I am running Vista Home Premium and trying through "System Restore and
Backup" to create a PC backup to my external hard drive. This hard drive is
functional on my network and shows in my windows explorer. I have also
mapped it to my computer successfully. The hard drive does not require a
user name and password to access.

However when I try to choose this as the destination for my PC system backup
file I am asked to Enter a user name and password to access
\\Mybookworld\public\. logon with my username and password. I'm not sure
what it's asking for, because I am not aware of assigning such to this
external network hard drive.

I logon with my PC user name and password and that seems to work as it goes
to the next step stating..........testing backup location.

Then an error message appears indicating:
"No mapping between account names and security IDs was done. (Ox80070534).
Please ensure that the network location is valid."
I am stumped and need assistance. Please advise if you are aware of what my
problem is.
Thank you,
Michael

MIchael - do not quote me on this, however the file backup provided in
Premium version may not be "compatible" with a mapped drive.

AJR - I have the exact same problem that Michael describes. The backup
location is fully qualified "\\Example\Directory" not a mapped drive. I've
tried every ID\PWD combination I can come up with and continue to recieve the
message Michael recieves or sometimes it says it is an invalid password, but
I can't get past this step in setting up a backup.

Thanks for your help,
Jeff

On a Windows XP machine, bring up the MioNet application and click on Backup
Info.

MioNet does not work with Vista x64. Western Digital claims that you can
use MyBookWorld in native (SAMBA) mode exactly as Michael and Jeff
describe.

I have a machine running Vista Ultimate x64 and I am having the
identical problem. I have also tried using Acronis backup and it
experiences a write error right at the end after it has completed
preparing the image.

Although MyBookWorld has a limit of 1000 files in any directory, at the
point we are experiencing a problem that cannot be the cause.

I'd be grateful if anyone who knows the solution to this infuriating
problem could post a reply here as I have wasted way too much time
trying to figure this out and WD support doesn't seem to own a Vista x64
machine so they can't help!

Philip
