Apple SSD SM0512f Samsung not showing in Disk Utility

If you did not delete the Bootcamp partitions with BootcampAssistant, they are still not available space.

Can you start the Recovery Partition still? Start while holding the CMD+R keys. If you can (small chance, but you never know), start Terminal from the menu:

then copy/paste the following command, and Enter:

diskutil list

Can you post the output here?

You did the Windows installation with BootcampAssistant (?), and you removed the Windows installation with BootcampAssitant (?), then installed W10 withBootcampAssistant (?).

From the external Windows drive can you see the internal drive partitions? what sizes do they have?

and the format of those partitions?

Looks normal except for the name Macintash HD.

can you check how much is free on the Apple_HFS partition ?

In fact I don't understand why it will not be visible in DiskUtility.

Hello everyone and let me thank you for your time in advance.

I am posting because I face a very weird situation with my MBP. Model is MBP 15" mid-2014 (1TB ssd, nvidia discrete graphics), only factory parts. The machine lately was experiencing kernel panics (launchd died\nState at Last Exception:\n\n"@/SourceCache/xnu/xnu-2782.40.9/bsd/kern/kern_exit.c:363) which I thought to be associated with Google Chrome since they occured while browsing or watching online flash videos (youtube etc ...).

I purged chrome and the kernel panics stopped although occasionally the MBP would be slow. I decided to upgrade to 10.11 (El Capitan) only to find out that my SSD is not recognized by the El Capitan installer. When I get to the choose a hard drive screen, only my USB (from where I install El Capitan) shows up. The ssd is not detected. I tried the disk utility found on the El Capitan installer but the disk is not detected there also. Then ssd is also not detected in the Disk Utility in the Recovery mode (tried both internet and local). Only the "MAC OS X base system" disk image partition appears when booted in Recovery.

Additionally the system never gets past (spinning wheel of death, hard shutdown) the login screen in safe mode and has a kernel panic (Your computer restarted because of a problem ... and the panic report lists the same message as above) in every second try to log in in safe mode.

The weird part is that the machine boots fine in normal mode (I am writing this message after a normal boot) and disk utility (while booted in Yosemite) detects, verifies and repairs the ssd in normal mode. I do not get the flashing question mark or have any problems with normal login process. I must have rebooted around 30 time today in normal mode. Also the Macintosh HD can be selected as the boot disk with restart and holding "Option".

Tried SMC reset, NVRAM reset, tried to use fsck from single user mode. In the first attempt fsck returns "The volume Macintosh HD appears to be OK." while in the second execution fsck returns fsck: disk1 media not present (disk1 is obviously the ssd).

The entire machine and the ssd appear to be working normally and as expected in 10.10.5 but cannot upgrade and all the above signs are not hopeful. It buffles me that I can boot normally to 10.10, I had faulty disks and whenever the disk was not detected in Recovery mode I was alway getting the flashing questionmark to indicate that the disk is corruted. Is there any chance that I have messed something up in my partition table thats why the ssd is not detected up or am I looking at a faulty ssd that for some reason is still bootable and appears to be functioning??

Any ideas at all .....

Thanks guys

My ssd model is the same. I have no idea if there is any problem with these samsung drives. When I get to Disk Utility in Recovery Mode and try to repair/verify the drive I receive a "Alert: some information was unavailable during an internal lookup" message and the SSD then disappears from the list. The weird thing with my system is that I can boot normally in my machine and successfully run verify/repair from disk utility in live mode.

Can you boot with the normal process ?? how about in safe mode ??

Could you elaborate more? Just installed new Samsung 850 evo ssd and cannot see the drive in disk utility or when trying to select a destination disk for restoring a time machine. Thanks!

NVRAM, PRAM, SMC reset...Your macbook needs to be reconfigured to recognize the new hardware.
