My Macbook suddenly won't read my usb drive..

My 2012 Macbook Pro Retina suddenly won't read my usb drive (its a Kingston 16gb DataTraveler se9 if it matters).
I was just using it yesterday and it was just fine. Did the drive just fail? Or could it be something with the Macbook?
It shows up on disk utility but verify and repair disk is greyed out. This is the first time I've had this problem in 15 months
of use. My Lacie external drive still works just fine and I tried out another se9 and it worked fine too..

Thanks, but my drive is accessible through disk utility, but when ever i attempt to verify it or repair it, disk utility just doesn't respond and i have to force quit.

  • My Macbook Pro suddenly won't read my hard drive.

    My Macbook Pro suddenly won't read my 750GB WD Elements Hard drive.
    It was working earlier today but when I went to press play on my TV show in VLC it said the files couldn't be read. So i reopended them all and they still didn't work. I closed down all programs running that could possibly be using my hard drive but it said it was being used so I force ejected it and when I plugged it back in it didn't work.
    It comes up with an error message "this disk can't be read by this computer" but it still shows up in disk utility. In disk utility though it says it is a 2.2TB hard drive which confuses me. also I the buttons for "verify disk" and "repair disk" are greyed out.
    Is there something that I can do to try and get my hard drive working again?

    If I'm not mistaken, this drive is bus-powered. MBPs seem to have frequent problems with bus-powered drives, probably because they don't provide enough power on the USB bus.
    In disk utility though it says it is a 2.2TB hard drive
    It is possible that the drive or USB interface are damaged. However, it is too early to decide. You need to connect the drive to a desktop machine (Mac or PC), or provide more power to the drive (with a power supply, if the drive accepts it, or a USB Y-cable and a USB power supply, rated 1A or more).

  • MBP/iBook won't read repaired USB drive?

    I have an ativa thumb drive I've been using for a few months now. In the past few days suddenly my MBP (also an iBook) gives me the message "Disk you've inserted cannot be read by this computer - Initialize / Ignore / Eject."
    So I opened Disk Utilities and ran 'repair disk' and it said minor repair was needed to the header. Ran repair disk it says disk is repaired. Run verify disk and it stops saying the header needs minor repair. Run repair disk, it says disk is repaired. Computer still won't read it.
    I boot up from my startup disk and again open Disk Utilities from there. Run Verify Disk and Repair Disk and both say no repairs are needed? For grins I checked my HD and a minor problem was found so I ran repair disk on it. Disk Repaired. I've rechecked both drives nultiple times and each time the reslt is no repair required.
    I launch from my on board system (i.e. without startup disk) and again computer says disk can't be read - initialize / ignore / erase? In fact I get 5 windows with that same message in rapid file on my screen.
    Any idea what gives? If both drives are OK - why won't it read the info as before???

  • MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

    MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

    dohdoh1985, I have the exact same problem also! I recently bought a 42" RCA LCD TV. I connected my MacBook Pro to my TV using a Dynex Mini DisplayPort to HDMI adapter that I got from BestBuy. It worked great until I upgraded to Mac OS 10.6.4 and then it suddenly stopped working. Same TV, same settings, same cables, same adapter. Nothing changed since the last time it worked except that my OS was upgraded to 10.6.4, so i am assuming that is the culprit. The symptoms are EXACTLY the same as what dohdoh1985 described; when I plug in the TV, the laptop display flashes (3 times) as though it is detecting an external display and the picture on the TV briefly goes from blue to black for about 1 second then back to blue. The TV does not appear in the display menu / control panel and there is no sign that the MacBook detected it. I went through the usual troubleshooting steps (reset PRAM, checked connections, tv settings, etc) but nothing worked. Other HDMI sources (i.e. Blu-ray player) work fine on the TV using the same HDMI cable on the same port so there is nothing wrong with the cable, the TV or the TV's input settings.
    Meanwhile, I can still connect my MacBook to my external ViewSonic monitor at work without any problems. It's just the TV that's not working.
    I cancelled my cable subscription a while ago since I only watch shows online nowadays and this was my only way of watching TV shows, so I'm quite upset.
    Apple, please help!

  • Macbook pro won't read discs

    macbook pro won't read discs. I have tried resetting the SMC & the computer itself. Any ideas

    What exactly happens when you try?
    Have you tried both DVDs and CDs?
    Try a cleaning disk.
    Otherwise it would seem that the optical drive failed.

  • Macbook Pro won't read Windows XP disc

    My Macbook pro won't read either my 32bit or 64bit windows xp discs for installation on bootcamp. The disc spins, makes a strange noise then ejects. It seems like this is a common problem. I have previously installed windows via bootcamp before and it worked fine. Normal cd's are read fine as well, just the windows discs won't read.
    Any suggestions?
    Thanks.

