My USB flash drive, which has worked before, isn't recognized by my Mac anymore. How can I recover data on it?

Help, please?

I've found multiple data recovery programs, but Iäm wondering if they might just do some damage and whether they're reliable?

  • If i use a usb flash drive which is both os and windows compatible can i transfer files from my mac to a windows pc using the same usb flash drive?

    if i use a usb flash drive which is mac os and windows compatible can i use it to copy files from the mac to a windows machine. i have to do some training abroad and wnat to take the files on a usb from the mac but they will only have a windows operating system available to me.

    Generally, it's not the flash drive that makes it compatible, but the formatting used on it.  In Disk Utility on a Mac, the format is called MS-DOS (FAT).  In Windows, I believe it is called FAT32.
    A USB flash drive formatted that way should be readable and writable on both Mac OS X and Windows.  But you may want to try a "trial run" before relying on it for the trip.

  • HT4098 I have a subscription to The Telegraph which I purchased before changing my email and apple ID.  How can I get iTunes to transfer this purchase and put it under my new apple ID?

    have a subscription to The Telegraph which I purchased before changing my email and apple ID.  How can I get iTunes to change it to current ID

    Did you create a NEW Apple ID or did you change the email address for your OLD Apple ID? This will affect how you update apps in the future.
    Anyway, go to Settings/iTunes&App Stores, log out, then log in with the new ID.

    How Restore Deleted or Missing OS X Components
    A few of the basic OS X installed applications can be restored from the Optional Installs installer located in the Optional installs folder on your Installer DVD.  However, if what you need is not there then follow the instructions below.
    How to Use Pacifist to Restore Deleted or Missing OS X Components
    Insert the OS X Installer DVD into the optical drive.  Use a simple utility like TinkerTool to toggle invisibility so you can see invisible items.  Alternatively, open the Terminal application in your Utilities folder and at the prompt enter the following:
    defaults write com.apple.finder AppleShowAllFiles Yes
    Press RETURN.
    To turn off the display of invisible files repeat the above command substituting No for Yes.
    The install packages are located in the /System/Installation/ folder on the DVD.
    Download the shareware utility Pacifist. Use it to extract a fresh copy of the missing item(s) from the file archives on your OS X installation DVD. The file archives are in the /System/Installations/ folder (use Go to Folder option in the Go menu of the Finder.)
    Here are Four Basic ways to use Pacifist (courtesy of George Orville.)
    Drag a .pkg icon onto the Pacifist window .....proceed to step 7.
    Click on “Open Package ....” and navigate to package desired and click “Open” in the open/save window.....proceed to step 7.
    Insert Mac OS X installer CD and when it mounts, navigate to .... Menu->Go->Go to Folder. In the path field enter or paste ....
    /Volumes/disc name/System/Installation/Packages (where disc name is the name of the CD/DVD that you inserted.)
    Click on the  "Go" button ..... • Drag a .pkg to Pacifist..... proceed to step 7.
    The package you'll need will have to be discovered by trial and error, but for most applications you should start with the Essentials.pkg and/or Additional Essentials.pkg.
    D. Insert your Mac OS X install disk 1 .... and open Pacifist.
    1.          In Pacifist, select "Open Mac OS X Install Packages" ... dialog may appear asking for disk 2, then disk 3 and finally disk 1 again.... {if DVD is not used)...If “Stop Loading” is selected...the procedure will stop!!!
    2a. When loading is complete, a new window appears, click the triangle to display contents of each package...Select item and proceed to step 7.
    2b.          or click the “Find” icon in the Pacifist window and type the name of the software you need.
    3.          In the list that comes back, click the top most entry for the item that you want. ..... that is the one for the English language.
    4.          On the top of the Pacifist window, click “verify” .... you will probably be prompted for your password.
    5.          Enter checks for.... “verify permissions” and “verify file contents.” and click “verify” ....enter password when prompted.... you will get back output which may look like this:
              20 files were scanned. 20 of 20 files were present on the hard disk. 0 of 20 files had file permissions that did not match those specified in the package. 0 of 20 files had checksums that did not match those specified in the package.
    6.          Click “close”. Go to step 7.
    Extract or Install........
    7.          In the Toolbar (upper left), you now have the option to extract or install. Click a file in the lower list and those two icons will be enabled.
    8.          If “Extract to...” is selected.... navigate to the location where the file will be placed, select “choose”, select “extract” in new dialog that appears,authenicate , if prompted, click “OK”.
    9.          In the next dialog, click “Extract”.
    10.          If “Install” is selected... dialog will appear with the location/path of the installed software. Click “Install”
    11.          Type in your password, click “OK”
    Pacifist will begin to extract files.
    12.          In steps 8/10ß.... you also have the choice to “cancel”
    Notes:          Pacifist may find that a file it is installing already exists on the hard disk. Pacifist will present you with an alert panel....
    Stop
    Leave original alone
    Update .....
    Default selection
    Replace .... (Replace option should only be used on full install packages)

