- This file gives list of versions of Partition saving with main evolutions.
-
- 1- V1.00 -> V2.00:
- 2- V2.00 -> V2.10:
- 3- V2.10 -> V2.20:
- 4- V2.20 -> V2.21:
- 5- V2.21 -> V2.22:
- 6- V2.22 -> V2.30:
- 7- V2.30 -> V2.40:
- 8- V2.40 -> V2.50:
- 9- V2.50 -> V2.60:
- 10- V2.60 -> V2.70:
- 11- V2.70 -> V2.80:
- 12- V2.80 -> V2.90:
- 13- V2.90 -> V2.91:
-
-
- 1- V1.00 -> V2.00
- -----------------
-
- Evolutions made are:
-
- - add of management of more than 8 Gb hard disk.
- - add of data compression.
- - add of several files saving capability.
- - interface change.
-
- Remark:
- -------
- All these modifications do that it is not possible to restore with V2.00
- version files created with V1.00 version (and reciprocally).
-
-
- 2- V2.00 -> V2.10
- -----------------
-
- Evolutions made are:
-
- - all language versions are into the same file with language recognition at
- beginning of execution.
- - some changes are made into interface: use of arrow keys to go from one
- element to another, add of arrows into scrollbar of listboxes.
- - add of mouse use.
- - add of batch mode.
- - add of deflate level choice (was to the maximum into previous version).
-
- Remark:
- -------
- All these modifications do not concern file format. So it is possible to use
- files created with version 2.00 (and version 2.00 could use file created with
- version 2.10).
-
-
- 3- V2.10 -> V2.20
- -----------------
-
- Evolutions made are:
-
- - add of possibility to save only occupied sectors for partitions with
- FAT12, FAT16, FAT32 (DOS/Windows) and ext2 (Linux) file system.
- - add of an option into batch file for this new possibility.
- - add of possibility to restore partitions from which only occupied sectors
- have been saved, on partitions with different size and that are on disk with
- different format.
- - add of copypart.exe util.
- - some change made into interface.
-
- Remark:
- -------
- This version is able to restore files created with previous versions (V2.00
- and V2.10).
- If all sectors of a partition are saved, created file format is not modified,
- so file could be restored with previous version program (V2.00 and V2.10).
- If only occupied sectors are saved, it is not possible to use this file with
- previous version of program (you will get an "Bad compression format" error).
-
-
- 4- V2.20 -> V2.21
- -----------------
-
- Evolutions made are:
-
- - correction of a problem due to that some CD readers/writers are identified
- as hard disk. Hard disk detection is now more restrictive (if somebody see
- that its hard disk is no more detected, please inform me).
- - correction of a bug for hard disk with standard access that have at least
- two logical partitions in the same extended partition. This bug does that
- partitions after the first logical one were not detected on V2.00 and V2.10
- versions and a "Page fault" error on V2.20 version.
- - correction in case of bad sectors: from 0 to 126 sectors following this
- bad one could be not read/written. Now they are.
- - add of "quit" and "reboot" options in options file in order to
- automatically exit program at end of execution and to reboot computer.
- - change of interface when asking for saving file name: now a second window
- gives you partition size and free space on each drive.
- - an estimation of remaining time is given in saving/restoring/copying
- window.
-
-
- 5- V2.21 -> V2.22
- -----------------
-
- Evolutions made are:
-
- - correction of hard disk detection in order to detect again some disks that
- were considered as CD-reader.
- - correction in the case a drive is not considered as a hard disk: following
- hard disks have a bad number.
- - correction of reboot.
- - add of window displaying search of last occupied sector in the case where
- only occupied sectors are saved.
- - add of a warning in case the file created/acceded is on the partition
- saved/restored.
-
- Remark: Evolutions made on hard disks detection for 2.21 and 2.22 versions
- could in some case do that an hard disk is not the same has the one in the
- saved file if this one has been created with a version preceding the 2.21 one.
- If only occupied sectors have been saved, this does not have any consequence,
- but in the case where all sectors have been saved, it could generate an "No
- partition agrees with one saved into file" error. In this case you have to use
- the version you have used to create the file.
