<<< NOTED::NOTES$7:[NOTES$LIBRARY]HACKERS.NOTE;1 >>> -< ** Hackers ** >- ================================================================================ Note 1533.112 Announcing DFU Disk and File Utility 112 of 112 UTRTSC::DORLAND "The Wizard of Odz2" 133 lines 29-NOV-1996 08:30 -< DFU 2.4 ECO kit available! >- -------------------------------------------------------------------------------- INTERNAL USE ONLY DFU 2.4 Eco 1 Release Notes =========================== To : All DFU subscribers 1. Introduction --------------- Several problems have been discovered for V2.4 of DFU. This new ECO kit fixes all known problems. This ECO kit is now available as : UTRTSC::SYS$PUBLIC:DEC-AXPVMS-DFU-V0204-1-1.PCSI;1 (Alpha) UTRTSC::SYS$PUBLIC:DEC-VAXVMS-DFU-V0204-1-1.PCSI;1 (VAX) This kit will bump up the I2.4 version of DFU to I2.4-1. Installation of this kit is recommended if you are using the VERIFY/DIR command. See .5 for a description of all the fixes. 2. Before you install ECO 1. ---------------------------- Before you install this ECO kit you must check the following : - Installation is done via the PRODUCT INSTALL command. This means that this ECO kit con only be installed on VMS V6.1 and higher (up to and inluding VMS 7.1). - If DFU is INSTALLed (via DFU$STARTUP) you must manually remove DFU via the following command: $ INSTAL REMOVE SYS$SYSTEM:DFU Failing to do so will result in problems during installation. - This kit is INTERNAL USE ONLY. Do not install this kit outside Digital EASYNET. 3. Installation procedure. -------------------------- After copying the kit to your own directory installation is performed via the following command : $ PRODUCT INSTALL DFU/SOURCE=:[your_directory] During the installation you will have the option of installing the documentation. This kit is a full installation kit and can also be installed even if DFU has not been installed before. 4. Restrictions and support --------------------------- This version DFU is strictly INTERNAL USE ONLY. Apart for this release notes I have not changed the original V2.4 documentation. Also the help file is unchanged. The installation procedure no longer offers the possibility to install to a private directory. Instead a new file SYS$SYSTEM:DFU.EXE is created; you may want to move the file from there to your own directory. Support as always is not official, but I appreciate any problems reported to me at UTRTSC::DORLAND or ton.dorland@mts.uto.dec.com. You may also post replies to note 1533 at NOTED::HACKERS. I will try to fix any serious problems found with DFU. 5. Problems fixed in ECO 1 -------------------------- General fixes: - Previous versions of DFU always required an exact device name (or a logical name). As of ECO 1 DFU allows some more freedom, eg. if the device is named $1$DIA1 DFU will now also accept DIA1, or even DIA if there is only one DIA device. If the device name is not unique DFU will display the new error message : %DFU-E-NOTUNIQ, Device name is not unique - Some DFU commands flushed the disks ACP caches when it was not really necessary Fixes for VERIFY/DIR: - The VERIFY/DIR/FIX command could result in a computable loop - VERIFY/DIR and some other commands could result in an ACCVIO if the directory was not named .DIR;1 - Sometimes VERIFY/DIR would report a directory as invalid. This could only happen if the first directory entry in a block was exactly 256 bytes large. - Files with 'lost' backlinks are now correctly reeentered in the original directory Fixes for SEARCH: - SEARCH/FULL did not properly display the file date fields. An ASCII date field is 23 bytes, but DFU only displayed 21 or 22 bytes. - Fixed a rare problem where SEARCH resulted in files with '[]' as the resultant directory. This could only happen when BYPASS privilege was disabled. Also DEFRAGMENT/LBN sometimes gave a NOVOLSET error; this problem was caused by the same bug. - SEARCH /FORMAT /APPEND did not work due to a bug in the command definition file. Regards and have fun, Ton Dorland
