| Problems Creating Staubli JC3/JC4 Disks |
|
With the launch of the new Staubli JC3/JC4 driver in 2002 most of the problems of working with Staubli JC3/JC4 loom disks have been addressed. The root cause of any problem remains the same. The JC3 and JC4 loom diskettes use a nonstandard diskette format which means that Windows cannot read from or write to the diskette in the normal way - low-level "direct-to-disk" which bypass the normal Windows disk read/write functions must be used and this can lead to some problems. There is a known problem when using the LS-120 "SuperDrive". This device is a single disk drive that can be used with standard 1.44 Mbyte floppy disks or with special 120 MByte "superdisks". This introduces and extra layer of complexity when working with JC3/JC4 disks and read/write operations may sometimes fail with this drive. Regrettably there is nothing we can do about any problems with the LS-120 drive and can only recommend fitting a standard 1.44 MByte floppy disk drive as the best way to resolve this. Any other problems can usually be resolved either by reformatting the diskette under Windows (use the full format option and not the "quick" format option) or by discarding problem diskettes altogether. The following tips may help - The more often a diskette is written (not read from) the more likely there will be problems so try not to reuse the same diskette for every loom file. If you have a problem with a diskette then re-format it under Windows. If the problem persists after formatting then discard the diskette and use a new one. Writing to a diskette using more than one computer can also cause problems due to slight alignment differences between disk drives. Try to use the same diskette on the same computer where possible. |
