PC-3000 SSD. How to plug Samsung 840 EVO / PM851 through terminal

Posted on 12/11/2015 by ACELab team

Starting from the version of PC-3000 SSD 2.0.3, it become possible to recover Samsung 840 EVO, Samsung PM 851 and Samsung 850 Pro drives. One of the main problem of this drives – is a very-very bad quality of NAND memory chips. As the result – a huge number of ECC errors and NAND degradation.

At the same time, this family of Samsung SSD has very complicated internal structure of Firmware with full encryption. Besides, in this family of SSD drives for working with Technological Mode, we need to use terminal connection, because ATA commands become blocked in case of FW internal corruption. It means that if we need to switch drive in technological mode, we should plug PC-3000 terminal.

PC-3000 HDD. How to solder a SATA-adapter to the USB Western Digital drive

Posted on 12/02/2015 by ACELab team

WD_USB_003

As you know Western Digital drives have a SATA or an USB interface (2.0 or 3.0).

For work with the USB drives better to connect them to PC-3000 via SATA, ’cause USB connection have a restrictions and a lot of preparations can’t be performed via USB interface.

Of cource you can use the compatible SATA board for USB WD drives based  on USB v. 2.0.

But what about USB drives based on USB v. 3.0…

Or maybe you haven’t  or don’t want to purchase a compatible SATA board for your USB WD drive (on USB v. 2.0)

PC-3000 DE. Data Extractor quick reference

Posted on 11/23/2015 by ACELab team

People who apply for data recovery services, are often asked to return the data from the partition that “suddenly disappeared”.

Reasons of data loss can be very different: power and microcode failures of drive, failed experiments with drive reallocation, viruses and so on. In this article we will try to understand why we can’t see the data and how it can be restored via DataExtractor features.

PC-3000 for HDD. Where and how to short Seagate F3 drives

Posted on 11/20/2015 by ACELab team

As you may know, first step of diagnostics on Seagate drives is to check terminal output after power on and check is drive able to read system files.

YhrS9BS

But there a lot of firmware errors when you can’t access terminal – got T> string after pressing Ctrl+Z. In terminal log you have last message something like:

LED:000000CC Faddr:0026A86F

or

LED:000000EE FAddr:00358846

At this situation you should try to short read channels.

PC-3000 Flash. Compact Flash recovery. SM2234H

Posted on 11/04/2015 by ACELab team

Compact Flash cards – are the most fastest memory cards in the market. The main secret of CF – is a very powerful controller, which has direct access to several physical memory chips, which are placed on the CF PCB. The architecture of Compact Flash controllers is much closer to SSD CPU than to common USB Flash drive controllers.

One of the most popular Compact Flash card controller is Silicon Motion SM2234H. Usually this controller works with 4 physical memory chip, and provide a high speed of reading and writing operations.

When customer get the recovery task based on this controller, he make a wrong steps of recovery and usually never get a good result. In this article we will try to explain, how to deal with this controller, and what exactly you should do for getting user data from such case!

PC-3000. Database. Problem with the folders

Posted on 10/30/2015 by ACELab team

Sometimes PC-3000 database can get a problem with the folders location.

One or more folders from the root are moved to the other place.

For example on this screenshot you can see that HDD profile folders are moved in to the SSD tool profile folder:

database_before

Such behavior caused by problems with database service in OS or critical shutdown of this DB.

How to solve such problem?

PC-3000 DE. Data Extractor RAID Edition. How to build RAID array with virtual machines in VMFS volume

Posted on 10/29/2015 by ACELab team

Using Data Extractor RAID Edition, we are able to identify special RAID configurations and extract data from virtual machines on RAID arrays.

Data Extractor RAID Edition supports SPECIAL-VMFS level for manipulations with VMFS spanned across multiple disks
These virtual machines created with VMware or other products typically use virtual disks.
The virtual disks, stored as files on the host computer or on a remote storage device, appear to the guest operating systems as standard disk drives.

We will show in this topic how to assemble RAID with virtual machines on 4 disks with VMFS volume.
We do this using a little knowledge of the RAID array architecture which we then combine with the metadata autodetection of Data Extractor RAID Edition.

PC-3000 Flash. How to recover data from a monolith (microSD card)

Posted on 10/12/2015 by ACELab team

Nowadays a lot of modern NAND flash devices use a new type of architecture, where the interface, the controller and memory chips are integrated into one common ceramic layer. We call it Monolithic structure.

Until recently, all memory cards like SD, Sony MemoryStick, MMC and others, contained a very simple “classic” structure with separated parts – a controller, a PCB and a NAND memory chip in the TSOP-48 or LGA-52 package. In such  cases, the full process of recovery  was very simple – we just unsoldered the memory chip, read it in PC-3000 Flash, and made the same preparation as with common USB Flash drives.
