Flash media problem

Blitzkreig75 · 02-27-2007, 01:46 PM

OK, I've gotten fstab setup correctly, (I think).

The card reader is connected to the motherboard, not a USB reader.

The Slackware FAQ instructed me to veiw dmesg |more for the location of my card reader devices and I found them to be sdb, sdc, sde, and sdf. I edtied fstab to look like this:

/dev/sd* /mnt/memory noauto,user,rw,umask=000 0 0 (where the * would be b-f)

I put a few cards in, and I can see the volumes in dsmeg, but I cannot mount the media. Dmesg says a few problems when viewing the info.

sdd "Invalid media value"
"can't find a valid file system"

sde "Bogus number of reserved sectors"
"can't find a valid file system"

sdf "Unknown partition table"

Now, if I understand right, if the info is only, like, a list of mp3's without a file system, I can't mount it, right? So, how can I get my media off of the flash?

I think I've got fstab setup right and when I "write" to it, I get a window(s) pop up about new media found giving me the option to open in a new window, but nothing comes up.

Slackware 11 2.6.17.13 kernel with "extra" modules installed.

Ststem specs are in my signature.

There is a filesystem on there, but there may also be partitions, might wanna try

'/dev/sd*1'

like '/dev/sda1'

Blitzkreig75 · 02-27-2007, 03:14 PM

Ok, Tex. I did just that, but still nothing.

I'm able to get the USB on the card reader working and accessable, (it has 4 multi-function slots and one USB), but the flash cards are what's giving me the problem.

The USB does not need any number after the sd* to work.

Do I need to make a simlink to each device, perhaps? I didn't for the USB drive, though.....

H_TeXMeX_H · 02-27-2007, 03:51 PM

Well, plug something in and check '/dev/disk/by-id', try mounting something in there.

Blitzkreig75 · 02-27-2007, 04:36 PM

OK, I've done that, but I'm a little confused asto mounting what I see.

This is what vim /dev/disk/by-id shws:

scsi-SSEAGATE_ST3366007LC_3JA033ZQ000023014BD2
scsi-SSEAGATE_ST3366007LC_3JA033ZQ000023014BD2-part1
usb-OTi_CF_CARD_Reader_0123456789abcdef
usb-OTi_MS_CARD_Reader_0123456789abcdef
usb-OTi_MS_CARD_Reader_0123456789abcdef-part1
usb-OTi_SD_CARD_Reader_0123456789abcdef
usb-OTi_SD_CARD_Reader_0123456789abcdef-part1
usb-OTi_SM_CARD_Reader_0123456789abcdef

EDIT: The two cards I have in (I think) are shown. One MS-Pro, and an SD card.

Looking at this, do I need to change the setting in fstab?

H_TeXMeX_H · 02-27-2007, 05:55 PM

well, you can mount the things you see there just like other devices ... they're really just symlinks to the right devices.

Code:

mount /dev/disk/by-id/usb-OTi_SD_CARD_Reader_0123456789abcdef-part1 /mnt/tmp

I suppose it is a bit confusing, but try to figure out which goes with which. Not sure about fstab ... you could change it in there if you want.

Blitzkreig75 · 02-27-2007, 06:48 PM

I am able to mount the cards, but only as root, (using that command), and only if there's one in the slot I specify, (I think the later is normal).

I've tried making simlinks, then re-writing to fstab, but still nothing. I tried /dev/flash, /dev/usbOTi, /dev/memory (where it's at now), but none are working. I keep getting the graphic about 'new devices found" but nothing is located when I 'open in new window' and the drives still cannot be mounted. I think I'm just doing something minor wrong.

Anything else I might try? I need the cards to work if I'm to complete my migration to Linux from XP. I have a lot of media I wish to keep, and using the card readers is a near-everyday thing for me so they have to work.

Blitzkreig75 · 02-27-2007, 07:27 PM

OK, I just tried mounting the sdd, (it's the one containing an SD card), as user, and I got "I could not determine the file sytem type and none was specified". Same result when trying to mount the MS Pro card.

H_TeXMeX_H · 02-27-2007, 08:14 PM

So have you tried mounting 'usb-OTi_SD_CARD_Reader_0123456789abcdef-part1' and 'usb-OTi_MS_CARD_Reader_0123456789abcdef-part1' ?

