A bootable external hard drive reset

Hello with Superduper I made a clone of my my MACMini (Yosemite) on an external hard drive (LaCie)

Now, I want to update this clone

I can't erase all the files even with TechTools

I guess the reason is that it was a bootable disc

How to have a new hard drive, a partition, ready for all?

THKS

What do you mean by update clone?

What exactly did your test using disk utility? That's happened?

  • Initialized external hard drive not recognized

    I recently bought a Windows 8 RT tablet. When you attach an external hard drive of 1 TB with USB connection, it does not recognize the computer as being already formatted - in other words, in the disk management window, I realized to initialize the drive.  I use the hard drive to save the files (more storage than available on the Tablet) and it has been formatted on a Windows 8.1 device and holds about 500 GB of data. Before you buy the Tablet, I had accesses files by using an older MacBook with no problems. Is it possible to access the hard disk on the Windows 8 RT Tablet without initialization (which I guess would involve having to temporarily move all data to another device and then reload on the external hard drive reset)?

    Hello

     
    Thank you for your response. The information that you have provided are appreciated.

    As you say it has compatibility issue, the latest drivers for the device must be installed to have all the features.

     
    Try to install all the updates of Windows including the optional updates, after having connected the external hard drive with the Tablet and check if it helps. You can check the link below to install Windows updates.

  • How to get the Favorites after resetting my computer? firefox saved on the external hard drive folder

    I had to reset my computer because I downloaded a sort of hidden adware that downloads new adware permanently, which makes my computer unusable. Adware ill-conceived, lol.

    I saved the folder of firefox mozilla whole folder of files (x 86) programs on an external hard drive. I thought that if I just copied this file on the computer, my favorites would be sympathetic to it. all the Favorites are gone.

    bookmarks are not stored in the folder of firefox? is it possible to recover? It's worth years of bookmarks I need for work.

    any help is greatly appreciated, thank you. I tried the suggestions that others had offered for similar problems.

    Your Firefox personal data is not stored in the Firefox program folder, but are stored in the Firefox profile folder that is located in the AppData\Roaming\ folder.

    • C:\Users\ < user > < profile > \AppData\Roaming\Mozilla\Firefox\Profiles\.

    You can use this button to go to the current Firefox profile folder:

    If you do not save this profile folder then your bookmarks and other personal data is lost.

  • How to reset the password forgotten on external HARD drive

    Hello

    I forgot the password of my external hard drive.
    How can I reset this?

    It has all my photos out there I want to come back.

    The external HARD drive comes with software that the password. Have you used this software?

    I m not very well what HARD drive you have exactly, but in the case of the password disk HARD unknown could be deleted, so I guess that by using such software.

    But I'm afraid, this is not possible and if yes, then secure files could serve more than m.

    I say it in a different way: password protection would be useless if you can remove any unknown or forgotten password. Don't you think?

  • Seagate external hard drive / / no display

    Recently I bought a Portable Seagate 2 TB external hard drive for my MacBook Air. I put all my movies, music, ext documents on my hard drive with my important homework. The reason why I did was reset my mac, then return all my old documents, photos ext, back to their place of origin. I have managed to do and frees a lot of space. A few days after my MacBook fell asleep with a connected external hard drive and now the hard drive is no longer present on the desktop or in finder. I am able to find in my "disk utility" , but for some reason, it shows the hard drive passed out faded gray and full? I tried to hook up with different cables and on the various devices as well. Also sang the first aid option in "disk utility" with no other results. I have contacted apple support and found out it was the external hard drive with the problem, so they couldn't help me. They then redirected me to Seagate Support, and I had already tried the methods they gave me (see list above). I was wondering if anyone here on communities of Apple has experienced the same problem as me, it would be that much appreciated advice you may have. I have important files that I need to recover.

    Help, please!

    Had a similar problem with external hard drive WD also on model MBA early 2015. Found if I disconnect the external hard drive restart MBA and then reconnect the external hard drive it was working normally again.

    Another thing I tried was still unplug HD plugin MBA on sector and re - a SMC.

  • Problem of macOS / external hard drive

    My external hard drive (Seagate Portable) went wonky after update of my MacBook Pro for macOS Sierra.

    I did some research and I've followed all the advice - nothing helped.

    ・It is not in the Finder.

    ・It is listed in "Disk utility", but I can't do anything with him - like mounting the drive.

    ・ "Disk utility", says that the Seagate drive is completely full - but I know for sure that's not true - it was about a quarter full and has only a few months.

