Flash drive no longer mounts

As of last night, it always did, but today, I see nothing on the desktop or finder sidebar to indicate the flash drive's mounted. My MBP mounts other flash drives thru the same usb port and mp3 players, just not this one anymore. And I see it on our windows computer. Whasup widat?

Ick. I had that happen with a set of drives last week. In my case it turns out the adapter I was using was bad. In your case there's fewer options (since you say other drives work) - it's either a bad connection or a bad drive. As I said, Windows will detect drives if they are just plugged in, even if they aren't functional. Flash drives don't last forever... Do you have a USB extension cord to see if it's just a bad connection?
You can peruse the following but it doesn't sound like one of these issues.

  • Drives no longer mount - Only after restart do they mount

    Upgrade to from 10.4 to 10.5 and ran all updates...currently have 10.5.4. My external drives no longer mount when i plug them in via usb port. Worked perfectly before upgrade. Additionally my ipod wont mount either. They dont show up in disc utility either...However if i have these devices plugged in with the computer turned on (and they aren't mounting) and i restart my computer then when it boots up again they mount and function just fine. but if i unmount and turn them off and turn them back on...they dont mount.
    any suggestions?

    Hi grant862
    I seam to be having the same issue. I have a number of Flash cards and a flash card reader, well tow card readers actually. I cant get the cards to mount. I have tried swapping usb cables and card readers. I have tried both readers in all my USB ports (17" Mac Book - 10.5.4). The only way that I can get them to mount is if I plug the cards back into the cam,eras an connect them. I think there is a software glitch somewhere. I don't think its the usb ports as I have tried keyboards and mice connected via these ports with no issue. I don't expect an answer to this, but Grant - if you are still out there - I wanted you to know you weren't alone. I am going to try re-installing the 10.5.4 combi download and see what happens. Oh yes and 'repair permissions' (which I have already done once...) but am beginning to think that this is just a bit like saying a mantra as a way of calming me.

  • Daisy-Chained External Drive No Longer Mounting

    I have two external hard drives daisy-chained (firewire 800) to my iMac. The hard drive directly connected my iMac mounts fine. The daisy-chained hard drive no longer mounts, after mounting perfectly fine for a few months. I've tried restarting, etc with no success. Any help would be appreciated.

    No, it does not mount directly. I did however try using the other hard drive's power cord and it mounted without problem. But this doesn't fix the problem.. only one drive is mounting. At least it seems I have ruled out a more serious problem with the drive itself. I'm contacting Lacie to get a new power cord. Hopefully, with a new power cord, this will resolve the issue and it isn't some sort of daisy-chain issue.
    I think you have solved the problem by elimination.
    You can prove that it's the power cord by using the "bad" one on the working drive. If it stops working, it's guaranteed to be the power cord.
    I believe that there were some issues with some of the LaCie Power Supplies.

  • Connection to server fail/Flash drive will not mount

    I'm struggling with this issue and hope someone will have some insight these problems I'm having. I'm currently running 10.6.4 on my Mac and all of the sudden I'm unable to connect to my work's servers or mount a flash drive drive. The issue began after I corrected my disk permissions and restarted my computer. On the restart, I got a pop-up for each server I automatically connect to. The pop-up reads:
    +*Connection Failed*+
    +There was an error connecting to the server "SERVER NAME". Check the server name or IP address, and then try again.+
    +If you are unable to resolve the problem contact your system administrator.+
    At the same time, my flash drive, which has always worked, won't mount on my computer. But, here's the weird thing... I have two external drives connected to my Mac and they work perfectly. My only guess is that they're formated as Mac OS Extended (Journaled) and my flash drive is formated as MS-DOS(FAT).
    Any ideas as to why these issues are happening? Thanks

    Okay, this is just getting ridiculous. Turns out that my Mac will no longer mount a DVD. I'm working on a project in which I'm making a DVD with DVD Studio Pro and the disc burns just fine. However, when I insert to the disc to verify that it was burned correctly I cannot play the DVD.

