My MacBook Pro shows "the disk you inserted is not readable by this computer.

After taking my external hard drive WD 2 TB to my best friend for a few days and connecting via USB to its player Samsung Dvd/multimedia, I now have the message above after plugging back on my MacBook Pro. I tried so many difficulties, I found online, but nothing has worked. I even tried to type the command Terminal fix "diskutil repairDisk/dev/disk" and received the message "error repair card: MediaKit reports the wrong partition or no map found (-5324).

I've seen suggestions of using Disk Warrior, but that seems a little hit and Miss wise success and I can't really afford. This HD were thousands of files on it and was also my Time Machine backup disk. I really want to erase and reformat, but I don't know what else to do! Can anyone help? My MacBook is a model 13 "of 2012 and the HD is a year older. Never had any problem with before this. I realize I should never be plugged on the Samsung device now.

I eventually found a solution myself. In the case where it happens to someone else, use a program like EaseUS evaluation edition to see if your files are still there and CAN be recovered. After much research, it was clear that the question was a mapping problem caused by plugging the hard drive in the unit of Samsung Media and my MacBook could read is no longer. I ended up using Disk Warrior and it was set to 100% less than an hour. No need to format or restore data to another drive.

Lesson learned - if you use it on your Mac, connect on something else!

    I can't say if it will work, and it may even be harmful, possibly to the point of making your mac unbootable, so be careful - all the least have a clone of your system disk. If you start using the internet (Command-Option-R) recovery mode, and if your mac is a model that existed prior to El Capitan, it could be that the disk utility you get in this collection is the old version, including the order of repair permissions.

  • iMac G3 Tiger Installation "the disk you inserted is not readable by this computer.

    Hello

    I try to install Mac OS X Tiger on my iMac G3 slot loading 400mH. The system is compatible all I checked before installing. I was able to start on the first disc very well. It is installed properly, until he asked for disc 2. When I put in the disc, it turns a little, and then do absolutely nothing. It just sits there even ask for the disc. After having let it run all night, I decided that the only option was to hold the power button. When I turned the machine back on, it gave me the error "the disk you inserted is not readable by this computer. He then ejected the disc.

    What are my options?

    One thing I forgot to mention, is that I have created these disks under windows with a program called TransMac. It was the first program that I found which could create for Mac bootable discs. The fact that he created the first a perfectly fine leads me to believe that it is not my Windows and Mac computer. I could be completely wrong, and if so what is a better program. I am not of any other Mac other than the G3.

    Thanks in advance!

    Other specifications:

    iMac G3

    400mH

    256 GB RAM

    120 GB disk with Mac OS 9 and OS X Panther (I'm trying to update for Panther)

    Historically, the Mac have trouble starting from system disks burned. As you say, the first one worked, so you might be on the right track. Have you tried to make a new second drive from the same program? Maybe there is a media problem or an engraving error.

    The other problem could be the source of installation of Tiger. Apple has distributed never freely as each copy that you find on the internet - free or paid - are pirated and may even be compromised. It happened more than you think. There are a lot of reports of people for an OSX version here as an internet download and even pay for it, only to find that it works at all. I've seen downloads Mac OS offered for sale even on sites like eBay (I point out them).

    So this begs the following question - where did you Tiger?

    If we get that worked, we ned to continue what I have some experiences with Panther and Tiger on the iMac of the same model which can be useful

  • My Macbook Pro gives me a message saying: external drive is not readable by this computer. But he worked Twitter.com. What can I do?

    I tried to move my music and my pictures of my Macbook Pro 2012 to other Macbook Pro 2009, but the older one is absolutely remained stuck. So I unplugged. Now, it will not be read by Macs, and give me a message, the external drive is not readable by this computer. Both are running on the same iTunes updated and Maverick. What can I do to recover thousands of photos and CD?

    The disc in particular is either corrupted or has failed.   If you don't have a backup, you find yourself working with a data recovery service, which will not come cheap, and they don't guarantee any results - to try to shoot everything that is left behind.   Reformatting the drive - if it has corrupted and not failed - could bring the disk itself to the utility, but that won't help with any data on the disk.

    Whenever I enter my correct password in my windows account it rejects a message and it comes up saying: "you cannot connect because the logon method, you use is not allowed on this computer." See your network administrator for more information. "I can't seem to be able to enable or disable anything because the profile I'm using on my computer is the profile of"Guest ".

    Karima,

    Applicable to Windows 7.

    The following steps require administrator credentials.

    • Use the Windows + R or "Run" in the start menu, then type gpedit.msc.
    • Navigate to Computer Configuration > Windows settings > local policies > user rights assignment > consider all policies "prohibit the newspaper on" to check if your guest account is listed. Remove account from the list, and you should be fine to continue using your guest profile.

