ZCM 11.2.3 USB IMAG. - attempt to access beyond end of devic

Hi There,

this may have been covered before but i have searched and had little headway into the issue.

I am getting the following errors shown (thousands) on the "Alt-F4" screen whilst imaging.

[xxx.xxxxxx] sda1: rw=65, want=xxxxxxxxx, limit=xxxxxxxx
[xxx.xxxxxx] attempt to access beyond end of device

I have checked that the tntfs.ko has loaded.

I am using USB imaging with ENGL 8.0 and 11.2.3.
The drive is a USB 3 1TB with 10gb fat32 partition for boot and Remaining EXT4 partition for images.

The images will apply on some machines but fail half way through on others....

is it something to do with partitioning etc?

any ideas?
