My macbook pro mid 2012 won’t read my ssd internally as well as externally.

My macbook pro was working fine for 2 years after upgrading to an ssd, but suddenly yesterday a question mark appeared during the startup, i tried internet recovery and my ssd wasn’t showing in the disk utilities, i tried changing the wire, and again tried it up with a new wire, but it also failed to read my drive, finally i enclosed my ssd into a sata to usb and tried to boot it externally by pressing alt during the startup, unfortunately it didn’t work, now i tried to read it via disk utilities, in the disk utilities i can see my ssd as an external drive but only with 35 gb capacity and the rest is unknown, tried to format it, but there is an error code the drive has bad sectors and failed to format. Usb serial number if the ssd is 00000000000, could someone help me, thank you.

MacBook Pro 13″, macOS 10.15

It sounds like the SSD may have failed.

Since you don't seem to have a bootable macOS external drive to check the health of the SSD you can create a bootable Knoppix Linux USB drive. You can use the downloaded Knoppix .iso file as a source for Etcher (Mac/Windows/Linux) for creating a bootable USB drive. Option Boot the Knoppix USB drive and select the orange icon labeled "EFI". While Knoppix is booting the computer may appear frozen on the boot picker menu so give Knoppix lots of time to finish booting.

Once Knoppix boots to the desktop click on the "Start" menu on the lower left corner of the Taskbar and navigate the menus to "System Tools ---> GSmartControl". Within the GSmartControl app double-click on the SSD to access the SSD's health report. Post the complete report here. GSmartControl can also run the SSD's internal self-diagnostics if available.

Even if the SSD appears to have errors or fails the selftest, all is not necessarily lost as sometimes there are ways to "fix" an SSD to make it work properly again. The health report and results of the self-diagnostic are important to determine what may be happening to this SSD plus it will provide us with the exact model and firmware revision.
