Can't mount device












1














I can't mount my e-reader. Here's what I tried:



I connected my e-reader to the computer via usb. dmesg tells me the OS (debian 9) recognized the device and assigned /dev/sdb and /dev/sdc to it:



usb 1-6: new high-speed USB device number 6 using ehci-pci

I tried to mount /dev/sdb with mount /dev/sdb /media/ereader getting this error:



 mount: no se ha encontrado ningún medio en /dev/sdb


Which roughly translates to:




mount: no medium found in /dev/sdb




I also tried with the -t vfat option, and repeated the process with /dev/sdc, with the same result.



In case you ask, here's the output of sg_map:



/dev/sg2  /dev/sdb
/dev/sg3 /dev/sdc


And fdisk -l /dev/sdb (my own translation):



fdisk: can't open /dev/sdb: Medium not found


Output from lsblk -f:

  • So you get two USB storage devices, but no partition table, and Linux can't identify any file system. Please edit question with output of file /dev/sdb and file /dev/sdc (sometimes file can recognize formats the kernel can't). Last resort is hexdump -C /dev/sdb | less (or sdc), and see if you can make sense of it.

  • Please add the -s option to your file calls, like file -s /dev/sdc. You may need to run this as root, depending on permissions. Doesn't your ereader device export its empty memory card slot as sdb? That would explain the "no medium" error messages.

  1. check common fdisk -l

  2. what about sdc ?

  3. don't forget to check device status simultaneously on you e-reader itself (e.g. Data transfer/Charging/Media Access or so).

  4. needless to say root privilege is required

I had the same problem. At the end I discovered I was connecting my old e-reader to the SS-USB port. I changed it to the only simple USB port my laptop has and it worked like a charm!



Hope this helps.

I had the same problem. At the end I discovered I was connecting my old e-reader to the SS-USB port. I changed it to the only simple USB port my laptop has and it worked like a charm!



Hope this helps.

    Welcome to U&L! This doesn't sound like it would fix the problem described, but without knowing the exact hardware it's difficult to be certain. Were you definitely getting the same symptoms that the OP had (devices created OK, then the "no medium found" error) before applying this fix?
