(1) Where do you have SO installed? iSSD or HDD? (2) Do you have iSSD as caching device for your HDD?

Could be another iSSD broken, check the links in: What to do when iSSD fails?

Got same problem, I used it as Express Cache always. It started to take LOOONG times to boot (4-10 minutes depending if blue screen of the death appeared. Sometimes the BIOS will show it, sometimes will show not all the info and sometimes any at all. I fix mine today, read this: http://cookuop.co.uk/asus-ux32a-not-detecting-ssd/ and this: http://forum.notebookreview.com/threads/...-issd-not-detected.679687/page-10 If you need more images for reference maybe you should look at a video on youtube to see how it is UX32VD inside: https://www.youtube.com/watch?v=cqe1-X_klr4 You got to open it with a Torx T5 and try to heat the iSSD a little if you can (though I think I could have saved that part during my fix). Next try to pry it open with some tool (I carefully used a knife) and screw it back again when finished. This one is the enemy! Very little thing! Suerte Samuel. I'm writing this on that PC right now ;)
