Imaging T5570e with W7E

Hi,

we have a customer that uses some old HP T5570e with Windows 7 Embedded.

I wanted to update those devices via HPDM 4.7 SP5 and downloaded the most recent operating system, Windows 7 Embedded 6.1.7601.290 from the official downloads:

http://h20566.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5148839&swLangOid=18&lang=de-ch&cc=ch&swEnvOid=4089

I extracted the exe-Files and imported the image to my HPDM.

Now I wanted to push the image to a client but I get the error "The device has not enough space for imaging" which is correct. The imagefile is 4.995.724.826 bytes, but the harddrave in the t5570e has only 4.093.636.608 bytes.

How is this supposed to work? Am I doing something wrong?
