  • USB flash card doesn't work

    Hi,
    I' ve just bought a new Transcend 16GB USB flash card. It works properly when I move files from it to my Macbook Air running Lion.
    When I try to move files from the Mac to the flash card, the copy doesn't start and the system stays blocked in "calculating remaining time".
    I tried to format it with FAT32 and HFS but nothing changes.
    On Windows7 (installed as well on the Mac) the USB flash card works perfectly in both ways.
    Can u help me?
    Thanks
    Marco

    I tried with another USB flash card and with a smaller file.
    The transferring from Mac to the card starts but is extremely slow ( around 0,5MB/sec)

  • 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.

  • Unable to boot from my USB Flash Memory Device

    Hi there,
    I recently purchased a macbook pro with the lion 10.7.2 firmware.
    I am experiencing problems with my USB Flash memory as when i plug it in it comes up fine on the desktop and i can browse it. The problem is that when i open up an application such as Adobe Fireworks or Netbeans (Java programming) and try and access files from my USB flash drive, my drive does not appear on the list/menu, it only comes up with my macbook pro documents etc.
    I have asked friends with Mac's and they tell me they do not experience this problem. Please can you help me whether it is a problem with my settings or any other issues.
    Thank you.

    Nope, I dont recieve any massages at all. It just doesnt appear.
    Also usually you can drag a file into an application, for example drag an image into photoshop in order to open that image up but this does not work either.

  • I've bought a new USB flash memory. I plugged it in the USB port then a message come out: Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.... Please help...

    I don't know what to do. I plugged that USB in both ports but the same message came out. I charged my laptop and the same thing happened again. The surprising thing is that I tried plugging the USB in my cousins laptop (Macbook Pro) and it worked!!! but not with mine. The USB flash memory made by PNY. Please help...

    There are two types of USB 2 devices - low power which consume 100 milliamperes or less from the USB bus and high power which consume up to 500 milliamperes. Your flash drive is probably a high power device and is overloading the USB bus of your computer. (Some notebooks can support only low power USB devices.)
    I know that my MBP's USB ports support high power devices but I've come across reports that not all high power devices will work on the MBA and that might be the case for your flash drive. My guess is it has a large capacity? 32GB or more?

  • USB flash memory: "application not found" error

    When recently trying to use a USB flash memory stick I was getting an "f:\ application not found" error. I tried all kinds of fixes from Microsoft. Turns out it was caused by Lightroom.
    Since the memory stick had photos on it, my computer's Autoplay was trying to launch Lightroom. Problem is, Lightroom is listed as "Lightroom 4.0 64" in the Autoplay menu. I have Lightroom 4.4.  As far as I can tell, there's no way I can fix the incorrect "Lightroom 4.0 64" listing.  The solution is to remove Lightroom from any Autoplay options.
    This is the second such problem I've had with Lightroom.  The previous problem was right clicking on a photo file and trying to use the "open with" menu.  It worked fine when I had Lightroom 4.3.  After updating to Lightroom 4.4, it didn't work. Another Lightroom user found a workaround, which was to rename the Lightroom 4.4 folder back to Lightroom 4.3.
    These are both lazy Adobe oversights. You have to realize all the Windows functions that will be affected with an update and make sure they are updated as well. I spent half a day solving this latest USB flash memory error. Get your updating act together.

    You don't mention your OS or which version of Outlook you're using.
    For Windows, this may be helpful:

  • Toshiba 40SL733g - How to play video files from USB flash memory

    When I plug my USB flash memory in USB port, Media Player menu shows up with two options : Photos and Settings.
    How do I make my TV recognize and play video files from USB flash memory?
    Flash is on FAT32.
    I have tried to play avi, mp4 and mkv files but nothing happens. It looks like flash is empty.
    Could you please help me solve this problem.
    Thanks!

    bzunic, have you updated the firmware for your model?.
    With my own set, (32RL900A), the instruction manual said that certain buttons on the remote control were "unused", however, after the first firmware update, the previously "unused" buttons were used, (In our case, Time Shift, Record, and so on).
    The reason I talk about this is, these features became available after a firmware upgrade, and were not mentioned in the user manual, in our case, and a later download of the instruction manual for our model actually gave the instructions for the use of these features, which were shown as "not available", in the original instruction manual supplied with the TV, but became available after the firmware upgrade.
    Let us know how it all works out ............

