SSD formating trouble and mysterious disks


thanks for helping! Two days ago suddenly Apple services started to fail on my Mavericks machine. I couldn't shutdown (logind - or something like that - crashed but could not be force-quit). I shutdown twice from terminal. Then I wanted to repair whatever is happening from recorvery mode. I don't remember the message but the next thing I know it won't boot anymore.


Now when I use the (internet recovery/DVD) disk utility I usually can't format the SSD (Samsung Evo 840). In these cases sometimes the drive disappears from the Disk Utility (also from Terminal, there's just no /dev/disk0 anymore). Restarting helps, though. Sometimes I can format but then my TimeMachine hangs at deleting the disk when restoring. I also took the SSD out and did a long (not the short one) exFAT format on a windows machine. Afterwards I could format it back in the mac to HFS+, but no luck again with the TimeMachine. I tried dd if=/dev/zero ... but still the same.


Here's what diskutil gives me right after deleting and creating a new partion with HFS+ and GUID (disk0 is the SSD, I have no idea what disk3-12 are but they are multiplying slowly but not consistently during my repair troubles):

Can anyone help me figure out how to properly format the disk (and what to do with the disk4-13?) Many thanks!
