Acronis Disk Image cannot clone to the same storage SSD

I wanted to clone my computer.
My computer is using 450gb SSD.

I used Acronis disk image to clone the SDD to another new SSD (with same storage 450gb) but the new SSD cannot show in Acronis disk image software. (New SSD has already formatted)

I tried to use bigger storage HDD that is 1tb. This time, it successfully clone.
Why it cannot clone to the same storage SSD?

nfs – Google Cloud Filestore, How to limit the disk usage of each user directory?

I’m currently using Google Cloud Filestore to store user data. Each user has a separate directory, in which they can store any data they want.

However, as the users grow, the capacity cannot handle all the uploaded files. Therefore, I want to set the usage limit of each directory (for example, /my_filestore/alex can only store up to 10GB).

At first, I plan to use quota utility tool, but this tool cannot work with NFS mounting, as NFS.mount does not allow usrquota option.

Is there any other alternative to do implement this restriction? Thanks so much.

disk management – Which one is the most accurate in calculating the Shortest Service Time First (SSTF)?

Request order for tracks: 44, 35, 50, 12, 88, 100, 93, 70, 120

  1. Refer to disk track figure on the upper right corner.
  2. Arrange the request on the disk track from A to I.
  3. With current read location at track 90. Fill in the access graph above according to the SSTF.

Should I do the order like this: a] 90, 88, 93, 100, 120, 70, 50, 44, 35, 12

Or: b] 90, 93, 100, 88, 70, 120, 12, 50, 35, 44

  1. Read location at track 90. Fill in the access graph above according to the SCAN.

Is the correct way of ordering it like this way: a] 90, 88, 70, 50, 44, 35, 12, 93, 100, 120

or: b] 100, 88, 12, 50, 35, 44, 93, 70, 120

I have seen many tutorials but I got a bit confused


The date modified of a deleted file in a disk image is having a later date than the last system Log On date

I am analyzing a disk image for a forensic investigation and I see deleted files having a later date for last modified date than the last system log on date.
Does this means someone has created a raw image file and delete those files from the forensic image and then burn it to the disk again.
Can some one do this using a linux live CD.

windows – Is there a reliable way, via powershell, to detect if a user has been logged on with a temporary User Profile Disk?

I am migrating my users from a Server 2012 R2 farm using Roaming Profiles to a Server 2019 RDS deployment using User Profile Disks. I have created a script that will copy the “important” folders from the UNC where the roaming profile is stored into the user’s new UPD, and have deployed that script via GPO as an immediate schedule task that only is created if a particular “Profile migrated” flag is non-existent (which the script obviously creates).

It is works very well under “normal” circumstances.

But, if a user happens to log on and their UPD is locked (an admin user primarily, who has the rights to log into multiple session host servers at once, and knows that this might happen under those conditions) and they get assigned a temporary profile/UPD, I want to detect that and NOT run the script.

I have not found a reliable way that I can check to see if the current session is using a temporary profile that I can use in “Item Level Targeting” to further filter and prevent this scheduled task from being created if the user is running under said condition.

Any suggestions? Registry settings seem to be the most likely candidate, but I haven’t found one that works yet.

Monitor disk activity by process and by file in linux like windows ressource monitor

There are so many tools to monitor disk activity in linux like htop, dstat or iotop. However I didn’t find any way to monitor disk activity by process and by file. In windows ressource monitor does this job perfect.

I’m looking for a console tool to do the same in linux.

How to Restore a virtualbox ubuntu 20.04 backup on Main Hard Disk

I’ve searched a lot, but I didn’t find the solution to this type of question!
I have an installed windows 10 on my Laptop and an installed ubuntu 20.04.01 on my Virtualbox. I want to know is it possible that I get a full backup from my ubuntu inside the Virtualbox and then delete my windows and after installing ubuntu 20.04 as my main OS, restore that back up over it and use ubuntu forever after that?

I would like to know if it is possible; how can I do that? And if it isn’t, what is the reason?

I really appreciate any help you can provide.

windows 7 – Getting Rid of Software Records for Software installed on an external disk?

So I’m cleaning out an old computer, and several of the programs it thinks it has were actually installed on an old drive, that’s now gone. For some of them, it prompts to get rid of them because it can’t find the drive, so that’s all well and good.

But, for LibreOffice and a couple of others, it tries to run the LibreOffice Uninstaller, and only quits with a fatal error when the LibreOffice uninstaller can’t find the drive.

The difference here is that in the first case, Windows can’t even find the drive with the uninstallers on them, so it prompts to remove them; but in the second, its found the uninstallers on the local disk somewhere and is trying to run them, prompting a fatal error when the uninstaller can’t find them.

What should I do here? How can I remove what’s left of these programs/erase their names from the family tree?



big sur – How to setup Disk Quotas on macOS Big Sur?

You would need to install quota-tools from Homebrew and then use that to configure your disk quotas.

Install Homebrew (if you haven’t done so already)

/bin/bash -c "$(curl -fsSL"

Then install quota-tools.

brew install quota-tools

Afterwards edit your /etc/fstab to enable disk quotas for the file sytem

/dev/rdisk0 /home apfs defaults,usrquota 0 2

Then run edquota to add disk quotas for the individual users:

sudo edquota -p user1 user2

After that restart the system to have the disk remounted and disk quota to take effect.
