With version 2 we have changed the test approach because we saw that a lot of times the
test method behind DiskTT was misunderstood. The idea is to test normal file
I/O circumstances using a big file with a bit of file caching (like normal
working conditions). As the RAM in PCs increases, testing must be done with an increasingly bigger
file and therefore DiskTT v1 always suggested a file size
of 3 times the available RAM. But people where testing with relatively small
file sizes what resulted in the
entire read I/O tests being fed from the file cache after being filled through
the initial write. Then they proudly reported read speeds of 700MB/s and more but
you can easily determine that if your hard drive manufacturer reports a sustained
read speed of 100MB/s or so, the 700MB/s value cannot be the throughput of your
hard drive alone.
So therefore we dropped the file caching when testing with the default settings.
You can still enable it but you are warned for inappropriate read results when
your test file is too small. Note that testing on NTFS encrypted or compressed
directories always enables the file I/O cache by Windows internally regardless
of the DiskTT setting.
You can now also vary the block size (chunk size) you
wish to test with.
Good values for block size are:
- 4KB: cluster size on most hard drives
- 64KB: default block size of most RAID controllers
- 128KB: recommended block size of some RAID controllers
- 1024KB: default block size of DiskTT v1.x
Changes for v2.00 release 11
- New: selection of file caching options. In version 1 lots of people were testing their
disks with file sizes that were less than the available RAM resulting in very
high read thruput. In that particular situation the file is completely cached by windows
in
the first write action. After that the read tests are fully read from the file cache
(eg RAM). You are then in fact measuring the speed of the internal memory
through file I/O routines in stead of the harddisk.
- New: when an action is aborted (keyboard stroke or mouseclick) the results
measured
thus far are shown in a hint.
- Changed: set test file size from 10MB up to 100GB.
- Changed: set chunk size from 1KB up to 10MB (in KB).
Changes for v1.2 release 10
- Fixed: occasional Access Violation error after selecting a user defined path (DiskTT
did not crash and the path was selected but not displayed).
- forced screen update after each test (progress bar and results were sometimes
not updated until all tests completed)
Changes for v1.2 release 9
- Fixed: Execution under Windows NT4 failed with release 8
Changes for v1.2 release 8
- Fixed: bug preventing tests > 4GB
Changes for v1.2 release 7
- Fixed: starting the test with the keyboard also aborted it
Changes for v1.1 release 6
- Select drive/directory to test
- Mouseclick/keystroke aborts testing
- Some minor fixes/improvements

KeyLink for Formula 1.31 (build 40)
KeyLink for Formula zet informatie uit een Datalogic Formula Barcode Reader naar een willekeurige PC applicatie over door de data tijdens het downloaden als toetsenbordinvoer naar de PC applicatie te sturen (soft keyboard wedge). Tevens kan een barcodelezer gesimuleerd worden door een CSV file met soortgelijke data door fKeyLink in uw applicatie te laten plaatsen. Met een ongeregistreerde versie kunt u een beperkt aantal records direct vanuit de barcodelezer naar uw applicatie overzetten. Met de download worden voorbeeld configuraties voor Windows Notepad en Microsoft Excel meegeleverd. Het gebruik in combinatie met een CSV bestand kent geen beperkingen.

FileLink for Formula 1.25 (build 38)
FileLink for Formula biedt u de mogelijkheid om met slechts 1 enkele dubbelklik data uit een Datalogic Formula barcodelezer naar een bestand te downloaden. Ook kan FileLink vanuit elk DOS of Windows programma opdracht gegeven worden om tot
downloaden over te gaan. Het programma wacht in de Windows system tray totdat u of uw programma opdracht tot downloaden geeft. FileLink zal vervolgens de data downloaden in een, door u gespecificeerd, bestand zodat uw programma de gegevens kan importeren en verwerken. Een ongeregistreerde versie laat slechts de download van een beperkt aantal records toe.

DL for Windows 1.1 (build 10)
DLW is a small utility to download Intel 8051 .hex files from a PC to a barcode
reader handterminal. It's compatible with Datalogics original dl.exe DOS utility
but faster in download and more userfriendly. DLW is freeware.
Usage:
Start
DLW from the commandline or the startmenu. When started without file parameter a dialog
opens that allows you to select the file to download.
Commandline arguments:
/? - Help
/f
