I set up my Idea Centre K330B to schedule complete system backups to an external HDD once a week. This worked fine for three months, then about a month ago a scheduled backup failed due to "device error encountered with either the source or the destination (0x8078012D)". It also gave "Additional information: The request could not be performed because of an I/O device error. (0x8007045D)"
I ran chkdsk/r on both the backup drive ( E: ) and the system drive ( C: ) and no problems were found. The backup drive has plenty of available space. I tried the backup to a freshly NTFS-formated external drive. I tried the backup with my BitDefender 2012 Anti-virus disabled. I tried the backup after booting in safe mode. Nothing works.
If I specify to backup only C: and not the reserved partition the backup completes with no problems.
I get the same error condition whether I perform the backup with Windows or the Lenovo backup software.
Is it possible I have a disk corruption on the reserve partition that is not found and repaired by the chkdsk/r C: operation?
I'm thinking about saving all important user files and rebooting to the factory settings, but if the reserver partition is damaged I might end up with a dead 4-month-old PC.
I would greatly appreciate any help or advice as to how to get these backups going again.

I just tried running the Lenovo Hard Drive Quick Test both in normal mode and in safe mode. Both times it indicated a failed read test on the HDD. The last two tests also failed. I forget what those tests were called.
I am really beginning to think I have a bad HDD and the problem just happens to be in the reserved partition where my factory system software resides.

I am having this same problem.
Were you ever able to resolve it? I was thinking of saving individual files and doing a factory Recovery, but like you said, I am very afraid it will kill my computer. (Mine is an IdeaCentre B500)
