Encrypted USB No Longer Recognized by iMac

I have a journaled and encryped USB that has worked fine in the past but I have rendered it unrecognizable trying to fix another issue.
Many .pdf files on this USB were not being recognized by Spotlight, so I followed the steps to reindex the drive found here http://support.apple.com/kb/ht2409. 
I made it to step 4 and could no longer get the drive to show up in finder.
I mounted and remounted the USB drive a number of times, shut down and restarted the computer, and followed the directions here http://support.apple.com/kb/PH3888 without success.  Now the drive won't even show up under in Utilities - USB.
Any assistance would be greatly appreciated.

After re-installing Mavericks it showed up if I clicked on "Deviced" - "My iMac."  It no longer shows under "Devices" but at least it is recognized again.

  • 2 TB External Drive no Longer Recognized by iMac 27"

    I have a 2 TB external HD (actually two 1 TB drives housed together in a OQC Mercury Elite Case) that has been working flawlessly for about 10 months as my Time Machine backup to the iMac 27". I have it hooked via FW800.
    Yesterday I noticed that TM backup failed and when playing around, I also noticed that the drive was no longer recognized. I check System Profiler and the drive was not seen. I did a PRAM reset (as this usually fixed the FW800 issues), but still no drive.
    Thinking I had a faulty FW800 port on the iMac, I switched the connection to USB 2. I see the Drive listed in the USB Device Tree in System Profiler, but still nothing on Finder.
    I opened Disk Utliltiy and I see a listing for a "2 TB External Raid Media" and then as a indent is says "Disk 3s3", but this is grayed out and you can not click on it to, say, repair permissions.
    I installed an update late Friday night and I have no idea if this is the reason, but I am curious what the next step might be. I am using 10.6.4.

    James,
    There are some basics you can do to do trouble shoot the FW800 problem. First is doing a SMC reset, follow the instructions for Intel based iMacs. This letter covers multiple models of Macs and you need to follow the correct procedure.
    The next item to try would be resetting the PRAM.
    Finally The X Lab has written a good article on troubleshooting Firewire devices. You can locate that article here.
    Hope this helps out some.
    Regards,
    Roger

  • Since installing Leopard, my iPhone is no longer recognized by iMac

    Since installing Leopard, my iPhone is no longer recognized by iTunes and cannot synch. Could you let me know how I can get iTunes to recognize my iPhone again. It is odd since i plug the iPhone into the iMac and it is no longer recognized in iTunes and my address book and calendar. It worked fine before installing Leopard. You assistance is greatly appreciated.

  • IMac USB no longer recognizing 3rd party phones (BlackBerry, Android, or Symbian).

    Hey everyone, this is my first post to this community support group.
    Last week, using my iMac, I attempted to install the Ubuntu OS onto my Nexus 7. 
    I followed some online guides on how to do so, and realized that I was not up to the task.  The process involved various things, although the one I suspect created my current problem was inputing Terminal commands (unfortunately, I can not recall the commands I entered).
    Not only was I unable to install the Ubuntu OS on my Nexus 7, but now my iMac does not recognize any 3rd party phones (Android, BlackBerry and Symbinan) that are plugged into the USB ports.  Prior to this Ubuntu attempt, my iMac recognized all phones plugged into it's USB ports.
    A few things:
    1) The USB Device Tree in System Information lists several connected USB devices (iPhone, Printer, External Drives, Etc), but will not display 3rd party phones.
    2) The Disk Utility does recognize any phones as hard drives, when they are plugged in via usb.
    3) I've tried using the phones' interfaces to switch them from USB mass storage, to camera, to charge settings when plugged into the iMac with no effect.
    4) I've tried plugging the 3rd party phones in different USB ports with no results either.
    Thank you for any help and guidance you guys might offer!

    Try doing both a iMac SMC and PRAM reset, it may take several attemps for it to work.

  • IPAD usb no longer recognized by itunes

    Why does the windows 7 PC not recognize USB from the iPAD in iTunes?

