Re: Raid 5 With Windows 10
Angie Troia
I am a new Ubuntu user with a fresh installation, and am eager to get started with it. However, all of my important data is on Windows software RAID 0 array, and I need it to stay there as I'm also dual booting Windows. I need access to this data on Ubuntu, and can't really get anything real done until I have access.
I have not tried following these instructions yet. Why? The post includes a warning about how you must not write to it if you enter the wrong chunk size; it's understandable how that could cause problems. My concern is that my setup is different to their example, and I am not sure that the commands should be entered exactly the same for my setup. I am afraid to break it by doing it wrong, and therefore wish to get the advice of somebody more experienced.
I hope I've provided enough information here. So now, my question is this: what is the proper command for me to enter with my setup, so that I can access both of my Windows RAID 0 partitions from Ubuntu?
It was extremely difficult to uncover this elusive information. It took days of searching, and I guess I wasn't finding it because the post makes no mention of RAID, so it wasn't coming up in my search results. It definitely works for my Windows software RAID 0, though.
The solution is actually quite simple. There's a wonderful tool built specifically for this purpose, called ldmtool. It is capable of reading and working with Windows dynamic disks which use LDM (Logical Disk Manager). It is not installed by default, but is included in the Ubuntu repositories. All I had to do was execute two commands:
The first command installs ldmtool, and the second has it automagically create device mappings for all of the connected Windows dynamic disks. These mappings are located in /dev/mapper/ and can be mounted manually with mount -t ntfs /dev/mapper/mapfilename, but I didn't need to do that - Ubuntu mounted them for me automatically after I ran the above two commands. That's all I had to do, and I could immediately access them from the file browser!
The linked post includes a suggestion for doing this automatically every boot. Just open the file /etc/init/mountall.conf and add the line [ -x /usr/bin/ldmtool ] && ldmtool create all >/dev/null true immediately before the exec mountall ... line near the end of the file.
It isn't necessary to run the above commands, as ldmtool create all does all the necessary work to create the mappings. I just included them because I already included information about my setup in the question, so this information might be helpful for anyone coming across this post later. In particular, we can see that according to ldmtool, both of my dynamic volumes use a chunk size of 128, despite being created with different block sizes in Windows. I guess this means that block size and chunk size are not synonymous terms. The commands ldmtool show disk and ldmtool show partition can be used to display further information.
Auto-mounting the Raid0 drives was a bit more challenging since editing /etc/init/mountall.conf never worked in my system and I wanted to be able to mount the spanned volume using a definition in /etc/fstab, and not use a script in /etc/rc.local.
Let me try, and give me a few days, as I am also confronting the hard drives issues, my bet is if i can't fix the Windows's booting, i may need to buy a new pair of SSD to replace, and then Windows's installation and then drivers installation.
5. Do i need to do a" F6 function key " method (for window 7 or up instead of vista) to put the driver ? If so, how to do the F6 method using a USB- flash drive? ...especially i would need to use ISO version to install the windows 7....
For question# 5- the video that was attached, the laptop was vista ultimate 32 bits (original OS), that's legacy based. But i am about to install another OS,-windows 7 professional ISO, which will be 64 bits based, This is the reason why I asked for the drivers at the begining, and F6 instruction. Please re-confirm.
I guess, now I would need to update the Intel Chipset driver from 32 bits or Windows 7 Pro genetic driver to Intel 64 bits driver, correct? I will go to another section of this website to look it up or confirm, thank you once again.
Hi msibanker: You are very welcome. Thank you very much for providing those results. Perfect, it is great to hear that the RAID configuration is now working properly, and yes, this time you will need to install the 64 bits driver version.

I have a HP Elitebook 8570w that was shipped with Windows 7. I have just installed Windows 10 on a seperate partition of my hard drive (so I have both operating systems currently). After the installation and running windows update everything seems to be fine except for a driver compatibility issue for `HP Disk Filter - SATA/RAID'.
I do not know exactly what SATA and RAID so I Googled them and as far as I can interpret the results I understand both concern my hard disk. My understanding is that SATA is an interface connecting my hard drive to my computer (whatever computer means in this context) and RAID is a technology for making the hard disk more reliable. I understand that this description is very basic and might oversimplify their meaning or I might even get them wrong.
Despite that I don't know exactly what this SATA/RAID technology does, I would stilllike to install the proper drivers to enable this technology for my hard drive as it seems it could either make the hard disk less likely to fail at some point or it might have other benefits I'm not aware of (maybe extending its lifetime).
I couldn't find drivers for this on the support.hp.com/drivers page and also the HP support assistant didn't seem to address the issue. It seems I need another (manual) way to install the appropriate drivers but I don't know where to find them or how to know which ones I need exactly.
I had the same problem in Windows 10. The only solution that worked for me, was to install the Windows 8.1 version on the HP page in compatability mode (setting = Windows 8). Since then the device manager does not show an exclamation mark anymore and reports, that the device functions properly. I did however not find a way to configure the device (start / stop / report on last use etc.). Does someone perhaps know?
Within this forum, if you search on the word "accelerometer", you will find TEN "accepted solutions" for problems related to "accelerometer". Please take a moment to read some of them.
The reason why the accelerometer error returned is because I accidently updated the application using HP Support Assistent which installed a newer version alongside the existing older one. Removing the newer version also prevented the error message from showing up upon boot up. So for me a working solution seems to be to uninstall HP 3D DriveGuard, install an older version of it (e.g. the Windows 8.1 one) and be sure to not update the application.
Unfortunately, today when I booted my computer, the error saying that the accelerometer application can't run on this version of Windows (Windows 10) has prompted again. I am fairly sure that I had rebooted my computer after the install, not receiving any error message but now it has come up nonetheless. I suppose that I could uninstall the driveguard and try and install the version before the Windows 8.1 one and see if it fixes the problem. I do not expect this though.
Assuming that installing HP 3D DriveGuard installs the correct drivers solving the SATA/RAID issue, as suggested on this thread, I have, as 8570w, installed an older version of the software which does not yield the error. I installed the Windows 8.1 version as well.
Have my first issue with my very first build after using computers and remembering the days before the interweb. I intended to be ambitious and to maybe over build with some headroom for future upgrades. Whatever I own I do try to ensure I get the best out of it and to that end I am bumping against installing Win10 after Raid 0 the two drives within the Bios. I have gone through the videos of trying to load bottom drivers then raid config but i still get get the windows setup to see them as raided drives. I need a detailed idiots guide rather than a detailed expert guide if that makes sense. Any help with videos or pdf's......at 43 I am feel it might be like teaching someone to use a spoon. Will continue my own searching and googling as there must be something I am missing.
3.Enter the Raidxpert2 menu in BIOS, you need to initialise (writes some data to the drives to prepare them for Raid) all hard drives that will be used for Raid. This option will be in the Raidxpert2 menu, so check all options.
I try raid 0. In bios I'm creating raid, and at first glance everything is fine (I can add screenshots from the BIOS). Then I made a bootable USB flash drive and added drivers there. During installation, I add 3 drivers sequentially from the DD folder, they are installed, but still two nvme disks are displayed.
