Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, I have an ORB drive I am accessing using the usb-storage driver. I formatted the drive media last night using Windoze 98. The media was formatted as though it had one large partition, which is weird because I had previously partitioned the drive under Linux 2.4.0-test10 with several partitions. The Windoze format utility did not notice those partitions and simply (I thought) wrote one large partition and formatted it as VFAT. I have successfully written and read data on the media using two separate Windoze 98 machines. When I mounted the drive under 2.4.0-test10 and then looked at the media with fdisk, here's what I see: #> fdisk /dev/sda Disk /dev/sda: 68 heads, 62 sectors, 1021 cylinders Units = cylinders of 4216 * 512 bytes Device Boot Start End Blocks Id System /dev/sda1 ? 455397 584533 272218546+ 20 Unknown Partition 1 has different physical/logical beginnings (non-Linux?): phys=(356, 97, 46) logical=(455396, 22, 59) Partition 1 has different physical/logical endings: phys=(357, 116, 40) logical=(584532, 18, 23) Partition 1 does not end on cylinder boundary: phys=(357, 116, 40) should be (357, 67, 62) /dev/sda2 ? 315509 443350 269488144 6b Unknown Partition 2 has different physical/logical beginnings (non-Linux?): phys=(288, 110, 57) logical=(315508, 39, 57) Partition 2 has different physical/logical endings: phys=(269, 101, 57) logical=(443349, 17, 52) Partition 2 does not end on cylinder boundary: phys=(269, 101, 57) should be (269, 67, 62) /dev/sda3 ? 127844 459524 699181456 53 OnTrack DM6 Aux3 Partition 3 has different physical/logical beginnings (non-Linux?): phys=(345, 32, 19) logical=(127843, 53, 18) Partition 3 has different physical/logical endings: phys=(324, 77, 19) logical=(459523, 53, 49) Partition 3 does not end on cylinder boundary: phys=(324, 77, 19) should be (324, 67, 62) /dev/sda4 * 330795 330800 10668+ 49 Unknown Partition 4 has different physical/logical beginnings (non-Linux?): phys=(87, 1, 0) logical=(330794, 2, 36) Partition 4 has different physical/logical endings: phys=(335, 78, 2) logical=(330799, 6, 44) Partition 4 does not end on cylinder boundary: phys=(335, 78, 2) should be (335, 67, 62) Partition table entries are not in disk order When I try to mount the drive, I get the common error: mount -t vfat /dev/sda1 /mnt/orb1 mount: wrong fs type, bad option, bad superblock on /dev/sda1, or too many mounted file systems What's going on here? It seems to me that this is a bug in the Linux test10 filesystem support, since Windoze can read and write to this drive currently. Our implementation should be compatible.
