SSD Data Recovery
JMicron JMS583 USB-to-NVMe Bridge Data RecoveryORICO external enclosures / Sabrent enclosures / JEYI enclosures
The JMicron JMS583 is the bridge chip inside most external NVMe SSD enclosures. When your external SSD stops working, the first step is removing the NVMe drive from the enclosure and connecting it directly to an internal M.2 slot. In most cases the SSD is fine and the bridge chip has failed. Our Austin lab uses board-level diagnostics and NAND-level techniques for JMicron JMS583 USB-to-NVMe Bridge recovery.

How We Recover JMicron JMS583 USB-to-NVMe Bridge SSDs
Firmware-Level Recovery
The PC-3000 does not yet have full Active Utility support for the JMicron JMS583 USB-to-NVMe Bridge. Recovery relies on manufacturer-specific diagnostic modes, service pin access, and NAND-level techniques.
We monitor PC-3000 firmware updates for new controller support. When utility support becomes available, firmware-level recovery will be the preferred path for this controller.
Chip-Off Recovery
Chip-off is not viable for the JMicron JMS583 USB-to-NVMe Bridge due to hardware encryption or architectural limitations. Recovery depends on accessing the controller through firmware-level tools or manufacturer diagnostic modes.
Not an SSD controller; this is the bridge chip in most external NVMe enclosures. N/A for chip-off.
Pricing
SSD firmware and logical recovery for the JMicron JMS583 USB-to-NVMe Bridge typically costs $300 to $500. Controller-level failures requiring advanced diagnostics are $500 to $1,500. Chip-off recovery, when viable, is $1,500 to $2,500.
See our full pricing breakdown for details. Our No Data, No Fee guarantee means you pay nothing if we cannot recover your files.
Hard Drive Data Recovery Standards & Verification
Our Austin lab operates on a transparency-first model. We use industry-standard recovery tools, including PC-3000 and DeepSpar, combined with strict environmental controls to make sure your hard drive is handled safely and properly. This approach allows us to serve clients nationwide with consistent technical standards.
Open-drive work is performed in a laminar-flow bench filtered to 0.02 µm, verified using TSI P-Trak instrumentation.
Transparent History
Serving clients nationwide via mail-in service since 2008.
Media Coverage
Our repair work has been covered by The Wall Street Journal and Business Insider, with CBC News reporting on our pricing transparency. Louis Rossmann has testified in Right to Repair hearings in multiple states and founded the Repair Preservation Group.
Aligned Incentives
Our "No Data, No Charge" policy means we assume the risk of the recovery attempt, not the client.
Technical Oversight
Louis Rossmann
Louis Rossmann's well trained staff review our lab protocols to ensure technical accuracy and honest service. Since 2008, his focus has been on clear technical communication and accurate diagnostics rather than sales-driven explanations.
We believe in proving standards rather than just stating them. We use TSI P-Trak instrumentation to verify that clean-air benchmarks are met before any drive is opened.
