• 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.

• WD external drive is not detected by the Windows backup program

  Original title: with a WD external drive backup program

  I have a WD My Book Essential 320 GB external drive. The Windows backup program does not recognize the drive... The drive IS recognized on my computer and I can access and transfer and copy and paste to it without problem. It's just the backup program which does not. No error message or anything. Only, it does not recognize the drive when I get to the destination area. I tried to update the drivers. The WD support site has Backup downloads for OTHER external drives, but not this one. Their Web site says to contact Microsoft support. Any suggestions?

  Hey mrlray,

  Here's what you can do.

  Perform the clean boot

  Backup process a lot sometimes, this problem is provided by third party in conflict with windows software. See if this is the case here by putting your boot system before you perform the backup.

• WD My Passport drive external drive will not mount once my Macbook Pro is already on

  Hello

  I actually had this problem for a year or two, but I'm finally getting bugged to this topic enough to see if it can be 'fixed '.

  I have a 2 to WD My Passport portable HD connected to my macbook pro via an external (wall outlet) powered TRUST 5 x USB3 Hub.  If everything is connected, when I start the macbook pro there is no problem and the WD My Passport is mounted in the finder.  But if I remove manually the hard drive and then try to mount it again while the macbook pro is running it doesn't mount not.  It used to, but he won't now.

  In the past the WD My passport would need to unplug and perhaps the USB3 hub would need power cable disconnect from him and the USB hubs out the macbook pro.  So when I joined this new and plugged the hard drive WD in the hub, it would rise very well.  But now it's just point blank refuses to ride until I restart the macbook pro.  Once I restart it it climbs perfectly and stays up forever--until it is dismantled manually - and then I have to restart the macbook pro again so he could mount once more.

  I tried all combinations of pull cables and adapters to power but nothing has worked.  After dismantling the WD hd and plug back on the USB3 light led on the hub hub lights up and the hard drive turns manually, but, as I say, it is not mount and it is not visible in disk utility.

  Any ideas please?  It's a bit annoying to have to keep restarting the mac whenever I had to unplug the hard drive WD.

  "As issued" WD Passport appear to cause a number of reports of trouble around here. You have already taken the first "not best" - using a powered hub. Just make sure that the hub is really power (lights on, for example). It could be that the external drive is in its death throws.

  This happen if the WD is the only thing on the powered hub?

  The Mac USB ports work with other devices?

  Here's what my experience with these things has believing me. WD made great bare discs, but I can't be so kind to their pens. Three questions:

  (1) I think that they should use chipsets which are not very easy to Mac.

  (2) most driving the ship formatted for Windows

  (3) even those shipped as "Mac editions have some odd which makes it difficult to access file formatting.

  If you do not have to share the drive with a Windows computer, you can reformat the drive and that often fixes "fail to mount/recognize" question. Disk utility is your tool of choice here because it is already installed on your Mac. Completely erase the WD drive by selecting the tab 'Clear' in the bar tabs to disk utility. Define the plan of Partition to GUID Partition map and journaled for Mac extended format. Press the button 'clear '. The reader will now will be rid of eccentric WD partitioning and formatting schemes and be a good Mac hard drive.

  If you share the road with a Windows computer, consider getting a better workout. After having fought external drives 'brand' on my computers and others that I maintain, I now use only boxes of other computer world with naked WD drives inside. Since this change, I have zero problems. For my MacBook Pro, I use this forum:

  https://eShop.MacSales.com/item/OWC/MEPMU3ES/

  I ordered the external power optionally for use at home and go on the road bus-powered. It's an empty envelope - just a hard drive of nu. They are more expensive than the stuff that Staples puts on sale every weekend, but are much more reliable. I ask the question. "What is my value data?"

• Drive external DRIVE will not mount after resizing in Windows

  Hi all

  I got a 1 TB external drive that I used for a while about 10 Windows and OSX (El Capitan). I had two partitions Configuration for use on every platform without any problems.

  Then, I needed extra space on the Windows partition, so I think that, if I remember correctly, that I've resized using the disk management tool in Windows. I reduced the OSX volume and increased the size of the Windows volume. I can probably hear you all shout now.

