Partition Logic 0.7

Partition Logic is a free hard disk partitioning and data management tool.

It can create, delete, format, defragment, resize, and move partitions and modify their attributes. It can copy entire hard disks from one to another.

Partition Logic is free software, based on the Visopsys operating system. It boots from a CD or floppy disk and runs as a standalone system, independent of your regular operating system. It is intended to become a free alternative to such commercial programs as Partition Magic, Drive Image, and Norton Ghost

Overview: This is a maintenance release, including a number of bug fixes and a significant re-engineering and modularization of the Partition Logic application, support for moving logical partitions and creating 'preceding' and out-of-order logical partitions, and the addition of new capabilities to the IDE disk driver including PCI, DMA (resulting in up to 700% performance improvement for raw disk I/O), and 48-bit addressing support (for disks larger than ~130GB).

What's New:

This is a major release. It offers an updated look and a number of new features, including 64-bit disk support, UDF (DVD) filesystem support, and GPT partition table support, as well as file browsing functionality. New administrative applications and functionality have been added, and the ATA/IDE driver has been enhanced, including the ability to better support backwards-compatible SATA controllers. A number of tweaks and bug fixes are also included.

• Added PCI, DMA, and 48-bit addressing support to the IDE disk driver.
• Did some touchups and corrections to the Visopsys I/O code in the libntfs (NTFS resizing) library.
• Implemented the ability to move logical partitions.
• Implemented the ability to create 'preceding' logical partitions.
• Modularized the Partition Logic application for better organization, and so that it will be better suited for working with different types of disk labels in future releases.
• Cleaned up new compilation warnings generated by GCC 4.1.1.
• Progress dialogs that show time remaining no longer zero-pad the values, and specify the time in "X hours X minutes" format.
• Fixed: The FAT filesystem driver's "get unused clusters" function was not properly returning an error if no free clusters were found.
• Fixed: Using the cursor keys in Partition Logic's disk list or partition list did not change the selection.
• Fixed: The kernel's GUID generation routine could hang because it was using an uninitialized lock structure. Sometimes resulted in a 'hang' during EXT filesystem formatting.
• Fixed: When creating a new logical partition in between two others, Partition Logic didn't set the disk order correctly.
• Fixed: IDE disk driver now properly checks for sector number overflow. Previously it could fail to detect attempts at >28-bit addressing, causing overflow at the ~130GB mark.
• Fixed: Lines of only whitespace in configuration files halted processing.
• Fixed: The progress dialog didn't layout properly when resized, and also fixed the layout of a few dialogs and windows vis. resizing.
