Hi pdp-8, good summary.
Powering SSD to put them in to maintenance mode has been posted on several occasions.
The proceedures are not a secret
Actually Pre warranty return requirements.
I picked it up a few
years ago when a crucial 64GB drive went seemingly fully defective.
Power on no data cable connected fixed that drive and later a couple of others for me.
In a big shop in the city there is a stack of drives which customers insisted be
replaced, customer signs a release form for the shop to dispose of the drives
complying with the GDPR,
They get a factory reset with a tool I have not yet been able to find as software,
my assumption is it only gives a couple of commands and the controller clears all
data, it will also update drive software when available.
Software updater may be available for download, depends on drive and all found
up to now are running on windoze..
Early drives with low capacity go in to fail mode much more often than more modern drives
with higher capacity and more reserves.
USB Sticks powering has repaired several which went read only, that is a manufacturer
data protection mode. San disk ultra seems prone to that issue. Two of my four 64GB
drives went that way. Intent is to prevent further corruption a read only lockbit is set,
you can rescue your data before repair, reset may be initiated during the self repair
and maintenance mode.
That gem came from SanDisk.
