WindowsPE uses the same method that Windows OS itself does as far as I'm aware. See here for an explanation from MS: https://support.microsoft.com/en-us/help/937251/disk-drive-numbers-may-not-correspond-to-the-sata-channel-numbers-when

What is the actual memory usage with the hardware mapped memory removed from the total?

This is incorrect. If the motherboard fails, you can migrate the array to any other board (same model or different) as long as it has the same storage controller on the board. On the destination board, you would enable the RAID with no disks attached, shut it down. Then connect the disks from the other board to the same ports as the original board, boot the system and enter the RAID manager. Presuming that the disks themselves are sound, at the worst you'd have to do a rebuild. So it may not be a simple solution, but besides being able to read a single disk as jaclaz mentions, it is not a total loss to lose the board. But then again, this brings up the other point, RAID is not a backup solution. You lose the array, its a pain but you would have the backup, right? I will note that I have only done array migrations with a RAID1. I have never found RAID0 to be worth the risk for OS volumes and hasn't been a viable speed option since the advent of SSDs.

Then perhaps it is backwards, and that some RAID software will refer to a single disk outside of an array, while still being managed on the controller, as a JBOD disk, even if singular. Terminology aside, there are still some RAID software on desktop boards that do not allow for a single disk to exist outside of an array and documentation for those boards rarely mention such a thing. Usually only find out if it is possible by attempting it, unfortunately.

Well perhaps, but it is, in effect, what a disk on a RAID controller is when out of the array. With a desktop board, you do not get the luxury of having SATA ports not be on the controller when you change the setting in the BIOS. On modern systems, only M2 sockets get this luxury.

Using generalities, a non-specific desktop motherboard with RAID capability will typically have only one storage controller option for all of the disk connections. As opposed to a workstation or server class board which can have two controllers, assigned to specific or selectable ports. In the general use case of a RAID capable desktop board, it would infer that changing the SATA mode to RAID will change all of the ports to that controller. So the SSD in the first post would need to be added as a JBOD, while a RAID0 or RAID1 is used for the two 3 TB disks.

I'm presuming based on your other topic that you have figured this out already, but here is a relevant reply. When installing Windows on a system with multiple disks/arrays, I would recommend that you only have the OS disk/volume present at the time of installation. The reason for this is twofold: 1. Windows Setup will sometimes write boot data to another disk/volume than the one the OS is installed onto. The issue with this is that if the other volume is removed or has a problem, the OS won't boot. 2. Windows PE will assign disk numbers based on first-come first-served enumeration. Because all hardware is different, even between different systems with identical hardware, the system may make available disks in an uneven order. As such, there are situations where a card reader or RAID volume on a controller gets enumerated before the SATA ports, and this can cause an issue in some installation scenarios because Disk 0 ends up being something other than what you would think. I have never seen an ODD get Disk 0 designation, and have yet to see a NAND/NVMe in M2 slot be anything other than Disk 0... Because you cannot control enumeration of disks to Windows, the best practice is to remove the possibility of the incorrect device being detected as Disk 0. When using motherboard RAID in the scenario outlined above, the controller needs to be capable of creating a array with 2 or more member disks and 1 disk set to JBOD. Unfortunately, specs for RAID on motherboards rarely have a matrix of possible combinations documented, and there are definately instances of desktop motherboards being incapable of this configuration. The only way to know if it is capable is to attempt to do it, or find someone who has tried or has the board. For an Intel chipset board with Rapid Storage controller, you set the SATA mode to RAID. Then you would reboot and enter the RAID software and create 1 array using the two disks, and set the other disk as a JBOD member disk that is separate. If it allows this configuration, then you can either disable the array, or disconnect the disks physically, to install the OS. After the OS is installed, re-connect/enable the array disks and boot into the RAID setup to verify the array is healthy. Then boot into Windows, go into Disk Management and you'll be able to format the virtual disk that is detected.

If you have access to hardware (v)RAID, there is no reason to use the software equivalent. You do not mention the RAID level, presuming RAID1 it is possible to boot a degraded disk in another machine, provided that machine has the same RAID controller and you connect it to the same SATA port. However, this is not a scenario that is considered in a pro/con argument regarding RAID. It is because such an action is only considered if there is a motherboard failure. Even so, I would not recommend using original degraded disks on another computer, instead use a copy of said disk. Hot swap in RAID is not for making member disks portable, but to allow for powered replacements. If it is a RAID0, you cannot use a degraded member-disk in any other system. When RAID is enabled in the BIOS, you use the board software to create your array. The board software then presents this as a virtual disk volume, which Windows sees as only 1 device.

You can do it using DISM /set-ScratchSpace, but be aware that your ramdisk size is dependent on the amount of system memory available (and addressable if using 32bit). Example: Dism /image:C:\test\offline /set-ScratchSpace:128

WELL! I just got an email now for a PM. But I had gotten PMs over the past week that I didn't know I had until I got here. So it works sometimes.

Bump. Not receiving email notification for PMs.

If you are having this error, you'll need to run MGADiag.exe and click copy, then paste the report into this thread. Then we can tell you what the problem is. http://go.microsoft.com/fwlink/?LinkId=203456

Yes, we do pride ourselves in at least trying to figure out actual solutions, rather than the typical "just reinstall Windows" or "update your antivirus" type posts you see a lot of other places.

RAID is not a backup solution, never equate the two.

