I may have missed something but is this a crucial SSD? Sometimes they
need to be allowed to sit in neutral (but powered) for the firmware to
tidy up blocks. If you can leave it attached via an enclosure but
*unmounted* for some time (eg overnight) it's possible it will sort
itself out. I've had spectacular results with crucial disks in this way.
If not crucial, then have a look for garbage collection processes for
your disk. The OS doesn't, I believe, handle them all very well (happy
to be corrected as I'm a bit out of date on this).
cheers

Thanks for your suggestion Sam.
My last backup was just under a week prior to the computer not
booting. Fortunately the majority of my work is on cloud-based systems
so only a few files have gone missing. I tried as you suggested about
after 2 hours the drive was still trying to erase itself and the
progress bar had not appeared to move. I have now switched the SSD out
for the original HDD and been able to install a fresh operating system
onto it and the computer appears to be working perfectly. I am
therefore guessing the SSD may be dying. Does this sound a correct
conclusion?
Thank you for your input.

Hello follow SMUG members,
I hope you can advise me.
I have a mid2012 MacBook Pro which today has given me the flashing
folder with questionmark symbol and refuses to boot into Mac OS.
Historically when this has happened it has been the HDD cable which
once swapped out fixes the issue.
I have booted into internet recovery, opened disk utility and I can
see the SSD. Therefore it cannot be the HDD cable at fault on this
occasion. I can not verify or repair the drive.
Remaining in internet recovery I go to start up disks and this does
not show the SSD as a boot option. I have also tried selecting
reinstall OS X with a view of repairing the OS files but again there
is no valid install location.
It is also important to note that the SSD has been protected using
FileVault.
My questions are:
What affect will FileVault have on getting my Mac to boot again?
Can this be fixed and if not what is likely to be the component at
fault?
Does anyone have any recommendations on what the problem is and
steps to fix this?
Ideally I’d like to get this Mac working again as it is such a
great computer. I have looked at the new MacBook Air but the only
thing that stops me swapping is the lack of ports and I prefer the
old keyboards which have travel on the keys. But if you have
experience of this Mac I’d love to hear your experiences as if
this Mac is beyond ecenomical repair then the Air is my first choice
for replacements.
Thank you for all contributions in advance.
Ben