  Surprise, my volume OSX will now not mount when I run in El Capitan. It does not show in disk utility, and the only way to 'see' it is using diskutil:

• External drive is not accessible by Time Machine or disk utility

  I have a USB drive connected on my MAC (OS X El Capitan) the drive has 3 partitions, one is used for bacp of documents (200 GB), empty (300 GB) and for the backup copies made with Time Machine (300 GB). Since yesterday, Time machine does recognize more the drive for the installation of the most recent reserve backup copy, The Time Machine, the disk partition is also not found by Finder and when the drive is connected via USB to the MAC, disk utility does not but rest in mode search, without giving any information.

  The MAC system information indicates that all the three partitions connected via the USB bus, ar

  I can't remove the disks with the indications of the boom, but when I remove them physically a warning I thay sgiven the duisk has been removed as not appropriate.

  I think that something is wrong with the partitioning of the disk, but I see no way to retrieve the disc.

  Does have same problem or if it can indicate a path to a solution of the problem.

  Stop

  Remove all external devices except the keyboard and mouse

  Restart and rest the PRAM

  How to reset the NVRAM on your Mac - Apple Support

  start in safe mode

  Try safe mode if your Mac does not end commissioning - Apple Support

  Reconnect the drive (and any other external devices)

  If the disc is not visible in disk utility, you can try to connect to another computer and check it or reformat if all else fails.

  a disc formatted in anything other than extended journaled Mac will not be usable with Time Machine. If you need to reformat the drive in NTFS or FAT or ExFat, format Windows PC then reconnect to the mac, once the drive is recognized, reformat with extended Mac.

  It is also possible that the drive is dead. If it is still under warranty it can be replaced, but manufacturers don't offer a premium-free data recovery. see the manufacturer's Web site. you will need the serial number of the drive.

• folder on the external drive does not open in a new window

  on iMac OS 10.10.5, when I open a folder (by double-clicking) on an external drive, the folder does not open in a new window, but in a window that replaces the window that was opened.  I looked for a system setting that controls this (in system PREF), but I couldn't find anything useful.

  If you control - click the folder there is an option to open in a new tab. I don't know of anyway to set up in system preferences.

• Windows Vista Business 32-bit external drive does not work in the administrator account

  Hello, I installed Microsoft Windows Vista Business 32-bit on a Dell Precision T3400 workstation, and I have also configured the strategies of groups for Non administrators. Basically, I disabled the removable drives, 'C' and had "only for non administrators." After edit in GP, the system has been precisely set and I am able to access the Administrators account and copy stuffs from my local drive on my USB key. But a few days later, I'm not able to use my USB or other external drives in Administrator account, it shows that 'inaccessible '. But I can't access local drives 'C' or '.

• C drive is not visible when you try to defragment

  Original title: errors of Volume disk, drive C is not visible when you try to defragment drive C in the maintenance of the system

  I tried to do a regular defrag of my C drive and received a message that there is Volume disk errors. The utility asked to reboot the system and clean the C drive. But when I access the defragment utility, drive C is not present there to use the application... suggestions?

  Hi Dante62,

  I suggest trying these steps provided below and check if the problem is resolved.

  Step 1:

  a. right click on the c drive.
  b. Select Properties.
  (c) under the Tools tab.
  d. Select Defragment now under defragmentation.

  Step 2:

  Try the SFC scan on the computer.

  SFC/scannow is a very useful command that you can use in any version of Windows. When the SFC (System File Checker) command is used with the/scannow switch, the tool analyzes all the important files of Windows on your computer and replace if necessary.

  Check the link for more information on CFS below mentioned scan.

• External drive is not accessible

  Hello

  I have an external hard drive that I have it plugged into the PS3 and it was not legible for her so I plugged the PC and its happened.

  Please tell me the solution if you know.

  File system: FAT32

  Thanks for your help.

  

  Long-shot chance that the drive can be repaired using the check disk from the manufacturer of the car.

