To gain physical access to a hard drive at the sector level with dd.exe, you have to be administrator. The same applies to 7ZIP parsing the disk at the sector level. In this picture, you can see this EXT4 partition opened. \\.\PhysicalDrive2\2.img\ https://i.postimg.cc/Hxq3pkK1/7_ZIP_...inistrator.gif The speed with which it opens a partition, varies a lot. This capability might have existed in 16.04, but the program seemed to be pulling structure into RAM rather than using its usual stream-like semantics. This could exhaust the machine to the point of freezing it. Don't wait too long to do something about it :-) If the program won't "cancel" when you cancel the operation, reach for the hammer in Task Manager and aim for 7zFM. Paul |

It is something peculiar to 7zip, Windows Explorer refuses to take seriously \\.\PhysicalDrive0\. When you manage to assign a letter to a Linux partition via ext2fsd or otherwise, you can access the ext-partition from any file manager under Windows. frank That technology is called "Installable File System" or IFS. It allows Windows to understand a foreign file system, by installing a file system driver for it. And because it "converts" the foreign file system to look like a local file system, you can assign a drive letter, do reads and writes and so on. The 7ZIP capability still uses a file system driver (of sorts), but the file system is not mounted and only exists in the 7ZIP window. Since 7ZIP loves to set up multi-layer streaming "extractions", it takes time to collect the information it needs during its mounting/parsing phase. When it opens regular archives, this operation can be "fast" because the archive has a file table down at the end. Since source isn't available for the versions of 7ZIP we use, it's hard to say what the code is doing when it takes so long. But rest assured the developer keeps playing with that code, because the behavior changes with release number. Paul |

Hi Paul, It's more pernicious than just the version, but I'm not at all worried about the problem since it has been confirmed by reliable people that 7-Zip works fine to read dual-boot Linux disks. I got 7-zip to work to read the Linux disk, but then I kept getting a conflict error when I tried to write up and screenshot and document the steps for everyone to benefit (as I normally do). Even after multiple reboots, I got those conflicts, so I just deleted everything that I had installed and I'll start fresh - but - I want to be clear - I'm not at all worried since I'm sure it's not normal to be accessing the linux disks from so many concurrent ext3 readers simultaneously. The other possibility, is there's something wrong with the EXT4 file system and maybe it needs an FSCK. Don't forget that some Linux distros shut down "in a hurry" without dismounting the root file system properly. They do this, because they know the journal and a "clean" operation at boot, will fix the mess. I'm using Windows 10 and Ubuntu 18.04 precisely because that's what most people use, where I _could_ have corrupted the ext3 filesystem during my experiements over the course of a day or so. Again, I'm not at all worried about that, as the main reason for this thread has been accomplished, which was, and is always... 1. To disseminate my knowledge, and, 2. To learn from all your knowledge. That way, we're all more powerful together, than we are alone. I think this thread accomplished that main set of goals. Thank you all, for suggesting the highly non-intuitive solution of 7-zip, which, once you know the tricks, is fantastic I'm sure! |

