ide drives and USB Enclosures


FC 12-x86_64/kde

I have a Acomdata external hard drive enclosure with a PATA hard drive
set to Master.
I want to just be able to read and write to it as a storage drive, lsusb
sees the enclosure Acomdata but not the drive, what do I have to do to
read/write to the hard drive ??



tail -f /var/log/messages ;

# mount -t ext3 /dev/sdc /mnt/harddrive
mount: wrong fs type, bad option, bad superblock on /dev/sdc,
missing codepage or helper program, or other error
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
In some cases useful info is found in syslog - try
dmesg | tail or so

# mount -t ext3 /dev/sgc /mnt/harddrive
mount: special device /dev/sgc does not exist


Also tried a fdisk /dev/sdc;

# fdisk /dev/sdc

Unable to read /dev/sdc

The drive is a ext3 with a / and /home partitions on it

At this i've come across this and found it to be that i need to run fsck (fsck.ext3 in your case) on the device before it will mount.

Also the output of fdisk -l could be usefull

/dev/fdisk -l /dev/sdc
bash: /dev/fdisk: No such file or directory


# fsck.ext3 /dev/sdc1
e2fsck 1.41.9 (22-Aug-2009)
fsck.ext3: Invalid argument while trying to open /dev/sdc

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>


# e2fsck -b 8193 /dev/sdc1
e2fsck 1.41.9 (22-Aug-2009)
e2fsck: No such file or directory while trying to open /dev/sdc1

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
