How to recover lost data from bitlocker protected partitions?

If users have data recovery tools, users can enter the backup recovery key(48-digit) within the recovery software and then users can use the recovery tools to extract the lost data directly.

If users don’t have data recovery tools, users can prepare one USB booting device to enter win pe os to decrypt the bitlocker protected partition and then copy the files directly to one safe place.

Users can find the bitlocker recovery key in the Microsoft account or search it in your local drives.
If the recovery key is completely lost, the chance of recovery is very low or impossible.

Dear Dolphin Data Lab Sales Team,

My name is Alessandro based in João Pessoa, Brazil. I am interested in purchasing the DFL-SRP All-in-One USB3.0 data recovery equipment and would like to request a formal quotation including shipping to Brazil.

Please provide full pricing details, shipping options (preferably via DHL or FedEx), and information on licensing, support, and future software updates.

Here is my information for invoicing purposes:
– Country: Brazil
– City/Postal Code: João Pessoa, 58040-260

If there are any recommended accessories or upgrade bundles available, I would be glad to receive your suggestions as well.

Also, could you please confirm whether the DFL-SRP All-in-One USB3.0 supports firmware-level diagnostics and repair for both SATA SSDs and NVMe SSDs?

I am particularly interested in knowing if it can recover drives with firmware corruption or issues at the controller level (e.g., unresponsive SSDs, bad translation tables, or microcode damage), especially for brands like Samsung, Kingston, and Western Digital.

Thank you in advance for your support.
Kind regards,