    Hi,
    first: put your XP 64-bit CD as far away from your Mac as you can. Apples BootCamp does not support it
    Second: I assume corectly that these are Retail or SystemBuilder XP discs, not some Recovery CDs or manufacturere-branded ones, right ?
    Third: insert the 32-bit XP CD while in OSX and check with the Finder if it can be read there (checking for the 'usual' folders on it: i386, Support, etc and files: winip51.sp2 etc.).
    Fourth: some people round here have successfully used a 'standard' DVD/CD-cleaner disc with their Macs.
    Fifth: try making a 1:1-copy of your XP disc. You can use SimplyBurns in OSX for this.
    Regards
    Stefan

  • My iMac won't read my flash drive

    My iMac 27-inch, mid 2011, (OS X version 10.7.4) won't read my flash drives. I don't believe it is a formatting issue of the USB flash drive because the flash drives are easily read on my MacBook Air, 11-inch, late 2010 (OS X version 10.7.4). The drive occasionally will appear on the iMac, but not always, and I can't seem to figure out when it does and when it doesn't. When I use an external hard drive, it appears in the finder.  Just, not the flash drives.  So, I continually have to load from the flash drive to the Air and then connect to the iMac. It's kind of ridiculous. Does anyone have an idea why I can't read the flash drive on the iMac?

    Could be a USB port glitch/problem - try these two troubleshooting methods:
    PRAM reset:

    post back if it still doesn't work.

    Well then when you erased your hard drive, your erased the Recovery partition, also.
    Use Internet Recovery to either restore from your Time Machine backup or reinstall the OS if you don't have a TM Backup.
    It will install the OS that shipped on that Mac. You can then upgrade via the App Store.

    Zap the PRAM and Reset the SMC, then try again.

  • My macbook pro won't read dvds from my external cd/dvd drive.

    I have a new macbook pro 13 that I got for Christmas. I purchased a external cd/dvd usb drive so that I can watch movies on my mac since it doesn't have a dvd drive built-in. I put my dvd into the drive, and all my mac does is open a fiel that has the video and audio seperated. I tried clicking on the video file to see if I can watch it, but the computer has no software to read it, apparently. I don't know if this is a software thing or if it's my drive.

    First, try one of the DVD drive cleaning kits that are available.

  • My MacBook Pro won't read my WILCO, Sky Blue Sky cd

    I have an unusual problem...My MacBook Pro won't open my WILCO, Sky Blue Sky cd. I've had to restart my laptop while pressing the mousepad down to eject the cd which keeps getting stuck whenever I insert it. I have burned this cd on my PC laptop and wondered if there's a certain "lock" on the cd after that but I've researched this scenario and found no mention of such a case online. Luckily, this is the only cd my MBP can't seem to read at all. Where other cd's I insert launch iTunes and appear on my desktop, this particular cd doesn't and it freezes iTunes if I test its Eject function on it. My disk utility can't read it either and puts it in a perpetual "Gathering disk information..." mode. Pls help...this is a legally purchased cd and I should be able to burn it on more than one computer I personally own...This is really strange as I've had no other problems with other cd's or dvd's on my Mac...

  • MacBook Pro won't read audio cds

    My MacBook Pro will not read digital audio cds.
    It has in the past, but now it seems to have stopped reading them.
    I have several purchased cds I would like to get on itunes, but I can't get it to recognize the discs.
    I can hear it spinning several times, like it is trying to access the disc, then it ejects it without mounting.
    It does not appear in iTunes, or anywhere on the desktop.
    It will read and burn blank cds and dvds.
    I havde a 17" MacBook Pro, 2009, with a MATSHITA DVD-R   UJ-868 drive.
    Anyone have any ideas how to get it to work again or what the problem could be?

    yes it could but probably not after testing ten different CDs right? Got the very same scenarion and asked the question again here, pls see https://discussions.apple.com/message/22423010#22423010

  • New i5 MacBook Pro won't read or play certain DVD's

    Just got a new i5 MBP and it won't read certain DVD's that I put in. It tries to read them but then spits them back out after a few seconds. Any thoughts?

    If you talking about movies, It might be a simple case of region. The first time you insert a DVD movie your mac asks for your region and you can only play DVD movies from the region you selected. If i'm not mistaken, VLC might not have these restriction and will play any region formated DVD movies.
    You have the ability to change the region that you've selected but be careful cause you can only change it an x amount of times.
    If you talking about regular burned DVD than it might simply be a problem with the disk itself. You should test them out on another machine to determine if your MBP has an issue with its super drive.
    Hope this helps.
