Using R&R 2010 Free Advanced! with W7 Pro 64-bit. Checked integrity of a archive just finished, got about 7 or 8 integrity errors till it aborted on its own. Read another similiar thread and did a ChkDsk, no errors but 50 parsed records found. Ran CHKDSK on the external USB drive, nothing at all found. Did another archive it abort again with eight integrity errors. The error listed as from Hard Disk Manager, Error Code 0x10025. Both times on the archive it excluded data from two files from the bitmap, pagefile.sys and hiberfil.sys. What about antivirus software running in the background??
