I crossflashed a Liteon lvw 5007 ddw 451 drive to a soho 832 drive,thru omnipatch,on my computer. Omnipatch said drive conversion was successful. DiscInfo read the drive,said it was a soho 832. My problem is,when I reinstalled the drive in the lvw 5007 chassis,the drive door no longer opens. It starts to open,then stops. I can manually open it,but it won't close. It starts to close,but stops. Any suggestions?
