helium hard-drive data recovery
all models, all failures
san jose & bay area experts
if it lived on a helium hard drive, we can bring it back
Helium hard drives offer large capacities and improved efficiency - but they’re still mechanical devices, and like all HDDs, they can fail.
At Kotar Data Recovery, our San Jose cleanroom lab specializes in helium hard-drive recovery for any brand, model, or failure type.
We combine 25+ years of expertise with advanced diagnostic and repair tools to safely restore your data.
why your data isn’t gone when a helium drive fails
Even when your helium HDD:
isn’t detected,
makes clicking, whirring, or buzzing sounds, or
overheats and shuts down -
the data on its platters is often still intact.
Our engineers use clean-room tools to repair or bypass damaged components (heads, PCB, firmware, or seal-related issues) and image the drive sector-by-sector for safe reconstruction.
devices & failures we recover
any brand or model: Seagate, Western Digital, Toshiba, Hitachi, etc.
any interface: SATA, SAS, IDE, USB, or hybrid drives
any OS: Windows, macOS, Linux, NAS file systems
any generation: from legacy to latest helium-sealed HDDs
any data loss: mechanical, electronic, logical, accidental deletion, corruption, or malware
common helium hard-drive problems we solve
mechanical failures: seized spindle motor, damaged heads
electronic problems: faulty PCB or power-related issues
firmware corruption: firmware bugs blocking access
bad sectors: unreadable areas preventing data retrieval
overheating damage: thermal failure degrading components
physical damage: impact or vibration affecting internal alignment
power surges: sudden current spikes damaging circuitry
manufacturing defects: design or assembly faults
file-system corruption: files inaccessible or missing
deleted / reformatted drives: accidental or user-error data loss
signs of a failing helium hard drive
Clicking, whirring, or grinding sounds
Slow access or random freezing
Overheating or unexpected shutdowns
Drive not detected by the system
SMART warnings or error messages
what you should do (and NOT do)
Stop using the drive immediately to avoid further damage.
Contact a professional data recovery lab for evaluation.
Don’t use DIY tools or software - they can worsen internal damage.
Don’t open the drive - helium HDDs require a sealed cleanroom environment.
