  • Satellite A200-1If - drive external HARD after a while is "unknown device".

    Hello!

    I have such a problem: I work with my external case alu Toshiba 3.5 HDD 500 GB and after awhile of copy of the files in the laptop it disappears and appears this luckily device recognized.
    Can it be caused by not enough power in the USB port?

    THX for any help or the workaround

    Hello

    Yes, this may be caused by the fact, there is not enough power provided by the USB port. first of all, note that external USB hard drives 3.5 inches are generally designed to be used with systems of office due to their higher power needs (this is also the reason that many need an external power supply of their own). my suggestion would be to buy a 2.5 inch drive external hard USB is designed to be used with laptops. Another reason that the hard drive may disappear when copying files, is that there may be a problem with the connection of the USB cable between the laptop and the external HARD drive. I suggest to check that both ends are connected properly and not put any pressure on the cables and keep them stable.

    I hope this helps you with your question

  • Drive external HARD encrypted in ExFat?

    Hello

    I have a new drive external HARD I need to use on a Mac and a PC. I need to access the same files (data analytics), so I don't want to make 2 partitions and have duplicate files. What I've read, it seems that ExFat is the best option for this (they are large files, so that the FAT will not work). My work, however, requires external hard drives to encrypt. When I tried to put it on my MacBook Pro (El Capitan), however, I received an error.

    My question is this: is there a way to meet all three of these criteria?

    (1) disk encrypted

    (2) read/write on a mac

    (3) read/write, the same files on a PC

    I have a separate HARD disk for Time Machine, I use an airport. This disc will have to travel with me.

    Thanks in advance!

    If you were able to encrypt it using the built-in OS x software, Windows would not be able to decipher. If you use a Windows build-in encryption software, OS X would not be able to decipher.

    You have to find a 3rd party package that works on BOTH OS X and Windows, which can encrypt and decrypt on both platforms.

    In the past, I would have done TruCrypt, however, he was abandoned by unknown original authors, but there have been a few replacements based on the original source of TruCrypt.  Try googling 'TruCrypt Alternatives' and you might find something where they support the OS X and Windows.

    Otherwise, you will need to find another cross platform encryption package.

  • Connection drive external hard am.

    Hello world
    I wonder if it is possible to connect the drive external hard am to z3?
    In the light of others do it on the other android device. Got an otg cable, plugged my HDD but the phone is not supported it or I'm doing something wrong.

    Any help with this would be appreciated.

    Yes, you can check what file system that is used if you connect to a PC, right-click on the drive in the Solution Explorer and select Properties.

    It is possible to convert NTFS to FAT without deleting all data, but I do it without the first run a backup in case something goes wrong. And if you have files bigger than 4 GB it will be problems with these as FAT32 does not support that. exFAT supports, but I didn't know of any tool that can convert NTFS to exFAT without wiping the drive.

  • Cannot access the files from the internal hard drive that has been converted to drive external hard after the motherboard is dead

    I can't access the files from an internal hard drive that has been converted to drive external hard after the motherboard is dead. I think that my files are still there, as shown in the volume of the player volume ~ 500 gb which is almost completely full. But I can't access most files, including documents and settings. When I took 'ownership' of the folder, I could open the TI but then it showed everything that was in my documents and settings on the computer file I used to open it, not the documents of the car.

    Uhm... I think the issue here is a misunderstanding of what you watch.

    If you want to access your files from the old hard drive - you need to look in the right place.  If the old system was "Windows 7", "Documents and Settings" is the * wrong * place to look and "Users" would be the place to go.

    You * will * take ownership and change permissions on ALL (you want to propagate to all subfolders/files when do - to save time) in order to get them properly.

    New-->: Windows Vista/7 would have your files located in the directory 'Users' of the root of the drive - and then under your username.

    • \USERS\\Desktop\
    • \USERS\\Downloads\
    • \USERS\\Favorites\
    • \USERS\\Documents\
    • \USERS\\Music\
    • \USERS\\Pictures\
    • \USERS\\Videos\

    ... etc...

    Documents and settings to WIndows Vista/Windows 7 is a symbolic link and would lead to what you see if you tried to use it.

  • Drive external HARD Toshiba PX1267E - 1 32 cannot be properly detected/installed

    Hi everyone, I need help.

    I have a Toshiba PX1267E - 1 32 external hard drive that I used on my PC under Windows XP. Yesterday, I bought a new laptop with Windows 7. When I plug the HD via USB, it is said that it cannot be properly detected/installed.
    It does not appear in 'my computer' and I really need to transfer a lot of data on my new laptop.

    I can do to make it work?

