No matter you are using QNAP, Synology, Western Digital, NETGEAR, etc, the file system of the device is Ext4. And there are times that you may delete files from NAS or format them when you are trying to upgrade it to a bigger one. How can you get back data from your NAS Ext4 drives? EaseUS RAID recovery software can help.
What if you have data loss from Ext4, Ext3, and Ext2 Linux partitions because of accidental deletion or other operations? The easiest way to recover data from Ext4, Ext3, and Ext2 Linux partitions in Windows 11/10/8/7 is using good data recovery software. There are lots of data recovery software available in the market, but most of these tools don't support the Ext4 file system, making Ext4 data recovery impossible with such software.
Step 1. Run EaseUS Data Recovery Wizard. Select the partition where stored the lost files and click "Scan". EaseUS data recovery software supports parition recovery with FAT(FAT12,FAT16,FAT32), exFAT, NTFS, NTFS5, ext2, ext3, HFS+, and ReFS file system.
Step 3. You can preview files before recovery. Then, select all desired data and click "Recover" to restore files from existing partitions. Do not save the files to the partition where you lost the data.
You can access and recover Linux Ext4 data on a Windows computer easily if you have a fast and reliable data recovery tool. Linux has built-in support for Windows NTFS partitions, so the Windows operating system can not directly read the Linux partition. Thus, the data recovery software is a must-have tool for you. If you still have problems, you can turn to a manual RAID recovery service.
Officially one of the key features of the 2.4 kernel release, ReiserFS has been available as a kernel patch for 2.2.x SUSE kernels since version 6.4. ReiserFS was designed by Hans Reiser and the Namesys development team. It has proven itself to be a powerful alternative to Ext2. Its key assets are better disk space usage, better disk access performance, faster crash recovery, and reliability through data journaling.
The wiper.sh script trims read-write mounted ext4 or XFS file systems and read-only mounted/unmounted ext2, ext3, ext4, or XFS file systems. Do not use wiper.sh on the Btrfs file system as it may damage your data. Instead, use /usr/share/btrfsmaintenance/btrfs-trim.sh which is part of the btrfsmaintenance package.
Raise Data Recovery is designated for data recovery from Windows, Linux and Mac file systems (such as NTFS, FAT, ExFAT, HFS+, Ext2, Ext3, Ex4, RaiserFS, JFS, XFS, UFS, UFS2 etc.) and raw recovery technique.
The software automatically selects data recovery methods designated for the purposes of your operating system and conveniently recovers lost information from your computer. Raise Data Recovery employs careful algorithms for source analysis and powerful search and recovery mechanisms similar to those used in professional series. At the same time, it does not require special technical knowledge or skills. Raise Data Recovery is a top-level software wrapped in a simple and intuitive wizard-style interface.
The software doesn't require any extra user actions to start the process of data recovery. After you simply click on the button for storage scan, the program will run over the storage space delivering all found folders and the intact files that have been contained inside the file system.
The journaling function reduces the time required to check the hard drive for inconsistencies after a failure from hours (or even days) to mere minutes, at the most. I have had many issues over the years that have crashed my systems. The details could fill another article, but suffice it to say that most were self-inflicted, like kicking out a power plug. Fortunately, the EXT journaling filesystems have reduced that bootup recovery time to two or three minutes. In addition, I have never had a problem with lost data since I started using EXT3 with journaling.
The journaling feature of EXT3 can be turned off and it then functions as an EXT2 filesystem. The journal itself still exists, empty and unused. Simply remount the partition with the mount command using the type parameter to specify EXT2. You may be able to do this from the command line, depending upon which filesystem you are working with, but you can change the type specifier in the /etc/fstab file and then reboot. I strongly recommend against mounting an EXT3 filesystem as EXT2 because of the additional potential for lost data and extended recovery times.
a) xfs access is faster than ext4 in most cases.b) xfs meta data recovery is lacking. As the partition came close to being full, one could expand an xfs file system, but if one could not, performance and data recovery suffered if there was an unscheduled shutdown.
The best free data recovery software for Mac available online is described below. These five applications vary in their characteristics. However, all share one commonality, they are free, and therefore useful for the casual user.
1. Disk Drill for Mac The best data recovery software for Mac that you can add to your digital toolbox is Disk Drill. Since its arrival in 2010, this free application has been making data recovery services angry by empowering regular home users to get back their lost data in a few steps, saving them a lot of money in the process.
Disk Drill for Mac combines powerful recovery features with a user interface Apple could be proud of. The latest version of the versatile mac file recovery software goes beyond basic recovery functionality by including an entire collection of data management and protection features designed to help Mac users avoid data loss.
PhotoRec is not the most powerful free Mac data recovery tool, but it has the advantage of being open source. This basically means that not only the application but also the source code is available to the public.
This free file recovery Mac app uses a powerful technology known as file carving. This method consists of two steps. Firstly, it searches for the data block or cluster size. If the file system is not corrupted, this value is obtained from the superblock (ext2/ext3/ext4) or volume boot record (FAT, NTFS). If this is not possible, the app checks each sector of the device, and using the first ten files found, it calculates the block or cluster size.
The free version is limited to a maximum of 2GB of restored data. This free data recovery software can recover data from Mac notebooks, desktops, hard drives, USB drives, SD cards, memory cards, digital cameras, etc. It works on internal HFS+ drives, and on FAT/FAT32 file systems used in USB flash drives and external hard drives connected to an Apple computer.
Selecting the best Mac data recovery software can be a challenge since there are so many seemingly great options available. To help you narrow down available data recovery software for Mac, here are the most important selection criteria you need to focus on:
The best file recovery software apps for Mac have been perfecting their data recovery algorithms for years to quickly and reliably find all deleted files. Since data restore is a time-sensitive task, it makes sense to select the most capable app available and get all deleted data back on the first try.
Mac users typically format disks and volumes using Apple File System (APFS), HFS+ (Mac OS Extended), MS-DOS (FAT), FAT32, and exFAT file systems, so make sure to select a data recovery software application that supports them. If you also want to recover Windows drives, the application needs to support NTFS.
There are thousands of file formats in existence, and no data recovery software supports every single one. However, some solutions can recover virtually all file formats you are likely to come across, and we highly recommend you prioritize them over applications that can recover only a handful of commonly used file formats.
While all data recovery software apps for Mac can recover deleted files, some have many extra features that make the recovery process easier and more likely to end successfully, such as the ability to preview deleted files, recover files from failing, corrupted, and formatted devices, or scan RAW and lost partitions. You may even come across recovery apps that double as capable backup solutions, giving you more value for your money.
We recommend going with Disk Drill Data Recovery Software for Mac, as it delivers on its data recovery odds. This awesome data recovery tool is backed up by good looks, a more intuitive user interface, and a ton of free disk tools that may become handy for any user.
There are Mac data recovery software applications that are completely free, but most come with certain limitations and require their users to purchase a license to remove them. The cost of a Mac data recovery software license varies greatly, but the average is around $100.
TestDisk is a free and opensource, command-line data recovery tool that is used to recover data from deleted or lost partitions. Further, you can use it to revive non-bootable partitions which can be caused by factors such as accidental deletion of partition tables, and malware attacks to mention a few.
It seems to me it is a limited recovery tool as it needed to be installed in the faulty computer in order to recover data. Probably it would be better that this software was created to be installed in an external bootable device, such as a dvd or flash drive.
TL;DR: Despite its steep price and underwhelming customer support, Stellar Data Recovery is still a great data recovery software application. Just keep in mind that less expensive yet more capable alternatives do exist.ParameterScore (10 points)User Friendliness
