sl@0: =head1 NAME
sl@0: 
sl@0: usbinterop2.pl - Create drive-filling file, read back and compare
sl@0: 
sl@0: =head1 SYNOPSIS
sl@0: 
sl@0: usage:   usbinterop2.pl [options]
sl@0: 
sl@0: =head1 OPTIONS
sl@0: 
sl@0: =over 4
sl@0: 
sl@0: =item --size=<size of files to create>
sl@0: 
sl@0: The size in bytes for the test file.
sl@0: 
sl@0: Default value is "1024".
sl@0: 
sl@0: =item --drive=<USB drive location>
sl@0: 
sl@0: The path to the USB drive in which to write the files.
sl@0: 
sl@0: Default value is ".", the current working directory.
sl@0: 
sl@0: =item --help=<file>
sl@0: 
sl@0: Displays this help.
sl@0: 
sl@0: =back
sl@0: 
sl@0: =head1 DESCRIPTION
sl@0: 
sl@0: This is a simple utility to create a file that fills the USB drive as
sl@0: much as possible, and reads it back to verify its contents.
sl@0: 
sl@0: =head2 Test Case Specification
sl@0: 
sl@0:  TestCaseID:	Interoperability_2
sl@0:  TestType: 	IT
sl@0:  TestCaseDesc:  Test Mass Storage functionality on different platforms
sl@0: 	        (Windows 2000/XP/ME, MacOS) (Manual test)
sl@0:  FssID: 	Base/emstore/1.1.1
sl@0:  FssID: 	Base/emstore/3.1.1
sl@0: 
sl@0:  TestActions:
sl@0: 	Connect device to a host PC. Enable MS. Start perl script on
sl@0:  PC.  This script formats drive and queries size of it.  Than script
sl@0:  create file with size close to drive size and check free space.  Then
sl@0:  script prompt ask to unplug/plug USB cable (to flash OS read cache)
sl@0:  and then read the file back and compare.
sl@0: 
sl@0:  TestExpectedResults:
sl@0: 	File creation should succeed. Read data from file should match
sl@0:  with written.  Sum of file size and free space should be close to
sl@0:  drive size.
