cross posting is against forum rules.

this post is also off topic in this forum. this particular forum is about BenQ Drives.

Hmm, HP 400c is a Philips OEM, basically a BenQ DW805A IIRC… :flower:

[I]diane onofre[/I], make sure you get right firmware.
Your drive is for sure out of warranty so you might also consider a crossflash to BenQ/Philips firmware. Read carefully before you do this.
