Backup Win7

[tourman]

I am using an Iomega 500 GB eGo External Hard Drive to back up my system. I am getting an I/O Error before the backup is complete. I have checked my device and it is operating fine. I just installed (full) Win 7 Home Premium Edition.

Is this I/O near the end of the backup? Is the I/O error on your OS (source) drive or is it the external Iomega drive?

I recall reading a potential fix for these strange I/O errors. Is this a "system image" or a regular "file backup"?

 

[tourman]

Yes, the error occurs at about 75%, system image!

What is the specific 0x........ error code?

Or, check the event log:

Control Panel > Administrative Tools > Event viewer.

Once in Event Viewer, open > Applications and Service logs, >Microsoft, >Windows, >Backup. Take a look at those events and see what pops up.

Thanks for all your help Jim:
Here is the error (0x8007045d)

This Microsoft article seems to address this Error message when you try to perform a full backup on a Windows Vista-based computer: "The request could not be performed because of an I/O device error"

kado897: Not using window vista

I suspect that it would apply to Win 7 as well.

I/o Error

I ran the chkdsk as instructed and the process stalls at stage 4 of 5? LOL this is getting ridiculous. The operating light on my external hard drive goes out when I do this chkdsk procedure.

It sounds like you have a problem with your drive then. Download HD Tune and run it against the disk and see what we get.HD Tune website

I've read something about how to fix regular FILE backup which I think applies here. However, it makes NO sense why the end of your partition would be accessed (link from kado) as their likely aren't any files there.

Shrink your partition (source to start with) and see if those bad clusters on the source are what's causing this.

kado897: I ran HD tune up. My Ext. Drive is good! Hmm.

JimShrink your partition (source to start with) and see if those bad clusters on the source are what's causing this.) You just scrambled my brain there. LOL... I dont think my wife would want my partition shrunk! BAHAHAHA. I would not no the first step in performing this procedure.

Thks

OK that's good. Lets see what others think.

There's probably a shrink partition tutorial on sevenforums.....

It's quite simple once you see the screen images/instructions.

 

[tourman]

What would shrinking the partitions accomplish Jim? Other than to make more room on the HD?? I have 500 GB on this thing, I don't think it takes more than that to do an image backup?

Your problem is not really similar to this one, but worth a try.

Backup and Restore Error: The backup failed. New bad clusters were found on the source volume. These clusters were not backed up. (0x8078007D)

The aforementioned website has a ton of really good solutions.
