Hello.

I have WD6400BEVT-00A0RT0 disk with many bad blocks. I want to return it to RMA but I have problem. My disk on the bios, HDTune or WD diagnostic program is recognised as WD5000BEVT-00A0R0 (the serial number on label is the same as on programs )I think someone modify original BIOS/Firmware. Is any chance to replace wrong software to original ? Can I do this on my home with my PC ? I search for .rom files on hddguru but I didin't find for WD6400BEVT-00A0RT0.

Send regards.

p.s Sorry for my poor knowledge of English, I am from Poland.