  • My daughter has somehow figured out how to register for her own Apple ID but is very underage. She is not giving me the correct info for me to get into her email. She has downloaded some apps that I would not allow. How can I recover her Apple ID info?

    My daughter has somehow figured out how to register for her own Apple ID but she is very underage. She is not giving me the correct info for me to get into her email. She has downloaded some apps that I would not allow. How can I recover her Apple ID info?

    No it's not stealing. They have an allowance that you can share with so many computers/devices. You'll have to authorize her computer to play/use anything bought on your acct. You can do this under the Store menu at top when iTunes is open on her computer.
    As far as getting it all on her computer....I think but I am not sure (because I don't use the feature) but I think if you turn on Home Sharing in iTunes it may copy the music to her computer. I don't know maybe it just streams it. If nothing else you can sign into your acct on her computer and download it all to her computer from the cloud. Not sure exactly how to go about that, I haven't had to do that yet. I wonder if once you authorize her computer and then set it up for automatic downloads (under Edit>Preferences>Store) if everything would download. Sorry I'm not much help on that.

  • Usb flash drive v240w stopped working

    Hi....... i have a hp usb flash drive v240w that had stopped working..????
    tell me what i can do to make it work again... or what i have to do for replacing it..

    If it was mounted to a system and not ejected correctly you might have messed up the boot record and mount point, if you can see it Disk Utility then the mount point of that drive is bad, you have to reformat it.
    Mr H might have ejected it incorrectly (without doing the command E thing) but really I doubt it.
    Not quite sure what you are saying here: since we DO see it in DU (where it says not mounted) then there is no way even to look at what is on the drive (the number of files and used space shows up in DU as well) and all I can do is reformat it? 
    I attached a good, working flash drive and it too shows up in DU, but it indicates where it is mounted (volumes/... if I recall) so I don't get what you say above where I underlined it.
    Originally drive was formatted as MBR I suspect, being Sandisk.
    I've never bothered to reformat the flash drives from their original formatting in the past - I use several and never have I had this problem.
    As long as I have to now, what format do you suggest?
    Thanks,
    Mrs H

  • While updating software of Ipad, it stop working and only shows the Apple on screen. How can I recover?

    While I was updating the software of my IPad, it stopped working and only shows the apple logo. How can I recover my IPad?

    Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds, after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • USB Flash drive will only work on the Mac

    I have a Toshiba 32 GB flash drive and tried to copy music to it. The music plays thru my Mac but when I put the drive into my Subaru or Sony amplifier I get the message that the drive is unrecognized. I tried to partition it with the same results.  Is there a certain partition to use? I have tried all that were offered in Disc Utility.

    From a subaru forum "Zero problems using 16gb SanDisk Cruzer USB 2.0 Flash drives in whatever head unit is in a non-nav"
    It may depends what head unit you have, same for the sony amplifier, many units cannot read over 8 or 16gb, try a different / smaller usb and give it a go.  Also maybe try formatting your stick at work or a friends computer to fat16

  • I have a 1st generaltion apple tv which was recently changed from HDMI to component cables to connect to TV; now it will not remember my server password or my apple ID information which has to be re-entered everytime I use apple tv; how can I fix this

    I have a first generation apple TV. recently I have rto change from HDMI input to my TV to a component imput. Now my apple tv will not rememebr my sertver password or apple ID which I have to re-enter everytime I use Apple tv which is annoying; how can I fix this?

    Changing the video connection has nothing to do with the passwords.
    Are you certain it is a 1st Gen ATV?

