Sounds like they are encrypted with your old key. I don't expect you can get into them without setting up the old key in your new system.

One or more of the hints below will probably sort out most USB problems with most USB portable / external hard drives and OTHER devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems (mac/ Linux) similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especially true if you move a HUB to another port
6. For FLASH DRIVES you should ensure that the device is set for "quick removal" using the drive control panel properties or use the USB "Safely Remove Hardware" option. If you dont do this there is a very strong chance that any files you transfer may not be there when you plug into another computer.

If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further

USB flash drives can fail for no apparent reason.
Sandisk Cruzers are especially bad for this.

USB hard drives should be treated with extreme care.
This is a real hard drive ! and knocks and bumps can quite literally kill them.

It is possible to remove drives from the enclosures in most cases and connect directly inside a PC to fully check it.
You should also do this to cheack the drives connections are not bad inside the enclosure

Note that if you hear a drive clicking or pinging this could be the worst thing you would hear.
Known as "The Click Of Death"

If none of the above steps help look at updating the drivers from the manufacturers web site in the support section.

How to remove write protection from sony hd-e1


PC & MAC use different file systems.
It sounds like your hard disk is formatted as NTFS. NTFS will allow a MAC to read from the disk, but not write to it. You need to re-format it using FAT32 (if your MAC is older) or exFAT(if your MAC is fairly new)..
FAT32 will allow a maximum partition size of 2TB(when formatted from a MAC) and a maximum single file size of 4GB.
exFAT will allow pretty much any file size.
NB:Formatting a hard drive DELETES ALL FILES on the hard drive, so backup whatever is important before you re-format it.
1. Open Applications > Utilities
2. Choose you hard drive from the list on the left
3. Choose the "Erase" tab and choose your desired format (FAT32/exFAT)
4. Type in a new name..Click "Erase"

Remove write protection from my LG External HDD HXE4 3.0 500GB


Using an external hard drive is a convenient way to transport files from one computer to another or share files with a co-worker or friend.
Activating copy protection, otherwise known as write protection, on the files that you place on the external hard drive is a good idea, as it will prevent that data from being altered inadvertently when connected to another machine.
Remove copy protection from your files when the external drive unit is again attached to a trusted PC and you wish to change the structure of the files.

Connect the external drive to your computer system.
Right-click "Start" and then click "Explore."

Click the external drive on the list of available devices.
Right-click on the copy protected files that you wish to unprotect status and click "Properties."
Uncheck "Read-only."
Close the Explorer menu and proceed to edit your files as desired.

Hi, I cannot print a pdf file or that kind of attachment. Only Word can print. Adobe error shows up and want to shut down the program for protection. I never had the problem before. Just started.


Is it a file that you created in pdf format, or is it one that you have had emailed or attempting to open from another source? Some pdf files have protection put on them by the file originator to avoid the file being changed/printed. Here are some tips to try to get them to print for you.
  1. Open your computer's Internet browser.

  2. 2

    Type www.a-pdf.com/security/a-pdf-rr.exe in the browser's URL box to access the PDF restriction converter "A-PDF Restrictions Remover."

  3. 3

    Press the "Enter" or "Return" key. Your Internet browser will access the site's PDF converter file. A dialog box will appear on your screen--"Opening a-pdf-rr.exe."

  4. 4

    Click "Open" or "Run" to download and set up the program directly. Click "Save" or "Save As" to save the program's setup file on your computer for running later--use this option if you using a slow connection like dial-up. The program will download and set up on your computer if you selected the "Open" or "Run" option.

    If saving the file to your computer, navigate to the directory where you want to save the file to. Select the "Desktop" if you have a hard time locating downloaded files on your system.

    You do not have to access the A-PDF Restrictions Remover website again once the file starts downloading or saving to your computer.

  5. 5

    Double click on the "a-pdf-rr.exe" icon to open the program, if you selected the "Save" or "Save As" option.

  6. 6

    Click "Run" when prompted with the "Open File -- Security Warning."

  7. 7

    Click "Next." Click on the circle by the wording "I accept the agreement." Click "Next."

  8. 8

    Select the directory where you want to save the "A-PDF Restrictions Remover" file. The default is your "C:\Program Files\A-PDF Restrictions Remover" folder. Click "Next."

  9. 9

    Click "Next," "Install" and then "Finish." A-PDF Restrictions Remover will start automatically.

  10. 10

    Navigate to the directory where the protected PDF file is located.

  11. 11

    Right-click on the PDF file name. Select "Remove Restrict & Save As."

  12. 12

    Select a location to save the converted PDF file to. Click "Save." If you want to change the PDF file's name, enter a new name in the box next to the wording "File name." The protected PDF is now converted to a unprotected one.

  13. 13

    Double-click on the converted file to open it.

  14. 14

    Select "File," "Print" and then "OK" to print the unprotected, converted PDF file.

  15. Printing a Protected PDF By Taking a "Screen Shot"
  16. 1

    Open the protected PDF file2

  17. Press the "Alt" and "PrtScrn" keys together. The PrtScrn key is located on the upper right-hand side of your keyboard, if using a desktop computer keyboard. If using a laptop, the PrtScrn key is located above the "F10" function key.


  18. 3

    Open your computer's word processing program by clicking on the program's icon on your system's "Desktop" or from the "All Programs" menu.

  19. 4

    Press "CTRL" and "V" keys together to paste the screenshot into a blank document.

    If using a Mac, click "Edit," "Paste" from the main toolbar at the top of your word processing program.

  20. 5

    Click "File," "Print" and then "OK" to print the PDF screenshot. If the protected PDF file contains more than one page, press the "PgDn" key and repeat steps 2 through 5.
