(Disk and filesystem browser for OS/2 and Windows NT)

 Hi Folks.
DFSee has been updated by Jan van Wijk to version 3.18 and I tested it on my Warp 4 FP12 OS/2 Client. At this time, March 13, 2000, a new version of DFsee is available for download in the developers web site: DFSee version 3.20 (dfsee.zip, 772KB) and Im just testing it. (In the V. 3.20, new -q and -b options DFSee now supports a '-b' option for batch, and '-q' option for quiet mode VRAID, the OS/2 software raid by Vitus Jensen, is now recognized).I'm testing DFSee since the first version and I verified that the atual release is really the ultimate tool for accurate disk information and maintenance. I'm using DFSee here on Warp 4 FP12 called by Control + Alt + Del Commander from Perez Computing Services: I dropped the DFS object in my WPS into the CAD Commander Control Panel and I call Dfsee by Ctrl + Alt + D as you can see in the photo below:

You can download DFSee here and from Hobbes (dfsee318.zip, 772KB). DFSee is a precision tool for OS/2 Warp and Windows NT and if you are a professional you simply cant live without it. Note that this fantastic tool is free. If you know the problems that exist in OS/2 Fdisk and NT Disk Administrator; if you use Linux Fdisk, DOS Fdisk, Windows 95/98 Fdisk or Pdisk by PowerBoot, you need DFSee. With DFSee you can obtain the precise information and solve all problems. In the photo below you can see the DFSee Fdisk running on my Beta Test Special Machine where I works with Windows NT4 SP6 on a HDD master connected in the first IDE and with OS/2 Warp 4 FP12 on another HDD also master connected in the second IDE:

The DFSee program is a disk and filesystem browser with an emphasis on the HPFS and FAT filesystems, disk partitioning and some NTFS. FDISK, file-system display & analysis. Shows partition-tables and bootsectors. Shows HPFS/NTFS/FAT disk structures like Superblock, Fnodes, Dirblocks etc. Check allocation integrity for volume. Can find any data-sequence on the disk and identify the file it belongs to. Display allocation maps for the disk and for the directory-band. Includes CHKDSK UNDELETE/copy functionality for HPFS It will support different file-systems sometime in the future.

The program has been built while studying the HPFS filesystem. It's main purpose is getting to understand the file-system as it resides on the disk itself, in the data-structures laid down in disk-sectors.

Over time, additional logic was implemented to allow analysis of all sorts of disk problems on HPFS volumes. The tool has been used a few times over the past years to analyze some real-life disk problems in a large systems-integration project.

Also it has proven very useful in teaching others the internals of HPFS Most of my knowledge of the HPFS file-system is based on the excellent lectures "HPFS Internals" at the 1994, 95 and 96 ColoradOS/2 conferences by Doug Azzarito and on peeking around on a lot of HPFS volumes using DFS.

Further improvements will probably be in more advanced recovery commands and other filesystems like NTFS and EXT2 and in porting to other platforms.

The standard distribution, DFSeexxx.ZIP contains executables for OS/2 Warp (32-bit), 16-bit DOS and Windows-NT.

Photo above shows DFSee reporting all volumes in both HDDs of @Macarlo's Beta Test Machine

WARNING: Partitions created by DFSee versions 3.16 and 3.17 might have slightly non-standard sizes and boundaries. Due to a bug introduced in 3.16, the partition (or extended partition container) can end on a head-nr that is one less than intended. For logical partitions this can lead to unusable free-space after the partition.

Recovery: Just delete the affected partition(s) with DFSee, and create them again in the same place, the same order and with EXACTLY the same size as before. This will keep the data inside the partitions intact.

In the photo above DFSee shows all partitions descriptions of @Macarlo's Beta Test Machine

DFSee have an extense and supercomplete description for use it correctly, with all commands, all options. Get the file, install it an see by yourself. To install DFSee simple create a directory such DFSee318 and unzip into this directory the dfsee318.zip; to run this tool simple click the exe on your WPS or Windows desktop or simply call for it into a command line: DFS. That is all!