    Folks,
    I had this problem with my PC (windows 7, 64-bit) and my iPad. After messing with it for a long time, I finally found the answer (bad USB driver). The following two step process should help resolve these kinds of problems more quickly.
    The first step is to verify that the iPad (or iPhone) is really connected to your computer. This can be (really) checked using a program called USBDeview. You can get this (very small) program from http://download.cnet.com/USBDeview/3000-2094_4-10614190.html or http://www.nirsoft.net/utils/usb_devices_view.html. Don't worry, it's not Spyware or Malware.
    Just run the program and sort on the 'Connected' column. If your iPad or iPhone doesn't show up as Yes (under 'Connected') then your iDevice is not properly connected to your computer. Could be a cable problem. Could be an iDevice problem. Could be a USB hub problem. Note that your iDevice might be listed as what it is (iPad or iPhone) or it might be listed as 'Apple Mobile Device USB Driver' in the 'Description' column.
    Apple has a number of ideas to resolve this sort of basic connectivity issue, including switching USB ports, resetting your iDevice, rebooting your iDevice, rebooting your computer, etc. You will need to try them until your iDevice shows up in USBDeview as 'Yes' under Connected.
    If you iDevice shows up as 'Yes' under connected, it should also be visible in the Device Manager (found in the Windows 7 Control Panel under Hardware and Sound). You might find it under Portable Devices or it might be under Universal Serial Bus controllers.
    The iDevice may or may not show up in the Windows Explorer. On some machines it does, on others it does not. Why is not clear.
    If the Idevice is properly known to Windows and iTunes can't see it, then any number of other things could be wrong. Apple has a list. See the very useful page over at http://support.apple.com/kb/TS1538. Testing shows that the Apple Mobile Device service must be running. Check this using Task Manager (started by right clicking the taskbar). Note that the iPod service and the iphlpsvc service must also be running. These services have different names under the Processes table versus the Services tab of Task Manager.
    AppleMobileDeviceService.exe - Apple Mobile Device
    iPodService.exe                      - iPod Service
    ItunesHelper.exe                     - iphlpsvc
    Step 4 of http://support.apple.com/kb/TS1538 checks if the Apple Mobile Device USB is installed. This is essential and a common source of problems. In at least some cases, Windows will install the 'MTP USB' driver. Indeed, Windows will reinstall this driver if you uninstall it. The MTP USB driver is essentially a Windows bug (possibly caused by Microsoft). You must replace the MTP USB driver with the Apple Mobile Device USB Driver. Step 4 explains how to do this. Note that you must use the 'Have Disk' approach. Otherwise, Windows will just reinstall the invalid MTP driver.
    The Apple doc indicates that you can find the correct driver at C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\Drivers. Perhaps this is correct on some systems. You may find the correct driver in C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers.
    iTunes could make this a lot easier by checking if the iDevice is known to Windows (what USBDevier does) and if the Apple Mobile Device USB driver is properly installed for the iDevice. Sadly it doesn't perform either check. Note that iTunes does if some of the related services (see above) are actually running.

  • Vixia HF10 no longer recognized by iMac

    I've had my Canon HF10 for about a year now and I used to be able to connect it via usb and iMovie would automatically open and I could import my HD movies. I haven't touched the HF10 since at least Thanksgiving '08 and decided to load the movies into iMovie and was surprised to find that it wasn't even showing up as being connected. I've been trying for a couple of days now and have gotten the HF10 to mount a few times but I just got the beachball of death on iMovie. I also have Toast 10 and it's not recognized by it either. The only difference I can think of is that I now am using iMovie '09 instead of '08 but from other posts it doesn't look like that's the problem. Any ideas on what could be wrong? Any help would be greatly appreciated. Thanks, David

    If you suspect corrupted software then the answer would be to re-install.
    However, try this first.
    Update your software Apple > Software Update.
    Open Applications > Utilities > Disc Utility.
    In disc utility, click on your mac HD in the left pane then in the main pane, click 'Repair File Permissions'.
    That takes a few minutes, then shut down and re-boot your mac.
    See if that fixes your problem otherwise a re-install of iMovie via the iLife disc or you software install disc.
    Make sure that if you install, do a software update after.
    Regards,
    Z

  • Time Capsule is no longer recognized by iMac

    I have a Time Capsule (model# A1409) that is not recognized by my iMac.  I was using the time capsule with an older iMac which I gave to my son after purchasing a new iMac.  I also purchased a new router Airport Expreme Base Station (model# 1408)  and have two Airport Express Base Stations that serve as signal extenders (I had one Express Base Station but the signal was still weak where my son's computer is located, and so I purchased another one).  I want to use the Time Capsule as an external hard drive, but the Airport Utility on my new computer does not recognize it, even after performing a reset and connecting it directly to my iMac with an ethernet cable.  The Airport Utility only recognizes the Airport Extreme Base Station and the two Airport Express Base Stations.  I have scheduled a genius bar appointment but also wanted to try to post my problem in the Apple Support Community to see what responses I might get. 
    Thanks,

  • Bluetooth keyboard no longer recognized by iMac

    My Bluetooth keyboard has suddenly stopped working - it doesn't show up in BT preferences, nor in the dropdown BT menu. When I attempt to add a new BT device, the keyboard is recognised by its name (the one it has always had), but attempts to pair it always fail.
    I have reset the SMC to no effect.
    The green light doesn't flash while I'm attempting the pairing - I don't know whether it should or not.
    BT seems flaky - sometimes it offers me a code for the pairing, but usually not. I've tried to pair it about thirty times in all.
    I don't understand why the keyboard doesn't show up in the BT preferences, since its name is recognised when I attempt to pair it. Since its name doesn't show up in BT preferences, I obviously can't delete it from there and start afresh.
    All help gratefully received.

