Fixing a corrupted USB drive
So , to begin, I have a 500 GB external HDD. I recently damaged it somehow while using it with Arch Linux (I don't know exactly what caused it). Now, KDE doesn't mount it automatically. Whenever I try 'mount' command I get message as :
mount: you must specify the filesystem type
The drive needs to be formatted before using it with Windows
I know of the
dd if=/dev/sdc1 of=image.
So what should I do? I apologize for the redundant nature of this post. But, I can't afford to lose almost 200 GB of data without trying anything.
Here's the output of "fdisk -l"
Disk /dev/sdc: 500.1 GB, 500079525888 bytes

According to your fdisk output, it seems as if there is one partition on your external disk, seen by the Linux OS as sdc1 (which means it is the first partition of the third disk presented to your system). Furthermore, it appears as though it is formatted with the newer version of NTFS (a Windows file system introduced years ago to improve FAT/FAT32) - at least that is how the partition is marked. Many Linux distros do not included support for NTFS in their kernel, but some do.
To find out, try the following command. It will make a directory mount point, and attemp to mount the partition read-only using the NTFS file system:
mkdir -p /mnt/usbdisk mount -v -o ro -t ntfs-3g /dev/sdc1 /mnt/usbdisk
