Some backgroundThe disk itself was worked on by a friend and is said to be still intact, undamaged and still mountable/recoverableThe disk was part of a software raid 1 on Ubuntu 12.04The other disk in the original raid 1 was formatted and used for another purpose, leaving the current disk (the one in question) still technically part of a raid that no longer existsWhat I have tried alreadyBasic mountingI added an entry to fstab, marked the disk as ext3/ext4 and tried to mount.Upon mounting the following error appearswrong fs type, bad option, bad superblock onAnd in dmesgEXT4-fs (sdc1): VFS: Can't find ext4 filesystemI have tried to find the file system type of the disk and have come up with$sudo file -s /dev/sdc/dev/sdc: x86 boot sector; partition 1: ID=0x83, starthead 254, startsector 63, 1953520002 sectors, code offset 0xb8Where I need some help / My QuestionsIs there a way to convert the disk to ext4 without damaging the data?Is there a simple way to mount the Linux 83 file type disk and recover the data?I have another disk currently free in case it is a possibility to somehow rebuild the raidMy main goal is to recover the data from the disk. I am open to all options.UpdateSome commands' outputfdisk -l /dev/sdc$fdisk -l /dev/sdcDisk /dev/sdc: 1000.2 GB, 1000204886016 bytes255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectorsUnits = sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x0005ed9cDevice Boot      Start         End      Blocks   Id  System/dev/sdc1              63  1953520064   976760001   83  Linuxfile -s /dev/sdc1$file -s /dev/sdc1/dev/sdc1: datahexdump -C -n 32256 /dev/sdc (Not sure if this could help or not)$hexdump -C -n 32256 /dev/sdc`00000000  fa b8 00 10 8e d0 bc 00  b0 b8 00 00 8e d8 8e c0  |................|00000010  fb be 00 7c bf 00 06 b9  00 02 f3 a4 ea 21 06 00  |...|.........!..|00000020  00 be be 07 38 04 75 0b  83 c6 10 81 fe fe 07 75  |....8.u........u|00000030  f3 eb 16 b4 02 b0 01 bb  00 7c b2 80 8a 74 01 8b  |.........|...t..|00000040  4c 02 cd 13 ea 00 7c 00  00 eb fe 00 00 00 00 00  |L.....|.........|00000050  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|*000001b0  00 00 00 00 00 00 00 00  9c ed 05 00 00 00 00 fe  |................|000001c0  ff ff 83 fe ff ff 3f 00  00 00 82 59 70 74 00 00  |......?....Ypt..|000001d0  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|*000001f0  00 00 00 00 00 00 00 00  00 00 00 00 00 00 55 aa  |..............U.|00000200  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|*00007e00
