PC-3000 for HDD. How to unlock SED on WD SMR drives without a special board

Hello dear friends,

In June 2022, we released a new PC-3000 software version 7.1.x,  and one of the main features in this update is the SED unlocking option for new WD SMR families.

It means that now you don’t need to buy a special unlocked PCB to get the Service Area access on these drives anymore!

In this article, we describe how to use this option in practice.

PC-3000 Flash. Determination of Some Chip Parameters by ID

There are situations when you are reading a chip and see a detected Chip ID but it cannot be applied in the Task. As a result, it doesn’t allow to read the dump from the memory chip. Such behaviour may be if:

► The chip has physical damages or was overheated during the unsoldering process
► The memory chips reference book doesn’t have reading parameters for a certain Chip ID.

The information below will be useful when adding read parameters for new (unknown) memory chips and is intended for users who understand the main principles of NAND.
If you are new in NAND data recovery, we recommend studying these principles first.
Of course, you can try to find a datasheet for a certain memory chip and take reading parameters from there. But sometimes there is no possibility to find that datasheet or some parameters are missing there (not described).

Reading parameters detection is an investigation process and requires some specific knowledge. In this article, we’ll overview some ideas that can be helpful for you during this process. Anyway, we strongly recommend to contact our Technical Support Department if you get an unsupported NAND ID during your data recovery process.

PC-3000 Flash. SanDisk 200 GB mSD recovery

Hi everyone,

Today we are going to talk about the monolith cases produced by SanDisk, namely presented in the variations of 200 GB and 400 GB models.

Such cards were released a few years ago and remained the mSD cards with the highest capacity for years until the 256 and 512 GB modifications replaced them.

Nowadays, SanDisk Flash drives are one of the most complicated cases. Usually, they have a lot of additional issues and features that are typical only for SanDisk modifications.

Western Digital: Time-Limited Error Recovery

Bad sectors may appear because of the bad quality of the heads or due to small scratches on the surface of the platters. This problem is pretty up-to-date and sometimes, when you don’t have an opportunity to replace the heads or open the HDA on the Hard Drive, the only way to get the data is to be patient and reread all bad sectors one by one with different time-out settings in the Data Extractor.

But what to do if the WD disks have a lot of BAD sectors, and it is necessary to force the disk to complete the image?

PC-3000 HDD. How to Block Writing in Service Area in Seagate F3

Modern Seagate drives are very complex, and their hardware becomes more and more sensitive. If heads have issues, they can damage some critical objects in the Service Area during the internal FW processes. It may be a reason for data recovery time increase: we must spend more time and money to find new heads and fix bad system files. Is it possible to avoid that and block the writing in the Service Area? Let’s review that in this article.

PC-3000 Flash. The Tesla Car Case

Hello everybody!

Worn-out NAND Flash chips are a common issue when we are speaking about data recovery from USB Flash devices. Nowadays chips may have low quality even from the factory. Your pendrive may die less than in a month because of that. Unfortunately, such a tendency can also be seen when we are talking about other devices in which NAND chips can be used, for example, SSDs, mobile phones, and even modern cars!

PC-3000 Flash Spider Board Adapter. Automatic Pin Sequence Detection for the Monolith Bus Line

Dear friends,

If you have ever dealt with monolithic data recovery, you have definitely faced the necessity to find out the order of the bus line pins. Previously, if you had not known the order of the bus line pins and if you had no pinout map with all the information – such a case could not have been solved. But now things are easier with the new feature we showed at the ACE Lab Online Technology Conference 2021. From here on, with the Spider Board adapter and the latest PC-3000 Flash software update 7.5.11 you will be able to find out the order of the bus line pins!
