What to do right now
- Listen to the drive: clicking, beeping or grinding means stop and power it off.
- Try another cable, USB port and, for 3.5-inch drives, the power adapter.
- If it reads normally, scan it; if it shows errors, create a disk image first.
Step by step
Rule out cable and power problems
Use a short cable connected directly to the PC, try another port and make sure desktop-size drives have their own power adapter connected. Many drives that seem dead are only underpowered.
Check Disk Management
Press Win+X › Disk Management. If the drive appears with its partition, it can be scanned. If it appears as Unallocated or RAW, do not initialise or format it.
Check the drive's health
Open Disk health & tools. Many USB enclosures block SMART data, so Not enough data is common. Read errors during the pre-check matter more than a missing value.
Image first if the drive is unstable
If the drive is slow, disconnects or reports read errors, create a disk image on another drive. Imaging skips bad areas first and returns to them later, so you get the most data with the least stress.
Recover from the drive or the image
Run the Balanced scan on the drive, or on the image file if you made one, and save the results to a third disk.
Logical damage versus physical failure
Logical problems include deleted files, an accidental format, a lost partition or a file system damaged by unplugging without ejecting. The hardware is fine, so software can help, and you can scan as often as you need.
Physical failure means worn heads, damaged platters or a broken controller. Signs are clicking, a drive that spins up and down, very slow reads or repeated disconnections. Every extra hour of use can make things worse, so a recovery lab is the right choice for valuable data. Software is only appropriate when the drive still reads reliably.
When it won't work
- Clicking, grinding or a motor that does not spin needs a recovery lab, not software.
- Hardware-encrypted drives can only be read with their own unlock software and password.
- If the USB-SATA board of the enclosure failed, the drive may need to be connected another way, which can be impossible with some encrypted enclosures.
How FileFix Ultimate helps
- Shows a pre-check with read errors and device instability before a long scan starts.
- Creates bad-sector-aware disk images that skip damaged areas first and can resume later from a map file.
- Scans VHD, VHDX, E01 and raw images exactly like a drive.
- Stops a surface or recovery scan when errors pile up, instead of hammering a failing disk.
FileFix Ultimate is free, works offline and never writes to the drive you are recovering from. Check the signature before you run it.
Frequently asked questions
My external drive is not detected. Can software help?
Only if Windows can see the device in Disk Management. If it does not appear at all, check cable and power; if it still does not appear, it is a hardware problem.
Should I take the drive out of its enclosure?
Only if you are comfortable doing so and the drive is not hardware-encrypted by the enclosure. Opening the drive itself must never be done outside a lab.
Why does the health check say Not enough data?
Many USB adapters do not pass SMART data through. That does not mean the drive is healthy or unhealthy; it means the value could not be read.
