Hey,
My 960GB SanDisk Ultra II SSD just died... it was working perfectly, I put the laptop into sleep mode, then when I woke it the next day, the system locked up. I held the button to shut it off, and when I turned it on, the drive wasn't detected. This same thing has happened a couple times in the past, and has always snapped out of it after a few reboots, but it doesn't seem to be coming out of it this time. From my understanding, it has the Marvell 88SS9189 controller (I haven't opened it to confirm).
The system can tell that the drive exists, but the BIOS shows EMPTY EMPTY EMPTY, where it normally shows MFR, model, etc. If the drive is disconnected, it shows nothing at all (not even EMPTY). Also, if I connect it to a Linux box and check dmesg, I get: link is slow to respond, please be patient (ready=0) COMRESET failed (errno=-16)
Has anyone diagnosed a problem like this before? Any ideas of a possible solution (at least to recover data)?
I don't have a LOT of data on there (nothing critical), but there's some stuff I'd like to get if possible (I made a backup a couple months ago, but I can't find it :-/ ). This forum seems to be one of the few places that actually digs deep into drive recovery, so I figured I'd ask here. Mainly I'm looking for some advice on possible/probable problem. The drive is still under warranty, so I'd rather not open it up if I'm extremely unlikely to find anything. But if a blown polyfuse, shorted FET, or something along those lines is a common cause of a problem like this, I'd take the risk.
Background on me: I'm an electrical engineer, comfortable soldering tiny components (including BGAs) under a microscope. Familiar with dumping flash chips, hex editors, etc. I've recovered a dozen or so rotating drives over the years, but SSDs are new to me.
Thanks, Pat
