Spinrite is a $90 utility. All the documentation is for xp fat32 HD and
uses an a:floppy drive to boot msdos from. Sent them a email about
outdated documentation. Got reply saying no purchasers in many years so
not going to update their documentation. Sure sounds like a dead product
Since the mbr was deleted looks like win10 got a malicious virus that
made the external usb HD un-mountable and screwed with the last file I
had open. Nothing physically wrong with the HD.
All ready used dd_rescues and recovered 50% of user data which had no
i/o errors. dd_rescue could not fix any of the i/o errors.
Read the man on dd and found no mention of skipping "free space" IE;
unused space in the allocated partition.
Only 600gb of data on the 3tb HD.
Looking for method to copy this data to 1tb HD bypassing i/o errors.
