Discover effective methods and step-by-step guides to recover data from your devices. Stay ahead of the game with our advice on retrieval data or storage security.
You encrypted a folder with EFS, then something happened — a reinstall, a profile reset, an accidental deletion, a drive moved to another PC. Now the files are back, but every one throws Access Denied. The data itself is not damaged; the private key that unlocks it is simply missing. This guide covers why that happens and how to recover and decrypt EFS-encrypted files with RS Partition Recovery.
BitLocker To Go is the same encryption engine as system-drive BitLocker, applied to removable media — external HDDs, SSDs, and USB flash drives. The unlock mechanics carry over from our guide to recovering an internal BitLocker volume, but removable drives fail differently in practice: no TPM to fall back on, a visible FAT32 partition that gets mistaken for the whole drive, and a higher rate of physical disconnects mid-operation. This guide covers what's specific to external and USB drives.
Recovering data from a BitLocker-encrypted drive isn't the same problem in every case. A forgotten password with the recovery key still in hand is a five-minute fix. A corrupted partition table on an encrypted volume, or a system drive that lost its TPM binding after a hardware change, is a different situation entirely — the volume is still there, but locating and unlocking it takes more than typing a password into Windows. This guide covers both, for the system volume (C) and any additional encrypted data volume (D).
Two drives have failed in your Synology SHR-1 array. DSM reports the storage pool as Crashed and states that data cannot be recovered. SHR-1 data recovery after a double drive failure is the subject of this article — and the situation is more nuanced than DSM's message suggests. Whether your data is recoverable depends not on the count of failed drives alone, but on how they failed and what state the surviving drives are in.
You replaced a 4 TB drive in your Synology SHR array with an 8 TB drive. The rebuild started, ran for a while — and then stopped. DSM shows Degraded, Crashed, or the progress bar has not moved in hours. The NAS may have become unresponsive entirely. This article covers data recovery after an SHR rebuild crash: what actually happened inside the array, how to read the current state without making it worse, and how to get your files back.
The NAS is dead. The drives are intact. You connect them to a Windows or Linux machine and either see a "You need to format this disk" prompt, or the drives are not visible at all. This is not data loss — it is an access problem. Unlike scenarios where the drives themselves fail, a dead Synology motherboard leaves the SHR volume data physically untouched. What you need to recover is not the data itself, but access to the multi-layered structure Synology uses to store it.
Two disks are gone in a single-parity array, or three in a dual-parity setup. Unraid cannot start the array, and even if it could, the data on the failed disks is mathematically unrecoverable through parity alone. This is the scenario where storage redundancy ends and data recovery begins.
The disk is physically present, SMART shows no errors, and the Unraid array started without issue — but one share is gone and the WebGUI shows the disk as Unmountable. This is a filesystem corruption event, and it is a different class of problem from a hardware failure.
