Jumpdrive issues

hey guys,

Ok I just installed open suse 10.2 about a couple of months ago. And for some weird reason I can't get my any of my jump drives to be able to write. When they worked just fine on OpenSuse 10.1? I can read and be able to download what is off of them. But the min I write to them and try download the file, it is either a file with the name and 0kbs. or its not even there. so does anyone have any ideas? Oh I also tried writing the the jump drive in root mode, and that didn't work.

Thanks

What file system type do the drives use? Is it NTFS? If the drives use the NTFS file system then your computer may be mounting them as read-only. You can see how the drives are mounted by issuing the mount command in a terminal window.

Code:

mount

Try to write to one of the drives then read the /var/log/messages file. There should be a helpful error message.

Code:

tail /var/log/messages

You will need to be root to read the file.

ok here is what I get on typing mount.

Code:

/dev/hdb2 on / type ext3 (rw,acl,user_xattr)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
debugfs on /sys/kernal/debug type debugfs (rw)
udev on /dev type tmpfs (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
/dev/hdb3 on /home type ext3 (rw, acl, user_xattr)
securityfs on /sys/kernel/security type securityfs (rw)
/dev/sdb1 on /media/disk type vfat (rw,nosuid,nodev,noatime,udi=1000,utf8,shortname=lower)

So the bottom one is the USB one and it appears to be running in fat.

Code:

/dev/sdb1 on /media/disk type vfat (rw,nosuid,nodev,noatime,udi=1000,utf8,shortname=lower)

Now when I tried writing to the jump drive. I learned something new but still in the same boat. What I 1st tried was I plugged in the jump drive. Right clicked in the window with all of my files told it to create a text file, wrote stupid stuff in the file and saved it. Unplugged the jump drive, plugged it back in and text file is still there. Went to another computer plugged it in, and hey text file is still there. Then I tried writing to the jump drive again, with bigger files. Like my webpages, copied the webpage I have been trying to save on the jump drive for a while now, and unplugged and pugged back in hey what do you know, webpage with file names and 0kbs. Here is what I got when tail /var/log/messages

Code:

kernel: sd 11:0:0:0: Attached scsi generic sg1 type 0
kernel: Vendor: SanDisk Model: U3 Cruzer Micro Rev: 2.15
kernel: Type: CD-ROM
kernel: sr0: scsi3-mmc drive: 8x/10x writer xa/form2 cdda tray
kernel: sr 11:0:0:1: Attached scsi CD-ROM sr0
kernel: sr 11:0:0:1: Attached scsi generic sg2 type 5
kernel: usb-storage: device scan complete
kernel: cdrom: This disc doesn't have any tracks I recognize!
kernel: cdrom: This disc doesn't have any tracks I recognize!
hald: mounted /dev/sdb1 on behalf of uid 1000

It sounds like your system is working. If you want to have the partition automatically mount on a different mount point then you could add a line to /etc/fstab such as the following. The line here is to automatically mount /dev/sdb1 on /mnt/sdb1 regardless of file system type.

Code:

/dev/sdb1   /mnt/sdb1  auto   defaults   0   0

The word "auto" means that Linux has to figure out what type of file system is on the partition. That way you could have a different disk with a different file system type and this line would still work.

The word "defaults" means to use default mount options. These are things like read-write, nosuid, noexec, and other mount options.

The two zeros tell Linux not to automatically perform a file system check when the partition is mounted.

I'm glad to hear that you're able to use your disk now.
