FWTSETUP.EXE
T2090 setup program (discussed later in this chapter in “Setup Menu”).
Syntax
c>fwtsetup
CLEANUP.EXE
This utility program is intended as a performance enhancer for applications
that perform a large number of disk writes during their execution. To
understand what this file does, it’s necessary to describe how a disk drive in
flash memory operates.
Flash, unlike a real disk, cannot just be written over by new data. The area to be
written must first be erased. For this reason, as the flash disk is written to or as
files are deleted, blocks of flash are marked as dirty (that is, used and needing
erasure). When the time comes to use these blocks, valid data is copied from an
entire 64K zone into a spare zone, then the dirty zone erased. The device driver
itself periodically performs this cleaning operation automatically during the
process of reading and writing to the C drive. This automatic cleaning typically
ranges from 0.5 to 3 seconds, depending on the condition of the flash at the
time.
In situations where large blocks of data are to be written to the drive, or latency
times for writes are important, performance can be improved by first cleaning
the disk manually. CLEANUP.EXE looks at the entire drive and collects all
dirty blocks, making them available for writes. This delays the need to
automatically perform a cleaning function for a significant period of time.
Syntax
CLEANUP 80 /S
(from the command line)
CLEANUP C:./S
(from a batch file or CTT mode)
where:
<80>
specifies drive C for the T2090.
/S
prevents any nonfatal messages from appearing on the screen (Silent mode).
