I've been trying to mount a USB drive that's formatted as FAT32, and getting an error. The drive works fine on Windows machines.When I try to mount it with sudo mount -t vfat /dev/sdb1 /media/usbdev, I get mount:  /dev/sdb1 is not a block device.When I try to mount /dev/sdb to the same place (sudo mount -t vfat /dev/sdb /media/usbdev), I get mount: wrong fs type, bad option, bad superblock on /dev/sdb,        missing codepage or helper program, or other error        In some cases useful info is found in syslog - try        dmesg | tail or so.I've tried Googling around and searching this site. 1 and 2 seem like the most relevant questions, but the solutions proposed there haven't worked. I've tried adding a line to /etc/fstab (/dev/sdb1 /media/usbdev vfat defaults 0 0), also to no avail. I'm pretty confused - what's going on, and what can I do to mount this USB drive? I'd rather not reformat it since I have some important data on there. Here's what lsblk returns: NAME                  MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT sdb                     8:16   1  29.9G  0 disk   sdb1                  8:17   1  29.9G  0 part   sda                     8:0    0 119.2G  0 disk   sda2                  8:2    0   488M  0 part  /boot sda3                  8:3    0 118.3G  0 part    sda3_crypt        253:0    0 118.3G  0 crypt     mint--vg-root   253:1    0 110.4G  0 lvm   /    mint--vg-swap_1 253:2    0   7.9G  0 lvm         cryptswap1    253:3    0   7.9G  0 crypt [SWAP] sda1                  8:1    0   512M  0 part  /boot/efiAnd here's the relevant portion of sudo fdisk -l: Disk /dev/sdb: 29.9 GiB, 32078036992 bytes, 62652416 sectors 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: 0xc3072e18 Device     Boot Start End       Sectors  Size   Id Type /dev/sdb1       96    62652415  62652320 29.9G  c  W95 FAT32 (LBA)dmesg |tail shows the following: [152334.491944]  sdb: sdb1 [152334.493759] sd 3:0:0:0: [sdb] Attached SCSI removable disk [153063.602803]  sdb: sdb1So, it seems like the device is being recognized - it just won't mount. I'm new to Linux, so please let me know if I should provide more information. Thanks in advance.
Unable to mount FAT32 USB drive in Mint (is not a block device)
linux mint;mount;usb drive
Is not a block device is pretty specific.  It suggests you've accidentally overwritten the block device with a regular file at some point. In this case, ls -l /dev/sdb1 will show something other than b in the first column.  Here's an example from my system:$ ls -l /dev/sda1brw-rw----. 1 root disk 8, 1 Aug  3 08:32 /dev/sda1- in the first column means a regular file.  d is a directory.  b is a block device node.  c is a character device node.  p is a named pipe.  s should be a named unix socket, I think.This particular problem should go away if you just reboot.  /dev/ is a tmpfs, it is recreated from scratch on each boot.
