How to rebuild MBR and partitions table

**johnluk** · November 30th, 2017

sudo mount -t ext4 /dev/sdb1 /media/disk/
mount: /media/disk: special device /dev/sdb1 does not exist.

sudo mount -t ntfs-3g /dev/sdb1 /media/disk/
ntfs-3g: Failed to access volume '/dev/sdb1': No such file or directory

I wanted you to try to mount sdb, not sdb1 as I do not think you have a partition, just a formatted drive.

I did it at post #10

In post 10 you used NTFS and post 11 ext4, which is it?

on post #7 'oldfred' asked about - smart-Status', what is the results ? If it shows failure then it is a hardware problem and that must be fix first if possible.

on post #3 you wrote "The drive is 3.5" internal and using the usb put in." ?? are you saying the hdd is in a case of some type and connected via the USB port ?
if so, have you replace the USB cable and tried a different USB port, tried different computer ?
