  • Upgrade to 10.4.7, now USB flash drive isn't recognized

    I upgraded to 10.4.7 the other night, but the installation was interrupted. Apple Support got the machine up and running by doing a safe boot and removing some corrupted start up files.
    Problem is that my USB memory key isn't recognized. It works fine in my iBook, but not in the iMac.
    It appears in the System Profiler as a "Flash Disk", but does not appear in the Disk Utility.
    iMac Intel 20"   Mac OS X (10.4.6)   Upgraded to 10.4.7

    I have an expanded problem now -- I still can't get the system to recognize the flash drives, and it won't recognize my digital camera, either. Oddly, it starts iPhoto, but it doesn't see the camera.
    I've tried all the erasing tips with the flash drives, but they didn't work.
    There is nothing in either System Profiler or Disk Utility identifying the camera.
    Otherwise, the system runs great. And the keyboard and mouse work fine.
    Any ideas?

  • Flash drive does not appear in Finder or on desktop

    When I plug a flash drive into my iMac, it sometimes does not show up in Finder or on the desktop (or if it shows up when I plug it in, it disappears after awhile). As a result, I am unable to eject it properly, and when I physically disconnect it a message appears telling me I removed it improperly and may have corrupted my data. Another discussion thread said to go into Finder> Preferences and choose to show CDs, DVDs and iPods on the Desktop. I had already done this, so there must be another solution. Any help?

    launch *disk utility* (in applications > utilities). if DU can see the drive, try repairing it.
    perhaps reformatting the drive for Mac (make sure the partition map scheme of the USB drive is GUID or Apple Partition Map (APM) and the volume format is Mac OS extended (journaled)) will bring it back to its senses.

  • My flash drive isn't showing up on my Mac. How do I find it?

    I need to get a file off my flash drive and onto my mac. I plugged it in and it isn't showing up. I checked the finder window, as it has been there before but its not there. My flash drive is working, as I can open it on our other comp.

    Click on the Desktop and go to Finder>Preferences>General tab and make sure 'External Disks' is ticked under devices. Do the same on the Sidebar tab if you'd like it to show there as well.

  • My USB Flash Drive isn't recognised?

    Today, when using my Macbook with Mac OS X Tiger (10.4.11), suddenly it did not recognize my Verbatim 4GB USB flash drive. What's strange is that when I plug it in, the light on the flash drive blinks as if the computer has connected to it, but it doesn't show up either on the desktop or in Finder. I have tried both USB ports on the side of my Macbook.
    I have tried shutting down my computer and restarting, but nothing has happened. I also know that the flash drive works properly because I plugged it in to my PC and it was recognized. Another thing is, that my Macbook does recognize both my Memorex and Scandisk flash drives perfectly normal. Up until today, there have been no problems with this device. Can anyone help me on this topic? Thanks.

    A few things to check:
    - If you launch Disk Utility does the flash drive show up there as a volume? I once had my iPod do the exact same thing as your flash drive and when I opened Disk Utility it mounted the iPod volume within seconds.
    - If you go into System Profiler does it show the drive being seen through the device tree under USB? The fact that it appears to be drawing bus power is definitely a good indicator.

  • My external hard-drive isn't appearing on my laptop?

    Both the laptop and hard-drive are new and had worked previously. I was using it as my external back-up and was working fine as my time machine. But now it isn't appearing at all on the computer anywhere. The hard-drive is still working, that is the light is on, it is making noise like it normally would, and when plugged into another mac it shows up fine, it's just my laptop? Can anyone help? Thanks!!

       The point is that the HD is working with another computer,
    That doesnt mean anything actually, seen that often, read the link above, ....
    Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
    People logically often think thats the case, but when a SATA card fails, it often, due to power faults will work on another notebook USB port and not on another.
    last test, verify that another HD wont connect to your USB ports on your Air.
    .......if it does, its a bad SATA card on the HD.

  • "Removable Disk" shows up in Windows 7 even when USB Flash drive isn't there

    I have a new windoz 7 computer, a couple of new sandisk cruzer 16bg flash drives. I removed the flash drives a couple of times without doing the "eject" thing. I never had a problem with your flashdrives on my xp machines. I know I was a bad boy, I just pulled the usb flash drive out. When I go to my computer folder it shows me my hard drives and its shows 5 Devices with Removable Storage ....one of which is the DVD RW Drive and 4 Removable Disk  which are or were times when I plugged in my usb flash drive. They show 0 bytes, nothing is in any of the "Removable Disk" instances and I cannot remove them. I tried to delete, cut and I tried to eject but the Removable Disk icon stays there. How can I get rid of these safely, I tried rebooting a couple of times, they show up even without any usb devices plugged in. Thanks in advance Scott

    I had this same problem.  It turns out to be easy to resolve:Open the Windows 7 "Start" Menu,  on the right shoose computer, in the new window that opens choose System Properties from the choices across the top of the window, now on the left side of the window choose Device Manager.  In Device Manager expand the "Disk Drives" entry.  You should see a listing of your hard disk drives and you'll also see "removable disk drives" with some additional idnetifying information.  Select the offending entry and then right click and select "Uninstall" click "Okay" and the entry will be gone.  Just be sure you're not uninstalling one of your hard disks.  That's all there is to it. To prevent this issue in the future always "eject" the SD drives/sticks before you remove them. I hope this helps.

