unable to access external HDD

Question

I am new to Ubuntu. I've just loaded Ubuntu 16.04 and I'm unable to access my external HDD.

$ sudo fdisk -lu

$ sudo mount -t ntfs-3g /dev/sdb1/media/bal007

mount: can't find /dev/sdb1/media/bal007 in /etc/fstab

this external HDD was working fine with Windows 7 earlier

You are missing a space between /dev/sdb1 and /media/bal007. The hint is in the message displayed by mount: can't find /dev/sdb1/media/bal007 in /etc/fstab.

after keeping space it gives NTFS signature is missing. Failed to mount '/dev/sdb1': Invalid argument The device '/dev/sdb1' 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? – balu singh Dec 04 '16 at 08:09
also tried replacing sdb1 with sdb but again same message – balu singh Dec 04 '16 at 08:18
@balu singh: What does sudo file -s /dev/sdb /dev/sdb1 say? – AlexP Dec 04 '16 at 08:26
/dev/sdb: DOS/MBR boot sector; partition 1 : ID=0x7, active, start-CHS (0x0,32,33), end-CHS (0x3ff,254,63), startsector 2048, 488376597 sectors /dev/sdb1: DOS/MBR boot sector, code offset 0x58+2, OEM-ID "-FVE-FS-", Bytes/sector 4096, reserved sectors 0, Media descriptor 0xf8, sectors/track 63, heads 255, hidden sectors 2048, FAT (32 bit), sectors/FAT 8160, serial number 0x0, unlabeled; NTFS, sectors/track 63, physical drive 0x1fe0, $MFT start cluster 393217, serial number 02020454d414e204f, checksum 0x41462020 – balu singh Dec 04 '16 at 08:29
Your disk is encrypted with BitLocker: OEM-ID "-FVE-FS-". See Use (Windows) BitLocker-encrypted drive on Ubuntu 14.04 LTS. – AlexP Dec 04 '16 at 09:07
tried the link but got Sun Dec 4 16:34:00 2016 [CRITICAL] None of the provided decryption mean is decrypting the keys. Abort. Sun Dec 4 16:34:00 2016 [CRITICAL] Unable to grab VMK or FVEK. Abort. – balu singh Dec 04 '16 at 11:17
Try the Dislocker issues, https://github.com/Aorimn/dislocker. – AlexP Dec 04 '16 at 11:22
i finally took the longer route. downloaded windows trial version. unlocked my drive and again installed ubuntu. now it is working fine. finally i found that the bitlocker in windows is needs to be decryprted first. thanks for all your options. – balu singh Dec 18 '16 at 22:17
