Sounds sort of like the AmigaDOS disk "validator".  You described a
system crash and when things came up again the drive spent 5 minuites
blinking it's light.
If it's the validator then what happened was this:  The crash prevented
AmigaDOS from from perfroming a final update on the hard disk.  Next
time things where booted AmigaDOS noticed somehting "strange" and decided
to validate the ENTIRE disk.

AmigaDOS keeps a lot of links that can be used to reconstruct most of
even a badly mangled disk.  THIS IS A FEATURE!  If you happend to zap
the dual copies of the FAT on an IBM disk you be "up data creek without
any file links".  (Your data would be quite scrambled)
