I'm quite new to Ubuntu and I've tried all the post related to my issue but couldn't solve it. I'll try to give as much information as possible.
I'm using 12.04 LTS on an external hard disk and boot my machine with Ubuntu. The external Hard disk on which Ubuntu is installed is partitioned into two: P5 and P6. P5 is the one where Ubuntu is installed and P6 is for storage purpose.
When I logon to Ubuntu, I'm not able to mount my internal hard disk. If I use
sudo fdisk -l, I can see the internal drive there but when I try to mount it, it gives me
NTFS Signature is missing. Here are the results of the two cmds:
$ sudo fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xeef597d0 Device Boot Start End Blocks Id System /dev/sda1 * 2048 625139711 312568832 7 HPFS/NTFS/exFAT Disk /dev/sdb: 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: 0x389ea96f Device Boot Start End Blocks Id System /dev/sdb1 63 106710400 53355169 7 HPFS/NTFS/exFAT /dev/sdb2 106711040 488392703 190840832 7 HPFS/NTFS/exFAT $ sudo mount -t ntfs-3g /dev/sda1 /media/external 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?
Here I'd like to inform that my internal hard disk is encrypted and is protected with a pwd. When I normally bootup my machine, it first asks me to enter the HDD pwd and then the encryption pwd and then it logs me into Win 7.
I think that it's because of the HDD pwd and encryption that I'm not able to mount my internal drive to Ubuntu but not sure.
Is there a way that I can mount my internal drive onto Ubuntu without removing the HDD pwd or encryption on my internal drive?
