Today we would like to talk about RAID arrays with lost configuration and how to extract data from them. This article will be useful to both digital forensics experts and data recovery engineers. Let’s start with understanding what a RAID is in the first place.
RAID. What is it?
RAID is a Redundant Array of Independent Drives. The system shows it as a virtual storage device with block access. In essence, RAID is a virtual drive.
As you well know file systems play a crucial role in data recovery. And there were a lot of them developed during the past 30-40 years. Some file systems are specific to a particular operating system. For example, HFS and HFS+ have been used in Apple devices for over 30 years.
APFS was developed from scratch and became the standard file system for Apple devices since 2017.
How often do you use Data Extractor RAID Edition to recover data from RAID arrays? How often do you use statistics to define the configuration and recover data from this configuration?
We won’t dig too much into the merit of statistics for data recovery. Today we would like to tell you about cases where RAW recovery and statistics on RAID members show nothing.
To recover data from damaged drives, it’s often necessary to use donor PCB or/and donor heads on the patient drive. But where and how do you get such donor drives?
The easiest way is to use the “Search donor drives” button in the PC-3000 utility. In today’s article, we tell you more about this button and how to use it to find donor parts for your patient drives. Continue reading
We keep receiving requests about how to restore the drives with bad areas in order to use them in the future. In this article, we are going to review the restoration process of WD Marvell drive which worked in DVR for a long time, got reading issues and was not able to be used for data storage.
Please note that all actions in this article are intended for HDD repair only (NOT FOR DATA RECOVERY).
Time Machine is the standard backup software application in macOS. Time Machine makes hourly backups of the last 24 hours, daily backups for the past month, and weekly backups for everything older than a month. It makes backups until the volume runs out of space. Often these backups are stored on a disk with HFS+ file system.
In this article, we will discuss the details of data storage in the Time Machine and how to use it in the data recovery process.
From time to time we have to work with formatted drives. Most file systems have special rules for data recovery from formatted drives. Sometimes, we work with formatted RAID arrays. For RAID cases, there are different rules for data recovery, but the main principles are still the same.
In 2018 our we received a lot of new NAND chips that were unreadable by the PC-3000 Flash reader of versions 1.0, 2.0 and even 3.0 without extended power supply adapter. Why that is the case, we will explain in today’s article!
As you all know, ONFI NAND chips usually require 3.3V. It’s a standard voltage value, which was used by default on almost all NAND Flash for the last 15 years. Continue reading
Today we will talk about Silicon Motion SM2236G — one of the most popular Compact Flash card controller.
Have you ever faced the situation when something happens during the drive’s reading proccess and you have to create a new task? In such a case, you will lose everything you’ve read before in Task 1. So, is there any chance to save it?
In this article, we will show you how to transfer the read data from one task to another.
