Partition Logic 0.71
Version warning Има по-нова стабилна версия на тази програма.

Описание

Partition Logic е безплатна програма за работа с твърди дискове и техните дялове. С нейна помощ можете да създавате, премествате, форматирате, конвертирате, оразмеряване и изтривате различни дялове на твърдите си дискове, а освен това да копирате цялото съдържание на един диск върху друг. Програмата е изградена на базата на изцяло независима операционна система и се стартира от CD-ROM, без да изисква наличието на друга операционна система. Според авторите това е доста реален конкурент на скъпо платените Partition Magic, Drive Image и Norton Ghost.

Технически данни

  • Implemented USB booting.
  • Added a USB blank-image file and a script for installing into it.
  • Improved detection of USB devices by always separating hotplug behaviour from coldplug detection at boot time.
  • USB 2.0 (EHCI) controllers are detected and disabled (reset) so that they don't interfere with access to the legacy USB 1.1 UHCI ports.
  • Search all 255 possible PCI buses, not just the first 10. It's slower to search them all, but some devices have been seen to reside on e.g. the 17th bus.
  • Improved recognition of PCI device classes and subclasses.
  • Added support for multiple buses of any type (such as PCI and USB)
  • Implemented a partial ACPI power management driver, so that the shutdown command can power off the system.
  • Updated GPT GUIDs for partition types, and moved the definitions and descriptions into the header file src/include/sys/guid.h
  • The boot menu installer now shows a warning that Windows 7 (and maybe Vista) will require the installation CD, in order to 'repair' its boot configuration.
  • The OS loader now passes a boot sector 'signature' found on the boot device (such as in the MBR) to the kernel in order to help the kernel figure out for itself which device it should mount as the root filesystem.
  • We now mark the logical disks of non-partitioned physical disks as being 'primary' partitions.
  • The kernel's disk management code now recycles disk numbers, so that for example, inserting a USB stick which gets named sd0, then removing it and reinserting, doesn't result in the disk being named sd1
  • Reformatted the output of the disks command.
  • The EXT 2/3 driver can now mount filesystems with variable-sized inode structures.
  • The filesystem 'resize constraints' call (such as to the kernel or NTFS) now passes a 'progress' parameter just like a real resize, so that error messages, etc., can be presented to the user.
  • Fixed: USB endpoint enumeration no longer discards the 0x80 bit of the endpoint address, since some devices require it in order for the endpoint address to be unique.
  • Fixed: A number of USB sticks would fail to enumerate, because port reset timings/logic were not technically correct.
  • Fixed: Pulling a USB stick that hadn't been successfully configured by the SCSI USB code would cause the USB thread to page fault in kernelDeviceHotplug().
  • Fixed: An EXT 2/3 symbolic link was showing up as an empty icon in the file browser.
  • Fixed: FAT volume label entries stored in the root directory were not being re-created when the directories were written.
  • Fixed: The kernel's GPT partition table code was not correctly reading partition table entries; it was failing to correctly calculate the buffer size and number of sectors of the entries.
  • Fixed: The Disk Manager program was incorrectly calculating the ending sector of entries in GPT partition tables.