I have accumulated all sorts of weird adapters over the years as well. I rarely try to figure them out, just put them in a bin of mystery connectors.

Interesting video showing the "proper" procedure of doing a hard disk reshell. Apparently a bit old, however may be worthwhile to watch for anyone interested. Note that this is a situation where they change out the shell of a hard drive because the spindle bearing is bad. They are not doing any other things like swapping PCBs. It is not clearly seen but the original PCB from the first drive is what is mounted on the new shell. So this is not a case of just moving the platters from one drive to another. They show some tools at the end also, but none of that is really explained.

A picture would be nice, even if you can find a stock photo of what you have. From your existing post "kind of port that a flash drive could go into" makes me think that one end is a USB Type A receptacle. However, the other side, the RJ45, you don't specify if it is a port or a connector. I'm sure there are various uses for such a device. A quick looksee on Amazon (ASIN: B005DDI51U) for example, says this particular adapter is to connect a USB ADSL modem to a router. If the thing you have is not the same as the thing from Amazon, then I used this phrase in google search: RJ-45 USB Type A adapter

If to win means we can't see anymore BSOD from around the world in this thread, then no. :p

You can use onboard RAID if you want but the controller would need to support JBOD+RAID. Because you say you want to use RAID1 for data and your other disk wouldn't. So in a RAID scenario, you'd have your OS on JBOD and the other two on the array. Not all controllers on retail boards can do this. And, to make matters worse, this information is not usually in the manual. You'd have to test it to see if you could add a single JBOD disk in addition to the RAID1, and still be able to boot on the JBOD. If you can't run in this scenario, then you should use a controller card for the array and leave your board on AHCI. If you are going to install Windows using Windows Setup (DVD install), I recommend that the RAID card or the disks are not connected until after the OS is installed. If you are going to go with a RAID setup, it is recommended that you purchase your replacement disks at the same time as the main ones. When a disk fails, you order a replacement for the replacement. The idea then is you have your spare disks (whatever the fail maximum is) ready and waiting. For a RAID1 I would say 2 disks. So to properly prepare for a RAID1 in your scenario would be to buy 4x 10TB disks, 2 for your array and the 2 replacements you keep on hand. You should not use the system when the RAID is in degraded or rebuilding. Using the system in this state, especially when you have lost half of your failsafe (1 disk in a RAID1, 2 in a 5, etc) is risky, and even if not in rebuild, data transfer in either direction, or the entire OS itself may become very slow. If you have the replacement disk available immediately at the time of failure, you will be able to maximize your uptime rather than having to wait for a replacement to come in the mail. I have never liked Windows mirror, but that is probably because of my experience with desktop and enterprise RAID controllers.

Where do you get this 3.4% number from? This from 3 years ago? https://mspoweruser.com/windows-is-the-most-popular-operating-system-in-the-us-according-to-the-federal-government/ Which cites its data source as the US government, which then goes about to say this: "On November 8, 2016, the Office of Management and Budget (OMB) released a memorandum on Policies for Federal Agency Public Websites and Digital Services, which requires federal agencies to implement the DAP javascript code on all public facing federal websites." That is how they get that figure. To be clear, the actual headline is not "Of Windows OSes that people use, 3.4% use XP" instead it would be "Of Windows OSes that visit US government websites and have javascript enabled, 3.4% of visitors use Windows XP, with a +/- percentage difference to those using XP (and not using XP) with modified user agents." There are two things that are immediately clear: 1. We can never know a nice number, such as the "50 of 45 million" in your question. Companies need their analytics, and the best way to determine OS usage (outside of malware) is to read browser User Agents. However, this method is severely limited and can never give an accurate number. 2. The common analytic method requires specific circumstances in order to be counted. It not only requires javascript and un-altered (or recognizable) user agents, but also requires that a person actively uses a web browser to go to a specific website. So it cannot count Windows XP computers that do not go to government websites, XP computers that do not go to any websites, and XP computers that are isolated or not connected to an external network/internet. So does that mean there are more than 3.4% of Windows XP computers out there? Yes and no. All of the reasons posted why a Windows XP computer would not get counted, while still existing and operational, are the same reasons why a computer with any other OS isn't counted. And then there are the ones that do get counted, but as other OSes due to how the information is gathered. It could be more, it could be less.

I try to use as little amount of apps as possible. Even I had the opportunity to scan a QR Code yesterday, but didn't know how to do it. Then someone told me I needed to download an app. I looked into the PlayStore and I didn't really want to download any apps... so I didn't scan the QR Code. Microsoft has an RDP app that works well: https://play.google.com/store/apps/details?id=com.microsoft.rdc.android I mean, as well as you can expect RDP to work on a phone. I use it to test RDP connections in the office as RDP to the public address is blocked from internal connections (including the wlan) but not through the cell phone network.

Let's go back a second. At which phase of installation do you get the 0x7B stop error? Windows XP install phase has two main parts: 1. booting off the install media, install and restart 2. booting off the destination drive to finish installation If it is in phase 1, then you need to identify the path to the install media. If it is phase 2, then you identify the path to the hard disk. AMD only provides Win7+ and Linux drivers for the B350 SATA controller. I would recommend that you put the XP on a disk by itself and connect it to one of the two ports used by the ASMedia controller. You may have better luck in finding an XP driver for that device considering it is older. Otherwise you should research any instances where people have tried to put XP onto a Ryzen board to perhaps get some better search results.
