Hi,

I have a huge problem with my computer and I am not at home, I am abroad for an internship.

On friday my computer started to freeze so I forced it to shut down. After restarting the computer, my second partition became unavailable. I ran disk utility and tried to mount it but it was impossible, I repair the disk after verifying it because it was corrupted but I still couldn't mount it. The computer froze again so I restarted it, which took a very long time, then my main partition where OS X 10.8 was installed was unavailable too and it booted automatically on the recovery HD partition. I tried to repair both disk from disk utility and it never worked and eventually it froze again so I restarted then guess what? No partition was available. The computer was freezing on startup, it was stuck to grey screen, sometimes I would see the apple logo then a blinking folder with a question would appear because the startup drive was indeed unavailable... I tried to startup in verbose mode, safe mode, recovery mode NO LUCK and eventually at times I would see an interdiction sign.

Luckily, one of my room mate over here has a mac and I was able to make a bootable usb of Lion OS X. I booted from the usb, tried to repair the disk but it hangs at some points, I tried to format the disk and it always hangs while "mounting" or "unmounting", I tried to erase the disk with partition same thing, for hours it remains "unmounting"... I tried to erase the disk via command line with "diskutil" and it also unmounts for ages and never come through. This is driving me crazy.

When I run "diskutil list" from the Terminal I see that:

Code:
-bash-3.2# diskutil list

I have a macbook pro 13" mid-2009 with 8Gb of Ram and a 250Gb Samsung 840 pro SSD. The latest version of Mountain Lion was installed on it. I do not mind formatting, I have a time machine backup with me and I also bakcup quite regularly important files. I would like to know if there's a solution for this problem... If I were at home I could just install my old hard drive and see if the problem occurs and return the SSD to Samsung but now I am not at home, I do not have my old hard drive with me and I do not want to spend money in a new one if I can fix the problem another way. I need my computer to work, I have a report to write during my internship.

Thanks in advance for your help.

Hate to say this, but from your description it sounds like your SSD is toast. Particularly that bit about not even being able to mount/format it from the Lion USB key. :(

Hook up an external then load Mac OS onto it and use it to boot. Then see what the options you have with the ssd.

Well I got another disc now I will install lion on it. When I will be back to France I wil return the ssd to Samsung it's only 5 months old. I think there's no hope, it drove me crazy... formatting was impossible always hanging. I have no idea what happened but I already had some problems with it once then it went back to normal. I might have got a defective drive.