    Are there drivers for Windows 7? I can't find my original CD

    Any help is very appreciated. Thank you

    Hello

    Looks like a HARD drive contains a preinstalled software that is not compatible with Win 7.
    I'm not sure if this will help but try this:

    Connect your HDD to the other no Win 7 PC
    Select the CD drive with your browser (password)
    Run the ONSPCLCK.exe (or another exe file which controls and password.)
    Select 'Options '.
    Select "Disable security password"
    Enter your current password
    Unplug the HARD drive
    Connect the HARD drive to laptop with Win 7 OS.

    Hello

    I guess that this external hard drive is a USB - stick. Have you tried to connect it to another PC? If this isn't the case, so I propose to do this and check if your drive is working correctly.

    The best state test would be to check this with a PC which has Vista.

  • Satellite A100-216: can I move Windows.old for drive external HARD

    Hello

    I got my satellite A100-216 almost 12 months, (and I'm pleassed with it, incidentally), and bought with XP, but she has the option (taken) to get the upgrade to Vista Home Premium.

    I have finally plucked courage to Vista and have a question.

    In the book, it says that the hard drive will be completely erased, and all must be safeguarded. OK - did this.
    It lights up during loading to say that only a full upgrade is possible and that the old windows will be stored in a folder called "Windows.old" even if the operating system will be unusable.
    There seemed no option but to agree with what is happening and lo and here is the record + Windows.old + is here, and it's * Gb * 6 in size!

    After saving everything, can I really keep this large amount of things on my HARD drive. I can move it on my external hard drive?

    The capacity of the HARD drive, (nominally 100 GB) but showing 93Gb shows 24,6 now used by Vista without other programs or drivers installed.

    If I remove this 6 GB, I'll have a more reasonable 75 GB to play with.

    The other option would have been to start on an OEM XP disk, opt for delete and re-create a primary partition and load Vista from there after the format. Would it be: r: work and B: use less space.

    If the 6 GB file is all that it would save, I'll just save it on my external HARD drive.

    Thanks :)

    Hi Dave,.

    The Windows.old folder is a backup of your files/folders/settings of your XP system etc.

    It is automatically created during the process of update for Vista and is designed as a quick way to return to the earlier version of the operating system if you need to do. \obviously its value will decrease over time, once you start using Vista, because different files will become obsolete with the use.

    The normal procedure is to remove these backup files "shadow", once you are happy that Vista is not working properly and there is an option to do it for you in the utiliy Vista disk cleanup.

  • try to save the contents of the hard drive for drive external hard error0.80070020. Spike

    Try to back up the hard drive internal to an external hard drive, Windows Vista. Error message 0.80070020 receipt, no return to the top. Spike

    Hello

    1. don't you make changes on the computer before the show?
    2. What is the accurate and complete error message that appears on the computer?
    3. How do you back up the hard drive?
    4. are you using Windows backup and restore, or you are using a third-party backup program?
    5. do you use windows backup and restore?

    Method 1:
    Clean boot the computer, and then try to save the contents of the hard drive and check:
    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7
    http://support.Microsoft.com/kb/929135
    Note: After a repair, be sure to set the computer to start as usual as mentioned in step 7 in the Knowledge Base article.

    Method 2:
    You can also try to disable antivirus and then try to backup. Follow the steps in this link: http://windows.microsoft.com/en-US/windows-vista/Disable-antivirus-software

    Important: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

    Method 3:
    If the problem persists you can try running the disk check and check hard disk errors:
    http://Windows.Microsoft.com/en-us/Windows7/check-a-drive-for-errors
    Note: When you run the disk check, there is a risk of data loss, you can take a backup of the data on the drive before running the disk check

    How to get Vista recovery Media to back to factory settings.

    There is no Vista free download legal available.

    Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

    Normally, they do this for a cost of $ small.

    Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
    A good Vista DVD contains all versions of Vista.
    The product key determines which version of Vista is installed.

    There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

    If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

  • Cannot see all files on external drives (external HARD drive / flashdrives)

    I do not see any folder on my external hard drive, I know that these files exist because it still shows how the same amount of space remaining left on this drive. Is the same for all flashdrives I plug it into my laptop

    Edit * directories to the folders still exist, I can access when I type in my address bar, but I can't see the icon to click on it.

       

    Hello

    Windows 7 sometimes has trouble seeing external drives. Found one potential than me and other solution is to download and install the freeware Aomei Partition Assistant application, download it here: http://download.cnet.com/AOMEI-Partition-Assistant-Standard-Edition/3000-18512_4-75118871.html?tag=mncol;1 (only use the Direct download link).

    Once installed, go to the readers in question and one both select and select Properties. It is her, no formatting or partitioning required. Just select the drive is often enough to get Windows 7 to recognize.

    Post your results here and let me know how you fare.

    Kind regards
