i have a problem with the following device: ugen7.2: <Meizu Electronics> at usbus7 umass0: <Meizu Electronics MiniPlayer, class 0/0, rev 2.00/1.00, addr 2> on usbus7 umass0: SCSI over Bulk-Only; quirks = 0x4400 umass0:7:0:-1: Attached to scbus7 da0 at umass-sim0 bus 0 target 0 lun 0 da0: < > Removable Direct Access SCSI-2 device da0: 40.000MB/s transfers da0: 3864MB (7913472 512 byte sectors: 255H 63S/T 492C) i haven't used it for quite a while, but it used to work just fine (yes with usb2). but since then i've updated my kernel a couple of times and now i'm getting these errors. i can mount the device just fine, but if i try to copy files onto it i get the following error messages: Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=54083584, length=65536)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=54149120, length=65536)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=54214656, length=65536)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=54280192, length=32768)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=54312960, length=16384)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=54329344, length=65536)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=54394880, length=65536)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=54460416, length=65536)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=54525952, length=65536)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=54591488, length=65536)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=54657024, length=16384)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=512, length=512)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=24576, length=4096)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=28672, length=4096)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=1024000, length=4096)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=1028096, length=4096)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=38502400, length=16384)]error = 5 Jul 28 11:22:07 otaku kernel: g_vfs_done():da0[WRITE(offset=39370752, length=16384)]error = 5 Jul 28 11:22:07 otaku kernel: fsync: giving up on dirty Jul 28 11:22:07 otaku kernel: 0xcc0aa6b8: tag msdosfs, type VREG Jul 28 11:22:07 otaku kernel: usecount 1, writecount 0, refcount 55 mountedhere 0 Jul 28 11:22:07 otaku kernel: flags () Jul 28 11:22:07 otaku kernel: v_object 0xc8a81770 ref 0 pages 212 Jul 28 11:22:07 otaku kernel: lock type msdosfs: EXCL by thread 0xcc60a240 (pid 19448) Jul 28 11:22:07 otaku kernel: #0 0xc05b5ee0 at __lockmgr_args+0xb90 Jul 28 11:22:07 otaku kernel: #1 0xc0647898 at vop_stdlock+0x68 Jul 28 11:22:07 otaku kernel: #2 0xc0781fb5 at VOP_LOCK1_APV+0xb5 Jul 28 11:22:07 otaku kernel: #3 0xc0664008 at _vn_lock+0x78 Jul 28 11:22:07 otaku kernel: #4 0xc0658adb at vget+0xbb Jul 28 11:22:07 otaku kernel: #5 0xc055d4ca at msdosfs_sync+0x17a Jul 28 11:22:07 otaku kernel: #6 0xc06520be at dounmount+0x44e Jul 28 11:22:07 otaku kernel: #7 0xc065262f at unmount+0x2bf Jul 28 11:22:07 otaku kernel: #8 0xc076eb26 at syscall+0x2a6 Jul 28 11:22:07 otaku kernel: #9 0xc0752ad0 at Xint0x80_syscall+0x20 Jul 28 11:22:07 otaku kernel: startcluster 2230, dircluster 2229, diroffset 96, on dev da0 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=53805056, length=65536)]error = 5 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=53870592, length=65536)]error = 5 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=53936128, length=65536)]error = 5 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=54001664, length=65536)]error = 5 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=54067200, length=65536)]error = 5 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=54132736, length=65536)]error = 5 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=54198272, length=65536)]error = 5 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=54263808, length=65536)]error = 5 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=54329344, length=65536)]error = 5 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=54394880, length=65536)]error = 5 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=54460416, length=65536)]error = 5 Jul 28 11:22:40 otaku kernel: g_vfs_done():da0[WRITE(offset=54525952, length=65536)]error = 5 might the device's ram be broken? this is the result of `dd if=/dev/da0 of=/dev/null`: dd: /dev/da0: Input/output error 1067+0 records in 1067+0 records out 546304 bytes transferred in 235.522107 secs (2320 bytes/sec) i attached the device to a windows xp box and ran scandisk. that didn't reveal any problems however. cheers. alex oh...and i'm running r195923.