  • BUG: Sandisk USB flash drive in "half-mounted" state after wake from sleep

    My Sandisk Cruzer Crossfire 4GB Flash Drive is left in a half-mounted state after wake from sleep. The Finder believes the drive is still mounted, the icon is on the Desktop. However opening a file on the drive, or trying to eject the drive, results in a long beach ball, followed by a message that I removed the drive without Ejecting it first. The same drive continues to work fine on my Tiger machine, and on PCs.
    Bug Report:
    Setup:
    Macbook 1st Gen (2.0 Ghz)
    Mac OS X Leopard 10.5 Clean Install
    Sandisk Cruzer Crossfire 4GB USB Flash Drive (in either port)
    Repro:
    Plug in the drive.
    Close the MacBook to put it to sleep
    Reopen the MacBook
    Result:
    The lights on the flash drive never light back up after wake from sleep. Navigating the drive, or trying to eject it results in a "you removed the device without ejecting it first" message.
    Expected:
    Drive should still be mounted and accessible after waking back up.

    It may be a design flaw in the device. Mac OS X does a lot more power management than most other OSes, including tearing devices down to little or no power during sleep. It is possible that the device simply misbehaves due to corrupted memory state or reports a substantially different GUID or something similarly bizarre upon wake. (Okay, that last one wouldn't technically be a power management issue....)
    If it doesn't have any problems except when sleeping the system, I would just make sure I unmounted it before putting the machine to sleep and wouldn't worry about it. Maybe check with Sandisk to see if they have a firmware updater for the device.

  • LaCie Hard Drive No Longer Mounts on iBook G4

    Hello,
    My LaCie 600 GB Hard drive will no longer mount onto my iBook G4. I had this problem about 6 months ago. It was solved by reformatting my whole computer through the installation disks that came with my computer. After I reformatted it, the hard drive was immediately recognized. I don't want to go that route again because I have a lot of programs on there that would take forever to reinstall. I have all of my important info backed up, just not the programs itself.
    I've tried running:
    Macaroni
    Utility Disk
    Data Rescue II
    And neither of these came up with any "diagnosis" on why my hard drive won't mount. I check my cables through plugging my hard drive in other computers, and it works fine. I think it has to do with my hardware on my iBook G4.
    When I plug it into my usb port, the blue light on my hard drive turns on, and I can hear the inside spinning. It just doesn't pop up onto my desktop. It doesn't show up in disk utility either.
    Any ideas on what I can do?
    -Kristen

    I would contact the folks at LaCie for their feedback.

  • Firewire 800 external drive no longer mounting

    My firewire 800 external hard drive is no longer mounting on my MBP. It powers up, spins, but has no reaction to being plugged into my computer. I've tried connecting it and the turning it on, and connecting it while it was already turned on. I've tried different cables and different types of adapter cables (fw800 to 400, fw800 to USB, etc.), but there is no communication between my drive and my Mac. Same goes if I connect it to my wife's Macbook, or my iMac at work.
    I recently had the logic board and left i/o board replaced on my MBP, I'm not sure if this is relevant since the drive has worked since the replacements and I get the same results on other Macs.
    What should I do next?

    who makes the drive set up?
    OWC for example has a history of bad power supplies that make the drive not accessible (drive spins up but never spins all the way up)

  • Extl Drive : No longer mounting

    I use my Lacie Firewire to backup my system. It is bootable and recently no longer mounts. It is daisy chain to another External Lacie Burner. I have taken the Drive
    to another Mac, to ensure that my firewire connections are OK. I have also removed all peripherals and done a PRAM. Repaired permissions and Diskwarrior.
    No joy. Any other suggestions please. Thanks

    Could try this, except without doing the hot plugging for Firewire (some debate about whether or not Firewire hot plugging, plugging while a device is on, is harmful or not. Probably not harmful, but just to play it safe.)This helped someone else recently.
    I solved such an issue with my firewire 800 drives via shutting down the Mac, pulling all cables (power, usb, audio, etc.), waiting for at least 15 seconds (I waited longer), and putting the power cable and keyboard/mouse cable back in.
    Then start the Mac, and when it finished loading the system try again mounting your drive by putting the cable in.
    It's an official procedure from Apple, but I can't seem to find the explanation on their side, the name of it escapes me.

