I have bought 2 of these and both were installed by a professional. Both units went on Hitachi drives and BOTh gave E64 errors on startup (supposed to be E65)
We have spent months trying to sort out the issues, but there is NO support in English, so they are being discconected now and thrown in the bin!
Stay away from these, atleast until they decide to offer full support for their customers.
Since my last comment was erased i am going to post it again. Just to warn people how does discoazul.com works. I have bought a supposly new hitachi 47 drive for my xbox360 to replace the old one (47dj). But the problem is the drive only reads games, orginals and backups like 1 in 20 tries... The drive as clear issues and the support is simply terrible. SECOND POST DELETED BY THEM.... i wil not rest till you reply to me the proper way and refund me for your bad hardware.