  • Importing bookmarks in FF32 does not work. I have tried swapping places which has worked before, I have tried import in the bookmarks menu.

    This is a windows 8 computer that was RESET yesterday that I am attempting to set up again.
    I have copies of the bookmarks on another drive (and actually on another windows 8 computer running FF27) - I can not move the bookmarks onto this reset computer.
    I have not attempted to move the whole profile yet just places and also tried export /import bookmarks.
    I have just reinstalled FF32 and have the same problem. Yesterday I was successful in moving "places" onto the windows 8 computer with FF27.

    somehow it is now working - it wasn't a few minutes ago but I do have bookmarks now and can add them
    I tried lots of the suggestions - "You can try to delete the prefs.js file and the compatibility.ini file to force Firefox to reinitialize the profile." - tried it but it alone wasn't enough
    I also installed Java during this process - it was probably needed and might be automatic to a techie but I am a mathematician not a computer person. I know I had installed java in the last few days but it wasn't visible in a search for the word java so I downloaded it again.
    I took bookmarks back up file, places.sqlite, and bookmarks off the working Win 8 machine and tried to move them into the right spots in the folders - didn't work at first
    I discovered the date on the working Win 8 machine was a day off and so when I opened a backup bookmark that was old enough with all the other changes I had made it finally worked.
    I see now where the bookmarking star has moved - I liked the star in the location bar. I normally just use history. I also do not like the tabs on the top and other toolbars hidden away and change some of those on install. I will change these two Win 8 to my liking over this week but all of those changes were not urgent.
    I have relinquished control of that Reset PC back to its "owner" until the next disaster. I know I have one program left to install (no rush I was told) and a handful of files to straighten out still but this last thing is status quo around here.
    Thank you for all the ideas.
    There is also System # 4 - Windows 7 with FF31 which is my main computer - System #2 exists as it was bought for me but I have not used it. I hate Windows 8 and hate the idea of moving all my files onto it. But there are enough problems on this CPU that if I gave it away as a hand me down I would spend too much time trying to fix it for my spouse so they got a brand new PC instead to replace XP. When I gave them the XP they got it "clean" with a new install of XP on a just cleaned HD.

  • MS Word crashed and now my USB/flash drive doesn't work.

    My MS Word crashed and when it recovered I got an alert saying my USB was not ejected properly (even though I didn't eject or remove it). I then removed it and put it back in and now my MacBook Air won't read it at all, and when I try it on a Windows laptop it says the drive is empty.
    Please help! It has all my uni files on it!
    Thanks so much.

    Try plugging it into your MacBook and then repairing the disk permissions using Disk Utility.
    Repairing a disk's permissions using Disk Utility.
    Note: This should not delete any information or files from the disk.
    Repairing a disk's permissions can help solve various file-related issues.
    To begin, make sure your external disk that you are repairing is connected to the computer. If you are repairing an internal disk, skip this step.
    After the drive is connected, launch the Disk Utility application in any of the following ways:
    Type the first few letters of its name into Spotlight. Select it from the results.
    Go Finder > Applications > Utilities > Disk Utility
    Go Launchpad > Utilities > Disk Utility
    Once you are in the Disk Utility app, select the external drive from the sidebar on the left.
    Then, choose the Repair Disk Permissions button on the right.
    If this does not solve your issues, you may have no choice but to reformat the drive using Disk Utility.

  • LG USB Flash Drive Problem

    I have an LG 1GB USB Flash Drive, which has worked flawlessly for the last year or so. All of a sudden, just recently, it always takes two tries for it to mount. In other words, when it's inserted the first time it doesn't mount, but remove it and insert it again, and it mounts! I've reformatted it (Mac OS Extended), but it didn't help. I've also tried it on two other Macs, and it's the same thing. Any suggestions?

    Hi anybody,
    I have a similar problem with a flash drive. I was just using it on a PC, properly disconnected it from there and then plugged it into a USB hub I have on my Mac. Now it's dead. No light on the flash drive, no drive recognition in system profiler or disk utility and it's also dead on PCs now too. If I could format it that would be one thing but nothing recognizes it now. The files on there weren't life or death but I'd like to get them back AND not have to just throw away the flash drive.
    Ideas??
