TCL is not seeing my Western Digital 1TB usb hard drive
« on: October 18, 2010, 04:17:25 PM »
Any suggestions?

It works fine on every other distro I have.

Are you using boot code 'waitusb=n'? With 'n' a delay in seconds to ensure device recogition at boot time, typical values are 5, 10, etc. I'd suggest to first try it with a higher value and reduce it later (until it fails again).

Furthermore, please provide here the output of fdisk -lu and dmesg | grep -i usb for me to be able to "see" what's going on.

Maro,

I'm not using the waitusb code.  I didn't think I needed to since I can plug in the USB after the system has booted (yes?)

Now that I did those two outputs (see below), I see the USB drive at /dev/sdb. However when I attempt to mount the device in rox-filer I get the following error:

Quote

mount: mounting /dev/sdb1 on /mnt/sdb1 failed: No such device
Mount failed

There was one error.

You need to partition thedrive, and create a filesystem on the partition before you can use it.

Why would I want to partition it?

It's a USB drive full of data.

I am loading tiny core from CD.  I have the TC folder on a linux ext 3 partition.

So everything is fine as far as running TCL goes.   I just can't seem to mount the USB drive and I need to because that is where all the data I use is located (if this operating system is to be of any use to me).

I'm not clear whether the device in question was connected at the time when you ran those two commands. So let's be a bit more precise:
(1) boot TC, but keep the device disconnected,
(2) take a snapshot of 'dmesg' (e.g. via dmesg > dmesg_initial),
(3) connect your device and wait 15 seconds,
(4) take another snapshot and find out what has changed (e.g. via dmesg > dmesg_current ; diff -U 0 dmesg_initital dmesg_current),
(5) get some more information: fdisk -lu /dev/sd* ; blkid /dev/sd*,

Please report the result of (4) & (5) here.

If you want to get a better grasp of the timing of the recognition you could do what I just did:

dmesg > dmesg_prev
while [ 1 ] ; do
    date '+%T'
    dmesg > dmesg_now
    ADD=$( diff -U 0 dmesg_prev dmesg_now | sed -e '/^+[^+]/!d' -e 's#^+##' )
    [ -n "$ADD" ] && printf '%s\n' "$ADD"
    mv -f dmesg_now dmesg_prev
    sleep 1
done

In my case with an external USB drive it resulted in:

sd 6:0:0:0: [sdb] Attached SCSI disk
As I connected the USB drive at '12:54:30' this indicates to me that I'd have to allow for a delay of ca. 13 seconds to be reasonably safe for the detection to have succeeded. I'd imagine that for booting TC from such a device a lower value might work as well, as some of the time consumed up to the first message is just the spinning up of the disk, and that would go in parallel to the kernel and initrd extraction, hence the respective 'waitusb' value should be below 13 seconds (probably more in the order of 6-7 seconds).

You want to partition the drive because TC does not recgnize unpartitioned drives.
You can manually mount sdb, but TC will not find the tce directory unless it is on a partition.

Why would anybod buy a 1T drive and then not partition it?

I'm sorry for having posted reply #5. Who knows I might start having "senior moments".

The important information was already at the very end of reply #2 (I just overlooked it in the "noise" from the loop devices):
Quote
Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes

Thanks to gerald_clark for keeping the "real" troubleshooting on track.

I'll leave reply #5 unchanged as it might be helpful in some other (possibly related) cases.

docsulo,

On a sidenote, but not unimportant, the partition table of /dev/sda appears to be rather unorthodox in possibly more than one aspect. The impact of such might depend on software used to access the disk/partitions. 'testdisk' might possibly help to fix that.

I bought the drive when I was running Windows XP and didn't feel the need to partition it.

In any case, I have nearly 1 T of data on the hard drive and would like to access it. 

Is there a way to mount the hard drive or not?

As you claim

have a look how exactly those other distros handle it...

You might be able to fix your partition table - or create one if there really isn't any or it is empty - with the help of any software which would be capable to do so, but as you say it is full of data, you could never totally exclude a risk of data loss in such cases.

If I were you I would do some serious in-depth research about software to fix such issues, IMHO this is not only an issue which goes beyond the border of competence of TC but even of Linux.

First thing I would look at would be 'testdisk' http://www.cgsecurity.org/wiki/TestDisk and all its rather detailed documentation.

Most upper is also applicable to the partition table of your /dev/sda which looks wrong in more than one aspect.

If this is an ntfs drive you will need to install the ntfs-3g extension.
Then:
mkdir /mnt/sdb
mount -t ntfs-3g /dev/sdb /mnt/sdb

mount -t ntfs-3g /dev/sdb /mnt/sdb

Well that definitely moved things in the right direction.

Thank you.

Now I get this:

Quote
NTFS signature is missing.
Failed to mount '/dev/sdb': Invalid argument
The device '/dev/sdb' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
mount: mounting /dev/sdb on /mnt/sdb failed: No such device

Note:  This is a 1TB removable USB hard drive.  It was formatted NTFS.  It works fine on Windows XP, Ubunutu and Puppy Linux 5.11.

You could try 'ntfsmount' (contained in ntfsprogs.tcz) instead of ntfs-3g.

Not complying with standards in general has the consequence that it would be hardly predictable how any particular software would handle such a case.

mount -t ntfs-3g /dev/sdb /mnt/sdb

Got it to work with this:
sudo ntfs-3g /dev/sdb1 /mnt/sdb

I just changed /dev/sdb to /dev/sdb1 and removed the -t before the ntfs

Why did you have a -t in the command you used?  I see it in the manual at http://www.tuxera.com/community/ntfs-3g-manual - but can't find what it does.
