I work for a large school district where we use ZENworks to help manage
our computers. Our environment is about 100 schools and several tens of
thousands of computers, and a while ago we encountered a problem with
the following harddrives:

Seagate Barracuda ST340014A in a Dell Optiplex GX270
Western Digital Caviar WD200BB-60CVB0 in a Compaq Deskpro EN
Maxtor 5T020H2 in a Compaq Deskpro EN
Maxtor 6L020J1 in a Compaq Evo

We use asset tags on all of our hardware, and store the asset tag as
the workstation name in imagesafe data so that when a computer gets
imaged it doesn't lose its workstation name, (pretty basic stuff).

However whenever we edit the image-safe data on any of these drives,
all the values appear to be set to zero, and attempting to make any
changes to the image-safe data silently fails, (as in it goes back to
nothing but zeros).

Any ideas? We're running ZENworks 7 SP1 Desktop Management and
NovelClient 4.91 SP2