  You must first know the manufacturer of the drive.  Then search for tester for the reader program 'brand '.  Download the program and run it on your PC while the external drive is attached.  Remember to point the program to the K: drive.

  A few times, the program will search for errors and offer to fix them.  But he will warn you it will erase everything on the drive.  Sometimes, mistakes are small and the fix does not damage data.

• Drive external drive is not accessible, access denied.

  My computer (Win7 Home Prem) ran chkdsk after an update of windows, probably triggered by ccleaner or glary utilities. My external hard drive was plugged during the update, reboot and chkdsk. The chkdsk command probably checked my coz external HD, I can see folders/paths that were there. The next day I couldn't access my HD due to a mistake, saying: it was not accessible and access is denied. I searched online potential solution and tried the following without success, and they have been applied using an admin account and an admin cmd.

  * Change the permissions and ownership, but the property always says it's impossible to determine the owner.

  * Changed the share permissions.

  * Do you have 'takeown' and a 'icalcs' has changed owner but same error.

  * Check the disk management, drive seemed ok with the letter drive and all.

  * Ran chkdsk /F on both of my C: drive and external hard drive, both completed successfully without error during the analysis and not found bad sectors.

  * Program of Unlocker used to check if player was running another process, found nothing.

  In my computer, it shows the letter drive and NTFS, but not bar showing free space. Properties would show 0 free space / used. Here I can go to cmd and access the content from there. I used the function of 'Explore disk' of glary Utilities and I could see the content and even run mp4/avi files in the player. So I guess the drive and its contents is ok, just that I can't access it through normal means.

  Thanks in advance!

  Hi LeBlanc,

  I apologize for the late response and can certainly understand your concern. I appreciate your efforts. As you mentioned that you are not able to access the external drive, and you receive the error of access denied when you connect to your user account, I suggest to try to create a new administrator user account and then try to access the external drive.

  To create a new user account, please follow the steps mentioned in the link below:

  Please let us know if the problem persists.

• The drive letter for the files on my external drive does not match the designated letter MyWindowsApp, after briefly changing pots

  On my Windows 7 laptop, I briefly moved an external hard drive to a USB port to another and then back.

  The reader is referred to as F, as it was originally, but since the temporary move the path for some files now show that E.

  I went to disk management and confirmed that the drive is detected as F.

  This disrupts programs such as Adobe Premiere Elements. It always hurts new information loaded in the disc I load that is in F, but the said path E. The file is clearly on record.

  Hello

  I see that, after changing the port, the drive letter for the external drive has changed. I'll help you with this problem.

  1. What is the brand and model of the computer?

  2. what security software is installed on the computer?

  You can follow these steps to assign a letter to the external drive and check if that helps.

  1 - click on 'Start' button.

  2-right-click on "Computer" in the list that appears.

  Option 3 - Select the 'manage '. If a warning appears asking for your permission to continue, click on the OK"" button.

  6 button - click on the 'change' in the window that opens.

To the right of the present is a drop-down list with the drive letters currently not assigned to all of the drives on your local system. If you are not on a network, choose the drive letter you want for your USB key and then click on the OK"" button.

• 'Open the connection' VM on external drive does not always open when connecting

  Hello community,

  I have a MacBook Pro with 10.6.8.  For technical reasons, I can't upgrade to a newer version of Mac OS X.  I have a license for VMware Fusion 2.x and I'm using the latest version of VMware I am legally authorized to use, 2.0.8.  For technical reasons, I have to stay with what are free upgrades I have the right to use.

  I have a guest to Solaris that resides on an external drive.  I want to make sure this guest operating system starts when I connect the MacBook Pro.

  In the finder, I put VMware fusion as "open at Login".

  In the library of VMware, I put the to Solaris comments for "Open when VMware Fusion begins.

  Sometimes the comments of Solaris OS * fact * start automatically, sometimes it does not.  Can someone help me make sure it * still * starts?  I'm not yet able to determine why he still does not start.

  Thank you

  Ed

  If Fusion launches before the external drive turns and rises in the finder, it will not see the virtual machine and does not start.  Launch of Fusion manually or power cycle external drive so there ' hot' before you start.
