Disk Utility – Question about custom partitions, VeraCrypt and APFS

After a few years of deafness, I switched to High Sierra.

Now I have an external hard drive for backup with the following layout:

/ dev / disk6 (external, physical):

0: GUID_partition_scheme * 2.0 TB disk6
1: EFI EFI 209.7 MB disk6s1
2: Apple_APFS container disk8 80.4 GB disk6s2
3: 00000000-0000-0000-0000-000000000001 1.9 TB disk6s3

Partition 2 was an HFS + file system that I converted (by reformatting) to APFS and that contains a clone of my macOS partition.

Partition 3 is used as a VeraCrypt container and formatted as HFS +. So far, I could not reformat it in APFS because Disk Utility complains that the process requires "an entire disk". The command line also failed.

At this point, I think I understood that the operation is not possible. Not a big deal as this would only bring a slight improvement to a backup disk (with rsync) and APFS. I just want to know if I got it right or not.

Many Thanks.

Veracrypt boot loader does not appear after running bootrec commands during Windows 8.1 reset

The symptoms and processes described below:

I have full disk encryption on all drives, including the system drive.

I have not decrypted any drives before attempting to reset my Windows 8.1 operating system with the original CD (full reinstall, no data save). I realize that's probably why I'm in the situation I'm in. The answers in this thread led to this decision.

The first hurdle was when I started up with the Windows installation CD and tried a reset. The error message was:

"PC can not be reset. A required drive partition is missing."

I googled and tried to solve the problem by repairing the Master Boot Record (MBR) using the following commands. The answer / feedback is listed under each command:

bootrec / fixmbr

The operation was completed successfully

bootrec / fixboot

The operation was completed successfully

attrib C: Boot BCD -h -r -s

No path found – C: Boot

bootrec / rebuildbcd

Scan all hard drives for Windows installations
Total identified Windows installations: 0
The operation was completed successfully

So it seems like the disks are encrypted so I can not recover the master boot record. It does not recognize my file system or installation (see & # 39; for more information & # 39; below).

So I go to start my computer and decrypt the hard drive. I can not access the veracrypt boot loader. When I turn on my PC, the blinking underline cursor will appear, go down a line and stay flashing no matter how long I leave my PC or what buttons I press. I am not prompted for a password. Veracrypt Bootloader is not displayed on the screen.

At this point, I can not access the veracrypt boot loader nor see how to completely reinstall windows using the installation diskette.

It seems that I have excluded myself from my PC without being able to restore it or reinstall it.

Additional Information:

I've created a veracrypt recovery USB drive from the Veracrypt Rescue Disk.iso that I had on a USB drive. I created it with unetbootin on a Mac. When I try to boot my PC with this disk, I see the same veracrypt boot loader problem: the underscore cursor flashes one line down and then nothing else happens, no matter how long I leave it.

I can see all my volumes and disks with DISKPART on the command line. I can see the two partitions on my system SSD (350 MB system partition + rest of the disk) and my non-system disk with 1 partition. They are listed as Fs: RAW. I think that's because of the fact that they are encrypted.

I tried to use

chkdsk / f

on my system drive, it is read-only. I was able to disable the read-only on my storage drive by using

DISKPART> Attributes disk clear readonly

however, could not disable this attribute on my system drive.

I do not want to keep any data on the hard drive, I just want to perform a full reinstallation with the original Windows 8.1 hard drive. I want to wipe it completely, do not need to keep partitions, etc. Install completely clean. Suggestions are welcome, thank you.

veracrypt – How do I force my system to see my hard drive as a 4096-byte?

I want to create a VeraCrypt volume on my external 4TB hard drive with 50GB of external volume and keep the rest hidden. However, during the setup process, the following error message appears: Error Image

I do not want to divide it into two partitions, so I checked it sudo fdisk -l / dev / sdc to find out how big the sector is:

Plate / dev / sdc: 3.7 TiB, 4000787029504 bytes, 7814037167 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical / physical): 512 bytes / 4096 bytes
I / O Size (Minimum / Optimal): 4096 bytes / 33553920 bytes
Disklabel type: gpt
Plate Identification: 57DF69GQ-C896-R557-EE98-54GF68GF7898

End type of the device start types
/ dev / sdc1 2048 7814035455 7814033408 3.7T Linux file system

How do I force my system to see the hard drive as 4096?

truecrypt – Veracrypt system encryption on SSD. Do I have to crop the hard drive right after quitting? As?

I want to encrypt my operating system, which resides on SSD (Windows 7, X64, Mbr partition style).
From what I know, veracrypt will encrypt the entire hard drive, not just the actual data.
not only! The empty space (inside the decrypted disk) is "filled" with random data to allow hidden OS / containers.
This means that the SSD thinks that the SSD is full and wear is limited, which reduces the life and speed of the SSD.
Can a solution be written to the encrypted disk, a very large file that fills in the hard disk and then erases it for trimming and most hard disks to be marked as empty again? Will there be a trim operation, or probably many, many trim operations (one per sector) that could fill the trim buffer and fail?
Will defragmenting windoes 7 also realign the hard drive by sending the trim operations at slow speed for the hard drive to handle?
or I do not have to do anything and veracrypt will find that it is a ssd and only encrypted data and not the entire disk?
Can someone show me a solution in the veracrypt manual?

Command line – Mount the veracrypt partition at boot

I want to automatically mount a veracrypt partition at startup. But the problem is that I can not mount it from the command line because I entered this command:

# veracrypt -t --non-interactive -p any-password / dev / sdaX / media / veracrypt1 /

I get the following output:

The operation failed because of one or more of the following actions:
- Wrong password.
- Wrong volume PIM number.
- Wrong PRF (hash).
- No valid issue.

Enter the password for / dev / sdaX: 

and I have to enter the password again, but this time the partition hangs.

So I have to mount it from the command line, so I can set a script to be automatically mounted at startup.

Encryption – Can the government recover data from an encrypted ssd (veracrypt) that has been deleted?

Encryption – When is Veracrypt an acceptable solution?

To effectively manage security risks, a nonprofit organization must meet the following high standards.

  • Limit access to authorized personnel.
  • Sensitive data is only accessible to authorized employees.
  • Data integrity must be maintained.
  • Access to data must be verifiable.

Because some people work outside, it is important to securely store data both on the device being used and on data media such as DVDs and USB flash drives / drives.

In the past, the devices used TrueCrypt's full disk encryption. While the devices are withdrawn and renewed (donations), it is possible to inform the choice and the solution to protect the devices.

The employees are switched to Microsoft Windows 10 and OpenSUSE. The deployment of Windows 10 devices is limited for budgetary reasons. Not all devices support TPM. There are about 50 devices, the majority of which are non-Windows. In addition, the editions of Microsoft Windows are either Home or Professional.

In addition to Veracrypt, you can use Microsoft Bitlocker and LUKS. When searching online (for example, full disk options), the use cases for which the options are most appropriate do not appear to be clear.

For example;

  1. Should Veracrypt be limited to encrypting removable media?
  2. When should LUKS be considered?

Linux – How can I back up a Veracrypt file container?

I have a Veracrypt file with a capacity of about 100 GB on an external hard drive. I often change the contents of this container and want to know how to quickly save the updated file to a second external hard drive.

I'm aware that once I'm done with the work, I can copy the file directly to the second drive, but it will take a while for it to be big. Is there a way to update changed parts of the file with rsync, for example? I understand that the file is encrypted, which is not very useful given the comparison methods of copying.

How else can I do that?
