Question about Western Digital 500GB My Book World Edition 500 GB Hard Drive

2 Answers

Works fine except it won't store ISO files

The External Works Great except this.
I have some ISO files on my computer and when i try to copy (or cut) them from my Internal HD to my External, i get this following message:

If picture doesn't show i have a link here

This applies to ALL ISO files. DVD Rips. Game Rips, or files that happened to be stored in an ISO.
it for some reason works for other image files like .uif but won't for ISO.
All other files copy over but this.
I talked to many people (computer nerds as people would call them) and they all had no clue why it would do this.
If anyone can help me that would be good. I can free up to 20+ GB by being able to move them over.

    My Internal HD's are Formatted as NTFS, my External was Auto Formatted as FAT32. I was debating on if i should have reformatted it and made it NTFS, but i didn't and i now think i should.

    I just tried it with Another ISO from a PS Program and it did work. It was only 142MB. Now i need to find a way to move them over. I DON'T want to make them multiple parts cause then (knowing my luck) the ISO won't work correctly then.

Well from what i have observed from the images is that you are using the FAT32 file system and FAT32 is designed in such a way that the maximum allowed file size (size of a single file) on a FAT32 based file system is at most 4 G and whenever u try to copy a file of size more than 4 G, you get a "Disk Full" error. This is pretty normal.
So, it would be better that the next time you think of re-installing windows, make sure you format the drive(s) using the NTFS file system so that you wont face the error again.

Workaround: You can split them up into parts of an archive of 100 MB size so that they can be copied onto the external drive without any problems. (use WinRAR)

Try burning an iso image file instead from the program, then you can use the built in mac software to burn that disk image file to a disc. Sometimes in video editing there is a problem with the process of compiling the video to a disk. Try a simple very short project with a dvd-rw (reusable) disc to see if it still gives the error.

Windows 7 instaiiation disc

When you purchase Windows 7 from Microsoft Store, you have the option to download an ISO file or compressed files.

The Windows 7 USB/DVD Download tool allows you to create a copy of your Windows 7 ISO file on a USB flash drive or a DVD.

To create a bootable DVD or USB flash drive, download the ISO file and then run the Windows 7 USB/DVD Download tool.

Once this is done, you can install Windows 7 directly from the USB flash drive or DVD.

Hope it helps

I am an english teacher and purchased last year a cd from cambridge university press. The cd still works but it is starting to fail. I have tried several softwares to make a virtual image copy but when I...

By the error you are describing, at first glance, it does not seem to be the ISO (virtual image copy) file that is faulty but the emulator itself...
Uninstall all emulators you have and install DaemonTools Lite Restart your computer after installation. On your SystemTray (left to the clock) it should appear the DaemonTools Logo, click it to mount your ISO. Test it
If it doesn't work, try another copy program. I find ImgBurn a very powerful opensource tool for this kind of operations.
Finally, if it still does not work, i must remind you that you can copy the contents of the CD directly to your pc and run it from there. If the cd has errors (scratches or such) the optical driver will try to correct them and in a cd copy (an ISO is just a copy into a file that should be emulated like a disk itself) the errors will be copied as well.
If you copy the cd into the computer, the computer will try to fix the errors alongside the optical drive itself. If the cd is still working this procedure should save the contents...
Once you get the contents from the disk to your pc, you can make an ISO directly from the files on your computer, or copy them to a new cd... Remember, copying a cd is not illegal if you have the original and is for backup purposes only.
Hope this helps, if not contact me.

My computer recognizes the external drive but denies me access to it

There are a couple of different things we could try BUT the safest and smartest way to access it is with a Live Linux boot up disc like Ubuntu.

It's free, just download a copy, burn the ISO, boot to it, and then try to access the external drive.

Copy all the important stuff off the drive, format the external, and then copy everything back. Don't delete your files until you know for sure the drive is working correctly.

If you have any questions about what I wrote, just write me ;)

Access is denied on picture and video clip file.

I had the same problem before. Unfortenatly this has to do with owner permissions set on on your old device and not recognising or accepting this permissions on the new.
If you still have your old device working then change the permissions for all files to "full control" for "everyone" and then copy. this is will solve the issue.

Does not boot up

Probably a virus, or your windows folder got corrupted. Try to use Knoppix (A linux distrobution that boots from a CD) to get all your data onto a pen drive or external hard drive. Download the Knoppix ISO at and burn it onto a CD or DVD using MagicISO ( Insert the CD, and you should see the boot screen. Open the file manager, and copy all the files you want to keep from your hard drive to a pen drive or external hard drive. Then, reinstall Windows using a recovery CD (one might have come with your computer). Copy the files back

create a new folder in your hard-disk and first try to copy 1-2 files from the external hard-drive to the new folder (copy any data/work/images you have stored/created not any files of windows folder or root of c: drive)

if the above copy works then copy back all except the c: root and these folders - Windows folder, Document & settings, Program Files

Using the 160GB passportHard drive

are there any errors that popped up while copying the music files? if not, then it probably works fine. the files are now stored on the harddrive.
if you want to safely unplug and carry the HD over to another computer, you can., the files should be accessible... that's all a harddive does.
