only shows the debian LVM
# vgscan
 Reading all physical volumes.  This may take a while...
 Found volume group "vol64" using metadata type lvm2

No. I don't know who created this LVM!

I use ntfs3g:
# mount -t ntfs /dev/sda1 /mnt/windows/
NTFS signature is missing.
Failed to mount '/dev/sda1': invalid argument
The device '/dev/sda1' 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?

The same problem:

# mount -t ntfs /dev/sda1 /mnt/windows/
NTFS signature is missing.
Failed to mount '/dev/sda1': Argumento inválido
The device '/dev/sda1' 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?


A lot of thanks!

post the output of the following commands

mount

df -h

cat /proc/partitions

lsmod | grep ntfs

uname -a

file /dev/sdxX (where 'x' is sda and sdb and 'X' is for each partition.
