  How can I know if an external drive has been used for Time Machine and what computer it came with too?

  I have several laptops and iMacs. I spent the relocation of the year and only used the MacBook Pro.

  Now I'm trying to figure out which drive goes with which computer

  I connected just a disk seagate 1.5 t and the first thing he did was to ask if I wanted to use it as a Time Machine drive.

  (1) if it is the TM disk accompanying this computer don't would not it have just started upward automatically?

  (2) what happens if I would have said yes?

  (3) I don't even know if it's been activated for TM. Is there a way to tell? It may hold just for iMovie files and other programs associated with a computer from my past.

  All readers of backup Time Machine contains a folder named: Backups.backupdb. If you open this folder, you'll find another folder with the name of the computer that has been saved. If several computers have been saved on the same disk, you will have several folders.

• 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:

• MP3 player via the USB port (no matter which), it keeps coming back as the "Drive is not accessible. Access is denied. "

  Hello

  So, here are the problems I encounter, and what I did to try to fix myself.
  Whenever I try to connect my MP3 player via the USB port (no matter which), it keeps coming back as the "Drive is not accessible. Access is denied. "  This same thing happens everytime I try to put an SD card in the SD card slot.  However, despite this, I can plug my USB mouse and use it, as well as the keyboard and it records only.  I can also use the HDMI port to use my TV as a second monitor and, also, to record that.
  What I did to solve the problem, it is to restore the system to the previous times before that happened, did not.  I also went into the Device Manager and uninstalled and re installed, USB and SD card drivers.  I also tried something in the sense of taking control of the files via a right click on a folder and go to properties and then security and to the 'advanced settings', the problem with this situation is that I can't in readers at all.
  I am currently running Windows 7 (64 bit) on a laptop Lenovo, the computer itself is actually only a few months.  If someone knows something about this, please let me know.  Thanks in advance.

  Have you tried to update the CD/DVD drive?
  You could go to the Device Manager and could remove the reader of CD/DVD from the list of devices.
  Then, you must restart the laptop.
  After restarting again the Windows operating system will recognize the new device as the CD/DVD drive and will initialize and reinstall the driver.

  Then try using the new CD/DVD drive

• 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?

  Sorry, you can not. A CRC error means that there is a serious problem with your drive. You need to replace it.

• Hard drive is not reflected in the list of disks

  Device Manager recognizes a disk but the disk management does not show in the list of disks (affected/not allocated).  You want to set up and assign a drive letter.   Thank you.   Russ

  < original="" title:="" disk="" management="">

  Hello Russell,

  Thanks for posting your query on the Microsoft Community.

  With the publication of the description, I understand that the hard drive is not reflected in the list of disks on your Windows 7 operating system. I will certainly help you get this problem.

  This problem can occur because of incorrect settings. In order to solve the problem, I would suggest trying the following methods and check if this is useful:

  Method 1: Troubleshooting hardware and devices

  Integrated the hardware and devices troubleshooter can automatically detect and fix most of the incorrect settings and errors that could cause problems with the equipment. I suggest you run the troubleshooter to check if there is no problem with the graphics card. See albums as follows:

  1. open Control Panel

  2. click Troubleshooting and select the option to display all on the left pane.

  3. click Troubleshooting of hardware and devices and follow the prompts.

  Try Method 2, if the problem persists

  Method 2: Make sure that the drive is enabled

  Follow the below mentioned steps to make sure that the drive is enabled:

  1. click on start and type device manager in the search box

  2. click on Device Manager in the control panel list

  3 locate the drives item in the list, and then click the small arrow to the right to expand the list of readers

  If a disk is disabled you will see an icon with an arrow pointing down on the icon of the hard disk

  If you see an icon with an arrow pointing down on the hard drive icon, double-click the icon and click on the button Activate peripheral

  4 then click on activate a device dialog box, click Next, and then click on finish

  5. click Close, and then close the Device Manager window

  Note: If you do not see your hard drive in the listed readers, the player is not detected by Windows.

  Note: If you receive an error message when the hard disk is activated, you can have a bad hard drive.

  Hope the helps of information. Let us know if you need help with Windows related issues. We will be happy to help you.

• Peripheral USB take two tests at work and does not start with Time Machine drive connected

  I have a 2015 mid Macbook Pro 15 "work (so I can't afford to take this service for a period of days). My specs are:

  

  I am running the latest version of El Capitan, 10.11.4.

  My problem is that USB devices - such as Logitech USB headsets, USB sticks, external hard drives, etc. - always and I always say, require two plugins to be detected by the system. It doesn't work the first time. I always have to connect once, remove it and plug it in again.

  In addition, if I try to boot the system with my Time Machine/external USB HD drive, it won't start at all. Only if I reboot without all the devices connected it boot successfully.

  My questions are: is it a software or a hardware problem? And someone saw this before? I think it's a hardware problem, although the last notes of patch involve the last update of OS may have addressed a similar issue with audio devices. (This would affect my Logitech USB headset no doubt, but it did not help). If it is a hardware problem that requires a fix of the motherboard, I can't do it, since the new it's a working machine that I can't part with for a long period of time, unless SHE is willing to trade me a machine on-site. It does not affect other most operation every day except that I need to plug devices twice, all the time.

  Thank you, everyone.

• External network drive helps to work with Time Machine

  I did research on my brain for the last 2 days on this subject, because I have to remove a ton of material from my laptop before he goes kaput (spoke yesterday on another post)

  Here's the plan... I think so:

  I want to move photos, films (home movies not DVD) and the iTunes library from my MacBook Pro to an external HD attached to the wifi router, so I don't have to be hard wired to access photos, music, etc., then at home.

  I want to continue using Time Machine to back up a) my laptop and b) the files moved to the external hard drive.

  This will require a SECOND external drive.

  My understanding is that this is possible if the SECOND external drive is connected ONLY to an 802.11ac Apple Airport. No other wifi router will not work.

  The airport could be connected by ethernet to an existing Netgear wifi router that Comcast installed in order to manipulation of our home security system.

  Is this possible? It is frying my brain.

  Or...

  I do one) get a time Capsule 2 TB,

  (b) plug on the Netgear

  (c) to charge all my top media and

  (d) connect a 3 TB drive in the time Capsule to back up what is on it and my laptop?

  Does it work?

  It kills me.

• Duplication, but restoration not Photos of Time machine

  I have a large collection of Photos stored on my external HD that contains thousands of faces defined. Trying to solve a problem of random reboot on my new iMac, by Apple, I eliminated the files of faces in the Photos on this computer, but believe that the face IDS are intact on the external hard drive because it has not been used recently for TM backups. The last time that he saved, he supported Photos that still had the names linked to the faces. Before I take the Time Machine, I want to copy the Photos, including the names of face, of a flash drive for safes (and possibly add that the names back into the Photos once that resolve us the problem of random restart). But I can only figure out how to 'restore' Photos of Time Machine. I don't want to restore the old file Photos, because the Faces can be the source of our problem of ransom-restart. Instead, I just want to download my last copy of TM's Photos, including the names, on a drive connected to the iMac. Can someone tell me how to download the most recent file of Photos of my external hard drive to a flash drive without updating the files of Photos now running on the iMac? Thanks for the tips!

  You can not copy pieces of backups TM TM don't just clone files but save changes and maintains a database showing how to reassemble the file from a specified date - you can use the software TM to restore the things - you can restore to an alternate location and then select the restored library - however It is not recommended to make changes to the content of the photo library using external software because the library is a very complex SQLite database and any change can corrupt him causing loss of data
