Case:After the customer’s hard disk was shut down normally, the hard disk was not recognized the next day. Solution:The power connection is the F -class on the terminal. Most of this phenomenon is caused by the problem of magnetic heads. Only the opening of the magnet was opened. After finding a model, the place of…
Case:Mr. Song’s hard disk data was lost. Through online consultation, he agreed to recover, but hoped that we could come to the door to pick up the disk. Solution:After the engineer retrieved the hard disk, he began to detect. He found a large number of bad sectors. It was decided to do a full -scale…
Dell and computer forensics specialists Access Data have released their new Dell Digital Forensics Platform and Forensic Toolkit 4.0 at the International Security and National Resilience (ISNR) exhibition in Abu Dhabi.
“Today’s launch of the FTK 4.0 is a significant milestone that marks the next phase of our efforts here in the Middle East. This release, which is unlike any other previously seen in the region, enables court-cited digital investigations and is built for speed, analytics and accuracy,” said Simon Whitburn, VP International Sales at AccessData.
The new forensics tool expands on AccessData’s existing solutions, to provide a turnkey solution for a wide range of investigative operations, including processing of forensic images and email archives; registry analysis; file decryption, password cracking, image creation and report building.
AccessData offers two expansion modules with the new version-Cerberus, a malware triage technology that provides threat scores and disassembly analysis to determine both the behaviour and intent of suspect binaries, and Virtualization for relationship analysis in multiple display formats, including timelines, cluster graphs, pie charts and more.
“We developed the combined platform in response to significant customer demand, in large part from this region. Dell has worked with us to provide a turn key digital forensics solution that enables our clients to get mobile very quickly. Partnerships with such leading organizations will play a pivotal role in our expansion in the region,” said Whitburn.

Drives presented for recovery sometimes have some heads or surfaces damaged (physical damage). The problem is severe enough for the drive to stop working in its native system. However, with the latest upgraded Data Compass DCEXP utility, it is possible now (before installation of MHA replacement) to create a copy of data using the remaining good surfaces or drive heads; small files can even be recovered directly.
What’s more, this procedure will also be essential in cases:
1. When the drive is having read instability problem: by reading the surfaces one by one, it greatly reduces the seek time & times, smoothes the reading of the data, thus in some cases the original “damaged” head or surface becomes available, and users will then have no need to perform a risky MHA replacement.
2. When users have only a donor MHA with some heads damaged also: we can use the native head to read the available data first and then replace it with the donor one for reading the available data; if these two MHAs happen to be a complement to each other (for example native MHA with head 1 damaged, and donor MHA happens to have head 1 remained good), even in fact we don’t have/use a good MHA at all, we can recover all the data on the drive.

Note: The following free hard disk drive utilities and diagnostic tools are only for Samsung Hard Disk Drives. Using any of these utilities on a hard disk drive that was not manufactured by Samsung will have adverse effects on that hard disk drive.
Disk Manager provides support for Dynamic Drive Overlay, which will allow older BIOSes to support large-capacity hard drives. Disk Manager can also partition the drive. (Note: Registration information needed for downloading)
There are three utilities depending on the model of your hard disk drive for diagnosing hardware problems and performing low-level formats:
SHDIAG is a hardware diagnostic for older Samsung hard drives. Backing up data before using SHDIAG is strongly advised.

HUTIL is made with the aim of testing a Samsung hard disk drive while it is installed inside a PC, regardless of the status of user’s operating system. It is a good idea to test drive that is having problems with HUTIL to see if it is truly defective to avoid possible unnecessary troubleshooting or factory service. HUTIL includes EraseHDD, a utility that will perform a low-level format including the partition table and Master Boot Record.

Data Advisor is a free hard disk drive diagnostic utility available from http://www.ontrack.com/dataadvisor/. Data Advisor quickly assesses the health of your hard disk drive, file structures, and computer memory by identifying problems that could cause data loss. Don’t worry if you can’t boot your system to Windows; Data Advisor is self-booting, so it runs even when your system won’t.
Note: Ontrack DataRecovery is not associated with Samsung, Inc.
The basic idea of RAID (Redundant Arrays of Inexpensive Disks) is to combine multiple small, independent disk drives into an array of disk drives which yields performance and recoverability exceeding that of a Single Large Expensive Drive (SLED). Redundancy is also provided (unless RAID 0) which allows easy and often automatic recovery from hard disk crash. With the reduction in price of ATA and SATA drives it is often a good idea, even for desktop computers, to setup a RAID 1 system to allow you to function in the event of hard disk failures. In RAID 1 two hard disks (or portions of them) mirror each other. RAID 1 is essential for our environment. I have tested both Windows software RAID facility as well as Linux RAID capability. Linux RAID support is way superior to Windows and should by itself be the reason to switch to Linux. I have given 4 reasons to support my claim below.
Linux supports RAID on block devices. So you can setup RAID between two partitions on the same hard disk or even on two RAID 0 arrays, effectively creating RAID 10 array. Windows simply supports RAID 0 and GBOD (known as linear on Linux) only for non-server users. Linux support all RAID variants. Even Windows server doesn’t support the intermediate RAID variants.
In Linux as well as Windows you can create RAID arrays spanning machines.
In Windows you cannot install the operating system on RAID. In Linux you can even install the operating system on RAID file system. This means if one of the hard disk dies you can easily boot from the other hard disk (assuming you transferred the MBR earlier).
If you have spare hard disks, Linux will automatically configure it and add to the RAID array, should one of the RAID disks fail. This is to my knowledge not possible in Windows.
Linux RAID can be easily configured during installation. All the partitions (/, /opt and even swap) can and should be RAID enabled. Windows RAID is harder to configure and is done after installation of the OS, from disk management.
Comprehensive RAID support by itself (not to mention security) should be reason enough for SMB servers to switch to / use Linux.
These days, more and more people are using computers to store memories, important documents, and various other bits of information that may need to be kept for long periods of time. Backing up a PC is essential for keeping long term (or even short term) documents around. Whether you accidentally delete a file or lose…

What lifetime can be expected of the typical hard disk? Or are there big differences between different types? And does it make a difference if it is used heavily instead of never being connected to system (for example serving as a backup medium)? Solution: What lifetime can be expected of the typical hard disk? The…
