Samsung's T7 and T7 Shield are compact NVMe-based portable SSDs: fast, tough, and encrypted in hardware. That encryption is what makes recovery different, because the data can only be read through the drive's own controller, and with your password if you set one. We recover T7-series drives by mail when they stop being detected, lose files, or suffer connector damage.
The standard aluminum portable over USB-C, with hardware AES encryption and an optional password.
A rubber-coated, rugged version of the T7 with the same core design. It shrugs off knocks well, but the USB-C port and the electronics inside can still be damaged.
Adds a fingerprint sensor for unlocking alongside a password. If the sensor or its electronics fail, the password is the way in, so keep it.
The earlier Samsung portable SSD, also with hardware encryption and an optional password. It's an older internal design, but recovery follows similar rules.
A faster sibling with hardware encryption like the T7, so the same password and controller considerations apply.
Inside a T7 is an NVMe-based SSD, NAND flash and a controller, connected to a USB-C bridge. The drive is designed to encrypt data in hardware with AES whether or not you set a password, and the keys live inside the drive's own electronics. The flash chips on their own hold only encrypted data, so reading the chips directly, the way some unencrypted flash devices are recovered, generally isn't an option. The original controller has to be made to work.
If you set a password in Samsung's software, it protects the encryption key, and the drive won't unlock without it, in a lab or anywhere else. Most T7s ship formatted exFAT for use across Windows, Mac, and other devices, and exFAT is easily damaged by unplugging mid-write. Like other SSDs, the T7 may erase deleted data in the background through TRIM, so deleted-file recovery is time-sensitive.
A T7 that doesn't appear on any computer, or shows up without a usable capacity, may have a failed bridge, controller, or firmware. Because of the hardware encryption, recovery means repairing the drive's own electronics rather than reading the chips elsewhere.
A cable yanked sideways, or a drive dropped while plugged in, can crack or loosen the USB-C port. Symptoms range from intermittent dropouts to nothing at all. The fix is careful board-level repair that keeps the original controller intact.
Unplugging without ejecting, or a disconnect during a transfer, can damage the exFAT file system: folders vanish, or the computer asks to format the drive. The data usually remains as long as nothing new is written to it.
If password protection is on and the password is lost, the encrypted data can't be read. Samsung's software can reset the drive to remove the password, but resetting erases the data.