  • Install arch voodoo from usb flash memory

    I am interested in anybody crazy enough to try this tutorial I made http://wiki.archlinux.org/index.php/Ins … ash_memory , I tested it with my hardaware and until now it was worked out great, but i am looking for second opinions.
    I also posted an updater script that will update the install packages, so you can always carry a freshly updated arch install, anybody willing to test it on any spare usb flash memory or external hd they might have, please do so.
    Cheers!

  • Making the HIDDEN File(.DS&Trashes) visible in USB FLASH Memory

    Mac always has this .DS and TRASHES folder everytime I use my USB Flash memory, and it consumes spaces A LOT. The problem is I cant see it on my PB, so what I discovered was to connect it to a windows computer to erase those hidden files.
    Is there a way I can erase/see these files on my Mac? Finding a windows computer is not always easy here, and quite inconvenient. Thanks!

    Try this, it works well for me...especially when transferring files between Mac and PC when all those Finder files show up and get very confusing.

  • Cannot play .avi files from USB Flash Memory UHYB-064GH

    Hi,
    I have recently bought a 64gb Toshiba Flash Memory Drive (Stick). It's model UHYB-064GH.
    Straight out of the box I plugged the USB drive into my Windows PC.
    I'm running Windows Vista.
    I tried to transfer a number of .avi video files to the device, taking up about 10gb of space.
    I tried running the files (using VLC player) straight from the flash drive. Most of the files wouldn't play.
    Only one did but it only played the first 8 seconds of a near 2 hour film.
    The counter in the corner only showed the film to be 8 seconds long?!
    However the properties section of the file confirmed it was a 1.6gb, 2 hour film...?
    I transferred the same video files to a different (old) drive I have and found that it worked fine.
    The drive is a FAT32 one.
    I don't really know much about these things so would be grateful for any advice
    Tom

    Try to format the USB flash memory in NTFS format.
    The FAT file format supports files up to 4GB but the NTFS format supports bigger sizes.

  • Flash Player doesn't work, either IE or Firefox.

    Flash Player doesn't work, on either IE or Firefox.  Vista 32 bit, Firefox 10.0.2, Shockwave Flash 11.1.102.62.  Reloaded Firefox and Flash.  I get the spinning circle, but video never starts on IE or FF. Settings manager works.  I'm at a loss.  Update - actually it works on most video now, except Fox Sports or ESPN, either IE of FF.

    After browsing the forums a bit, it would appear that this has been an ongoing problem for more than a month and the only 'inquiry' on the part of Adobe that I can find is one gentleman consistently asking people to report through the adobe bug/crash report process
    http://forums.adobe.com/thread/953796
    While I'm certain there have been many, many reports offered up, we have yet to see any solutions from the company, and admissions that there are issues with this product, or any ETA on expecting a reliable, stable version of Flash. 
    It would be very nice to have some feedback formally from the company.  Many users (including myself) are experiencing frequent BSOD, having to spend hours uninstalling, reinstalling and aimlessly troubleshooting our computers all because of this add-in. 
    I recently updated every single hardware driver from my manufacturer, flashed my BIOS, troubleshot memory through self-diagnostics for days, and i still have issues related to Flash.   I've tried the quick fixes suggested by (not sure if he's an Adobe official voice) user 'Chris' to no avail.
    Certainly I could offer my dump file, by what good will that do me?  Adobe, you certainly have enough crash reports to make SOME progress, please offer us up something, even if it's just to update us on any progress or research?  All we know is you want information from us, while we still have nothing from you

  • Sound doesn't work(only in firefox). why? sound doesn't work(only in firefox). why? (adobe flash player doesn't work even thought it's installed)

    sound doesn't work (only in firefox). adobe flash player doesn't work correctly, thought it's installed. can't solve the problem. i need Sound.
    == This happened ==
    Every time Firefox opened
    == don't know

    What does the Adobe test page say?
    http://www.adobe.com/software/flash/about/
    Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
    If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    You can use "Disable all add-ons" on the ''Safe mode'' start window.
    You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")
    See also [[No sound in Firefox]] and [[Video or audio does not play]]

    I think that you have multiple sound devices and their boot order changes after each reboot.

  • My external Apple USB Keyboard letters doesn't work, but the numbers do. Why and how can I fix this issue?

    My external Apple USB Keyboard letters doesn't work, but the numbers do. Why and how can I fix this issue? Also, When I open the Keyboard Viewer, the letters will highlight only if I hold the modifier key(s) "Control" or "Control and Option". I really need help with this. I don't have any other computer to try it on, so I will have to test it on a friends computer sometime. But perhaps solutions that I can try right now? Thanks.
