Hey Ace team, great development!

The software for decrypt WD drives works excellent, and save a lot of time for every job.

Congratulations for this last version!

Hi !

Thank you very much for the great improvement as always.

Would you also give us an detailed description about the following ?

"Seagate F3
- Defect hiding algorithm has been improved"

My questions are
1. Newly improved defect hiding algorithm had been implemented by Seagate in new F3s ?
2. Pc3k now has a new function for hiding defects ?

Thanks in advance.

hello

I try the WD décrytage it works very well.

ACE is good work

Thank

Currently, the work with the encrypted Western Digital drives has become faster and more convenient. Previously, engineers could spend many days to recover data from the encrypted WD HDD, but now the issue with the encrypted drive can be solved within a moment.

The PC-3000 WD Marvell utility has a new mode to handle the Fully Encrypted Western Digital USB HDD. This mode provides “on-the-fly” software decryption which allows to work with the encrypted WD drives in the Data Extractor without transferring data on a healthy drive.

The following USB bridges are supported now:
INIC-1607E (Initio)
JSM-538
JSM-539 (Jmicron)
SW6316
OXUF943 (PLXTexnology)

The software decryption keeps the data transfer rate almost at the same level reducing it just for 10-15% for the modern computers.

For the external HDD with USB<->SATA controller board it is enough to take the drive from the case and connect it to the PC-3000. To work with the drives which have the embedded USB<->SATA bridge you have to either replace a compatible SATA PCB with ROM transfer or connect (solder) SATA interface to the original PCB. Also you can work via COM port without any additional actions, but COM port will significantly reduce the data transfer rate.

To keep safe the drive surface when you create a Data Extractor task you can run the WD Marvell utility and define encryption parameters only once. And then all encryption parameters will be saved and you will be able to use it the next time when the task is opened again. To start the data decryption “on-the-fly” you have to run the WD utility, create a new task in the Data Extractor and select the decryption as a reading mode in the Data Extractor parameters.

Question is bothering me:

I got encrypted SATA drive. If I copy with DE 3 heads to destination drive without checking "Decryption", and then copy 1 head with "Decryption" do I have some encrypted sectors and some decrypted sectors at the destination drive?

Thank you for your answer.

Peter

75% of sectotrs is encrypted, 25% would be decrypted. This image would be impossible to recover from, you must image all heads with decryption selected to recover files, or image as encrypted then decrypt over some compatible bridge

Thank you AJ2008.

It is kinda logical, maybe I just needed to hear confirmation.