  • Flash Drive Won't Mount Except At Startup

    Just bought a little 1Gb USB Flash drive which is USB 1.1 compatible. I want it for transferring files back and forth between my OS 10.4 G5 at home and the old blue and white G3 (OS 9.2.2) I have to use at work.
    Trouble is, the G3 won't mount the drive unless it's inserted before startup. Apple System Profiler knows it's there when I put it in one of the USB slots on the back of the computer or in the spare slot on the Macally keyboard, but in neither case does it mount. I've looked at the USB events log in System Profiler and it registers the device being inserted and its call on the USB Mass Storage driver like this:
    13436.785: [ 75579098]: Driver - Hub Driver - Device found, calling USBHubAddDevice. Port 3
    13437.266: [ 75580125]: Expert - LoadClassDriver: USBCompositeDevice1.5.6 - calling driver initialize routine... 0
    13437.267: [ 75580125]: Expert - LoadClassDriver: USBCompositeDevice1.5.6 - driver initialization completed 0
    13437.578: [-1744497139]: Expert - LoadInterfaceDriver: USBMassStorageDriver - calling driver initialize routine... 0
    13437.580: [-1744497139]: Expert - LoadInterfaceDriver: USBMassStorageDriver - driver initialization completed 0
    So there's nothing there that says "fail" there unless that's what the zero at the end of each line means.
    If I shut down the computer, insert the drive then start up, it shows up on the desktop no problem. It won't show up again if I trash and remove it though.
    However, a graphite G4 in my office, which also runs OS 9.2.2 and seems to have an identical system install, will mount the drive with no problem on any of its USB ports.
    Is this a case of the G3's USB ports being underpowered and there's no way round it, or is there a fix out there somewhere?
    G3 Blue & White   Mac OS 9.2.x  

    However, a graphite G4 in my office, which also runs OS 9.2.2 and seems to have an identical system install, will mount the drive with no problem on any of its USB ports.
    Try this: Copy all of the extensions on the G4 that have USB in their names into the Extensions folder on the G3, replacing the USB extensions that are there; then restart and test again. Some of them may be older or newer versions than the ones on the G3 now, and that can make a difference. Note that in OS 9.x, it isn't always the newer versions of the USB extensions that work better.
    Also see this user tip from Apple employee Joerg Weise. In it he lists 6 USB extensions (with version numbers) that can often resolve USB problems in OS 9, even under circumstances different from those described at the beginning of his comments.

  • USB flash drive won't mount

    I have a strange problem with a USB flash drive which refuses to mount on the desktop of my MDD FW800. It registers in System Profiler but not in Disk Utility. I can't get it to mount using Terminal either. The Terminal screen says it has mounted but it doesn't appear on the desktop and I can't access it. However, if I do a restart with the the drive plugged in, it does mount. If I eject it and then try to plug it in again, it won't mount! Very frustrating.
    It works fine on my Powerbook and my Digital Audio so it can't be the drive itself that's the problem. Not quite sure when this started but it may have been after I installed a PCI USB2.0 card (a Ratoc Rex-PCIU3). The card itself works fine with other USB products and I don't have any deep sleep problems with it either. I'm stumped.
    Any suggestions anyone?

    Hello rickame
    Click on the desktop then go up to the menu bar and select Finder / Finder Preferences / General and make sure the box's are checked for Hard disk, External disks, etc.. then reconnect the drive. If you still don't see it on the desktop it may have been improperly disconnected from the iMac while mounted, look to see if it show's up in Disk Utilities and the System Profiler on the USB bus. If you are plugging it into the keyboard, try one of the USB ports on the back of the iMac or a powered hub. There also could be a conflict with other USB devices, try ejecting and disconnect things like an iPod, a printer/scanner or camera, then restarting the iMac and connect only the Flash drive.

  • Using flash drives for long-term backups

    I use a USB flash drive to backup my mom's iPhoto Library. I've heard, however, that flash drives are not reliable for long-term backups. Is this true? If so, what is the best alternative?

  • Installed itunes - usb flash drive no longer recognized

    hi,
    I installed itunes, loaded up the ipod with music, and now my computer will no longer read the files off my usb flash drive. the computer sees the "mass storage device" when I plug my drive in, but the volume/files are not coming up.
    any suggestions?
    thank you!

