D2D - Disk To Disk Pack Copy; 24-Jul-81:
D2D (disk to disk) copies an entire disk pack to another
disk pack. Using Super-USETI and Super-USETO (SUSET.)
instead of LOOKUP and ENTER, as well as performing its own
file space allocation and Storage Allocation Table (SAT)
management, results in a fast copy. At the Univesity of
Texas at Austin, copies of RP06s using FUR which run 4 hours
are performed in 40 minutes with D2D. Unlike "image" copy
programs which also use SUSET. but simply copy block to
block and result in a useless BADBLK.SYS, D2D creates a
refreshed pack with a valid BADBLK.SYS.
