I have an external WD SSD in great condition , with healthy data , used on quality computers with security software , new cables , and a power surge protector .
this week - data partially disappeared from the Exfat drive . there is no reason for this . i do remember my computer freezing while running software and the drive not mounting or something .
anyone have any Terminal commands for repair ?
Mac shows it as both partitions being perfectly healthy - except head parent drive WD Exfat having that error seen below :
"First Aid process has failed. If possible back up the data on this volume. Click Done to continue."
"Fixing damaged partition map."
"Couldn’t modify partition map. : (-69874)"
"Operation failed…"
* Mac First Aid indicates an error .
* Windows seems to scan and verify it as healthy with the error checking tool .
* WD Discovery Utilities diagnostics shows it as completely healthy on all three stages of scanning .
* EASE US Partition Master surface test shows completely healthy all sectors .
Since the drive has been protected greatly , I know for sure this is a soft error and that minor adjustment could bring my data back .
I'm trying to image the drive and secondarily recover it , but it's having trouble completing those processes due to this error .
It is MBR exfat , an external device with two partitions . I never have had a problem with this device before now .
I am considering reformatting it to get rid of this error kink , but want to seek a repair first . It's kind of painstaking to erase then recover , and I have always had unfailing luck with soft diagnostic repair as my drives are standard quality and well cared for .
Would it help if I used a third party software and convered MBR to GPT ? would that fix this error ?
any Terminal commands like FSCK and diskutil for minor repairs ? thanks
