I appreciate your help in advance.
I have been running an external Seagate HD, capacity 500 GB with my most important information/files/documents, etc. on it and running back ups through Windows with no problem.
Foreseeing future need for more capacity and the desire to go paperless, I purchased an external Seagate 4TB hard drive and moved all files from the 500GB drive to the 4TB drive, then attempting to run a back up on that. The files to backup to the 4TB drive were C:/ , D:/ , and H:/ (the 500GB drive). I have run multiple attempts to backup to the TB drive with multiple back up failures.
I clicked for more information on the backup failure (from the error window), and got the message "The request could not be performed because of an I/O device error". Crap!
I researched this and came upon the following link: http://support.microsoft.com/kb/952272
The link suggested I run Chkdisk on the drives I am interested in. After a combined total of about 12 hours, both Chkdisks on the two different HDs came up with no errors.
The next step the website suggested was,
"Advanced Troubleshooting
This section includes an advanced troubleshooting method to try if the steps in the "Resolution” section do not work. This method is intended for advanced users only.
The backup may still fail, and you may receive the following error code:
0x8007045D
These conditions may occur after you run chkdsk on the backup source and on the destination locations. In this case, you may be experiencing a rare issue where backup fails, and you receive the 0x8007045D error, at the very end of the backup process when it is around 99% complete. This rare issue can occur when the backup fails because the last cluster on the volume has gone bad. You should be aware that chkdsk.exe does not handle this situation.
WORKAROUND
To work around this issue in which the last cluster has gone bad, you can shrink or extend the volume by several megabytes to move the last cluster of the volume to a different area. Then, you can run chkdsk again.
For more information about how to expand or extend the volume by several megabytes, visit the following Microsoft Web site:
http://technet.micro...y/cc731894.aspx
After the chkdsk process is complete, perform the backup operation again."
I chose not to continue with the Advanced Troubleshooting advice or the workaround. I never received error code 0x8007045D, and I was hesitant to extend the volume size.
I looked around further and came upon this link: http://social.micros...rouble-shooting
I followed the first step, which was "Most of the backup and restore failures are caused by server missing updates, network connection issue or hard disk failure. If you get into any of the backup or restore issues, start with the following steps:
1. Make sure your Windows Home Server is up to date.
a) Open the console and click Settings->General.
b) Click the Update Now button in the Windows Update section to install the latest update."
However, I did not understand the next steps after that so I did not continue.
I searched further and came upon the suggestion that the Antivirus programs installed on the computer may be "1. http://support.micro...spx/kb/973455/. If you add a reparse point or a child of a reparse point to a library.
2. Antivirus/Antimalware reporting some bad files and holding locks for those files. Backup fails when it tries to backup these files. For this, please remove the bad files reported by the Antivirus/Antimalware and rerun backup.
What you call junction points are likely issue 1 identified above.

At this point, I was fed up with fooling with it and decided to jump onto this forum. If the suggestion about the Antivirus turns out to be my problem, I could have disabled it then run another Chkdisk, but if it turns out to be a dead end, I would still be about 12+ hours into another Chkdsk with no solution. I was hoping the "Geeks" on the forum would have another suggestion besides running a Chkdsk. I am thinking if both drives turned up out of the scan as good, then there must be another problem.
In addition, I am thinking the problem might lie in the new 4TB drive, because when the same files were on the 500GB drive, there were no problems backing up. However, the drive is brand new and I am hopeful it is not bad
The only thing I have done with it was move all files from the 500GB drive to this one, then tried to run a backup, which failed...I am also hoping in the process of troubleshooting the drive, I don't lose all the stuff that I just moved to the big drive, since due to my eccentricity, I deleted the backup I had made when the info was on the 500GB drive, to save computer space before running the new backup with the info being moved onto the 4TB drive. I don't think I have room on my computer to move the files from the 4TB drive as a "holding pattern".
Thanks once again for your help!
