Why Windows Should Adopt ReFS as a Bootable Filesystem
ReFS could become a bootable filesystem — it only needs a few missing layers. No need to copy NTFS, just implement what the Windows boot process requires. Key missing pieces: System‑level journaling (not only metadata) Full hardlink + extended attribute support EFS, ACLs, USN Journal for security + Windows Update Boot‑critical atomicity for safe system file updates Bootloader‑compatible APIs (BCD, BitLocker pre‑boot, WinRE, Secure Boot) Goals: Use NTFS as a reference map, add the missing capabilities to ReFS, and optimize them using ReFS features (copy‑on‑write, integrity streams, block cloning). Result: A modern, resilient filesystem that can finally boot Windows - without losing its benefits.
Azure File Share - NTFS Permission Extremely Slow
Recently moved file server data to Azure File Share. No issue with mapping, opening files. The issue is when managing the permission. When updating/adding NTFS permission per folder, it is EXTREMELY slow. Any advise or workaround that you could share please. Thank you.
NTFS permissions - hide DLL from client, but allow execution
I have Server 2022 domain controller with AD. I am sharing a folder with clients, and this folder contains the exe and dll files for an application. I have set permissions so that the exe is visible to the client user which is fine. The issue is that the dll is also visible. I want to make the DLL invisible, but the DLL can still be used when the client runs the exe. Any advise would be appreciated. SijcookeIncorrect free space on NTFS (reserved clusters)
I have a very unusual issue on my Server 2012 R2. When formatting a partition as NTFS a large part of the space is reserved (~500Mb) For example, when formatting a 1Gb partition, I only have about half of it free. This happens even when creating a new NTFS partition on a new disk, that is, it is not a case of CHKDSK I created a 1Gb test partition and the command "FSUTIL FSINFO NTFSINFO X:" returns: total reserved clusters: 128,239 (500.9 mb) I can't understand why 500.9Mb are reserved. On another machine, doing the same, you have 14.5Mb reserved, that is, the 1Gb partition has almost 100% free space. I can't understand the reason for this behavior, I don't know if this is an error or if it is caused by some feature of Windows Server 2012 R2. Thanks a lot for any help.NTFS slow unbuffered writes during read of same file
I have an application that does high speed (>3000 MB/s) sequential unbuffered writes to large (256GB) pre-allocated files in NTFS. I also perform random unbuffered reads from this volume at a much lower rate when needed, using a block size of around 2MB. Reading and writing at high speed works perfectly almost 100% of the time. However, when I read from (a different part of) the same file that is currently being written, it causes the write speeds to suffer dramatically and queue depths to shrink below 1. The moment writing moves on to another file, the speeds pick back up to where they belong. This is confirmed on Server 2016 and 2019. This could be a difference in I/O scheduling, caching behavior, or something else that is dependent on the file system, but I can't seem to find any documentation on it. What could explain this behavior, and is there a workaround?
The main hard drive (the one C:\ is on) is showing as raw
OS: Windows 10 Enterprise The main hard drive (the one C:\ is on) is showing as raw. I got a bluescreen (wish I had recorded what it said on it before I restarted, but it's probably a moot point now) and tried to restart, but the laptop froze before Windows loaded. I did some diagnostic stuff using a recovery drive and it became apparent that something had happened to C (it was showing as a Raw drive named D). I reassigned the drive letters back to the correct ones but I can't find any way of indicating that the drive is not raw. The partitions are all there according to DISKPART (Recovery 300mb, System 100mb, Reserved 128mb, Primary 237gb, Recovery 663mb), and the System partition is still formatted, as when I list the volumes, I get a FAT32 with 100MB, but everything else is raw. Much of the drive is Bitlocker encrypted. I know there are 3rd party tools that claim to be able to recover things, but I am wary that it will render the drive inoperable, even if it will get my data back. I have most of my data backed up, I just want a functioning OS that has all of my applications.
