Known on this model. Barracuda 7200.11 drives of this era had a well-known firmware fault: the drive suddenly shows as 0 GB or isn’t detected at all (the “BSY” fault). The data is usually intact and recoverable through the drive’s service mode.

The clean-air cabinet used to open hard drives

What is it doing?

The noise or behaviour tells us a lot about what has failed. Tell us when you book.

What it is doing	What it usually means
Clicking or ticking	Heads failing to read. Stop powering it on; each start can scratch the platters.
Buzzing, no spin	Stuck heads or a seized motor. Needs the clean-air cabinet.
Not detected, no noise	Electronics board, firmware or power. Often the data is untouched.
Slow, freezing, bad sectors	Weak heads or damaged surface. Copy it now, before it gets worse.
Deleted, formatted or a RAW partition	Logical recovery from the healthy drive, from £99 + VAT.

How we recover it

Free first consultation: we tell you what has failed and the price before any recovery work starts.
The drive is copied sector by sector first. Nothing is ever written to your original drive.
Clicking, buzzing and stuck drives are opened in our clean-air cabinet; donor parts are matched by model number, firmware and production details.
Your files come back on a new external drive, or copied to your new computer.
Everything is kept confidential. Our working copies are deleted once you confirm you have everything.

Before you send it

Don’t keep switching it on to see if it works: every start can make the damage worse.
Don’t open it, tap it or put it in the freezer.
Don’t run CHKDSK, Disk Utility First Aid or recovery software on a failing drive.
Don’t format it when Windows or the NAS asks you to.
