As more people have switched to Windows 7 I would have expected more problem reports. It seems that Ellion have solved the issue in their newer models and probably don't pay attention anymore to the elder models: HMR700A and HMR350H.
It seems that the problem is not Windows 7, but ... the antivirus / internet security being used. All credits to the genius http://consumerelectronicshacker.blo...1_archive.html
He mentions that Norton Internet Security 2010 has got the problem and version 2009 hasn't. I am using G Data Internet Security 2010 and have got the problem. Just checked my wifes laptop (same Windows version) McAfee Internet Security 2010: NO ISSUE !!!
Norton and G Data seem to mark the NTFS partition which makes it unreadable by the Ellion OS afterwards.
Below a summary. Feel free to extend this list:
Cooperate with Ellion (HMR700A/350H):
Norton Internet Security 2009
McAfee Internet Security 2010
Brick the Ellion:
Norton Internet Security 2010
G Data Internet Security 2010
I don't say that products are good or bad; personally I like G Data very much. It is just the cooperation with the most recent not updated Ellion firmware of March 2009.
Hope this helps people having this terrible issue,
