Backup hard drive to an external hard drive

My external hard drive is 250 gigs and my laptop hard drive is about 30 gigs with about 5 gigs of free what i was trying to do is backup the whole c drive to the external drive and delete some programs to give my computer more free space.... so when i tried to backup the internal hard drive it only backed up 4 gigs then said there was and error with something involving media so i repeated this process 2 more times and it did the same thing and stopped at exactly the same amount of data backed up. could there possibly be partitions on my external hard drive that i dont know about? and if so how could i fix it and if now how can i fix it...thanks for your time

Re: backup hard drive to an external hard drive

As Pegleggedous said, the FAT32 File System only allows files that are 4GB or smaller.

Another solution to your problem is to convert your hard drive to NTFS.

Please note that you will only be able to use your hard drive with Windows 2000 & later if you convert your hard drive to NTFS. Instructions on how to convert your hard drive to NTFS are available on Microsoft's Website.

Have a nice day,

Re: backup hard drive to an external hard drive

"what the error actually says is, you have either run out of space, or the backup file (.bkf) is too large for this disk. note: if the disk is formatted with FAT32, the maximum possible size for the backup file is limited to 4 gigs."

That error means that the FAT32 file system only allows 4GB files or smaller to be transfered. The chance that the backup file (.bkf) is larger than 4GB suggests that this file is causing your problems. You could try manually copying around that file (selecting all files from that folder except the large one) and see if that works.

Usually you will get many errors copying a drive directly as system files will be inaccessible and whatnot. Your best bet is to limit your copying to "C:\Program Files\" and "C:\Documents and Settings\", assuming you have Windows.

I backed up data w/ WD Passport External Hard Drive, and when finished my computer's free hard drive space went from 115 gigs to 11. What happened, and how can I fix this?

What could have happened is that you backed up your drive onto itself. Check your external and see if it's still empty. If you named the backup, search for that name and remove it. If not, retrace your steps right until the beginning of the backup and see what location the software stores the file then remove it.
Worst case scenario you can always use the windows restore utility and go back 1 day before you ran the backup.
Good Luck

Laptop Won't Recognize External HD

You can try opening the device manager in Window XP and uninstall the external hard disk (make sure you show unplugged devices).
Then replug the drive again, and it should reinstall the drivers.

It assumes that the drive C is the drive you booted from or the "root" drive. You must make it something other than "C". Try putting in a camera card, hooking up an external drive or other device that the computer makes drive "C" THEN hook up your passport. It will be "D" or "G" or something other than "C" and it will work.

221 GB Free on MyBook - Error states not enough space for backup

It may be due to the file system.  If formated as FAT32 files larger than 4gb may not transfer.  Try reformatting as NTFS to fix the problem.
