~ Nung hindi po gumana yan, anong Error? If after niyan walang error, nung itry mo i-format, ano pong error?
HKLM\SYSTEM\ControlSet001\Control\StorageDevicePolicies
~ Pinalitan mo na ba yung value niya ng 0? Tapos nag-restart ka na ng PC tapos ayaw pa rin?
Nung i-try mo to sa DISKPART "attributes disk clear readonly" tapos after nung "clean" command, anong error?
If ayaw din sa diskmgt.msc as per suggested by
zaldhie, try using Minitool Partition Wizard Free. Look for the USB drive letter. Delete partition. Apply. Then, try mo na i-reformat. If mag-error anong sabi?
Pwede mo din i-try yung USB Write Protector sa Softpedia to unlock the drive.