    Good luck.

  • The disc you have inserted not readable by this computer. What?

    I have been using an external hard drive (usb) for a few months. As I was falling images to save the disk I got an error that the disc is not readable. I have important files out there that has not been supported until a second source, how to make my computer to recognize the drive without formatting! I can also see it on my disk utility, but it won't allow me to repair the disc until I have format. What are my options?

    Try resetting the SMC and LANDAU with disconnected JEP, then re - connect and test. If you used another drive as your Time Machine backup, then the DHM has probably also been backup on it. If she has no HD doesn't have, so you can try the recovery of data such as DiskWarrior or DataRescue software and so those who fail, you may contact a data recovery service. Go on, ALWAYS make sure you have a redundant backup of all your data.

  • No wireless networks not found on laptop - the WiFi windows service does not work on this computer

    Hello

    I have a laptop model Toshiba P205-56347 running Vista home premium and a lynksis WRT54G V8 router model.  The WLAN light is solid and the internet light flashes on the Linksys.  I have Comcast cable as my ISP.

    I've seen reported similar problems.  All of a sudden my wirless acess stopped working, some networks are displayed and I get the message 'windows wireless service does not work on the computer.  I am not able to restart the windows wireless.  I can't connect to the internet on the laptop.  I have a DELL PC and can access the internet here if necessary.

    In the network and Discovery Center, I see that network discovery is disabled.  I can't set it to on.

    Under system devices, I have the following network cards: Intel (r) Wireless WiFi Link 4965AGN and Realtek RTL8101 Family PCI - E Fast Ethernet NIC (NDIS6.0).

    Help, please.  I'd appreciate any help.  I need a good starting point for resolution and wouldn't start using suggestions that corrects other issues.  I design financial systems and purchase online, but I'm not a technical person with regard to updates Vista, drivers, etc..

    Thank you! After reviewing the responses to similar problems, can anyone suggest if I should try one of the following values: 1. run SCF/scannow at the command prompt I don't know what that's going to fix it and do not want to make the current problem worse. 2. download the driver for the network drivers. If you would be grateful if someone could help me find the driver and download it. 3 reinstall Windows Vista Home Premium SP1 since the restoration of Toshiba CD I would appreciate greatly any information. Donna

    Hi blondswede,

    You can try running sfc/scannow to see if you have corrupted files. That won't be a further problem on your pc. After that, you want to make sure you have the latest drivers for your laptop, especially drivers of the NIC (network card). Go to the following link to Toshiba for your model and download those:

    http://www.CSD.Toshiba.com/cgi-bin/TAIS/support/JSP/modelContent.jsp?CT=SB&OS=&category=&MOID=1757721&RPN=PSPB3U&modelFilter=P205-S6347&selCategory=3&selFamily=1073768663

    If you're still having problems, and it has recently emerged as a problem, you can try to restore your system to a point in time before the problem started to use the system restore. Here are the steps to follow:

      1. Click Start, type system restore in the search box, and then click System Restore in the list programs. If you are prompted for an administrator password or a confirmation, type your password or click on continue.
      2. In the System Restore dialog box, click on choose a different restore point and then click Next.
      3. In the list of restore points, click a restore point created before you started having the problem, and then click Next.
      4. Click Finish.

      The System Restore tool

      If the problem you are experiencing started occurring recently, you can use the System Restore tool. Using this tool, you can restore the computer to an earlier point in time. The tool using System Restore may not necessarily help you determine the problem. When you use system restore to restore the computer to a previous state, the programs and updates that you have installed are removed.

      To restore the operating system to an earlier point in time, follow these steps:

      The computer restarts and system files and settings are back to the State they were in when the restore point was created.

  • The Sierra of MacOS will propose for the Mid 2009 MacBook Pro in the near future?

    I have a model Mid 2009 MacBook Pro and when I try to upgrade the software of OS systems to the Sierra, he refused my request to download because it "cannot be downloaded to this computer." I noticed other Mac computers, for example, iMac Mid 2009 or newer and MacBook Mid 2009 or more recent systems only one are close to mine are candidates to download the software, but the MacBook Pro is the only one that is not on this list for availability. So, my question to my question is, will be available Mid 2009 MacBook Pro updated to day for Sierra anytime soon? And if not, why?

    Please let me know what your answer is as soon as possible.

    Thank you!

    My answer is no.

    However, as long as I and everyone here, do not work for Apple, my answer is certainly not authoritative.

    However, as I've used Apple computers for more than 30 years, he never had a case when they released an additional OS that works on previously excluded material.
