Harddisk not mounting: not recognized under Devices - Ubuntu

I am using Ubuntu 14.04 desktop computer.

According to my code I mounted my harddrive and then copy a file in it. I also use 2 USB for this copy operation.

Today I got into trouble. Firstly one of my USB's partition table is corrupted. For solving this I formatted my USB Drive. Then it looks OK. But after rebooting, my computer didn't recognize my harddisk under Devices. Although it looks in the output of fdisk -l and lsscsi when I attemped to mount it I'm getting an error.

• fdisk -l output:

  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

• lsscsi output:

  [1:0:0:0] disk ATA KINGSTON SNV425S D100 /dev/sda [4:0:0:0] disk ATA WDC WD2500JD-00G 02.0 /dev/sdb

• sudo lsblk -f output:

  NAME FSTYPE LABEL MOUNTPOINT sda
  ├─sda1 ext4 / ├─sda2
  └─sda5 swap [SWAP] sdb silicon_medley_raid_member
  └─sdb1

• sudo mount /dev/sdb1 /media/Disk1 output:

  mount: you must specify the filesystem type

Then I run this command:

• sudo mount -t silicon_medley_raid_member /dev/sdb1 /media/Disk1 output:

  mount: unknown filesystem type 'silicon_medley_raid_member'

Then tried this way:

• sudo mount -t ntfs /dev/sdb1 /media/Disk1 output:

  ntfs_mst_post_read_fixup_warn: magic: 0x00000000 size: 1024 usa_ofs: 0 usa_count: 65535: Invalid argument Record 0 has no FILE magic (0x0) Failed to load $MFT: Input/output error Failed to mount '/dev/sdb1': Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's 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 the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details.

My harddisk didn't exist in blkid output also.

I can not figure out what the problem is, I would appreciate if someone gives any suggestion.
