RMPrepUSB Version History

v1.9.70 download also includes the extra standalone RMBootSect and RMFormat utilities which are not used by RMPrepUSB or RMPartUSB (the other downloads do not include these two utilities).
v1.9.75 - added randomised disk signature and patched boot code for better compatibility.
v2.0.602:
FORCELBA option and Format as USB-FDD (large floppy) function. (512MB ZIP radio button removed)
USBtoFile and FiletoUSB image functions added. USBInfo and FileInfo (displays bytes and partition info).
QuickTest USB Drive for bad/duplicate blocks - use on new USB drives bought from dodgy eBay sellers!
Extensive context sensitive help added and PDF help file.
Uses MiB rather than MB.
Includes Vista manifests to run with admin rights and FreeDos boot files.
v2.0.710/2.0.720/2.0.730
Added syslinux and grub support
Desktop now minimized and restored to prevent file copy and cmd windows being obscured.
Quicktest improved - now suggests maximum usable good memory. Tests 1GiB in 4 seconds.
To quicktest a Flash drive
1. Run Quicktest (if you get write errors CLEAN the drive first and try again)
2. If it suggests a usable size of say 1098MiB, then reformat using RMPrepUSB to 1098Mib size
3. Now test with H2TESTW to ensure all bytes are readable in the volume.
If you re-partition the drive, remember to set the size to the 'good' size.
Also remember that the memory may develop bad blocks with age!
v710 replaced with v720 as NTFS format in 710 was unreliable.
v720 replaced with v730 (fixed fat32 format hanging bug on large >16GB drives, fix NTFS format sometimes reports errors, GUI improved + 1-6 steps numbered, improved volume locking and speed. Lots of small GUI tweaks.
v2.0.733 includes support for BartPE (PEtoUSB type function).
Two steps to make BartPE:
1. Use PE-Builder.
2. Use RMPrepUSB - you can have FAT16, FAT32 (any size) or NTFS.
Also added improved syslinux options and force-mba-test grubinst cmd line parameter added. Looks for up to 26 drives.
Only called 'Beta' as PEtoUSB function is new.
v2.0.734- few small bug fixes around BartPE function when cancelling, etc., removed winbom.ini file, new PDF help file.
v2.0.735
Include the TESTMBR files and instructions on how to use them

