I've seen many threads addressing this problem, but did not find a solution that applies to my situation. I have an out-of-the-box Windows formatted 3TB USB hard drive that I cannot mount. Error msg directly below:
[root@cnl10 ~]# mount -t ntfs /dev/sdc1 /mnt/backup3tb/
NTFS signature is missing.
Failed to mount '/dev/sdc1': Invalid argument
The device '/dev/sdc1' 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?
I get the same error with ntfs-3g.
And here is output of fdisk showing only that which applies to the external drive:
[root@cnl10 ~]# fdisk -l

Finally, I may have made thing more complicated by following instructions on this page:
specifically in the 'Problematic Drives' section, whereby I manually created fat32 partitions, though I'm not sure it actually 'worked' (the error and fdisk output above are unchanged from before attempting this partitioning). If I try to mount specifying fat32 filesystem, I get:
[root@cnl10 ~]# mount -t vfat /dev/sdc1 /mnt/backup3tb/
mount: /dev/sdc1: can't read superblock
If anyone can offer any insight into how I can mount this drive, I would greatly appreciate. There are no data on it since it's new, I had planned on formatting it anyway to use exclusively as a backup to my linux machine. Distribution is CentOS 5.5. Thanks!
