Meu SSD foi usado no meu MacBook depois de um mês sem nenhum problema, o SSD não é mais utilizável. Eu não posso montá-lo, não posso formatá-lo. Eu não sei o que fazer. Eu não me importo com qualquer perda de dados, mas eu quero meu SSD de volta no meu MacBook é um SSD de 480GB e era caro desperdiçá-lo.

GPT PMBR size mismatch (937703087 != 937703086) will be corrected by w(rite).
The backup GPT table is corrupt, but the primary appears OK, so that will be used.

GPT fdisk (gdisk) version 1.0.1
Warning! Disk size is smaller than the main header indicates! Loading
secondary header from the last sector of the disk! You should use 'v' to
verify disk integrity, and perhaps options on the experts' menu to repair
the disk.
Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: damaged
****************************************************************************
Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.
****************************************************************************
Command (? for help): v
Problem: The secondary header's self-pointer indicates that it doesn't reside
at the end of the disk. If you've added a disk to a RAID array, use the 'e'
option on the experts' menu to adjust the secondary header's and partition
table's locations.
Problem: Disk is too small to hold all the data!
(Disk size is 937703087 sectors, needs to be 937703088 sectors.)
The 'e' option on the experts' menu may fix this problem.
Identified 2 problems!
Command (? for help): x
Expert command (? for help): e
Relocating backup data structures to the end of the disk
Expert command (? for help): w
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N): Y
OK; writing new GUID partition table (GPT) to /dev/sda.
The operation has completed successfully.