v2.1.506 - USB drive detection improved yet again! German language support+pdf added. RMPREPUSBXP.CMD for BartPE now run a language version (e.g. RMPrepUSBxp_German.cmd if German selected as language). Now near to final release.
v2.1.507 - Small bugfix, USBtoFile if length=0 entered now uses DALL instead of PALL.
v2.1.600 - 8 October 2010 - Release version. Small text change in RMPartUSB.
v2.1.601 - Beta - New RMPrepUSB.ini file feature added. You can now store your favourite configurations in an ini file and load them when RMPrepUSB first runs.
v2.1.602 - Beta - Small bugfix if no ini file and click on Prepare Drive.
v2.1.603 - graphics bits around checkboxes removed. Language box font changed, syslinux options in ini file
v2.1.604 - detects locale and sets as default (syslinux 4.03 now used), Ext2 using mke2fs added.
v2.1.605 - syslinux button added + INI file has 'make specific button invisible' options
v2.1.606 - new homebrew version of grubinst.exe to fix MS-DOS boot issue when grub4dos installed to the PBR. Installing grub4dos to PBR on NTFS partitions now works. Latest chenall version 0.4.5b of grldr used. Dutch language support added.
v2.1.606a - newer version of grubinst.exe to fix boot bug on Acer laptops when installing grub4dos code to MBR See here for details (also includes MS-DOS PBR bug fix in 606 version).
v2.1.607 - Partition type numbers for FAT16/FAT32 changed for better compatibility 06/0E and 0B/0C for FAT16 and FAT32 CHS/ForceLBA respectively. Start CHS parameters not changed when ForceLBA used. More compatible with Dell systems (and possibly others).
v2.1.608 - Some GUI features improved thanks to feedback from TheK of Reboot-pro. Syslinux 'stupid' question removed. Bold font in INI file now only affects help text. Syslinux folder included so user can copy the version they want to use to the RMPrepUSB main folder (3.86, 4.01 or 4.03). 'Lite' version now available which reduces size of download.
v2.1.608a - grubinst.exe version changed back to that used in v606. The code change in grubinst Acer fix v2.1.606a does not work in some cases and is unreliable/bad code.
v2.1.608b - new version of grubinst with both code changes in.
v2.1.609NOWMI - Experimental and not fully tested version which does not use WMI calls (except for listing OS in CSV file of speed test results). This appears to work fine under Hirens PE except that the drive is not remounted by the OS after partitioning and formatting. This means that the copy files process fails after a format because the new volume is not automatically remounted by the OS. It should work under WinPE v2/v3 however. Please report any bugs (not fully tested yet by me so there will probably be some!).
2.1.610 BUG - still tests for RICHTX32! - removed dependency on RICHTX32.OCX and WMI support. Includes a fix to remount a formatted drive when used under Hirens Boot CD - it calls ShowDrive.exe which must be present in either the RMPrepUSB folder or a pathed folder (e.g. \Windows\System32) to remount drives after partitioning and formatting. Thanks to TheK for the programming tips!2.1.610a BUG - still tests for RICHTX32! - as 2.1.610 but includes showdrive.exe in the download.
2.1.611 - BUG IN NTFS FORMAT IN RMPARTUSB - the test for RICHTX32.OCX being installed is now removed! So no dependency on RICHTX32.OCX (honest!).
2.1.612 - Fixed bug in NTFS FORMAT - volume lock was not working correctly (new non-wmi code now fixed).
2.1.613 - all features tested and checked. More support for hirens/bartPE. surplus code removed. No msvbvm60.dll now as should already be in OS (full version of RMPrepUSb installer has it in a DLL folder in case you need it).
2.1.614 - Function hotkeys added. Many bugfixes. If use config file, it will autorun grubinst or ext2 FS without needing to prompt user. 2 days spent on snagging and testing. Seems pretty solid (not done much testing on Bart/Hirens though!).
2.1.614a - bug in 614 (only a few downloads were done in about an hour) - if you have no rmprepusb.ini file it always prompted you to run grubinst and exe2 FS after a format! Fixed in 614a.
2.1.615 - added ability to specify .\xxx in RMPrepUSB.ini to reference a folder under the RMPrepUSB.exe folder.
2.1.616 - added F12 = present user config menu again. RMPartUSB command line FIND bugfix (echo'd command line). Also Drive string when echo'd has 0 byte chars from some drives.
2.1.616a - small bugfix to speedtest - model and size not saved to csv file. RMPartUSB 2.1.617.
2.1.617 - TESTMBR code in folder re-written. Some 'sleep' delays removed to speed up the process!

2.1.623 New grub4dos version which treats text after ## in any menu as a comment so you can add comments to each line. RMPartUSB FAT16 NTLDR/Bootmgr MBR code tweaked for better compatibility. Syslinux 4.04 now default version and other versions added to syslinux folder.
2.1.625 Added QEMU button, set form focus after Prepare, qemu-img used to convert filetousb images to raw, warn user if drive=0 selected, Alt+F5 toggles ALLDRIVES setting so you can use it on hard drives too. Some versions of Syslinux removed from Syslinux folder. New QEMU version used. Improve FAT16/FAT32 bootability by using LBA type B/C partition types always (was only when Force LBA was used previously).
2.1.625a Replaced new qemu-img v0.15.0 with old one 0.11.0 as new one cannot convert large vdi files to raw format (bug in new qemu-img)
2.1.626 - 15-08-2011 - New grub4dos version (recognises ' # ' or '## ' as in-line comment tags), small changes to FiletoUSB and QEMU button now grey not blue.

When you click on the Choose Copy Folder button, you can now choose either a folder OR an archive file to extract from (e.g. ISO,CAB,IMG,VHD,LZH,GZIP,IMA). Then instead of copying files from a folder after it has formatted the drive, it will extract the files from the chosen archive file instead.
