Re: USB memory stick and flashcard mount failure
Thanks to all who responded to my original post. The problem is apparently that USB memory sticks and flash cards (and probably other external memory cards) often have unique formatting that is understood by Windows but not by Linux. The best solution suggested so far (from Juha Tuuna, shown below) is to zero the device, and then partition and reformat it. This installs a more standard VFAT format on the device. I don't have the vfat option for mkfs on my Linux setup so I did the zeroing and partitioning with Linux and then the formatting with Windows. Devices now work fine with both systems and, for the flash card, still work in a Canon Powershot digital camera. Should note that if the usbmount package is installed, then fstab doesn't need to be changed and a mount command is not needed. The device mounts automatically when inserted into the USB port. This on Debian Sarge plus kernel 2.6.8. Herb Juha Tuuna wrote: On Friday, 12.

Thanks, Herb I had exactly the same problem. I copied the files on the Windows box, inserted the stick into the Debian box and zeroed the whole stick (/dev/sda) dd if=/dev/zero of=/dev/sda Then I created a single primary partition with cfdisk on the usb stick cfdisk /dev/sda formatted it mkfs.vfat /dev/sda1 and copied the files back. At the moment the stick works fine under both Debian and Windows XP. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

If you have the kernel source, I don't, you might look through the Documentation directory for some mention of SD cards. There may be a kernel option for them(?). I have never tried reading SD cards myself. BTW Take a look at the Netiquette thread. I am subscribed to this list and have no need of a Cc.

This occurs with both a Memorex Traveldrive and a Compact Flashcard in a Flashcard-to-USB adapter. Both devices work fine with Windows XP which also verifies that a FAT filesystem is on these devices. The only advice I've found online is to reformat the USB devices. But these are devices from other people that I cannot reformat. Is there something I can add to the fstab line or the mount command to recognize the vfat file system on the USB devices? The problem with the TravelDrive is the proprietary format Memorex uses for their idiot software. They've basically built a little static filesystem within a filesystem there that behaves like a live CD when it loads on a windows box - this is marketing bs for selling proprietary software. You might try mountint that little portion of the drive first to get it accounted for, then mounting the data portion in another location. I bought two of the damn things without realizing, and played hell for awhile until I found this out. But they were mine, so I zero'd 'em and slapped ext2 on. Great ever since.
