回答“Bios sometimes does not recognise my Sata HDD”Turns out there is a ribbon connecting the SATA daughter-board and the motherboard on the Asus R556 series laptops which is faulty. There are two fixes; reflow the traces at both ends of the ribbon (it’s easy to identify, as it crosses the HDD caddy), or purchase a new ribbon, daughter board and ribbon connector (for the motherboard interface). Personally, I am inclined to agree with you, ‘Planned Self-Termination’. :/ ….and Asus used to be so good too. :(
回答“Bios sometimes does not recognise my Sata HDD”Same issue here. Bought a replacement hard drive for this laptop and it will not show the drive after the first time I booted the device to install windows. This is the third hard drive I have tried in this machine and each time it’s the same issue; works for a short period of time and then the drive stops being recognized by the system at all. I have cleaned the connections, tried a reflow of the daughter-board which has the SATA connector (and the motherboard too). Then tied a new HDD… NOPE. Fails within 30 minutes of the install. Bottom line is this is a very poorly constructed laptop with poorly engineered parts. This was supposed to be an easy refurb for a friend, and it’s just turned out to be a money pit. I do not recommend the Asus R5XX model line, and will be going back to Toshiba.
