Topic: Can't format hard drive error message, 64 bit or 32 bit not supported.

Hi there,

“64-bit filesystem support is not enabled. The larger fields afforded by this feature enable full-strength checksumming. Pass -O 64bit to rectify.”

When I try to reformat my hard drive I get the error message, I am not entirely sure why I get it as I am running GParted on a computer (via a USB loaded with Manjaro) that supports 64 bit.

See link below for the log file.

Thanks

EDIT:
I removed "when I am running a 64 bit system anyways" from the code quote block

Re: Can't format hard drive error message, 64 bit or 32 bit not supported.

That 64-bit message is just a warning and not stopping the file system from being created.

This is the error which is being reported:

mkfs.ext4: Input/output error while writing out and closing file system

This looks just like what happened in GParted GitLab issue #88 - mke2fs Warning, had trouble writing out superblocks where hardware errors from the drive caused the failure.

Use dmesg to check the system log for I/O errors.
Use smartctl to query drive for SMART detected faults.

dmesg | less
smartctl -x /dev/sda | less

The Wikipedia page on SMART explains what all the SMART Attributes means.