-
-
- 6- V2.22 -> V2.30
- -----------------
-
- Evolutions made are:
-
- - a new correction on disk detection.
- - a correction on DOS drive letter attribution in case there was several
- main DOS partition on the same disk.
- - a new option to avoid check that created/read file is on partition
- saved/restored.
- - use of a new version of compiler and development environment that have
- better compatibility with Windows 2000 and XP.
- - availability to save only occupied sectors for NTFS partitions.
- - correction on free size on DOS drive when there was more than 2Gb of free
- space.
- - compatibility between partitions of the same type (partitions that have
- the same filesystem are considered as compatible).
- - if in batch mode, several files are needed when restoring and are on a
- removable media, program asks for next media in place of generating a "file
- not found" error and asking for next file.
- - changes into documentation and zip file structure.
- - some changes into GUI.
-
- Remark:
- -------
- This version is able to restore files created with previous versions. Reverse
- is true also, but not in case where only occupied sectors of NTFS partition
- were saved (using a previous version on such a file will return a "Bad
- filesystem format" error when opening file).
-
-
- 7- V2.30 -> V2.40
- -----------------
-
- Evolutions made are:
-
- - merge of the 3 programs into one and use of UPX (executable compressor) to
- reduce size. Add of window asking for action to do and of action options
- (-c|-d|-r|-s|-t).
- - add of console type user interface (-cui option) to solve some blocking
- problems on some computers.
- - correction of code to allow using batch mode when saving NTFS partitions.
- - changes in order to use copy of sector in case some FAT sectors are
- incorrect when saving only occupied sectors of FAT partition.
-
- Remark:
- -------
- This version is able to restore files created with previous versions. Reverse
- is true also. Nevertheless, if you have got some bad sectors when saving only
- occupied sectors of FAT partition, it is better to do this saving again with
- this version (as long as you do not change disk, previous saving will work,
- but the day you change your disk, it is possible that it does not work any
- more).
-
-
- 8- V2.40 -> V2.50
- -----------------
-
- Evolutions made are:
-
- - selected button is flanked by ">" and "<" to avoid potential confusion
- when only two buttons are displayed.
- - a driver is added to read saved file containing FAT partition from DOS as
- if it is a partition.
- - an option has been added to allow saving a FAT partition on itself.
- - batch file has been modified to take into account this new availability.
- - "reboot" option of batch file is also taked into account when saving.
- - ext3 partitions are taken into account as ext2 partitions if journal is
- created on the same partition.
-
- Remark:
- -------
- This version is able to restore files created with previous versions. Reverse
- is true also.
-
-
- 9- V2.50 -> V2.60
- -----------------
-
- Evolutions made are:
-
- - saving/restoring a whole disk, master boot record, first sectors of disk
- and partition table is available.
- - writing data on disk is always checked. That slow down restoring but
- allows to check that disk is not broken.
- - DOS drive detecting is modified such as network drive will be found again
- with some network drivers.
- - driver is corrected to avoid that computer hangs in case a program does
- not close all files that it used on simulated partition.
- - one of the paramaters of NTFS boot sector is modified in case a NTFS
- partition is restored on a partition which is not the same as the origin one
- (this parameter is said unused by Microsoft but is used during boot sequence).
- - add of a check that first chosen file could not have the same name than
- another file when using automatic naming to avoid it to be erased.
-
- Remark:
- -------
- This version could restore files created with previous versions. Reverse is
- true also, but not in case of saving disk, MBR, first sectors of disk or
- partition table (using a previous version on such a file will return a "Bad
- filesystem format" error when opening file). When disk use a standard access
- method, it could also occurs that files created with this version could not be
- restored with a previous version.
-
-
- 10- V2.60 -> V2.70
- ------------------
-
- Evolutions made are:
-
- - saving/restoring floppy disk is available.
- - saving/restoring DOS devices that could be accessed using sectors is
- available.
- - parts of code that use floating point unit have been modified to no more
- use if such as program could be used on 386 and 486SX that do not have a
- floating point unit.
- - in case a unexpected error appears, error message has more data such has I
- I could find where error comes from.
- - add of check that files are correctly written (by use of DOS VERIFY flag).
