TUTORIALS/Lin...HardDrive.html

I've managed to get as far as the final command on that page:

Quote:

mount -t ext3 /dev/hdb1 /opt2

except for my situation it looks like:

Quote:

mount -t ext3 /dev/sdc1 /opt2

that command is giving me this error:

Quote:

mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

says to check syslog, here is the result of that:

last three entries there looking fishy. first of last 3 might suggest new drive is not partitioned correct.

I'm guessing something is messed up with partition table, or new drive is simply not partitioned correctly?

here is the result of fdisk -l:

you'll notice sdc1 is not in fstab, when I do try to add an entry for it (as directed in tut) and restart the system, Linux fails to boot after spewing some error that resembles "bad superblock" into root terminal (tty0). so I'm guessing I'll need to figure out that mount error before I add an entry into fstab for new drive.

should be enough info in this thread to see where the problem is, please check it out and let me know if you can help, if you need more info let me know, would just like to get new hdd working asap.

Adding a new hard drive is usually a pretty simple task. I would recommend you to leave out the "-t ext3" option and let the mount command figure out the file system itself. If this fails, you should repeat the partitioning-mkfs step again. In particular, /dev/sdc1 does not look like a linux partition.

/dev/sdc1 2048 3907028991 1953513472 f W95 Ext'd (LBA)

What I expect is something like:

Code:

siim@shiva:/etc/lightdm$ sudo fdisk -l /dev/sda

Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xe2d9e2d9

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *          63      208844      104391   83  Linux
/dev/sda2          208845   321299999   160545577+  8e  Linux LVM
/dev/sda3       321300000   488392064    83546032+  83  Linux

BTW, do you have a special reason to use ext3 instead of ext4?

Ugh - not your fault; (very) bad instructions.

Go back into fdisk, delete the partition (d) - if it asks for a number (unlikely), just enter 1.
Then create a new partition, but make it primary - (p). Give it all the space by taking the defaults. Then print the list (p) to ensure it has the correct type = x83. If not change it with (t) - should be straightforward for you by now ...

Write the updates (w) then quit (q). Best to re-boot, then mkfs - BTW, I agree ext4 would be better.

Yes, you have on a /dev/sdc1 only extended partition, without a primary and/or logical partitions, like is:

Code:

# fdisk -l
Disk /dev/hdc: 160.0 GB, 160041885696 bytes

Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xa1ada1ad

   Device Boot      Start         End      Blocks   Id  System

You may also want to tell us what do you want to do with this drive -- a single partition may or may not be OK. You may also tell a few words about your distro and computer.
