080944 - This thing plugs into the USB port on the computer.  The cable is
080945 - much too short.  We could place it on top of the CPU, which would
080946 - eliminate cable length as an issue.
080948 -  ..
080949 - The power cable is another thing that takes up two power recepticles.
080950 - Had to change confirguration of power connections to have enough
080951 - outlets for this new hardware.
080953 -  ..
080954 - Displays as drive L.  We could change the settings, but not sure
080955 - there is any advantage, if we go about plugging the thing into other
080956 - systems.
080958 -  ..
080959 - Good news is that DOS copy commands work with the drive, and it is
080960 - already formatted.
080962 -  ..
080963 - The drive shows 494 GB using 32K cluster size.  This indicates that 4
080964 - GB may be used for the file management process.
080965 -
080966 -        [On 070314 changed format from FAT32 with 32K clusters to NTFS
080967 -        with 512 byte clusters, ref SDS 11 649K, increased storage by

080990 - Need a batch file that can take year and month as parameters, and
080991 - construct directories and perform backup.
080993 -  ..
080994 - Could omit parameters.  Create a utility to get the date from the
080995 - system clock and then build and run a batch file to do the full file
080996 - backup.  It can be executed at night, so it doesn't matter how long it

081006 -              support. ref SDS 10 VG3V

081008 -        1.  Data transfer seems very slow, but not sure.
081009 -
081010 -            Initial backup today using drag and drop for 3 GB, seemed
081011 -            to take about 30 minutes. ref SDS 9 FG7K
081013 -             ..
081014 -            Seems like if this were an internal drive, work would be
081015 -            much faster connected through the system bus?

081017 -                [On 070314 formatted drive to use 512 byte clusters,
081018 -                and developed new batch file toos for backup;

081024 -        2.  Defragmenting takes forever, even with only 1% use at
081025 -            this time.  Does this reflect 1 large drive???
081027 -             ..
081028 -            Maybe after initial defragment op, subsequent passes will
081029 -            be faster?
081031 -             ..
081032 -            Normally takes from 10 seconds to defragment drive c that
081033 -            is 20 GB to maybe 90 seconds to defragment drive h: that is
081034 -            14 GB but has the SDS subject index files that get highly
081035 -            fragmented due to high use and continual construction.

081044 -            Can the drive be formatted with Microsoft XP standard tools
081045 -            for NTFS protocol using a smaller cluster size for more
081046 -            efficient use of space?

081053 -                the Hitachi drive can be formatted with NTFS to use
081054 -                smaller cluster size; went ahead and did that.

081075 -             ..
081076 -            Since the drive has a separate power supply, and switch,
081077 -            should the drive be turned off when not in use?  Is there a
