Hello give this a try:
Become root or use sudo:
Plug your device into the system and identify the correct partition name.
Or you can use this to identify.
Prompt>dmesg |grep -i 'USB device'
You should see something similar to this:
Prompt>grep USB /var/log/messages
Now we are going to Mount the partition to an existing mount point (directory).
Aug 29 11:52:26 kernel: USB device sda1: 3903488 512-byte hdwr sectors (1999 MB)
Create the mount point. I think you already created /data1 as you mentioned.
Now let's mount the drive on the new mount point. Remember if yours is not /dev/sda1 change it to what you received from the grep of /var/log/messages.
Prompt>mkdir -p /mnt/data1
Verify that are mount was successful with:
Prompt>mount -t vfat -o rw,users /dev/sda1 /mnt/usbdevice
You should see something like this:
To remove the USB drive you must unmount.
/dev/sda1 on /mnt/usbdevice type vfat (rw,noexec,nosuid,nodev)
Permission should be Read And Writable as is. If not please Post the output of this command:
If you have issues in any of the above steps. Do not hesitate to post the error or your question or concern.
la -alh /mnt/usbdevice