    Are you sure the files are still on your Flash drive.? Can you locate them in a folder on you flash drive just by going to the iTunes\iTunes Music folder and viewing the array of folders? If they are there, go back to the iTunes icon on the desktop, bring up the list of tunes, highlight them all, delete them, and go back to the Flash drive, highlight all the folders, drag them over to your blank iTunes screen and drop them. You won't get any indication anything is happening right away but they are reloading. For some reason iTunes cannot update itself with the correct pathways.
    Hope this helps, Dave.

  • Usb flash drive won't mount in disc utility

    running mountain lion on new imac .... usb flash drive was working, the next hour inserted it again and it doesn't show up in "devices".  Opened disc utility - it shows up there but won't mount and all the "verify disc" and repair disc" functions are greyed.
    Same result when I insert it into my macbook.

    Did you put it in another computer and save data to it since it last worked? did you properly eject the disk?
    sounds like you need to reformat the flash drive
    If you need to save the data , plug it in to a pc and see if you can copy to hd.
    Then take to your Mac and format it in disk utility. I recommend using windows format.
    Then plug in to your PCM and get the files.
    Then.. Eject the USB disk, don't just pull it out. Take to your Mac and it should mount

  • Flash Drive No Longer Recognized

    I purchased a new PNY Turbo 3.0 128 GB Flash Drive, formatted it as Mac OSX Journaled, transferred files to it, encrypted it, used it for about 30 minutes on my iMac, then it disappeared while navigating in Finder.
    The flash drive does not show in Finder, Disk Utilities, or System Information.  Yes, show external drives is checked in Finder Preferences.
    The USB is recognized in an older Macbook using a much older OS, although I can't view the contents and a message on the Macbook says that I need to put the drive into a device with an updated Mac OS.
    No other user accounts on my iMac can view the flash drive.
    So far I have done numerous restarts, shutdowns, and remounts, reinstalled Mavericks (again), repaired disk permissions, etc. 
    This is the second issue I've had with an Apple formatted and encryped flash drive disappearing.  I've put an entire Sunday afternoon reading through threads and troublshooting this, and looks like some people just accept it as another thing that doesn't work on their Mac or go try different brands of flash drives until one works.
    Suggestions or recommendations anyone?  I would like to keep this flash drive (it does have the Mac symbol on the packaging) if possible.

    Did you ever get a satisfactory response to this?
    I too have just encountered this issue.  I have a PNY USB 3.0 128MB flash drive.  I used it successfully for several months.
    Today, connecting it to a brand new Mac Mini, 10.10, it is not recognized.  It's not just that it isn't recognized... It's not even showing up in Disk Utility.  The only indication I have that the system has detected it is this log message:
    2014-10-26 12:20:55.000 PM kernel[0]: USBMSC Identifier (non-unique): 09031000003796153712 0x154b 0xfa05 0x1075, 2
    Also, it shows up in System Information, in the USB Device Tree, but nowhere else.
    I then tried it in my Retina MB Pro (2.3GHz i7) running 10.9.5, where I had always successfully used it, with the exact same results.
    It appears that the OS is failing to load the driver, or perhaps something in the USB negotiation is failing.
    I tried it on a couple of Macs, running 10.9.5, both USB2.0 and USB3.0, with no luck.  My old Snow Leopard 2005 iMac recognized it, but the filesystem was too new for it to read it. (It is an encrypted USB volume).  I was, however, able to copy the raw disk image, even though that mac couldn't read it.  I am hoping to access the files that way.
    Now... I just put the USB Key into another of my Macbook Pros, an old 2.33GHz Core2Duo running 10.7.5, and this machine was able to access the encrypted partition with no problems at all.
    So, I conclude that this is some problem related to 10.9.x, since both USB2.0 and USB3.0 Mac's running 10.9 were unable to recognize the disk, yet a 10.7.5 machine with USB2.0 reads this disk fine.
    I'm hoping to get a suggestion from someone on how to best go about finding the root cause of this issue...
    Thanks,
    Pat
