Unhappy mp3 powering but ''unknown device''


Dear All,

I am a very novice level computer literati. I recently installed Linux Mint Cinanmmon, I have had no problems with it so far on my notebook (Advent), nor have I had any problem with the most recent issue which brings me to yourselves (the masters: and I really must salute you all, you have helped myself in the past a lot, esp. those who treat every problem like they are talking to a ten-year old, not advanced experts--Thank You).

Anyway onward to THE CRITICAL PROBLEM:

I have a small swees MP3 player, which is part of my life (a) my morning runs, (b) afternoon execrises, (c) work (d) walk home (d) travel etc, which has been doing okay, I can see it in the past and add or remove some files, but on saturday when I turn it on it said ''no files'', connected back on to my laptop, not coming up as usual (the problem might have been caused by my usual mounting and unmounting without following the usual ''make safe'' and so forth). Anyway, I was able to retrieved all the files using PHOTOREC (thanks to your advises), but I need my mp3 (one of those ppl who have ''special attachments to lucky things'')-- I can buy a new one But I want my old one (as explained).

The QUESTION: How can I make my laptop get back to recgnizing my MP3?

Please Help (I am online, since Saturday I have tried everything but seems not to work, minus retrieval above mentioned via photorec).

Hi TobiSGD,

First thank you for getting in touch.

Secondly, I see nothing when I plug in. The ''unknow device'' is when i do that thing which makes you search for mounted devices, var something or fstad etc.

the mp3 is plugged in at the present and taking on power, but I see nothing (i.e. file).

I have tried to find linux-equivalent of ''device/drivers manager'' but nothing (it is however shown on ''startup disk creator'', which asks do I need to erase it?-- should I, and perhaps it might be found as new device?/?) Others have said it is apparently due to MTP or something?????

I truly appreciate your support, sir/madam.

Hi saulsadd,

Can you please run "dmesg" in your terminal after plugging in your mp3 player?
Paste the output here after running it(dmesg).

Hi RaviTezu,

I'm wondering if somehow the memory is going bad or the fs on the device just got messed up. The fact photorec could find the device but others can't makes me think the fs isn't showing as valid.

You recovered your music - good.

First check the USB mode if you can. Some devices in MSC mode don't play well with Linux, so try changing to MTP.

Another unfortunate possibility is that you may need to reformat the device to fix the filesystem.

From that output I would assume that this is in fact a hardware error, but there are at least some things one can try to recover that device.
At first, I would try to completely zero out the device, using dd:
Code:
dd if=/dev/zero of=/dev/sdb bs=512K
This will take a while, so get yourself one of your favorite drinks.
After that use fdisk, cfdisk or GParted to create a new partition table and a new partition (most likely FAT32 is the needed format).
After that I would test it again. If you still have problems get used to the thought that you most likely have to buy a new one.

this what the system returned when I typed in your advice

Your Advice: dd if=/dev/zero of=/dev/sdb bs=512K

The System Response: dd: opening `/dev/sdb': No medium found

Hi, Goumba,

how does one: [a] check usb mode [b] change MSC to MTP and [c] reformat the device

Try it with sdc instead of sdb in that case.

You can find these commands under the menu, usually under "System" or such.

As TobiSGD said try using sdc instead of sdb.


Please do the following steps:

1. Plug-in the mp3 Player(Make sure it is properly plugged in).
2. Execute the
Quote:
df -h
&
Quote:
fdisk -l
(fdisk -l should be executed as root/ using sudo i.e
Quote:
sudo fdisk -l
)
3. Paste the outputs here.

Hi TobiSGD

Thanks for the new advice I have been trying to follow it up,but it takes too long, I will try it again today, hopefully.
