Backup error: 0x8007001b

Each time I do a backup on DVD, it aborts, says "could not find the sector requested," and lists this error number: 0x8007001b.

 

hmm try the work-around mate:

1) Delete ALL of the unwanted backup file on "D" EXCEPT the Recovery
folder which was put their by the manufacture (HP in my case). These
are typically D:\<PC Name>\Backup Set<Date and Time>\Backup
Files\Backup files.zip These are in the Catalog and Backup Set
folders. Use Windows Explorer set to view full path and file
extensions to delete these files. This takes some time and effort
because the Recycle Bin on "D" must be emptied several times. Keep
deleting until the only thing on "D" is the manufacture RECOVERY
Folder, empty Recycle Bin, and an empty INI folder. The "D" drive
should now contain only about 500 Mb.

2) Open Visa Back-UP and set the Back-Up Drive to the "D" Drive. Set
the Back-Up files which you need to back-up (e.g. Documents, etc.)
Caution if you have Picture, or a large amount of other data (>2 Gb) DO
NOT include in this back-up; else it will be > 4 Gb !!!
because the Back-up system adds about 2Gb of "System" data !!!
Perform the Back-Up. The Back-up files will be written to the "D"
drive

3) close up everything and take a look at "D" It should contain your
back-up files, which in my case, were about 3 Gb.

4) Select all of the files on "D" EXCEPT the Manufacture's Recovery
Folder, and "burn"
these Back-up file to a DVD drive using software included in Vista.

5) Check to see that they ALL exist on you DVD ! If so, go back and
delete ALL of these files from you "D" drive in preparation for the
next back-up you wish to perform.

I hope that this solves your Error (08007001B).
