Hard Disk – How to Assign a UNC ID to a WiFi Router Hard Disk – under Windows 10?

I have a router (TP-Link Archer C8, at 192.168.nn.1) with a 2GB hard drive in a USB 3.0 port. According to TP-Link, the "Network / Multimedia Server Name:" is TP-LINK_99999X (example of IP address and device name).

Hard disk access works correctly via \ 192.168.nn.1 volume1 Directory in Windows Explorer, but in light of this thread https://answers.microsoft.com/en-us / msoffice / forum / all / adding-mapped-network-drive-to-the-office-2010 / ef12d2c6-4b55-42fe-b28c-527d8da6d6fb I need to refer to the drive via a UNC address.

The first attempt was simply to enter \ TP-LINK_99999X volume1 Directory in WinExplorer, but alas – it did not work.

So what?

sql server – What could be the cause of my high disk I / O latency (sys.dm_io_virtual_file_stats DMV)?

These are the results of the DMV sys.dm_io_virtual_file_stats query. (I'm adding calculated fields for clarity).

DM IO Virtual File Stats

I find that some basic operations in database 7 are throttling bottlenecks that I run in database 6.

For example, I have a table in database 7 that is not used anywhere and contains a lot of lines (about 300 million). In Database 6, a mass insertion of hundreds of thousands of records occurs every hour throughout the day.
If I run a simple SELECT COUNT(1) FROM Database7.dbo.UnusedTableInDatabase it takes about 10 minutes to come back, and it seems to consume a lot of server resources, IO in particular. My mass insertion work being run continuously on the database 6 almost stops and a delay begins to develop.

One thing I know is that Database 7 has its data and log files on the same logical drive.
Database 6 is properly configured so that its data and log files are on separate disks.

Where should I start digging next to try to solve these problems?

macos – How can I delete some disk images in my recovery partition?

When I upgraded my MacBook Air mid-2011 from Sierra to High Sierra last year, I was having some installation issues … which resulted in the creation of at least 2 or 3 disk images in my recovery drive.

I have disk image files that they do not belong to (like a keychain) and my system has been compensated by placing them elsewhere.

The repercussions are more important than what I can list here … The two most troublesome are:

/dev/disk4 in /Volumes and /dev/disk12 on /Volumes/untitled.

-bash-3.2# mount

/dev/disk1s1 on / (hfs, local, read-only)  
devfs on /dev (devfs, local, nobrowse)  
/dev/disk3 on /private/var/log (hfs, local, union, nobrowse)
/dev/disk4 on /Volumes (hfs, local, union, nobrowse)
/dev/disk5 on /private/var/tmp (hfs, local, union, nobrowse)
/dev/disk6 on /private/var/run (hfs, local, union, nobrowse) 
/dev/disk7 on /private/tmp (hfs, local, union, nobrowse)
/dev/disk8 on /System/Installation (hfs, local, union, nobrowse)
/dev/disk9 on /private/var/db (hfs, local, union, nobrowse)
/dev/disk10 on /private/var/folders (hfs, local, union, nobrowse)
/dev/disk11 on /private/var/root/Library (hfs, local, union, nobrowse)
/dev/disk13 on /private/var/root/Library/Containers (hfs, local, union, nobrowse)
/dev/disk14 on /Library/Preferences (hfs, local, union, nobrowse)
/dev/disk15 on /Library/Preferences/SystemConfiguration (hfs, local, union, nobrowse)
/dev/disk16 on /Library/Keychains (hfs, local, union, nobrowse)
/dev/disk17 on /private/var/tmp/RecoveryTemp (hfs, local, union, nobrowse)
/dev/disk18 on /private/var/tmp/InstallerCookies (hfs, local, union, nobrowse)
/dev/disk2 on /Volumes/Macintosh HD (hfs, local, journaled)
/dev/disk12 on /Volumes/untitled (hfs, local, nodev, nosuid, no owners)

windows – The size of the disk of the host (Win10) was badly noted after creating the fixed menu in VirtualBox on a guest (Ubuntu)

My problem is reproducible in a rather specific configuration, let's first give a context:

Host OS: Windows 10
Virtual Box 6.0.14 (latest)
Guest OS: Ubuntu 19.10 x86_64 (kernel: 5.3.0-24-generic)
Gitlab-runner: 12.5.0
Docker: 19.03.2 (latest)
CMake: 3.16 (latest)
ninja-build: latest
Dynamic VDI: 150Gig (max-use is ~ 70 Gig)

A gitlab runner runs shell commands in a Linux guest OS in a virtual box located above the host operating system (Windows 10). The host disk has a total capacity of 250 gigabytes, while the Linux dynamic partition is set to 150 gigabits maximum, leaving about 60 gigabits free. Gitlab-runner synchronizes the project source from an external submodule git, builds a dependencies menu) and pushes it to a repository. It then creates a second fixed menu that performs a number of CMake / ninja install operations over the source. If the fixed menu contains too many commands (for example, more than 10 RUN layers), the host operating system suddenly goes from 60 GB of free space to a few kilobytes, thus inviting the system to Host host (Windows 10) to display a blue warning box indicating that disk space is sufficient. is extremely low. Virtual Box then suspends the guest OS (Ubuntu) and all stops.

If I keep an eye on the disk space in the host operating system during this process, the available space remains the same until it starts to disappear. After that, the Windows Explorer and the Disk Management Tool report that the drive is almost full (in KB), while WinDirStat can not find the missing gigabytes.

Strangely, I can fix it by rebooting the host operating system (the entire PC), after which the free size is reported correctly again, then I can restart the virtual machine and restart the build.