  • My flash drive won't appear on my iMac; "Devices" doesn't appear on my Finder.

    The Support information posted so far doesn't help; Finder does not bring up any external devices at all (Printer, Time Machine, flashdrive).

    Have you set Finder preferences to show external disks?
    FWIW, I've not seen printers showing on the desktop and know of no way to set it up to do so.

  • MSI P965 Neo-F (MS-7235) problem booting from USB flash drive

    Hi, all!
    I was wondering if someone can help me. I am trying to install Windows 7 x64 on my 320GB HDD that is connected to my MSI P965 Neo-F (MS-7235) mobo (The CPU is a Core2Duo 6600 with 6GB of RAM). I created a bootable USB 8GB flash drive using Microsoft's "Windows 7 DVD USB Download Tool" and bootsect.exe (Needed to create a boot sector on the USB drive) from the MS store. I successfully tested the resulting bootable USB drive using freeware MobaLiveCD (Sorry, you'll have to Google "mobalivecd" since this forum doesn't seem to allow external links) running under Windows XP SP3 x86 (32bit). Under MobaLive's QEMU, Windows 7 setup loaded its files and produced an error message basically saying that it could not install Windows 7 x64 under an x86 OS (No surprise there since QEMU is emulating a 32bit processor - The point is that the bootable USB drive I created works).
    I then went into my mobo's CMOS and under Advanced BIOS Features -> Boot Sequence -> 1st Boot Device, set the value to "USB-HDD" and rebooted my machine. The USB drive probably was not detected by the mobo under that setting because it proceeded to boot from my HDD which is the 2nd Boot Device. I repeated the same process using each one of the  four USB ports in the rear of the mobo (I don't have the optional USB panel that the MSI users manual mentions) to no avail. I also tried setting the 1st Boot Device to "USB-FDD" and repeated the process for each USB port but the mobo still will not boot from the USB drive (It does not recognize it). When I set the 1st Boot Device to "USB-ZIP" and rebooted, the mobo hangs after "Verifying DMI Pool Data ..." which is no surprise since I am not using a USB ZIP drive but a USB flash drive. It appears that under that setting, it recognizes that there is a USB device attached but it is expecting a response (From a USB ZIP drive). I had no idea it would be this frustrating to boot from a USB flash drive! If anyone knows how to make this mobo boot from a USB flash drive, please let me know. Any assistance would be greatly appreciated. Thanks!

    The P965 Neo motherboard is 8 years old, so don't expect miracles. .... You need to format the USB stick in the proper way. You may use this utility to do it: hxxp://www.prime-expert.com/flashboot/ Also, it's a good idea to use the first (USB0) connector (controlled by Intel ICH8) for the USB flash drive. Good luck.
    Thank You for your fast response, RemusM!
    I'm not looking for a miracle. I'm just looking for a mobo that does what it is supposed to do: Allow me to boot from a USB flash drive (I don't think that is too much to ask for even from a board that was made in 2006)!
    Thanks for recommending FlashBoot. I see under their "Why FlashBoot" section that it "... does not shift to user the burden of choice between "USB-ZIP" and "USB-HDD" at format time and proper BIOS setup at boot time. ... and every USB disk is formatted in such way that it will work in every environment properly, regardless of current BIOS setting.", so I will give it a try and let you know about the results afterwards.

  • Flash Drive Not Recognized

    I have an 8GB flash drive that worked until last night. I was uploading a 3.6 GB file and it crashed. I tried using Disk Utility to reformat the drive, but then that crashed too, along with Finder. I had to hold the power button to shut down my computer.
    Now my flash drive isn't recognized by my Mac and does not come up with Disk Utility. I tried using it on a PC and the PC realized it was inserted but it was not recognized.
    HELP!

    It's not the power in the ports because other USB devices still work without a problem.
    Missed the part where you told us that. 8^)
    Then format it on the PC and bring it back to the Mac.

  • USB Drive Doesn't Appear Anywhere

    This flash drive isn't visible on the desktop, in the finder, in Disk Utility. I know if I eject it by just pulling it out, I will get the message that it may have been damaged. I don't know what to do. Any ideas?

    In Finder, Finder menu, Preferences, General, Show these items on the desktop.  Put a check mark in External Disks.  (And the others, if you also want them visible.)
    ...in Disk Utility...
    If it isn't visible in Disk Utility, then you may have other issues with the flash drive.  Have you tried a different flash drive on the same computer?  The same USB port?  Have you tried the non-mounting flash drive on a different Mac?  (Or PC, if it's in a compatible format.)  If it's not showing up at all, you may have no choice except to pull it out.  If you're really worried, then you can shut down your Mac before pulling out the flash drive.  (Shut down, not sleep.)  That will ensure that the Mac will close and unmount the drive as best it can.

