When a hard drive fails, the real question isn’t how to repair the drive — it’s how to get your data off a drive that has already stopped working. That’s what we’ve been doing at Gillware since 2004. Our engineers recover data from clicking drives, dropped drives, dead PCBs, corrupted firmware, fire and water damage, and scratched platters in our ISO 5 Class 100 cleanroom in Madison, Wisconsin. Every case starts with a free evaluation and a firm flat-rate quote. If we don’t recover your data, you don’t pay.

What “Hard Drive Repair” Actually Means
When most people search for hard drive repair, they’re not trying to keep using a broken drive — they’re trying to get the files off it. The distinction matters. A failed hard drive almost never returns to reliable everyday use, even when worked on by the manufacturer. What can be done is a controlled, temporary repair inside a cleanroom: replace the failed component just long enough to image the platters and pull the data off safely. Once we have your data, the drive is retired. The deliverable isn’t a working drive — it’s your files, returned on new media.
If your drive is making unusual noises, won’t mount, or stopped showing up entirely, the safest thing you can do is power it down and have it evaluated. Continuing to run a failing drive in the hope that it comes back is the single most common way a recoverable case turns into an unrecoverable one.
Common Hard Drive Failures We Recover
Most of the drives we see fall into one of a handful of failure patterns. Each has a different repair path inside the cleanroom, and most have a dedicated page on this site with deeper detail.
Clicking, beeping, or grinding drives
Repetitive clicking, beeping, or grinding almost always means the read/write heads have failed or the drive is struggling to find its service area. Continuing to power the drive on causes the failing heads to scrape the platters and destroy data. Our engineers replace the head stack inside the cleanroom using a matched donor drive from our parts library. More on read/write head failures →
Drive won’t spin up
A drive that’s completely silent when powered on usually has a failed PCB, a seized spindle motor, or a stiction problem keeping the heads stuck to the platters. PCB swaps require careful work, because modern drives store unique calibration data on the board itself — a generic donor board will not work. More on hard drive failure modes →
Drive not showing up
A drive that powers on and spins normally but isn’t detected by the computer usually has a firmware problem, a corrupted service area, or a damaged head causing read errors during initialization. These cases are often recoverable, but they require professional tools to access the drive’s firmware partition. More on drives that don’t show up →
Dropped or impact-damaged drives
A dropped drive almost always means head damage, even if it appears to still work briefly afterward. The longer it runs after the drop, the more damage accumulates on the platters. Power it down immediately and have it evaluated before any further data is overwritten.
Fire and water damage
Fire and water damage look catastrophic, but the platters themselves are usually salvageable if the drive is handled properly afterward. Don’t try to dry a water-damaged drive yourself — deposits left on the platters during home drying can make recovery impossible. We’ve returned data from drives pulled out of house fires, floods, and storm damage many times.
Scratched platters
Severe platter damage used to be a death sentence for a drive. Our in-house platter burnishing process now lets us recover data from many drives with surface damage that would have been written off a decade ago. Not every scratched drive is recoverable, but more are than most labs will tell you. How platter burnishing works →
Deleted files, formatted partitions, and logical failures
Not every failed drive is physically broken. Accidental deletion, reformatting, and file system corruption are common, and the data is often still present on the platters even when the operating system can no longer see it. Our in-house software handles every major file system, including NTFS, exFAT, APFS, HFS+, ext2/3/4, XFS, Btrfs, ZFS, ReFS, ReiserFS, and VMFS.
How a Gillware Recovery Works
- Submit your case. Fill out a short form online or call our client advisors. We’ll send a prepaid shipping label.
- Free evaluation. When your drive arrives, our engineers diagnose the failure and determine exactly what work is needed. This costs you nothing.
- Firm, flat-rate quote. You receive a single quoted price for the full recovery — no hourly billing, no surprise fees, no escalating estimates as the work progresses.
- You decide. Approve the quote and we begin the recovery work. Decline it and we return your drive at no charge.
- Recovery and return. We image the drive in our cleanroom, extract your data, and return it on new media. If we can’t recover the data that matters to you, you don’t pay for the recovery work.

What Makes Gillware Different
ISO 5 Class 100 cleanroom. Opening a hard drive outside a certified cleanroom contaminates the platters within seconds. Our cleanroom workstations meet ISO 5 standards — the same class used for sensitive electronics manufacturing.
More than two decades of recoveries. Gillware has recovered data from over 100,000 failed hard drives since 2004. Every major drive manufacturer, every common failure mode, and most of the uncommon ones have come through our lab.
Flat-rate, transparent pricing. You get a single quoted price up front, not a vague range that grows once the drive is open. See our pricing approach.
No data, no charge. If we can’t recover the data that matters to you, you don’t pay for the recovery work. On a standard single-drive case, the risk is ours, not yours.
Trusted by manufacturers and IT providers. Gillware is the only data recovery company listed on Dell’s website, and more than 2,000 managed service providers and computer repair shops refer their clients to us when they need data recovered. VMware refers customers to us for recoveries in virtual enterprise environments.
Wisconsin lab, U.S.-based engineers. Your drive doesn’t leave the country. All recovery work is performed at our headquarters at 1802 Wright Street in Madison, Wisconsin.
Brands We Recover
Our engineers work on every major hard drive manufacturer and most of the discontinued ones. Common requests include Seagate, Western Digital (including WD-owned HGST and Hitachi drives), Toshiba, Samsung, and Hitachi. If your drive isn’t from one of those, send it in anyway — the failure modes are similar across manufacturers, and our donor parts library covers nearly every model produced in the last 20 years.
What Not to Do With a Failed Hard Drive
A few things to avoid when a drive has failed, in rough order of how often they cause permanent data loss:
- Don’t keep powering it on. Repeatedly cycling a failing drive is the most common way a recoverable case turns unrecoverable. If the drive is making unusual noises or behaving abnormally, power it down and leave it down.
- Don’t put it in the freezer. The freezer myth circulates online every few years. It doesn’t work, condensation damages the platters during thaw, and it makes professional recovery harder afterward.
- Don’t run recovery software on a physically failed drive. Recovery software is built for logical failures — deleted files, corrupted partitions. On a physically failed drive, the additional read attempts cause further damage.
- Don’t open the drive. Opening a hard drive in normal room air contaminates the platters in seconds. It’s the fastest way to make recovery impossible.
- Don’t swap the PCB with a board from an identical drive. The “identical” board has different calibration data, and the swap can cause additional firmware damage.

Start Your Hard Drive Recovery
If you have a failed hard drive and the data on it matters, the next step is a free evaluation. Send the drive in and we’ll diagnose the failure, give you a firm flat-rate quote, and recover the data once you give us the go-ahead. If we can’t recover what you need, you don’t pay.
