Formatting external harddisk

Post by wp.rauchholz » 2018/01/17 08:52:05

I am trying ot setup an external backup HD in NTFS format. the partition is created.[root@home ~]# fdisk -l /dev/sdc
Disk /dev/sdc: 2000.4 GB, 2000398933504 bytes, 3907029167 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 33553920 bytes
Disk label type: dos
Disk identifier: 0x13857d4d

Device Boot Start End Blocks Id System
/dev/sdc1 65535 3907029166 1953481816 7 HPFS/NTFS/exFAT
Partition 1 does not start on physical sector boundary.

But when trying to format I get an error message.
[root@home ~]# mkfs.ntfs -Q -L Backup1 /dev/sdc1
Failed to access '/dev/sdc1': No such file or directory
The device doesn't exist; did you specify it correctly?

What am I doing wrong?

Why are you using a non-native linux filesystem on it if it's for backups? The only reason would be if you need to use this same drive on a Windows system too. If you don't then use a linux filesystem like ext4 or xfs instead. Also check the output of dmesg for errors.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.
