start your recovery

why your data isn’t gone when the drive fails

Even when an HDD:

  • won’t mount,

  • isn’t detected,

  • makes clicking/buzzing sounds,

    the data on its platters is often still intact.

Our clean‑room tools let us repair or bypass failed components (heads, PCB, firmware) and image the drive sector‑by‑sector to safely rebuild your files.

devices & failures we recover

  • any brand, make, or model (Seagate, WD, Toshiba, Hitachi, etc.)

  • any interface: IDE, SATA, SAS, USB, NVMe-to-HDD hybrids

  • any operating system: Windows, macOS, Linux

  • any generation: from legacy drives to the latest helium HDDs

  • any failure: mechanical, electronic, accidental deletion, malware, file-system corruption, encryption issues

common hdd problems we solve

  • seized spindle motor – persistent buzzing or no spin-up

  • damaged PCB (printed circuit board) – no power / no detection

  • bad sectors – repeated read errors, slow access

  • firmware corruption – e.g., classic Seagate 7200.11 issues

  • file‑system corruption – volume mounts but files are inaccessible

  • drive detected but no data accessible

  • drive not detected at all

  • deleted / reformatted drives

  • encrypted drives (BitLocker, FileVault, etc.) – recovered with proper keys

signs of a failing hdd

  • Clicking, grinding, or buzzing noises

  • Frequent crashes or freezes

  • Very slow reads/writes

  • Corrupted or disappearing files

  • SMART errors / bad sectors

  • Drive not detected

  • Computer won’t boot

what you should do (and NOT do)

  • stop using the drive immediately to avoid overwriting or further mechanical damage.

  • contact a professional recovery lab before further attempts

  • don’t run chkdsk, fsck, or DIY tools - these can worsen the damage

  • don’t open the drive - HDDs are sealed and require a cleanroom