    ・i reset the PRAM & SMC on Mac

    Try to update the Paragon NTFS driver. You can find the updated version on the Seagate support site at:

  • Backup to one external hard drive to another

    Hoping someone can explain to me how to copy a backup of one hard external to another.  I managed to make a complete backup of the old iMac, my sister just before he died.  The backup is located on a WD My Passport for Mac and I would like to copy the backup to another external hard drive, maintaining the original on My Passport for Mac, just to keep safe in the event of failure of one of the external drives.  This backup contains the only copy of hundreds of pictures.  Any suggestion would be appreciated.  Thank you.

    If it's a Time Machine backup, click here for more information.

    If there is a bootable clone, rerun the utility of cloning, but with the new source and destination drives.

  • Of failure, white screen MacBook Pro HARD drive try to boot from the external HARD drive

    Hello

    I have a 2008 Macbook Pro which is having some problems, I was able to fix them, but eventually the hard drive failed. I know that because at startup until it would have a white screen Uni (no logo) and you can hear a clicking on in the lower left corner. I thought initially it was a memory problem, but after opening and verification of memory, it's clearly the hard drive.

    I solved this problem temporarily (until I can replace the HARD disk) by installing El captain on an external HARD disc and start from that. Here's the twist, I couldn't he can begin to El captain, I tried CMD + R, CMD + OPT + R, CMD + OPT + R + P and now shift. Everything that's happened would be that clicks would cease to release the keys.

    I left the macbook on while I'm at work, when I got home it was on the screen to connect the external HARD drive.

    I accidentally closed the macbook yesterday and again once when I tried to log on, I could not and I left it on a white screen while I was sleeping. There is a possibility that he may have launched from the HARD drive when I get home, but if not, is there something that escapes me to force do this?

    See you soon

    Usually start up to a blank screen without the Apple Logo, may report one of the following:

    • Hardware failure
    • Boot drive is not recognized as valid and updated updated
    • OS X essential software is missing, hurt moved or renamed or corrupt
    • A firmware update is necessary

    No matter who, in order to boot from an external drive "bootable", you would normally hold down the Option key until you get a screen that offers a number of devices to try to boot from.

    Alternatively, you can try holding down the C key to try to boot from the external drive.

    If none of these startup options work, then the bootable disc or the USB port on your MacBook Pro can be the question.

    Since you have a Mac pre-2013, if you hold down the D key while booting, the built-in Apple Hardware Test should start up.  This can help to identify hardware problems.

  • Move photos iPad on an external hard drive

    I have about 4000 + photos on iPad Pro of vacation, I downloaded from a SD card using an adapter. The photos are distributed among the 15 albums or more. I want to get the end these photos on an external hard drive. Currently they are all saved in my pictures from iCloud, but my only option with iCloud Photos is to download these photos individually, and I don't have the time to download 4000 + photos individually.

    I would import each album into my Mac Photos app, but my Photos Mac app refuses to acknowledge one of the albums. No amount of reset or change the USB port or reload all fixes the problem.

    I tried to use iTunes to get the pictures, but they are not found.

    Ideally I would like to batch download all about iCloud Photos, but there seems not to be this option.

    All this seems unnecessarily complicated. How can I get photos from my iPad on my hard drive? There should be a way to simply drag and drop, in my opinion.

    Thank you ~.

  • To access the other account via external hard drive

    MacBook Pro (13 inch, early 2011)

    V.10.11.6 El Capitan (15G 31)

    To summarize what I've lived, I got a kernel panic, by connecting to any account. So I tried to fix it by zapping the PRAM and NVRAM, tried the reset SMC, and both did not work. So I installed El Capitan on my external hard drive and it works, I just need to access the other account on the Mac to recover photos and then do a clean set install.

    The problem is that I do not know how to access the other account on the mac like I did not move any info from another acc to my external hard drive. Is it possible to do more than to reconfigure my HD post and return to the new installation procedure? Or I'm able to get pictures on the other account with the photo software?

    Open the drive containing, then the folder users, your record of departure, and photos. If you encounter a file that you don't have access permission, either drag it to the office supply your administrator password, or select the entire disk, choose get the information in the file menu and set to ignore permissions or ownership.

  • External hard drive WD Element

    I had this WD element external hard drive for over a year now, which can connect to any PC or Apple, but for some reason that I myself brought recently the MacBook Pro and now my external hard drive WD Element only want work

    When she wants to. I am struggling to get it working 100% every time. I know that my hard drive works cos I have connected to my old Mac G3 and I see the hard drive, but not on my MacBook Pro. What can I do to make it work every time?

    You can try to perform a SMC reset. Reset the management system (SCM) controller on your Mac - Apple Support. (The previous sentence is a clickable link)

    Drives external WD hard seem to get more complaints than any other player. They use a chipset of decorum and cheap components and seem to be more prone to error than the other speakers. If the gives still drive troubles you, you pourriez be able to remove the drive from its case and put it in another forum. I like the housings of OWC . I say maybe because I've seen also some WD external drives that do not use the standard SATA drives.
