VMFS Data Recovery Software is To Be Released

VMFS has an automated file system with a hierarchical directory structure, optimized for virtual machines in a clustered environment. It has locked management and distributed logical volume management to across multiple partitions and dynamically expand data stores, the system can quickly restore the entire virtual machine state in a single directory.

VMFS has automatic and intelligent cluster file system. It is so optimized that can be used in virtual environment. Traditionally only a file is allowed to be read for a server at a time, VMFS can read/write multiple files at a time using shared storage.

The composition of VMFS volumes is derived from the two-tier architecture of VMFS: file data blocks and subsystem data blocks. The file data block is selected when the volume is created, and has a block size of 1 MB, 2MB, 4MB, or 8MB. Subfile data blocks are further divided into smaller blocks within the file system, reducing the generation of internal fragmentation by multiple very small blocks.
Usually, if the VMFS volume is formatted as a 1MB-sized block, then multiple 64KB blocks are used to satisfy the storage requirements for small files. So that each VMFS-3 volume will have multiple blocks of 64KB size separated by the main block.

The software uses efficient data structure and analysis algorithm, reading the original sector data and re-constructing lost and damaged directories and files in memory.

RecoveryRus is Releasing NetAPP Data Recovery Software

As RecoveryRus researches deeper into NETAPP, we have made great progress on RAID4 and RAID DP based WAFL storage recoveries. We can now extract files under NAS and SAN systems, then we have NETAPP that supports AID4,RAID DP,NAS,SAN, deleted Vol, deleted LUN.

WAFL file system has 3 meta-data files:
1.inde file – contains the inodes for the file system
2.block map file – identifies free blocks
3.inode map file – identifies free inodesa

RecoveryRus is Releasing Data Recovery Software For Qnx

The QNX4 file system is the default operating system for QNX Neutrion, which uses the same disk structure as the QNX4 file system, provided by fs-qnx4.so, and is automatically loaded when using the devc- * load QNX4 file system. It uses extent-based, with fingerprint bitmap allocation, effectively preventing data loss, and easier to recover.

POSIX file system advantages:
Robustness: All sensitive information is written on disk
Disk signatures and special key information can recover data even when the disk is damaged
Support 505 text file names
Support multi-threads
Customer-driven priority
Consistent with QNX4 disk structure

QNX 4 disk structure

1.Partition components

A QNX 4 file system can occupy a single disk (such as floppy disk), it can be a partition on the disk.
loader block: The first data block in the disk partition. It contains the boot code for loading the BIOS and loads the OS image from the partition. But the disk does not contain the partition that is the first physical block in the disk.
root block:It is the second block in the partition. It has a directory structure and contains the following files:
The root directory of the filesystem(usuall /) :The root of the file system (usually /)
.boot :The boot OS image is stored in this file
altboot :alternative OS images
bitmap block: A group of consecutive blocks after the rook block. It contains one of the partitions for the image. A bit corresponds to a block (usually 2M). When this bit is 0, it means that the block is not being used.
root directory:An ordinary directory, but contains the following characteristics. It contains the following specific files:
/. and /.. :A point to the connection with the directory
/.bitmap :A read-only file that contains a partitioned bitmap image ( same as bitmap block) 。
/.inodes :A collection of inode objects. The first object is reserved for the information area. The first is
IamTHE.inodeFILE 。In the floppy disk / RAM accounted for a block in the disk accounted for 16 blocks.
/.logfilenames :An optional file that holds more than 48 characters for the file name/.boot :system image
/.altboot :system alternative image
・ other directories , files , free blocks , etc :Other directories, files, free blocks, etc.

2 .Directories
A directory is an ordinary file that contains a set of directory objects.

Usually the first object is /. file, the second is / .. file etc. Each directory object either correspond to a file or point to an object in the /.inodes file.

In the QNX 4 file system, ordinary files and directories are stored on a set of consecutive disk blocks. The directory entry that keeps the file will track the extension. The file system will use a linked list to save the extent of the information. When a file requires more space, the file system will attempt to expand the disk continuously. If not, it will be assigned in other places a new extent. The file system will allocate more space than the required space to prevent multiple files at the same time when writing a number of non-continuous space. When the file is closed, the extra space will be released.

RecoveryRus is Releasing Its Unique Platter Holder Smart

RecoveryRus has decided to release this unique platter holder to the world to help all clean room data recovery engineers during their platter swap cases.

HDD Platter Holder Smart is like one helping hand during platter swap, it supports both 2.5″ and 3.5″ hard drive platters. When engineers are trying to swap multiple platters, it is usually not possible to swap all platters at one time, they need to put the platters in one correct way at one correct place.

Some people use plastic air blower to put the platters, it is ok, but not professional and has a risk of touching the platters. Some people don’t even have methods to put the platters, they just simply remove the platters of good drives and put on the desk, this will destory the good drives at a big chance and increase the cost of donors.

To solve above problems and issues, RecoveryRus designed and manufactured this easy-to-use platter holder so that users can simply put the platters on his holder with our unique platter exchanger. This will definitely help to save donor cost and make the swap process more smooth and successful.

RecoveryRus is Releasing its Unique Smart Hard Drive Platter Exchanger

Physical data recovery case is very common case in most data recovery labs, this kind of case is mostly from 2.5″ hard drives in laptop or directly external portable hard drives.

Sometimes it is a must to swap the platters to recover lost data. For example, when the hard drive spindle motor is dead or when the hard drive inside is severely contaminated or when the new drive has new design of heads and platters, without swapping the platters, users cannot swap heads.

In the current data recovery market, there’re few platter exchangers and some engineers have also their own DIY platter exchangers. But not so easy to use and has high risk of losing the platters during platter swap if wrong operations.

RecoverRus has been working in data recovery field to offer high-level of recovery services for a long time and based on our recovery experience, the Hard Drive Platter Exchanger.Smart was designed and manufactured. When users buy this platter exchanger, RecoveryRus will share the special tip and even some secrets of platter swap to add to your physical recovery success rate.

Hard Drive Platter Exchanger.Smart is now available to the world and it will be shipped by DHL express to worldwide users.
