NON DOS FORMAT
The Flash device you have accessed may not be properly formatted. If so,
and you have previously formatted the card for Flash software other than
TrueFFS, the device needs to be reformatted with the TFORMAT
command to work with TrueFFS.
It may be that some drivers installed on your computer use overlapping
memory resources with TrueFFS, and hinder its access to the hardware.
Check whether any other installed driver uses overlapping resources. Also,
if you are using a memory management driver such as Microsoft's
EMM386, Quarterdeck's QEMM or Microsoft's MemMaker, make sure to
exclude memory areas used by TrueFFS.
ERROR WRITING DRIVE XX
A physical Flash write fault occurred several times in succession. The last
write or delete operation did not succeed.
Answer "R" (Retry) to the Retry, Abort, Ignore query. If the error persists,
answer "A" (Abort) until you return to the DOS prompt or to your
application.
The cause may be one of the following:
• The power supply is inadequate, and cannot sustain a Flash write.
• The Flash components are worn out (this will occur only after
prolonged use), or possess some other physical fault. This situation
can be recognized by faults occurring sporadically.
• The TrueFFS format is damaged. In this case TrueFFS
automatically assumes the read-only mode to prevent further
damage.
