error: Mount: special device /dev/sdb1 does not exist

Belikewater · 09-04-2017, 11:36 AM

Hello everyone,

I am having trouble getting my ipod to mount, so that I can use clementine. I am on 14.2 Slackware KDE environment.

The error I am getting when trying to mount the ipod is:

Quote:

mount /dev/sdb1 /media/ipod
mount: special device /dev/sdb1 does not exist

fdisk -l returns the output of:

Quote:

Disk /dev/sdb: 7.4 GiB, 7952142336 bytes, 1941441 sectors
Units: sectors of 1 * 4096 = 4096 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0x60f75228

I have tried using just /dev/sdb but this will not work.

This is the output for dmesg

I do not plan to automount it, so I do not have any additional inputs in /etc/fstab.

Can someone please point me in the right direction?
Two of my books just have simple information on mounting devices, which is how I am attempting here, but for some reason this is not working on my Slackware machine.

To mount i{pod, pad, phone} devices, whether manually or automagically. You will need:
https://slackbuilds.org/repository/14.2/system/ifuse/
and, if your iPod runs iOS 10.x or newer Refer to this guide:
https://www.linuxquestions.org/quest...re-14-2-37346/

Thank you Kingbeowulf.

I have installed ifuse, but it seems like my system is still not reading my device. I am receiving the same output as above. I have rebooted, but the device is still not being read.

What version of iOS & model iPod? Exactly what kind of cable & usb ports?
Idk but it may not even be possible, since Apple's usb is ?limited?
Web-searching turns up mostly discouraging stuff;
maybe someone who knows, could post a definitive link or 2!!!
(Some interesting stuff from websearch: libimobiledevice ifuse, but Sorry, Idk)
p.s. Maybe GoAdvanced, Edit#1 Title, to add iPod/iOS &ver, for Thread visibility.

Belikewater,

yes, what is the model/version of your iPod? Not all mount the same way. For some older ipods and ipod nano, etc, there are a few more hoops to hop through. For example, older Gen1-3 iPod Nano needs to be set up as fat32 via iTunes in Windows. If its and iPod Touch, essentially an iphone, then the instructions I provided should work. Look at the output in /var/log/messages. When I plug in my ipod 5th gen nano:

Notice that, in this case, "sdf: sdf1" and (I mount automagically) udisk defaults to "/run/media/..." In your messages, a partition was not found thus "mount: special device /dev/sdb1 does not exist." It looks to me like the whole thing is formatted without partitions from the fdisk output. Did you try simply "mount /dev/sdb /media/ipod"?

With iOS 10.x, iphones and touch, there is no /dev/sdX since libimobiledevice/ifuse/udisk controls the mounting.

Note: no /dev/sdX! so "mount" won't work. You'll need to have udisk mount automatically in you DE or invoke ifuse. I will leave that as an exercise for the reader.

Also, make note that when troubleshooting mount issues for usb devices, useful utilities are:
lsusb
lsblk
And besides dmesg, more log information is in
/var/log/messages
/var/log/syslog
