GammaTech Utilities

GammaTech Utilities includes the Analyze utility, which will scan your drive for media errors and automatically mark bad sectors. The GammaTech Utilities Information object, also included, describes the use of the Analyze utility in addition to the 24 other utilities which comprise the GammaTech Utilities.

Features

 * Analyze
 * View a list of sectors which have been marked bad.
 * Automatically mark bad sectors as bad has been added.
 * Automatic updating of the HPFS checksum values, as appropriate.
 * Comprehensive analysis of sectors found bad is performed. The ownership of a bad sector is identified and reported including the type of sector and what system area or file it belongs to.
 * DiskMap
 * This utility graphically displays the layout of FAT or HPFS volumes making it easy to identify bad areas and determine the amount of fragmentation on the volume.
 * FatOpt
 * A graphic display of the optimization process is displayed.
 * A display only option is provided as well as trigger parameters which allow optimization to proceed if fragmentation exceeds the specified level.
 * Specify that the "EA DATA. SF" file be, or not be, defragmented.
 * Additional information about the volume and files is displayed.
 * Files
 * The Find utilities provides easier file maintenance as well as provides significantly improved functionality.
 * The main dialog provides extensive file selection criteria. You may select files in most any imaginable way including comments, text, file size, file age and attributes.
 * From the main dialog you may delete, move, copy, set timestamps, alter attributes, or search for the specified files. If the search option is selected, a list of the matching files is displayed.
 * From the file list, you may select and deselect one or more files and then execute any of the functions above. From the file list you may also choose to view or edit selected files. The editor and browser utilities are customer configurable.
 * The delete function provides an option to bypass the OS/2 Undelete processing so as to not flush the OS/2 Undelete directory and to improve performance with mass delete operations.
 * The Wipe Files function has additional secure erase processing to better ensure nonrecoverability of files.
 * GtDisk
 * When appropriate, the checksums for HPFS volumes are automatically updated.
 * The Backup Boot Sector function allows for more comprehensive backup and restore for HPFS volumes. In addition to the logical boot record, the boot block, super block and spare blocks may be selectively restored in order to offer better recovery of corrupted HPFS volumes.
 * The HPFS Recovery provides easier use and additional recovery options. The remaining items in this section deal with the enhanced HPFS Recovery function.
 * The prompt mode can be changed on the fly for faster recovery operations requiring more or less manual intervention as desired.
 * Recovery of repartitioned disks even if the new partition does not correctly align with the old partition. In these cases, the customer is also informed regarding the difference.
 * Significant performance improvements during the analysis phase of the recovery operation.
 * The F-Node option allows specification of file F-Nodes as well as directory F-Nodes. An F-Node option has been provided which allows recovery of file data even if the entire directory structure of the disk has become obliterated.
 * Recovery enhancements for the HPFS386 driver supplied with the IBM LAN Server 4.0 product.
 * Warnings are issued when residual data resides on the volume from a previous format operation.
 * When possible, recovered files will have timestamps set to the values of the original file.
 * Error recovery has been added to prevent utility failure on badly corrupted volumes.
 * HexDump
 * HexDump allows you to convert binary files to ASCII readable text. The text is then viewable and editable using any standard text editor. You may examine the binary file in hex and ASCII formats.
 * The utility allows you to make changes to the hex or ASCII sections of the file and convert it back to binary format.
 * HpfsOpt
 * Optimization algorithms significantly enhance the effectiveness of file defragmentation and performance has been greatly improved.
 * This version fully supports the new HPFS 2.3 and 2.4 versions of the HPFS drivers including full support for permission (ACL) assignments found on the HPFS386 file systems supplied with the IBM LAN Server product.
 * Optimize
 * The Presentation Manager version of the HPFS Optimizer provides features which allow the customer to perform an analysis of the volume creating a list of files for optimization. The customer may then select or deselect files from the list and perform optimization on the desired files.
 * The progress of the optimization is shown by displaying messages in the main dialog window. The log file is still available for viewing and printing as desired.
 * Files selected for optimization may be selected by file size limits.
 * Optimization algorithms significantly enhance the effectiveness of file defragmentation and performance has been greatly improved.
 * This version fully supports HPFS 2.3 and 2.4 versions of the HPFS drivers including full support for permission (ACL) assignments found on the HPFS386 file systems supplied with the IBM LAN Server product.
 * The option to perform continuous optimization on one or more drives has been provided. The customer may select the volumes, trigger criteria and time intervals at which optimization is to be performed.
 * Reboot
 * Additional options to shutdown Presentation Manager applications and request that they save their settings prior to reboot.
 * SEdit
 * The editor displays known file system structures, such as the HPFS Super Block, in a formatted manner. Many of the HPFS and FAT file structures are supported. In addition, a feature is provided to format any disk sector as if it were one of the supported file system structures. And of course, you may view any sector in its hex/ASCII format.
 * A partition table edit feature
 * A FAT table edit feature
 * An editor command to compute and update the HPFS checksum values.
 * Multiple sectors may be written to or read from external files.
 * Sentry
 * Automatic detection of offline repartitioning of drives.
 * An option to automatically backup Config.Sys.
 * SysInfo
 * The GammaTech SysInfo utility displays serial (COM) and parallel I/O port assignments.
 * SysInfo displays the hardware IRQ assignments.
 * Undelete
 * When available, timestamps for deleted files on FAT volumes are displayed. In addition, when one of these files is undeleted, the undeleted file will have the same timestamp as the original.
 * The customer may mix and match the GammaTech Undelete with the OS/2 Undelete. When Undelete is executed against a volume where the OS/2 Undelete feature is enabled, the customer is given the choice of undeleting from the OS/2 Undelete directory or by using the GammaTech undelete procedure.
 * The list of deleted files shows the best guess for the path from which the deleted file belonged.
 * WipeFree
 * WipeFree is a command line utility to clear freespace on a disk volume. It replaces a similar feature in the old Delete utility. This version provides complete wiping of all freespace on a FAT or HPFS volume. As an option, a secure wipe can be performed which meets Department of Defense specifications.
 * Besides security issues, the WipeFree utility allows the customer to erase freespace on volumes which have been "fast formatted" . Fast formatted volumes retain data from previous formats of the volume which complicates recovery operations.
