SSD problem can't format

Out of nowhere suddenly my MacBook Pro got into the folder with blinking question mark mode and I wasn't able to boot.

I then started up from internet recovery, it seems that my SSD is messed up. In the process of erasing it, it got into an error like "waiting for disks to reappear"

At that point I took out the SSD and used an adaptor to connect to other Mac, still I can't erase the disk using MacOS GUID partition mapping and create a journal format partition from the other Mac while formatting,

Wiping volume data to prevent future accidental probing failed - Operation failed!

ssd is able to create partitions through pdisk

I was hoping you had a Toshiba unit Apple recall: MacBook Air at risk of catastrophic SSD failure as it had a recall a few found their way into MacBook Pro's. The recall has ended but it would have explained things.

At this point I thing you'll need to visit an Apple Store to see if they have any tricks up their sleeves. IT does appear you have a few partitions which is messing things up I was hoping you could have nulled the drive and then created a fresh partition map & partition (MacOS).

how to null the drive and create fresh partitions!? can you guide me or link to the process :)

Thats what we did already using FDISK deleting the partitions. As I explained above.

Just use FDISK to remove all of the partitions from a different system via Target Disk Mode or using an external case to hold the SSD, don't make any partitions!. Then pop the drive back into your system if needed and use a bootable OS installer USB thumb drive following this: How to create a bootable macOS Sierra installer drive. Then use Disk Utility from it to create the GUID partition map and setup the Journaled partition (only one). Then run the OS installer to install a clean OS.

I did that using fdisk.. it stated no partition map exists.. then i plugged it back to create one journaled partition but still no hope.. it again stuck at waiting for partitions to activate

There's only few logical problems in here:

  • Your SSD is corrupted
  • Your SSD has been damaged

Best solution here is to try with another drive to boot, or get a new one if you still have warranty on it.

If the drive is still detected but won't read, write, boot, repair, etc, then your drive is corrupted and can't be used sadly as this is a problem that can't be fixed most of the time.

If you can, try to at least get important files from that SSD using your other Mac if that's still possible.

Which macOS are you using?

Try to format your SSD using Disk Utility.

high Sierra.. disk utility is not helping

High Sierra uses a newer format! APFS So you do need to use anther Mac which has High Sierra to format and setup the drive. You also want the newest version of High Sierra as Apple has been fixing a few issues

is it so really? should I approach that method.. because I don't have another mac with high sierra

@saisanthosh - Sorry guy, Apple zinged us!

The only way I can think of to redo the drive is to connect it to an MS Windows or Linux system so you can completely wipe it down. In doing so you'll then need to use Internet recovery or if you have it already a Sierra OS installer USB drive (not High Sierra) That way you don't get mired into AFPS issues.

I already did that.. I cant able to format it using gparted in linux

I had an Apple-label Samsung SSD in a Mini go bad -- it could be read, sort of, but many disk operations were unsuccessful, and formatting it just crashed.

So I replaced it.

But eventually I was able to revive the Samsung by connecting it directly to SATA in a PC and formatting it as a Windows drive using a freebie Wintel disk formatter.

Then I was able to use a USB case to connect the SSD to a Mac and format it as APFS.

I had a similar issue on a 2011 iMac. I was trying to upgrade to a SSD, and it simply would not take it. I tried multiple SSD’s, , cloning before putting it into the drive and booting from the new SSD externally(which worked when external) different format schemes, formatting using terminal, MacSales tech support, additional thermal sensor adapter, you name it, etc. Everything. I ended up putting the old HD back in and it worked fine.

Total mystery. No solution.