  • How to boot from usb flash drive on Satellite A500-o25

    How do you configure boot order on A500-o25 so that it boots from usb drive first.

    Hi,
    Enter the Bios, pressing F2 on startup, go to the Boot menu and choose Usb drive as the first boot device (you navigate with F5 and F6 keys). Press F10, and ..Save and Exit menu ,, appears, press ok. That's all.
    Note, on my satellite A500, I have to connect the Usb flash before to turn computer on, otherwise the usb flash drive doesn't appear in boot menu in Bios

  • Unable to mount flash drive w/ OS 9.2.2 and Powerbook G3

    I've upgraded my G3 Pismo up to OS 9.2.2. However, the system won't mount a USB flash drive.
    Here's a breakdown of the problem(s):
    1) Insert flash drive, but flash drive won't appear on desktop.
    2) Check System Profiler, and system freezes.
    3) Remove flash drive from USB hub, and system unfreezes. System Profiler now has a listing for "Sandisk Cruzer Mini" in the USB -- even though the flash drive is no longer there.
    4) Check extensions. There is no USB Mass Storage Support extension. Download from Apple site, the USB Mass Storage Support 1.3.5 extension.
    5) Attempt to install this extension. Won't let me do it. Gives the message "This program cannot be run on your computer. See the documentation for details."
    6) Check documentation. I have the requisite system: Powerbook G3 and OS 9.2.2.
    7) Attempt to reinstall OS 9.2.2, as perhaps that might fix the problem.
    8) Cannot re-install OS 9.2.2. Gives the message: "The application program 9.2.2.smi etc. cannot be opened because an error of type -39 occurred."
    9) Clueless at this point.

    Hi, BGBchewy -
    Re the USB Mass Storage Support item, the ReadMe that accompanies it and comprises the info on the download page states -
        "Requirements
        Mass Storage Support 1.3.5 requires Mac OS 8.6. You do not need to install this software if you have installed Mac OS 9."
    Ditto the later version of that software, USB Adapter Card Support 1.4.1.
    This user Tip may provide the assistance you need -
    http://discussions.apple.com/thread.jspa?messageID=607556&
    <hr>
    Re the -39 error and the OS 9.2.2 download update, that error is most commonly caused by Stuffit Expander intruding where it should not. The download is in a .smi (self-mounting image) format, a format generated by Apple's Disk Copy. Stuffit Expander has ShrinkWrap technology built-in, which allows it to mount some kinds of disk images - but not .smi ones. Yet ShrinkWrap tries to - hence the error message.
    The solution - double-click Stuffit Expander, and open its Preferences (under the File menu). Select "Disk Images" from the list on the left, then turn off (uncheck) "Mount Disk Images". Quit Stuffit Expander.

  • How to transfer to computer from flash drive?

    I've installed the flash drive and it appears on Finder. I've been told that just need to select all and copy and paste. But I have no idea how to do that.Sorry for the novice question.

    It sounds like your flash drive is formatted as NTFS? (A Mac can not write to these).
    Plug it back in, highlight its desktop icon and press ⌘I.
    Then look where the resulting window says Format.
    Windows usually uses either FAT32, exFAT or NTFS. A Mac can only natively read and write the FAT variants.
    If that is the case copy everything from the drive to a temporary location on your Mac and reformat the flash drive, (if you have any individual files over 4GB in size you'll need exFAT). Once formatted check with a PC that it's all good before deleting your temporary files.

  • Strange USB Flash Drive Behaviour on Satellite A100-626

    Hello,
    I've cleaned install Windows Vista Business Edition on my Satellite A100-626 (PSAA9) following the instructions provided in the Drivers webpage.
    So far everything works as expected, except a small (or not) issue.
    When I ask Vista to "Safely Remove Hardware" my USB Flash Drive, a Popup appears telling me to remove it. So far, so good :D
    The only thing is that the flash drive doesn't power down as one could expect and and yellow question mark appears in device manager.
    Opening the question mark one can read the following:
    "Windows cannot use this hardware device because it has been prepared for safe removal, but it has not been removed from the computer. (Code 47) To fix this problem, unplug this device from your computer and plug it again."
    Following the above instruction the light go out, lol...
    Has anyone else encountered this strange behavior? If so, any solution?
    Tried a couple of USB flashes that work fine under XP and they both do the same.
    Thank You, Nuno!

    Hi
    Found something interesting on the Microsoft website:
    To fix this problem, unplug this device from the computer and then plug it in again.
    The device has been prepared for ejection.
    This error code occurs only if the user used the Safe Removal application to prepare the device for removal, or pressed a physical eject button. Restarting the computer brings the device online if the user does not want to eject from the dock.
    Unplug the device, and then plug it in again. Alternately, restart the computer to make the device available.