    Update: I have solved the problem as follows.
    1 I changed the name of the BT keyboard - I don't know if this relevant or not.
    2 I took the keyboard out of range of my iMac by taking in down into my basement - when I did so and switched it on down there, the green light started to flash, indicating that it was now in pairing mode. Previously, when my keyboard was close to my iMac, the green light had not flashed.
    3 I came back upstairs to my iMac, and BT setup recognised the keyboard under its new name.
    4 BT setup then gave me the 8-digit pass code, which I entered, and the pairing was completed successfully.
    So it seems that re-enabling the pairing mode can be achieved by taking the BT device out of range of the home computer, and once the BT device has established its pairing mode/status, the process works as it should. If this is correct, it may be of help to others with a similar problem.

  • Time Capsule USB no longer recognized

    So, about 3 months ago I bought a USB drive/flash drive/whatever big enough to use as my Time Capsule backup disk. I ran TC and everything backed up perfectly, even did two maintenance backups at 2 week intervals. I inserted my drive the other night to update my backup files and the USB drive won't show up in Finder. I tried it on my sister's MacBook too, and it didn't show up on hers either. Anyone have any advice other than "go buy another drive"? I'm on the "grad school budget" and can't really spring for another one.

  • My old Intel-Based iMac is no longer recognizing USB wired input devices; it only recognizes Bluetooth.  What happened?

    My friend's old Intel-Based iMac is no longer recognizing USB-wired input devices (Kensington TrackBall, Logitech Mouse) plugged into any USB slot at the back of the computer.
    They were working before and for many years.
    All of a sudden, A pop up window came up. IT said no Bluetooth mice could be found.  We don't know what set off that window to pop up and look for a WL mouse. It never has before in the 5 or more years my friend has been using this computer.
    I supplied a wireless Apple mouse and his is back running again.
    But want to know why his USB-input devices (Except his keyboard) are not being recognized. He would prefer to use his  Trackpad (Wired), but can't find anything in SYstem PReferences to allow that.  The computer only seems to want a Bluetooth input device.
    Anyone have an idea what happened and if this can be reversed?
    I think he is still running Mac OS X 10.5.8.

    Hi Carol, lets try this...
    reset FW bus, same goes for USB reset...
    Reset the Firewire bus
    If your Firewire or USB isn't recognizing any device.  A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:
    1. Shut the machine down.
    2. UNPLUG the power lead to the computer and any firewire/USB drive/devices.
    3. leave it for 10 minutes.
    4. Connect back up and reboot.

  • My first generation iPad no longer recognized in iTunes, neither via usb nor wi-fi. Did all the steps  recommended in Apple iPad support. Now what?

    My first generation iPad is no longer recognized in iTunes. It just doesn't show up neither via USB nor via wi-fi.
    I've checked the usb connection and cable and its OK.
    I checked that iTunes is up to date on my Mac.
    I reinstalled iTunes on my Mac. 
    I restarted my Mac,
    I've restarted my iPad.
    The iPad has IOS 4.3.1 (8G4) installed. And without the iPad being recognized in iTunes  I can not update the IOS nor apps, nor remove unneeded photos. The iPad is completely filled up, no memory left to allow even updates via cellular or via wi-fi.
    Trying to gain access to update the IOS and to update APPS and to remove the pics I already have backed up and do not need on this iPad locally.
    PS: I even tried to connect the iPad to a different Mac and it was not seen in that iTunes either.
    So, what can I do now?
    Any suggestions besides using it as a paper weight?
    Thanks

  • I upgraded Windows 7 to Windows 8 with iTunes installed. Now my iPhone 4S is no longer recognized in iTunes. Connecting with USB sends me directly to the MS app that downloads pictures from the iPhone. Suggest this is a question of missing Apple driver.

    I upgraded Windows 7 to Windows 8 with iTunes installed. Now my iPhone 4S is no longer recognized in iTunes. Connecting the iPhone with USB sends me directly to the MS app that downloads pictures from the iPhone. Suggest this is a question of missing Apple driver for Windows 8, iTunes and iPhone. MS does not care! This seems to be a general problem with Windows 8 that a number of drivers that used to work with Windows 7 now do not work, ie. iPhone to iTunes, HTC to HTCSync, Samsung to Kies etc. I need this connection to work in order to syncronize with Outlook and my iTunes library.

