messed up my removable media!

[stevek123]

I've been trying to get help reading mp3 from my sandisk e260. Posted here once already and over at hardware too. I found a thread here http://ubuntuforums.org/showthread.php?p=4776609
and tried it. Now I cant even see it! I get an usb error msg icon in top rt that bubbles me with 'unable to get data'. When I go to System -> Pref -> Removable Media, I get an error message 'The hald service is not currently running - enable it' and it notes Linux kernel 2.6 is necessary to enable volume mgt. ???? How do I re-enable the hald? and synaptic doesnt list kernel 2.6 as one of the options (a patch yes but not whole thing). Help please.

How do I re-enable the hald?


ps -e | grep hal

will list if the process is running


sudo /etc/init.d/hal {start|stop|restart|force-reload}

will do one of the following things ^^


sudo fdisk -l

will list what your player is detected as


lsusb

will let you know if it is being detected at all, if its usb

I entered the codes in terminal and posted them below each line. Looks like a mess. What next? Uninstall hal at Synaptic and reload? (=my 1st guess)

[stevek123]

I found part of a fix for my issue here http://ubuntuforums.org/showthread.php?t=69419
I just did what 'bugsout' did and rebooted the system. It looks like everything is back to where I started. The funky rt corner error icon is gone, hald is back, I can open/use Sys-> Pref-> RemovableMedia, my mp3 player is recognized (microSD music there & base unit music NOT). I've no clue what happened but I think I mis-used graphical sudo (here http://www.psychocats.net/ubuntu/graphicalsudo ). At least I didnt mess my configs permanently or the mp3 player either. STILL looking for a way to break past the firmware and read mp3 music on the base unit.....

[kilroy423]

Sorry that I didn't get back sooner. You can't access your music because of firmware blocking it? You should be able to just mount that drive and access the music. Which goes like this.


sudo /etc/init.d/hal {start|stop|restart|force-reload}

You have to choose one of these: start, stop, restart, or force-reload. They are not all valid options at one time.

Im going to guess that that is your drive, since that is 2GBs.

and from


Bus 002 Device 015: ID 0781:7422 SanDisk Corp.

It is definently detecting your drive.




mkdir music_drive
sudo mount /dev/sdd1 music_drive
cd music_drive
ls music_drive


This should mount that device and then ls the contents of the drive. If mount is going to be picky, you can use


sudo mount -t vfat /dev/sdd1 music_drive

Good luck and let us know how it goes

Hi Kilroy
Thanks for late response - better late than never ;)

The 2G device is the added microSD card. Actually everything works there.
The actual Sandisk unit is a 4G device. I can read the folders on the Sandisk but ubuntu does not recog the contents of the music folder at all. As a noob to ubuntu and unfamiliar with terminal commands, I'm slow to process them....(fairly fluent in the gui tho...roll-over from windows). Anyway I'll try your commands and post what I get.

I think I missed some info with the big list I inset earlier. When the device is mounted, I get desktop icons for the sandisk and for the microdisk. The microdisk (reading fine) icon -> properties shows it as Fat16. The Sandisk shows as Sansa E200P and -> properties says it is Fat32. When I run sudo fdisk -l in terminal, I get this about the Sandisk...

Disk /dev/sdc: 4033 MB, 4033871872 bytes

This doesn't look like a partition table
Probably you selected the wrong device.

It looks to me like it does not see Fat32 anywhere - but does see Novell Netware 386 as a system in sdc2 partition = the firmware (I think).
When I try 'sudo mount /dev/sdc music_device' I receive a message

I'm almost 100% sure that you need to include the / in front of dev.
Here is the output of a test I ran on my machine.


dan@Laptop:~$ sudo mount /dev/sda Desktop/500/
mount: /dev/sda already mounted or Desktop/500/ busy

dan@Laptop:~$ sudo mount dev/sda Desktop/500/
mount: special device dev/sda does not exist


you can see that without the / it reports it not existing. Remember that you have to make the folder that you are trying to mount to. So if music_folder doesnt exist make sure you create it:


mkdir music_folder

FAT32 is recognizable by linux so I'm not sure what that output is that you are getting


but ubuntu does not recog the contents of the music folder

So you can navigate into the device and see the folders? Or is this another device?

I did some searching and thought you might want to have a look at this thread.

music folder still reads empty!

the / was there when I input the code. It was there the first time. Mounting is NOT the issue. Reading the contents of the folders is. Yes I can nav into the device and see the folders. Cannot see folder contents. jpgs in the photo folder or mp3s in the music folder. I believe the 4 partitions in the long list represent the 4 folders.

Other threads I've looked at including the ones you linked to me deal with mounting and read/write issues. I dont have those problems. I'm stuck!

FWIW - I went into the desktop icon after this last mounting and poked around. It shows I'm not owner/root and dont have any permissions to rw. The attached microSD card is root with rw tho. Attaching other flash drives also show up as root with rw. Its just this player...

when I looked in dmesg in terminal is says that sdc (sansa) has unknown partition table and does not assign it a partition label (i.e. sdc1) . The microdisk is recognized as sdd and is assigned a partition label of sdd1. Ubuntu doesnt like the formatting of the Sansa- tho it is listed as vfat (fat32) when I automount.

[kilroy423]

Mounting is NOT the issue. Reading the contents of the folders is.

Well, you can try and list the directory as root or you can try and see if those files are hidden.

as root

sudo su
cd music_folder
ls

for hidden files

ls -lha

Rats - tried that too... still no luck. Its gets as far as the folders in the player but then sees the folders as unmountable partitions (it sees/reads the drive mounted as sdc but then does not mount the partitioned folders-> sdc1, sdc2, ...). When I look/list folder contents, they still appear as empty...

I've a friend (the guy who steered me to the ubuntu world)... I am going to try and get him to crack into this thing. He's very good at this stuff and knows several programming languages, but runs everything from the command terminal and so is little help when messing with GUI issues. If I get a solution, I'll post it here. Thanks for staying with me Kilroy...