news alt.comp.freeware, wrote: I dual boot Windows/Ubuntu because Ubuntu 18.04 natively provides simultaneous full and complete read and write access to the entire visible file system of Windows, Android, and iOS. You should not be using Linux to write to an NTFS file system if you can avoid doing so...It's best to let Windows manage it's own file system as far as writes are concerned. However, I'm mostly on Windows, where, unfortunately, Windows natively will NOT read the default Linux file system (neither will the Mac). Windows won't out of the box, no. But, you have options to give it that functionality. I strongly recommend that you ONLY use it for READING your NTFS partitions while under linux. NOT writing to them, unless you have no other choice. As in, you forgot your windows password and aren't comfortable editing the sam file yourself to void the password and let you back into your machine. The NTFS file system has gone through revisions throughout the years and it's a closed source proprietary file system. Any access to it, reading and/or writing by 3rd party apps not officially licensed by Microsoft is done via reverse engineering efforts alone. No, having the leaked source code to windows 2000 will not help you write a universal linux based ntfs partition read/writing driver. Windows 2000 NTFS and Windows XP for example ARE different. Vista and up is that much more. Thanks to Aragorn on the Linux newsgroup, I found out today that both Windows and the Mac will easily read/write the Linux native filesystem if you load free software to do so (some of which is even open source). To that end, today I quickly tested these Windows solutions below: 1. https://sourceforge.net/projects/ext2read/ 2. https://sourceforge.net/projects/ext2fsd/files/Ext2fsd/0.69/ 3. https://www.diskinternals.com/linux-reader/ How long have you been using computers did you say? Specifically, I downloaded, extracted & ran these 3 executables: 1. https://sourceforge.net/projects/ext2read/files/latest/download 2. https://sourceforge.net/projects/ext2fsd/files/latest/download 3. https://www.diskinternals.com/download/Linux_Reader.exe Here is my initial first-pass quick-test assessment, for your benefit, of those three solutions, where I ask anyone with *experience* using any of these three programs to access their dual-boot Linux partitions, to further our combined tribal knowledge. I have extensive experience using them along with my own custom written software....Primarily developed to assist in data recovery for NTFS based file systems. *ext2fsd* This automatically creates a drive letter for your Linux filesystem. The GUI was kind of miserable (e.g., it wouldn't even resize properly). I'm sure it can do the stated task, but it has a steep learning curve. Define steep? *LinuxReader* I kind of like the GUI of the last one the best, at least upon 1st use. It presents your Linux and Windows disks in a familiar "My Computer" style. When you want to copy a file from Linux to Windows, you just hit "Save". You'd be better off using another drive, formatted in an OS universal friendly file system, say fat32. and swap your files between those OSEs using that. Instead of placing your NTFS file system in harms way each time you issue a write command do it from outside of Windows. Really, all joking aside, ask some other tech background people (especially data recovery experts) the game of russian roulette your not only playing by writing to your NTFS partition(s) under linux, but encouraging others to do so. Let Windows manage NTFS, Don't expect that of Linux. It'll do it's best, but it could cost you everything on the NTFS partition if (a) you don't have reliable backups and (b) know next to nothing of file systems internal structures (Based on your usenet posts so far, it's a safe bet you couldn't rebuild a wrecked NTFS file system without considerable hand holding and software recommendations.) Since the price of freeware is the effort it takes to find the best ones, my quick test clearly indicates I should likely first spend my learning efforts on the "LinuxReader" and to ditch the other two (unless there's a reason I learn later to do otherwise). Are you using these newsgroups as your own personal playground to bounce ideas around or something? You chastise and ridicule various posters when you ask for their advice/help, yet, act like such a ****ing n00b with posts like this one. Not only n00b attitude, but very BAD advice being offered. For those who aren't as dumb as Arlen and know a thing or two about that box sitting in front of them, please, if you care about the data on your Windows partition(s), don't issue very many write commands to them from any particular Linux distro. You should write very conservatively outside of Windows and ONLY when necessary. Otherwise, let Windows write to it's own file system. If you feel you must be able to share between both, since you're dual booting. Create a fat32 partition. They can both, SAFELY read and write to it without presenting any risk to the data on it or other partitions.

news alt.comp.freeware, wrote: The "problem" with LinuxReader might be that it's apparently read only. That's NOT a problem. The author of the program knows how risky it is to perform writes of any kind on NTFS... You have to understand that NTFS isn't public/open source. Documentation on it is sketcky on a good day. Those who have reliable docs are under an NDA. Any drivers you find on linux that can read and or write to NTFS is due entirely to 3rd party reverse engineering efforts. Reverse engineering isn't perfect. Some things can be missed. Changes in the NTFS file system are known to occur from time to time. Some are larger than others, but, any is enough to make a driver unsafe to use for writing. XP and Vista for example are not using the same version of NTFS. I also found Paragon payware, where they seem to be the go-to guys for commercial solutions on both Windows & the Mac: https://www.paragon-software.com/business/extfs-for-windows/ I can highly recommend their apps if you have a serious need for their usage. They aren't relying on 3rd party reverse engineering efforts to read or write NTFS. They have MS documentation and their blessing. As you're all well aware, the expense of freeware is almost all in the choosing of the best ones, so my "added value" to the team is simply those initial insights - where I ask for more insight from experienced users. That isn't always the only expense. Depending on the value of data that can be lost from using freeware (or payware for that matter) might supersede it's value. However, my weapon of choice to READ (not write!) ext/2/3/4 is 7-Zip. Both the command line program (7z.exe) and the 7z file manager (7zFM.exe) support full read access to physical drives (and files) in ext2/3/4 format. I've never seen the need to use any other tool for that purpose. And I would never use a Windows app to WRITE to an ext2/3/4 file system. Wow! That's a neat idea, if it works! It does. You'll notice, they specifically (like myself) do NOT encourage the use of ANY linux based software to WRITE to any NTFS based file system. There IS a valid reason for that. Thank you for potentially furthering our knowledge. I already had 7Zip so I brought up the GUI, but it's not obvious to me what's the first step after bringing up 7Zip on Windows to access a foreign file system such as the dual-boot Linux partition is: http://www.bild.me/bild.php?file=56940667zip.png You keep using our/we, etc.. Do you have a turd in your pocket or something? On this thread, I haven't seen you contribute tribal knowledge (wtf is that exactly?). I've seen various others share (except for 7zip, I'll give you that's probably not completely common knowledge, but it is mentioned in their faq; if anybody reads those (I do) what I consider to be common knowledge and vary sound advice. Can you give us a hint as to the next step in 7Zip to access the Linux partitions under a typical dual-boot of Windows 10 and Ubuntu 18.04? Is google broken? What exactly are you calling a typical dual boot configuration? I'll give you a cluebyfour for free, no charge. not even shipping and handling; there's no such thing. Each one is going to be a little different, based on internal hardware and drive geometry differences. Not to mention user choice when it comes to kernel selection on Ubuntu. I'll let you slide on those pesky details because I haven't seen you claim to be anything more than a power level end user.
