el capitan – trying to erase external SSDs visible only in terminal mode

I have an SSD drive that has been removed from a MacAir and placed in an eclipse. I must have screwed up the directory by deleting files from the drive and not disassembling it because the drive is invisible in DiskUtil. I can see it in Terminal, but when I try to erase the drive with the help of diskutil, it starts up and reaches 30%, and then stops with the message. error below. The player has been saved, so I want to start all over again. The reader was in JHFS + format. Help?

partition – Disk Utility does not erase the external drive

The other night I was working with my 6 month old MacBook Pro and a 6 month external drive connected. I moved to my seat and the external drive slipped and abruptly disconnected from the port. When I reconnected, he asked to initialize, ignore or eject. After some research, I determined that the directory had been messed up by the disconnection. I could either pay to recover the data, or initialize and reapply all the data. I chose to boot.

During the process, the external drive appears only in the Disk Utility. I have tried to remove the disk utility and the terminal, but the error persists: "I can not write the last block of the device". In Disk Utility, the partition option is grayed out and even though the view shows all devices, Passport does not display a partition. When I try to click the eject button in Disk Utility, nothing ever happens.

How can I erase this external drive for reuse?

Copying files from my local drive to Google Drive through Windows Explorer uses the local disk space to make the copy. How can I erase this temporary data?

I'm using a Windows 10 PC. One way to copy files to Google Drive is to use Windows Explorer. I can copy or drag files from my local hard drive to Google Drive accessible through Windows Explorer. Copying files to Drive in this way is fast, certainly much faster than downloading them directly to Drive via Chrome. When I copy a file through Windows Explorer, the process controls this storage space on my local drive, but when the copy is complete, that storage space is not automatically released. From what I understand, this copy of local storage is supposed to erase automatically, but I have not seen it and I do not know in which conditions or what events it is supposed to wipe off. So, if I copy more than 20 gigs on Drive, my C: disc will have 20 fewer gigs, even after the copy is done. Of course, I have the original 20GB files on my drive, and now 20GB on Google Drive, but how can I erase those 20GB of copy data on my local drive? I tried to defrag, but it did not do anything. Thank you.

Android versions – My 6edge is 32gb. I've used about 13 GB, but in the storage option, it shows that 31 GB is used … where is my memory rest. Please erase

applications – Can not erase application data


  • Samsung Galaxy S8
  • Android 8.0 Oreo
  • Application based on this Google example that works correctly on other Galaxy S8 phones


By trying to start from scratch on my application installed by the APK file, I am unable to delete the data from the application.

  • Hit the "Clear data" button in the application settings
  • Operation adb shell pm clear com.myappsname
  • And uninstall / reinstall

Still leaves 16.38KB in the Application Storage Data category.

All I can understand is that this is what is causing the application to malfunction on this particular phone, since it is correctly installed on other S8s. Looking at logcat, I can not really diagnose anything that is wrong with the way apps work, other than the fact that it's not up to date to update the location.

How to completely erase the data from the application (it remains 16.38 kb)?

Thanks in advance!

Hard Disk – Is it faster to resize a Time Machine partition or completely erase it and save it again?

I have a Time Machine partition of about 500 GB that I would like to reduce slightly. My internal source partition is about 400 GB.

Resizing the partition would be extremely slow because Disk Utility needs to check all the hardware links that Time Machine uses behind the scenes. On the other hand, it would be extremely slow to wipe and save again.

Will one or the other generally be faster? Is there a tipping point for disk size where it becomes more economical to change the strategy?

(I'm using an SSD drive internally and a hard drive in rotation, connected via USB 3. The source and destination are encrypted.In addition, I have a second backup drive.Therefore, if I cleans and backs up, be temporarily unprotected.)

Apps – How to completely erase my device from the apps of a particular company?

The identification of the Android package is not easy.

I can call a new app all I want, there is no designated location to write the name of the company for research purposes.

Ok for example
I could call my app region.company.appname because the guidelines encourage developers to use this format to name the application packages … com.entreprise.tester For this example, COM is the region (Commonwealth), Company is the name of the company and tester is the name of the application.

To identify the applications created using the same naming rules and company name, you must look up the package name for all applications and look for the corresponding company name.

This will not show you everything because the developer can easily call the application anon.unknown now the region has been removed, the company is Anon and the name of the application is unknown …

This makes it extremely difficult to recognize all packages by a specific developer.

At the time, the Google Play Store only required that the application be signed by a developer key (used for all applications). However, developers must now create a new key for each application that does not share the credentials.

You may have already checked the key hash for all applications and those using the same key come from the same company (developer) … but that has changed.

In my experience, there is no regulation to leave an impression of your company … If you wish, you can give your company the name of your company identical to that of your application … For example, Facebook is created by Facebook, the company. may have been created specifically for the application, so the company bears the same name, ie each application will be created by the development team for that application.

So, apart from the fact that the developer uses the same naming rules for each application … It is not possible to find all the applications created by a specific company …

The company may have side projects that use their respective names as the creator's identity.

The only possible way is that if the IDE (Integrated Development Environment) places a kind of fingerprint on the software using information from the computer hardware … this can always be avoided by using a different computer on which the development continues.

So, as far as I know, it's not quite possible.

The best alternative is to read the package names and search the corresponding companies (shared user IDs and package names).

If the application is installed on your system, you can not uninstall it without root access. You must disable it.

System> Applications (plus> Applications)> (Selected Application)> Disable.

I hope that the developer did not use different naming rules for each application, and so on. Good luck to find them all.

I've used hdparm secure erase on a SATA USB drive. Is it beyond recovery now?

By acting on information in an outdated version of ULSAH, I tried to erase my old backup disk (a SATA disk connected by USB, not an SSD) using hdparm with the following options (rather the how a toddler will take it):

hdparm --security-set-pass foo / dev / sdb
hdparm --security-erase-enhanced foo / dev / sdb
hdparm --security-erase foo / dev / sdb

(I've used the third command for good measure.) Later, the disc behaved unpredictably.

hdparm --security-unlock foo / dev / sdb

seemed to allow to write a new partition table and start a format, but this partition table did not remain. I started having input-output errors when trying to do something with the disk. Repeated attempts to unlock the disk, or whatever, using hdparm had no other apparent effect.

As I just reported (see http://www.tomshardware.co.uk/answers/id-1984547/secure-erase-external-usb-hard-drive.html) idea seems to have been misguided. in the first place. And having gone on this task without first googling, I do not deserve, and do not hope, sympathy.

But is it possible to say if I've definitely blocked the external drive? Is there a type of diagnostic tool? It would be a shame to throw away equipment that could still work. (As a backup record, life was beautiful, with a lot of free time.)