  • USB devices all of a sudden no longer recognized in windows 7

    Hi,
    I am using a HP Pavilion Simline s5550nl edition with windows 7 home premium (64-bit) since 1.5 years. Never had any problems until 3 days ago. Since 3 days suddenly some new devices, already plugged-in devices and previously used devices are no longer recognized (USB-device not recognized-error after plug-in).
    I used an USB-mouse, USB-keyboard, Smartcard-reader, Sony Story 1.5TB External HDD, USB WebCam. They al worked fine.
    3 Days ago I bought a WD Elements 2 TB External HDD. After plugging in, it was not recognized at first. Replugging it in it was recognized, but trying to open the drive in Explorer, it gave a not-formatted-error (while the disk should have been pre-formatted for Windows 7). However, i tried to format the disk, but it could not reach it any more. After rebooting the system the WD elements HDD gave the USB-device-not-recognized-error, using all other USB-ports didn't change that. In fact my Sony External HDD was no longer reachable either. Unplugging and replugging it in gave the same USB-device-not-recognized-error. Trying previously flawless working USB-devices all gave the same USB-device-not-recognized-errors (USB-flash disk 4GB, External HDD 2.5inch 160GB, USB-/card reader HUB, iPhone).
    I then tried to connect my Sony and WD external HDD on my other computer with windows XP SP3. They were recognized within seconds and working fine (also the WD elements External HDD indeed turned out to be pre-formatted).
    Strangely enough my USB-mouse, USB-keyboard and smartcard-reader kept being recognized at plug-in. Furthermore, my printers (connected over LAN) and NAS (connected over LAN) were usable without any problem. I did not encounter any other problems in functionality of windows. I then thought it might be a corrupted general USB-driver for mass-storage or something, so I started to google this problem. Things I have done so far (before each step I unplugged all USB-devices, rebooted and reconnected the devices):
    - Turning computer off, unplug power-cable for 2 minutes, reboot.
    - Updating BIOS to version 6.04 (was running version 6.02).
    - Uninstalling all USB-devices/mainhubs etc in devicemanagement, automatic reinstallation at restart.
    - Try installing newer USB-drivers for mainhubs, messages the installed drivers are already the latest.
    - Uninstalling all 'hidden' USB-devices.
    - Trying to go back to configuration of 1 day ago (maximum i could go back), resulted in an error that  the file might be corrupted.
    - Turning computer off, unplug power-cable overnight, reboot.
    - Running HP-systemdiagnostics: all passed.
    - Running Norman anti-virus scan (latest update): no infection.
    - Again uninstalling all USB-devices/mainhubs etc, automatic reinstallation at restart.
    I also noticed that during the night before this malfunction appeared (so actually several hours), on january 20th, an automated microsoft critical update was installed (some anti-spyware definition update). I am now thinking it might still be a driver-problem of some sort of general USB-mass storage driver or due to this microsoft update or maybe some clever virus.
    I no ordered a Recovery disk (never had to use one, so did not jet own one), to recover windows and if that doesn't help reinstall it. However I hope that anyone can bring up a solution that I am overlooking?
    D. Berks

    OK, meanwhile I found that only uninstalling the USB2-driver enables the USB-ports again. Uninstalling it makes al devices recognizable, whil reintsalling it immediately makes all USB-devices unrecognizable.
    I tried updating the driver to the latest version, deleting it (after reboot an automated reinstall is triggered), but nothing helps. As if soething that stays in the system makes USB2 to corrupt USB-channeling or something.
    I strongly believe that it has something to do with the windows-update, but I can nowhere as a question about it to microsoft (will cost 70 euro's!).
    Does anybody knows what this could be? Or better: knows of a solution?
    Tanks,

  • USB Device no longer recognized (Ratoc U2SCXU SCSI Converter)

    I'm having problems with a device that used to work fine in an older MacOS (10.5, Leopard) but no longer being recognized in Lion. The Ratoc Systems International SCSI COnverter model U2SCXU is no longer visible in System Information, their Utility, nor the scanning software (VueScan). This set up used to work seamlessly in previous OS's.
    The Ratoc device is being powered through the SCSI connection and lights the power light no problem. No matter wherther through a hub or direct, the USB is no recognized nor is the software. I tried to email the manufacturer but in the meantime thought to post this as a question while waiting... Does anyone have a similar problem?
    Using with a Polaroid SprintScan4000 negative scanner. This device and the converter were all running and playing happily in OS X 10.5. There seems to be nothing I can do to make the device appear in the window, nor be recognized in software. Also tried with laptop running the same OS. I believe this is a software issue with the OS. There is a firmware update that might be able to be applied via the Utility software (U2SCXU_50) from Ratoc website, except that the Utility doesn't see this unit either.

    Make sure it's the right series usb 3 driver, series 7 or series 8.  Series 7 drivers are version 1.x and series 8 are version 2.x.  They use the same device id's.
