SanDisk USB stick with FreeBSD 7
Hi, I've gotten an USB stick with 8 GB which doesn not work with FreeBSD 7-STABLE-20080811. I've googled and found that this particular product might be defective by factory. Anyone has an idea how to make it accessible with FreeBSD? In order to have maximal abilities for data transfer, this stick is msdosfs formatted. But no proper device will occur if plugged in. Some data here: umass0: SanDisk Cruzer Micro, class 0/0, rev 2.00/2.00, addr 2 on uhub3 da0 at umass-sim0 bus 0 target 0 lun 0 da0: SanDisk Cruzer Micro 8.02 Removable Direct Access SCSI-0 device da0: 1.000MB/s transfers da0: Attempt to query device size failed: UNIT ATTENTION, Medium not present umass0: at uhub3 port 1 (addr 2) disconnected (da0:umass-sim0:0:0:0): lost device (da0:umass-sim0:0:0:0): removing device entry umass0: detached There is only /dev/da0. % fdisk da0 *** Working on device /dev/da0 *** parameters extracted from in-core disklabel are: cylinders=977 heads=255 sectors/track=63 (16065 blks/cyl) parameters to be used for BIOS calculations are: cylinders=977 heads=255 sectors/track=63 (16065 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 11 (0x0b),(DOS or Windows 95 with 32 bit FAT) start 44, size 15679396 (7655 Meg), flag 0 beg: cyl 0/ head 0/ sector 45; end: cyl 975/ head 254/ sector 63 The data for partition 2 is: UNUSED The data for partition 3 is: UNUSED The data for partition 4 is: UNUSED Sothe partition data can be read, why is there no device file to access the partition? because of the line da0: Attempt to query device size failed: UNIT ATTENTION, Medium not present I think it's not possible to get rid of this problem by reformatting the stick. I think about returning it to the vendor with a hardcopy of dmesg which reveals that the stick is defect. :-) Thanks for any recommendations. -- Polytropon From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

No problem. I used to have one of these and it worked with Windows, FreeBSD 6.x and even 7.x until one day I broke it with my carelessness. When I got you correctly, this means that it *should* work with FreeBSD 7 without any magic done to the system? Please get me right: If I need some modification on my 7.x system to make it work, I still can't use the stick on my 6.x and 5.x systems, so it would be useless. It should (have) work(ed), yes, like this: mount_msdosfs /dev/da0s1 /mnt Exactly, this is what I expected, and which worked with other Windows formatted USB sticks in the past. But due to not having /dev/da0s1... allthough fdisk da0 showed the partition... no luck. But as you can see, yours has problems.. as appears in dmesg. Okay, now I am sure to have something defective. I'll return it with a dmesg hardcopy. -- Polytropon From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I think so, too. FreeBSD relies on correctly working devices, and it checks for this. The strange thing was that I could read the partition table via fdisk da0. To be sure, I've tried the stick on the USB 1.0 controller (message above) and on the USB 2.0 controller of the mainboard, with similar result: umass0: SanDisk Cruzer Micro, class 0/0, rev 2.00/2.00, addr 2 on uhub2 da0 at umass-sim0 bus 0 target 0 lun 0 da0: SanDisk Cruzer Micro 8.02 Removable Direct Access SCSI-0 device da0: 40.000MB/s transfers da0: Attempt to query device size failed: UNIT ATTENTION, Medium not present if you can - check it on another computer running other OS (linux, windoze) On Windows PC, the stick has been accessible, but Properties showed a minimum disk space occupation (circa 300 kB) allthough there was nothing on the stick. Linux: Not invented here. :-) -- Polytropon From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
