Problem writing to USB pendrive

Choucete · 07-23-2008, 06:52 PM

Hi,

I'm not sure if this is the correct forum to post this, but since I'm 100% Slackware, here I am.

I’ve been for quite some time now trying to fix an issue I have with my pendrive. Basically, I can read information from it but I cannot write to it not as a normal user nor as root.

I’ve been googling around and I also reviewed several threads from this forum and made adjustments to my fstab file but I wasn't able to solve the issue. Could you please provide any pointers?

This is my fstab as it is currently set:

/dev/hdc2 swap swap defaults 0 0
/dev/hdc1 / ext3 defaults 1 1
/dev/hdc3 /home ext3 defaults 1 2
/dev/hdd /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/sda /mnt/usbdev auto umask=0,user,iocharset=iso8859-1,codepage=850,noauto,quiet 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

with root powers edit your fstab as follows...there is more than way but its a simple one to try

1) assuming /dev/sda is the usb?...delete that line

instead you need an entry to mount a partition rather than mount the entire device so

2)
I prefer a new folder so

Code:

mkdir /mnt/pen

then in fstab
/dev/sda1 /mnt/pen (filesytem) users,rw 0 0

replace (filesystem) with the format of the usb device...if its a ms compatible one its likely to be
vfat

but mine is formatted as xfs so I have some forgiveness if the power fails.

eg
/dev/sda1 /mnt/pen vfat users,rw 0 0

3) users allows anyone versus user meaning root
rw means read write

Great. Thanks aus9! I'll try that when I get home (I'm at work right now, where I'm forced to work under win

).

But I have one more question, my pendrive is formatted as FAT32 (I had it as ntfs but I lost all the data in it a couple of times), so (nOOb question alert) setting fstab to vfat will recognize and read the device as FAT32?

Thanks again

aus9 · 07-24-2008, 01:29 AM

should do...vfat means fat32

do you have to use it in a windows computer?

xfs or ext3 is a much safer format for usbs....one because I do not like the journal function of ntfs and fat32 well thats not journalised so if power failure you have probs.

since you already lost data on ntfs...there is another way

if big enough create 2 partitions
1...fat32
2 xfs or ext3

good hunting

Hi again, I'm sorry to say that what you suggested didn't work either. In fact, the pendrive wasn't detected as /dev/sda1, I had to set it back to /dev/sda to get at least to read from it.

Could it be a hardware issue? Or might the fact that the pendrive is actually attached to a USB Hub be causing trouble? (Now that I think of it, I haven't tried to attach the pendrive directly to the machine, I'll try it today).

Do you have any suggestions?

BTW - I use the pendrive a lot between Linux and Windows, because none of the people I know has Linux as their system. And I've been able to get data out of my linux box on cd, but I'm not comfortable being unable to understand and solve this.

Just in case, here is the output of dmesg:

3 things interest me...others feel free to point out other issues

end of output you have sda unknown partition table

2) hub looks ok by this line (not all in same area)
usbcore: registered new interface driver hub and

.....but hub 1-1:1.0: 100mA over power budget!

3) and towards the bottom
kobject_add failed for usb_storage with -EEXIST, don't try to register things with the same name in the same directory.

suggest you try re-doing your hub pls

well I would recommend to copy all the stuff from it to hard drive and then repartition it under linux
mine looks like this:

That is almost definitely because the huge-smp kernel is being used instead of the generic-smp kernel (see CHANGES_AND_HINTS.TXT on your install CD/DVD or at your favourite mirror). I would recommend switching to the generic-smp kernel (which requires an initrd [aka an initial ramdisk]), but that most definitely does not have any effect on this problem.

As stated above, you should try accessing the drive without a USB hub in the way. You may also wish to try backing up the drive and repartitioning/reformatting it as FAT32. Since you're attempting to use fstab to mount the device you are not required to be in the plugdev group. However, if you would prefer an automated solution, you can always automount through HAL (which requires that your user is part of the plugdev group). If you use KDE or XFCE (or Gnome if you have installed it), plugging in a USB drive will allow you to mount it graphically instead of struggling with a permanent mount point in fstab. However, either method is acceptable. If you want to use automounting, add your user to the plugdev (and cdrom, video and audio groups for unrelated reasons) using the following command:

Code:

gpasswd -a username plugdev

Sorry for the delay to reply to you guys, but I just moved and I've been busy with that for the last couple of weeks.

I tried plugging the pendrive to the machine without the USB Hub and it works. I was able to write to it without any issues.

Thanks a lot for your help everyone!
