Just today when plugging in my U3 ClvrStuff USB Flash Drive i received the error "The Disk you inserted is not readable by this computer", i pressed Initialize and from then onwards it gradually went downhill. Both Data Rescue 3 and DiskWarrior 4 were unable to save my USB flashdisk and unfortunately i was left with having to completely reformat, a few times also on Zero Out Data. Currently operating a MacBook Pro version 10.6.7, the problem has not gone away. One of the intermediate steps i carried out was to reformat into MacOS Extended (Journaled) and then rebuild the USB by using DiskWarrior. The Graph has reported 28/108 errors with the blue graph underneath showing an "un-optimized" disk. This was then reformatted again into FAT32 using Disk Utility. Upon ejecting and remounting the USB i always get the error: "The disk you inserted is not readable by this computer" with the options only to Ignore and Eject. I have checked Console and this is what comes up around the time of the error. 23/05/2011 18:52:42 fseventsd could not open <</Volumes/DISKNAME/.fseventsd/fseventsd-uuid>> (No such file or directory) 23/05/2011 18:52:42 fseventsd log dir: /Volumes/DISKNAME/.fseventsd getting new uuid: 4193C981-354D-4FB3-AA6B-CF7DC87D8E16 23/05/2011 18:52:42 mds (Normal) DiskStore: Creating index for /Volumes/DISKNAME 23/05/2011 18:53:18 kernel USBMSC Identifier (non-unique): 0B604B615222995B 0x8ec 0x20 0x200 23/05/2011 18:53:19 fseventsd check_vol_last_mod_time:XXX failed to get mount time (25; &mount_time == 0x10037f8b8) 23/05/2011 18:53:19 fseventsd log dir: /Volumes/DISKNAME/.fseventsd getting new uuid: 0E213259-9297-40F3-A6E0-876696996E23 23/05/2011 18:53:22 kernel SAM Multimedia: READ or WRITE failed, SENSE_KEY = 0x00, ASC = 0x00, ASCQ = 0x00 23/05/2011 18:53:22 kernel SAM Multimedia: READ or WRITE failed, SENSE_KEY = 0x00, ASC = 0x00, ASCQ = 0x00 23/05/2011 18:53:22 kernel SAM Multimedia: READ or WRITE failed, SENSE_KEY = 0x00, ASC = 0x00, ASCQ = 0x00 The SAM Multimedia errors continue and repeat for a little while until this then comes up 23/05/2011 18:53:22 kernel disk2s0: I/O error. I am unsure what to do to prevent these errors from showing up anymore, or is there no such method to repair my USB. I am not interested in the restoring of any files or anything as i've lost them all anyway, but simply a method of stopping the problem. Any help is appreciated, thank you.