Q1: What is causing this sudden disappearing of free disk space?
Q2: Is there a way to fix it without having to reboot (and exit the VM)?
Q3: Has anyone else experienced similar strangeness regarding the disk free size being misreported in certain cases?


This question was asked in the first place (and closed off topic) on SO, but may be more relevant on this forum.

I have also tried TreeSize Free instead of WinDirStat, but it has also not been able to indicate files occupying space "lost". Whenever I run a fixed menu process in the virtual machine, the problem starts to recur.

Wallet.dat of the mobile hard disk is not saved after sending Bitcoin

there are no coins in it.

Bitcoin wallets do not really contain coins. The only important piece of information in a Bitcoin wallet is the private key (or more if you have imported several rather than scanning them). Bitcoin wallets look more like your keychain and not the leather wallet in your back pocket.

Know the amount of money you control in the public shared / replicated blockchain.

A wallet will usually show you a "balance" which is the amount calculated by examining the blockchain. A wallet "complete node" may not display the correct value for the scale if it has not yet "synchronized" its copy of the blockchain. An SPV wallet may display an incorrect amount if it can not contact a complete Bitcoin node.

Wallet.dat of the mobile hard disk is not saved after sending Bitcoin

Although frequent backups are a good idea, you should be able to recover control of all your money simply by using the private key (or key phrase of some portfolios) to recreate your portfolio. You should practice this kind of recovery. Neither the private key nor the starting phrase changes when you switch from Bitcoin.

Low disk storage space, 47G is used by Bixby Vision

I started having little disk space a week ago. Everyday, I clean the cache and data of applications, even by uninstalling applications, but the problem of space persists after a few hours.

I have downloaded the application DiskUsage and I found that "Vision Provider" uses 47G (photo attached). I have never used Bixby, so I do not know why he takes all this space.

How can I delete the Vision provider to free up disk space?

macos – How to create a disk image from an APFS volume?

I have a 1 TB APFS encrypted SSD that I extracted from my MacBook Pro, now dead. I've placed the drive in a USB docking station and I can mount it properly after entering the disk password. However, I can not take an image of this drive from Disk Utility.

When I select the volume, the new image -> of "macOS" in the menu bar is grayed out. As I understand it, this is normal for APFS volumes; you can only create images of APFS containers or physical disks. When I select the container or disk, I can select New image -> From [container or disk], but when I assign it a file name and I click Save, all it does is to me say "Operation canceled".

I first tried to dismount the volume, but I got the same results. I've also tried pressing New Image -> From Folder and Selected / Volumes / macOS. Then he gave me the error "Operation not allowed."

Thinking it was a problem with Catalina, I started in Mojave and tried the same thing. This time, the Disk Utility has created the image as expected, but when I try to open it, the error message "Can not open the image of the disc. Reason: No mountable file system.

How can I take a picture of this player? Keeping in mind, I do not wish to use third party software. This is something that can be natively handled for non-APFS disks, and I do not see why that would not work for APFS containers.

Oh, and one more thing:
First aid does not report any errors with the volume. I can read and write files very well. I just want an archive snapshot to reuse this SSD. Thank you.

hard disk – Why dd give me an error at the end of the scratch of the disk?

I'm running Cygwin on Windows 7.

I used the following dd command to safely erase a 1 TB mechanical disk:

dd if=/dev/zero of=/dev/sde bs=4M status=progress

About 2 and a half hours after cleaning started, about the time I expected it to be over, and after I managed to write about 930 GB (or more, presumably) on the disk, I had the error:

dd: write error & dev / sde: error input / output

I restarted the command with seek to try to reproduce the error by writing the last gigabytes of the file to zero:

dd if=/dev/zero of=/dev/sde bs=4M status=progress seek=231100

… and of course I had the same mistake:

dd: error writing '/dev/sde': Input/output error
7368+0 records in
7367+0 records out
35196174335 bytes (35 GB, 33 GiB) copied, 405.703 s, 86.8 MB/s

It appears that the cleanup was successfully completed, but if so, why was the error generated?

What could be the cause and how can I avoid it?

Disk storage | Talk Web Hosting

Hello everyone,

what do you use to store unused hard drives these days?

The storage situation of my drive becomes uncontrollable.
I'm looking to use an old rack-mountable storage array, like the one you need to extract the server from the rack to access the drives,
I saw them but I do not remember any model names.

All suggestions have appreciated.

regions – Surface of the calculating section between the cylinder and the disk

I create a cylinder whose central disk is placed at the position vector v1 and whose orientation is given by the normal vector of the disc n1. The second object is a disc, integrated in the same box, but as I do not know how to draw discs $ 3D $ in Mathematica, I use a very fine cylinder to approach the disk, which is placed at v2 and orientation n2. Both have a diameter d=4. Here is the configuration:

v1 = {0.5, 0.5, 0.5};
n1 = {1, 1, 1};
v2 = {1, 1.5, 0};
n2 = {1, 1, 0};
d = 4;

ef1 = 5; (*elongation factor of cylinder 1 to find endpoints to draw*)

ef2 = 0.00001; (*elongation factor of cylinder 2, to approximate disk*)

cyl1 = Cylinder({v1 - ef1*n1, v1 + ef1*v1}, d/2);
cyl2 = Cylinder({v2 - ef2*n2, v2 + ef2*v2}, d/2);

And gathered: Graphics3D({Opacity(.5), cyl1, cyl2}):

As seen in the picture, the cylinder goes through part of the disc and I try to find out if:

  • Is there a way to calculate the disk area that intersects the crossover cylinder? A naive approach using Area@RegionIntersection(cyl1, cyl2) seems not to work (returns Undefined).
