Arca Noae announces GUID for OS/2 Type 1 GPT partitions

In our last post concerning GPT in ArcaOS, we discussed the first phase of support and how our specification allows for multiple partitions up to 2TB in size. As every GUID (Globally Unique Identifier) partition type requires a GUID, we have set:

90B6FF38-B98F-4358-A21F-48F35B4A8AD3

as the GUID for OS/2 Type 1 partitions.

Any GPT partition using this GUID should ultimately be recognizable by any GPT-aware operating system as belonging to ArcaOS.

Although this is now just a simple proclamation, it is, in point of fact, a major advancement for the platform, and sets the stage for our initial GPT support, currently planned for release with ArcaOS 5.1 in 2021.

Arca Noae makes no guaranty as to availability of GPT support for ArcaOS 5.1. When available, GPT support will be an ArcaOS feature only, with no plans to make the technology available for other OS/2 distributions.

Don’t have ArcaOS yet? Now is a great time to pick up a license or two and replace those aging Warp 4 or eComStation installations and get to know what’s new and improved. If you’ve never run OS/2 before, you’ll be amazed. If you last used OS/2 in the 1990’s, you’ll be even more amazed. ArcaOS runs the vast majority of existing OS/2 Warp 4 software, because it really is OS/2 – just better. ArcaOS supports more modern hardware than any other OS/2 distribution available today, making hardware upgrades much easier than ever before. An ArcaOS 5.0 license now means steep discounts on future upgrades, including 5.1.

Arca Noae’s plan for supporting GPT disk layouts in ArcaOS

Through the release of ArcaOS 5.0.6, all OS/2 distributions have only supported MBR (Master Boot Record) partitioning schemes, that is, up to four partitions on a disk, with the possibility of creating multiple logical volumes in one extended partition. This partitioning scheme is also limited to a maximum of 2TB per disk.

The GPT (GUID Partition Table) breaks out of these restrictions by supporting an almost unlimited number of partitions (without the need for logical volumes) and disks exceeding 2TB.

Supporting GPT is another major step for multiboot configurations where the disk has already been partitioned using this style, which will allow ArcaOS to install alongside other GPT-aware operating systems (Windows 10, modern Linux distros, etc.), without the need to install a second MBR-partitioned disk or to wipe, re-partition, and reformat all volumes on the existing disk.

Arca Noae’s approach to supporting GPT will be multi-phased, with the first phase of development currently underway and anticipated for release with ArcaOS 5.1. The design specification of our initial GPT support is to allow for partitions up to the current 2TB maximum size, with multiple partitions of this size possible on disks larger than 2TB. Our specification further provides that ArcaOS be able to create, delete, and modify GPT partitions which are identified by their GUIDs as being “OS/2-type” partitions, and lastly, that GPT support be available for both traditional BIOS (for data volumes) and UEFI-based systems (for boot and data volumes).

Arca Noae makes no guaranty as to availability of GPT support for ArcaOS 5.1. When available, GPT support will be an ArcaOS feature only, with no plans to make the technology available for other OS/2 distributions.

DFSee 16

DFSee MAJOR version 16.0 released

In case anyone missed this in the news outlets, here is an abbreviated version of the official DFSee 16.0 release announcement:

DFSee version 16.0 has been released, with significant new functionality and fixes.

It is a MAJOR release, introducing TWO new filesystems with full support including file browsing and recovery, bringing the total number of supported filesystems to around 10!

The new filesystems are:

ISO – The ISO9660 filesystem as used on CDROM’s and DVD media, and perhaps more importantly in .ISO imagefiles representing them.

You can now use DFSee to copy files from a CD/DVD or ISO image.

The Rock-Ridge (Unix/Linux) and Jolliet (Windows long names) extensions are supported as well, selectable where needed.

APFS – The new Apple filesystem, used in iOS and newer macOS versions (High Sierra, Mojave) that moves up a lot of the filesystem limits from the older HFS+ and is optimized for SSD storage.

APFS supports multiple independent volumes in one partition, all sharing the same pool of storage blocks (container), and it is organized using B-trees for almost everything, making access to information really fast.

The APFS support has all the familiar DFSee analysis functions and also supports browsing and file-recovery for normal files. (XATTR and Resource-fork support will be coming soon).

There have also been some improvements in the menu-system like attached submenus to select a partition for PTEdit or LVM, to select an APFS volume from a container or to select between Standard, Jolliet or El-Torito areas within an ISO.

Of course, as usual, there are also many smaller improvements and bug fixes.

This being a major release, it will require an upgrade if you currently have a registration for an older version, so visit the DFSee product page in the ArcaOS store to purchase an upgrade at a great price.

Note: Keys sold on or after January 1, 2019 are valid for version 16.x, with no additional upgrade required.

DFSee version 13

Checked your disk lately?

Mysterious boot problems can be caused by a variety of things from failing hardware to software misconfiguration. Besides regular file backups, saving your disk partitioning can be a big help during recovery (or reconstruction onto a new drive). Fixing an odd problem, such as the once-in-a-lifetime file with an impossible character in the name which just won’t delete, is also possible with a good disk tool. Moving to a new disk to gain more space? You’ll need something to carve that room into something useful and transfer your data.

Luckily, we have just the thing: DFSee, the Swiss Army knife of disk utilities. DFSee runs on a variety of platforms, so if you need to boot from “something else” to fix your OS/2 system, you may. (Likewise, you may boot from OS/2 or eCS to fix your other OS.)

DFSee, now at version 13, now has full support for GPT partitioning schemes, compatible with current systems on the market today. It has an amazing array of features, including:

  • View, analyze, edit and fix partition tables
  • Support for GPT partitioning schemes (as mentioned above), including move, copy, and resize
  • Browse, analyze and fix various filesystems
  • Undelete files
  • Replacement for FDISK and LVM (Logical Volume Manager) tools
  • Clone, backup and restore partitions or filesystems
  • Split large images in smaller pieces suitable for burning to CD or DVD
  • Hex editor
  • Scriptable recovery

and, of course, that world-famous support from the developer, Jan van Wijk and Fsys Software.

Bootable media DFSee is installable to a local partition or may be run from a bootable CD or USB stick, which makes it especially handy for real rescue operations.

If you’ve never licensed a copy of DFSee, now is the time to do so. If you have an older version (even a very old version), an upgrade is only a few clicks away, and if you have a license for version 12, we have an even better deal on an upgrade.

Don’t wait until it’s too late. Review the full feature list at DFSee.com, and stop into our store to license your copy today.
