I inputted a partitioning standard, msdos, and got a message: you may need to update "/etc/fstab".

My usb card-reader will not mount now. "lsblk" shows sdb/sdb1, but sdb/sdb1 will not mount. Appears that I need to update /etc/fstab, but not sure if this is the only reason.

To update /etc/fstab, I tried "mount -a"; didn't work - haven't found any other commands for it yet.

The output is " / = ignored" "/tmp = already mounted". I didn't put anything into "/etc/fstab" as permission denied. Partitioned with "sudo fdisk /dev/sdX"

parted /dev/sdb1 print
Error: /dev/sdb1: unrecognised disk label
Model: Unknown (unknown)

Sector size (logical/physical): 512B/512B
Partition Table: unknown
Disk Flags: 
 parted /dev/sdb print
Model: Generic STORAGE DEVICE (scsi)
Disk /dev/sdb: 15.9GB

Disk Flags: 

Number  Start   End     Size    Type     File system  Flags
 1      1049kB  15.9GB  15.9GB  primary

update: after jumping through numerous hoops, deleting, creating, partition standard changed, formatting... It is now partitioned and recognized.

  • try editing /etc/fstab with sudo, you need elevated permissions to edit that file. please also put the update to the ticket body instead of a comment.

Formatting seemed to be the key. After that I had to redo some things involving the deleting and creating partitions and altering the partition standard. I don't remember the exact sequence of things.