- - add of -nvd and -nvf options (and their equivalent into option file) to
- disable the check that sectors and files are correctly written.
-
- Remark:
- -------
- This version could restore files created with previous versions. Reverse is
- true also, but not in case of saving floppy disk or DOS device (using a
- previous version on such a file will return a "Bad support type" error when
- opening file).
-
-
- 11- V2.70 -> V2.80
- ------------------
-
- Evolutions made are:
-
- - for disk with extended access, use of standard access parameters when
- modifying boot sector of a FAT or NTFS partition instead of extended access
- parameters. This correction could explain why in some cases, running SYS.COM
- program is needed after restoring a FAT partition and why "NTLDR missing"
- message appears after restoring NTFS partition.
- - correction of an error when restoring partition table: not only partition
- table part of restored sectors is set, but also signature that signal it as a
- partition sector. This could avoid the good reading of partition table.
- - correction of an error when restoring NTFS partition on a partition with a
- different size: size of file telling which sectors are occupied was updated
- only at one place, when it is present at 2 places. This seemed to have no
- influence on Windows behaviour.
- - add of -bui option that allows having an user interface similar to the
- default one but with a better compatibility. Counterpart it is slower.
- - add of -cm and -pm options to have two way to use mouse: -cm is the
- default one and use a specific function of mouse driver (function that could
- not be present), -pm use a method with a better compatibility but that could
- miss some double click events (it is the default method for Windows NT/XP).
-
- Remark:
- -------
- This version could restore files created with previous versions. Reverse is
- true also.
- Because of the first correction, restoring partition could appear as different
- as origin one even if it is the same. In this case and if you have saved all
- sectors (and so no partition will match), you will be obliged to use the same
- version as the one you use for saving. If you have saved only occupied
- sectors, there will be theorically no differences.
-
-
- 12- V2.80 -> V2.90
- ------------------
-
- Evolutions made are:
-
- - modifying Windows 2000/XP registry to update partition definition when a
- partition is moved is available.
- - modifying the BOOTSECT.DOS file to update it when a bootable partition
- used into Windows XP multiboot is moved is available.
- - a correction when restoring a NTFS partition on a partition with another
- size to update size of file listing bad clusters. The fact that this file does
- not have a correct size previously seems to have no consequence on filesystem.
- Warning: only size is updated, file is not modified to reflect bad clusters in
- more or less.
- - add of "automatic_naming" option into option file that allows getting
- automatic naming when using option file.
- - add of use of environment variable into option file.
- - maximum filesize could now be given in kb if free space on drive is less
- than 10 Mb. This case could be useful to save small elements (MBR, partition
- table) on floppy disk. Option file is modified to be able to add unit of size
- (in Mb as default).
- - change of a parameter into file header when saving a floppy disk to set it
- compatible with driver use. This parameter is only used in this case, so
- compatibility is insured with file created with previous versions for others
- program options.
-
- Remark:
- -------
- This version could restore files created with previous versions. Reverse is
- true also.
- Because of adding environment variable use into option file, if an old option
- file has a '%' into an option, it could be incorrectly read (you have to
- double the '%' to get it working).
-
-
- 13- V2.90 -> V2.91
- ------------------
-
- Evolutions made are:
-
- - support of very fragmented NTFS partitions. These partitions can now be
- saved with saving occupied only sectors when the whole partition should be
- saved before.
- - change of update of backup descriptor sectors on ext2 partitions. Update
- is now done with using original sector definition instead of their own
- definition because it seems not to be updated when using partition.
- - change into interface when updating registry entries for the ask of driver
- lettre to set to chosen partition. Instead of having to give the drive letter,
- program shows you list of drive letter it could modify.
- - a correction to avoid option file creation to be asked when doing a save
- with an option file using the "automatic_naming" option.
-
- Remark:
- -------
- This version could restore files created with previous versions. Reverse is
- true also. But in case of very fragmented NTFS partition, it is obvious that
- previous version will not be able to restore file created with this version.
- It is also to be noticed that you could get a little difference on file size
- between this version and previous one when saving NTFS partition, this is not
- a problem and does not disallow file compatibility.
