question: how to mount W95 Ext'd (LBA) partition

[elyasn]

i've googled everywhere, but to no avail. I would appreciate it if somebody can help, cos I would really to save my files on the W95 Ext'd (LBA) partition. So, my question is, how can I mount the above partition.

for ex:
fdisk -l gives
Device Boot Start End Blocks Id System
/dev/sdb1 1 19122 153597433+ 7 HPFS/NTFS
/dev/sdb2 19123 48640 237103335 f W95 Ext'd (LBA)
/dev/sdb3 19123 48640 237103303+ 7 HPFS/NTFS

as seen above, all I can say is sdb2 is my c:drive in windows and sdb3 is my d:drive. I hv no problem mounting sdb3. My main concern is that I cannot mount sdb2. I've tried

mount -t ntfs-3g /dev/sdb2 /mnt/ntfs1

but then it returns,
NTFS signature is missing.
Failed to mount '/dev/sdb2': Invalid argument
The device '/dev/sdb2' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?

then,
mount -t vfat /dev/sdb2 /mnt/ntfs1
mount:wrong fs type, bad option, bad superblock on /dev/sdb2,
missing codepage or helper program, or other error
(aren't you trying to mount an extended partition,
instead of some logical partition inside?)
In some cases useful info is found in syslog - try
dmesg | tail or so

can somebody tell me? ohh btw, I'm a linux n00b

Your partition table looks either wrong, or corrupt. For future posts
please don't make things bold. Entirely bold sentences are considered
yelling/shouting, which is rude, though I doubt that was your intent.
Aldo commands in computers are case-sensitive (as are
files/directories/etc.) so case sensitivity is important and makes all
your commands incorrect.

So the problem with your partition table.... sdb2 and sdb3 both have the
same starting and ending block, which is not normally valid. Also as
the message states 'sdb2' looks like an extended partition. If that's
the case then the next partition can have the same boundaries, but it
should NOT be 'sdb3' but should be something like 'sdb5'. Perhaps what
you typed is a typo and that would explain everything. If that is the
case try mounting the real number you were given and it should work. In
the meantime trying to mount an extended partition at all will fail as
it is not a place in which files are directly placed.

Good luck.

Hi
Your confused and trying to mount the extended partition, you need to
mount either sdb1 (C drive) or sdb3 (D drive)

An extended partition is just a container. You don't actually mount it, you mount the logical partitions inside it. If you look at the cylinder map, you will see that it contains the NTFS logical partition. So you've already succeeded, it's the "D" drive.

i'm sorry, my bad.. typo in pasting the returned command

fdisk -l gives
Device Boot Start End Blocks Id System
/dev/sdb1 1 19122 153597433+ 7 HPFS/NTFS
/dev/sdb2 19123 48640 237103335 f W95 Ext'd (LBA)
/dev/sdb5 19123 48640 237103303+ 7 HPFS/NTFS

if that's true: by mounting the D:drive I managed to mount the logical partition. Why am I not seeing my files in C:drive? folders like Crogram files, C:windows, desktop folder, etc.?

[elyasn]

btw,

i tried mounting sdb1.. but failed.

linux-bgjt:~ # mount -t ntfs-3g /dev/sdb1 /mnt/ntfs2
ntfs_attr_pread: ntfs_pread failed: Input/output error
Failed to read NTFS $Bitmap: Input/output error
NTFS is either inconsistent, or you have hardware faults, or you have a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows TWICE. The usage of the /f parameter is very
important! If you have SoftRAID/FakeRAID then first you must activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for the details.

ok.. feels like i'm in deep trouble..

Have you tried mounting /dev/sdb1? That's probably what windows maps to
your C drive.

Good luck.

honestly, at a glance, I don't understand a thing.. about fakeRAID/softRAID, but i'll do what I can tomorrow since it's getting late here...
