USB 2.0 Flash Drive with Mandrake 10
I'm new to this forum, and fairly new to linux, so I hope I ask my question correctly and with the right information. :D
Im having a small amount of trouble with a USB 2.0 flash drive with my Mandrake 10.
If I plug it in, and boot up, it is detected, it mounts and I can access the drive.
The problem is, the icon on the desktop does not give me the option to unmount the drive. Even when I 'umount /mnt/removable' and remove the drive and replug it, I cant get it working again. I have to reboot to make that happen.
I know I can hotplug things in my current system state as I can hotplug my camera and that gets detected and redetected.
I tried using Knoppix with the usb drive, and this automatically set up the drive to be unmountable. This works when I plug the usb drive back in and remount it. Under knoppix, the fstab line for the drive is:
/dev/sda1 /mnt/sda1 vfat noauto,users,exec,umask=000,uid=knoppix,gid=knoppix 0 0
So I'm thinking the problem is either the modules I have installed, or something is set up strangely..
And now for some printouts....
under sda in Harddrake2:
New devfs device: /dev/scsi/host0/bus0/target0/lun0/disc
Old device file: /dev/sda
Floppy format: DCS SOLID GEAR -USB2
Media class: hd (Mass Storage|SCSI|Bulk (Zip))
that seems correct to me.

Id really appreciate some help on this issue.
I've looked around the forums for solutions, but I couldn't find much in the way of re-plugging a usb device, mostly just mounting it.
Try changing the fstab to
/dev/sda1 /mnt/removable ext2,vfat noauto,umask=0,iocharset=iso8859-1,codepage=850 0 0
Then create a link
ln -s dev/scsi/host0/bus0/target0/lun0/part1 /dev/sda1
/dev/sda1 might already exist.
Thanks for that,
I added that line to the fstab,
but when I rebooted, I found that the line(s) I removed originally:
none /mnt/removable2 supermount dev=/dev/scsi/host0/bus0/target0/lun0/part1,fs=ext2:vfat,--,umask=0,iocharset=iso8859-1,kudzu,codepage=850 0 0
was replaced. I noticed that when I booted, sometime during the startup messages, a dialog box comes up with Harddrake saying a device was added.
So again, I can get the drive to work under /mnt/removable2, but I cant umount, unplug and replug the drive... :confused:
Could I have a service running, or something else configured wrong outside of the fstab file?
xxx_Birdman_xxx - I am just starting to dig into getting my SanDisk compact flash reader working in Mandrake 10. Some of the things I'm observing may shed some light on what you're seeing?
If I have "hotplug" service running or started, I get multiple "removable" type directories that create/disappear on their own in /mnt. If I disable hotplug, I only get /mnt/removable created/removed as I plug/unplug my reader.
I've been successful at disabling hotplug, rebooting my system with no USB devices attached, then after full boot up and log in, I checked my /etc/fstab. It has no references to "/mnt/removable".
Then, I plug in my USB reader and recheck /etc/fstab. A line magically appears with "/dev/scsi/host3/bus0/target0/lun0/part1 /mnt/removable auto umask=0,user,iocharset=iso8859-1,kudzu,codepage=850,noauto,exec 0 0"
The reason this fstab entry "magically appears" (I'm guessing) is because devfsd is what is really controlling /dev/sda1 on MDK 10?
At any rate, once this line appears in /etc/fstab, I can then type "mount /dev/sda1 /mnt/removable" and it mounts! But I can only access the mounted files as my root userid at this time... I'm still working on understanding that part.
So, in a nutshell, I can mount/unmount this device at will without rebooting the operating system and I only have one instance of /mnt/removable.
Coincidentally, no icons pop up on my desktop for "removable" and that's fine by me (for now). I can at least get to my cards data. Hopefully these ramblings help you figure out your card too!
