Mp3 usb player does not mount

[rodogh]

---

Hi,

from 2 weeks to now, I can mount my mp3 usb player. The conection is ok, cause I can mount another mp3 player in the same usb and the mp3 player is also ok because I can mount it in my work's computer.

I've tried to mount it but the system has not the /dev/sda device.

Any ideas ?

Thanks a lot !!!

Can you give us more details than that? What brand of player is it? Does it require some sort of software to access it or can you just load it like a USB harddrive? What are the exact messages you're getting when you run dmesg after plugging it in? What version of Mandriva are you using?

Hello again,

the mplayer is very old nowadays. I've been using it as a usb storage without any problems until now and without any special software.

Here you have some commands:

#uname -a

what happens if you reboot with it plugged in? i had a usb drive that wouldn't mount but when i booted with it plugged in i never had problems after that.

I thing it must run without rebooting...

Sorry, but there were more messages with dmesg command:

What this appears to say is that your drive is detected and has been assigned to /dev/sda, which is typical for USB drives. You say you can't mount it using something like mount -t vfat /dev/sda /media/usbdisk/?

[rodogh]

It seems to be something in /dev/sda because of the line you've read

Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0

But waiting just some seconds it appears another lines telling that something is wrong... (just see my last post)

scsi: Device offlined - not ready after error recovery: host 2 channel 0 id 0 lun 0
scsi2 (0:0): rejecting I/O to offline device
usb 1-1: USB disconnect, address 13

So if I try to do what you said I get "no device" message (in spanish....)

mount: el dispositivo especial /dev/sda no existe

Kind regards !!!

Hi again,

just only to say that I restored a O.S's backup and now it runs perfectly. The problem ? I don't know...

If I do a dmesg this is what it happens:

scsi2 : SCSI emulation for USB Mass Storage devices

If anyone want to know about my new configuration, just let me know...

Thanks to you all...

Well, umm... YEAH! See, just like I said! I mean... umm..

But seriously, good to see it's working now, but I can't for the life of me figure out what might have gone wrong in the first place. Perhaps you updated a software package that conflicted with something else? I'm really shooting in the dark here, but good to hear it's working now.
