Environment

Novell ZENworks 7 Desktop Management - ZDM7 Imaging

Situation

For some reason, there is not a free sector on track 0 so ISD cannot be saved. It does not already exist on track
0 and there is no free sectors to write it. Something is using all the sectors. The command "dd" needs to be used to clear the ISD.
So after doing the dd if=/dev/zero of=/dev/hda bs=512 count=62 seek=1

the hardware is picking up the image and ISD is being updated (and so its not going in a imaging loop). However, hardware where'dd' has not been done does not update the ISD and so goes on an imaging loop.
The commands used are:
dd if=/dev/zero of=/dev/hda bs=512 count=62 skip=1

or

dd if=/dev/zero of=/dev/hda bs=512 count=62 seek=1

Resolution

This will be an issue whenever there is no space on track 0 for ISD (any release, past or future). If a test program or something uses all the sectors on track 0, then ISD cannot be written.
