• WD Portable SMR Hard Drives with MCU Encryption

    by Jun 22, 2021

    Each year, we see new hard disk drive models released and each year, we see the firmware get more complicated or the drive security increased by the manufacturer. Two of the most common portable drives we see by Western Digital are the 2TB Charger and the 4-5TB Spyglass models. Both drive families already presented specific […]

  • The Case for Flat Rate Data Recovery: A 2020 Retrospective

    by Jan 31, 2021

    Last year was our busiest year to date at Blizzard Data Recovery, with a 66% increase in data recovery cases since 2019. As I gathered up the numbers for this 2020 retrospective, I remembered a number of blog posts I’ve seen from other companies “warning” about flat rate data recovery pricing. Some people make claims […]

  • Flash Drive Recovery for CBM2091 Controller

    by Nov 16, 2020

    We recently completed a flash recovery case where the drive was not repairable, and a chip-off recovery was not, at first, successful. Once Clint had determined that the device was not physically repairable, it came to me to dump the memory chip to attempt a logical recovery. The controller on the device was a Chipsbank […]

  • Portable WD SMR Drive – Data Recovery

    by Oct 06, 2020

    Most modern portable hard disk drives use relatively new technology, first implemented in the early 2010s, called shingled magnetic recording (SMR) to write data to the platters. SMR can achieve higher areal density than the older method of perpendicular magnetic recording (PMR, sometimes referred to as conventional magnetic recording or CMR) which simply means more […]

  • Convert a Lexar Flash PCB (SM3267L-AB) to Two Chips

    by Jul 21, 2020

    We recently completed data recovery for a customer with a 32GB Lexar Jump Drive which had taken an impact while plugged into a USB port, and, as is the case with many of these Lexar flash drives, the impact flexed the circuit board enough to lift the controller (Silicon Motion SM3267L AB) and tear solder […]

  • Data Recovery Lab Best Practices – For Hard Drives

    by Jul 15, 2020

    In the past few years, there has been a spike in new data recovery labs opening up across the USA and other countries. In speaking with some DR business owners and researching topics on data recovery forums, it looks like a number of computer repair shop owners are looking for a new business, and data […]

  • Flash Monolith Pinout Analysis and Recovery

    by Mar 05, 2020

    When it comes to flash memory devices – whether USB flash drives or memory cards like SD and MicroSD – there are two main types of construction: surface-mounted technology (SMT) and monolithic. SMT type devices are made of distinct components soldered to a printed circuit board, which requires a certain amount of space to fit […]

  • Western Digital USB Hard Drives – Cross Reference

    by Jan 28, 2020

    In this post we provide you with some useful insight to help determine what model Western Digital drive might be inside a particular model of enclosure. We have included pictures of the shell to help you identify these drives quicker when searching for a matching donor. If you have done some research you have probably […]

  • Platter Swap – Clean Room Data Recovery

    by Dec 08, 2019

    It’s a common misconception that a large percentage of hard drive data recovery cases involve removing platters. The truth is platter swapping is only necessary in a low percentage of recovery cases for most data recovery labs. For mechanical failures, the most common reason for in-lab recovery service is removal and inspection of the read/write […]