Blitzkreig75 · 02-28-2007, 07:34 PM

I tried both as root nad user, I tried "mout /mnt/usb-(etc...) and "mount /dev/usb-(etc..) and all attempts say "Cannot find device "...." in /mnt/fstab or /mnt/mstb

I also tried just " mount /usb-OTi_CARD..)etc..)" with the same result.

H_TeXMeX_H · 02-28-2007, 08:00 PM

Well, mount them to a place or it will say that.

So do:

Code:

mount /dev/disk/by-id/usb-OTi_SD_CARD_Reader_0123456789abcdef-part1 /mnt/tmp

(as I said earlier)

mount /source /destination

if you don't provide a destination it will look for one in /mnt/fstab or /mnt/mstb or give you "Cannot find device "...." in /mnt/fstab or /mnt/mstb.

Blitzkreig75 · 02-28-2007, 08:22 PM

ok, it's mounted, but I could only do it as root. I try as user and it says "Only root can do that"

But I'm still not getting into it in the desktop.....Ya think I need to make it "/usb-OTi_CARD_Reader_0123456789abcdef" in fstab?

BTW, I really appriciate your patience and help.

EDIT:

I have found the mounted /tmp in the desktop environment when loged into Xwindow as 'root' and I can see the jpeg and mp3 files. (Yay!!!). So now I need to know how to get them listed where to be able to get to them frm user's Xwindow without needing to temp munt the cards every time I wanna get data. I can get the data as user, too, but I wanna get the thing working properly, and be able to mount the cards as user, like I can do with the USB drive.

H_TeXMeX_H · 02-28-2007, 09:12 PM

You'd probably have to edit /etc/fstab

You might add:

Code:

/dev/disk/by-id/usb-OTi_SD_CARD_Reader_0123456789abcdef-part1       /media/sdcard   vfat         noauto,rw,umask=000,user  1  0

or something like that. Oh, and you can use /media/whatever as long as the directory exists.

Check here for more:
http://www.tuxfiles.org/linuxhelp/fstab.html
or here:
http://rkrishna.tp.googlepages.com/slackerbasics#usb

Now, I'm not sure exactly how KDE works ... because I don't use it ... but maybe someone else knows or search google or these forums.

Blitzkreig75 · 02-28-2007, 09:45 PM

Thanks, Tex. I've searched all over and can't seem to find anything specific to my delema. You have been the sole source of my help....and I truely thank you.

I can continue my migration now. There's a few more things I need to get working, but that can be another thread, prolly in a few days.

I'll fiddle with fstab and check the links.

Again, thank you very much for helping me get my data moving.

Oh, and btw, those two links did help me get the USB drive working, but not helping on the card issue.

H_TeXMeX_H · 02-28-2007, 11:13 PM

you can try

Code:

ls -l /dev/disk/by-id

that'll give you the exact links, so maybe if you put that it would work.

For example:

Code:

total 0
lrwxrwxrwx 1 root root  9 2007-02-28 08:16 ata-HITACHI_DK23EA-60_FG8339 -> ../../hda
lrwxrwxrwx 1 root root 10 2007-02-28 08:16 ata-HITACHI_DK23EA-60_FG8339-part1 -> ../../hda1
lrwxrwxrwx 1 root root 10 2007-02-28 08:16 ata-HITACHI_DK23EA-60_FG8339-part2 -> ../../hda2
lrwxrwxrwx 1 root root  9 2007-02-28 08:16 ata-SONY_DVD_RW_DW-U50A_EA472EA9 -> ../../hdc
lrwxrwxrwx 1 root root  9 2007-02-28 14:16 usb-Sony_USB_Memory_Stick_Slot -> ../../sda

So my memory stick is really at '/dev/sda' (but more likely it will mount from /dev/sda1 when I have stick in there (which is not now otherwise it would say usb-Sony_USB_Memory_Stick_Slot-part1 and sda1))

You can also notice hda1 and hda2 for my HDD, that's because I have 2 partitions (swap and root). I cannot mount /dev/hda because it is not a partition, I can mount /dev/hda1 and /dev/hda2. Similarly I can mount /dev/sda1 but not /dev/sda.
