Error mounting /dev/sdb1

Ask Fedora
1

Fedora 43
It doesn’t mount an external hard drive connected via USB, with Fedora 42 it was perfect
Here’s what it tells me.
Error mounting /dev/sdb1 at /run/media/ andrea/EXTERNAL_USB: Unknown error when mounting /dev/sdbl

I gave the command

sudo fdisk -l

Here’s the house, giving me back

Disk /dev/sdd: 1,82 TiB, 2000398934016 bytes, 3907029168 sectors
Disk model: EXTERNAL_USB
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xcb205137

The HD contains data and I don’t want to format it.

This says sdb1
but this says sdd and does not show any partitions.

Something seems off there, including the fact there are no partitions on that 2TB device with a dos partition table

This may apply since up until windows 11 fat32 did not support any devices of that size. Only 32GB partitions were possible before windows 11.

What does lsblk -f show?

A vfat file system can look like a msdos partition table to the fdisk command. To access the data, mount the entire disk, that is, mount /dev/sdd.

Thanks Jeff and Villy, here’s what lsblk -f shows

ntfs file system. Connect to a Windows machine and check and repair the file system. Properly unmount, then try again in Linux.

Thanks Vanadium and ilikelinux for your availability
The package “ntfs-3g-2:2022.10.3-10.fc43.x86_64” is already installed.
I needed the HD and had to format it, now it works
