Can I recover an external hard drive myself?

If it appears in Disk Management, stays connected and makes no unusual noise, then often yes — read-only software handles missing partitions, unreadable file systems and deleted files well. If it is clicking or dropping off, no.

Should I take the drive out of the enclosure?

Not on a WD unit. Most modern My Passport and My Book drives encrypt in hardware with the key on the USB bridge board, so a bare disk reads as unformatted even when healthy — and Windows then offers to initialise it.

Where should I install recovery software?

On a different drive than the one you are recovering, or run a portable version from a USB stick. The installer writes, and it may write into exactly the free space holding your files.

Can I recover files back onto the same drive?

No. Writing recovered files back onto the source overwrites the space still holding everything you have not retrieved yet. Always recover to a third location.

The scan is getting slower and the drive is clicking. Should I finish it?

No. Stop immediately. A change in behaviour during a scan means the hardware is deteriorating under the load, and continuing reduces what can be recovered afterwards.

When is a lab genuinely necessary?

Mechanical noise, a failed bridge board, firmware or controller faults, and hardware-encrypted WD drives whose enclosure has been discarded. In all four the drive cannot be read conventionally, so no software can begin.

External drives · recovery

Detected but unreadable is a job you might finish yourself.

If the drive appears in Disk Management and is not making noise, you are in the territory where read-only software works. If it is silent, clicking, or vanishing on and off, you are not — and the difference matters more than any tool.

Reading is free. Writing costs.

Copying off, imaging and read-only scanning cannot make the situation worse. Formatting, chkdsk, initialising, and installing recovery software onto the drive itself all can, and routinely do.

×If the drive is not detected at all, this page is not the right one — that is a hardware question, and the checks are different. This covers drives that connect but have lost data: deleted files, a vanished partition, a format, or a volume that mounts as RAW.

// three things in one case

and two of them are not the disk.

An external drive is a disk, a bridge board translating it to USB, and a power path. Two of those three are not the disk, and between them they cause a large share of the failures — which is why an undetected external so often turns out to be a healthy drive behind dead electronics.

Establishing which part failed is most of the diagnosis, and several of the checks cost nothing.

One warning first, because it is the expensive mistake: do not take the drive out of the case before it has been assessed.

// why not to shuck it

The key may be in the enclosure.

WD My Passport and My Book encrypt at the bridge. The disk holds ciphertext and the key lives on the board. Remove the drive and it reports as unformatted, at which point Windows offers to initialise it.

Seagate and Toshiba are usually simpler. Most of those enclosures do not encrypt, so a healthy disk can often be read directly. Still send the case.

If it is already out, keep the case. Do not discard the board, cable or power supply even if they look dead. On an encrypting bridge that is the difference between routine and impossible.

Test the power supply on desktop units. 3.5-inch externals use a separate mains adapter, and those fail more often than the drives they power.

// questions

Answered.

Try two cables, a rear port and another machine before assuming the worst. Bridge boards and sockets fail more often than mechanisms.

Decline. That message means the file system cannot be read, which is what a bridge fault or an encrypted disk out of its case looks like.

Not before assessment, and not at all on WD My Passport or My Book. Send the whole unit including cable and power supply.

From £300 +VAT, fixed after the free diagnostic. Bridge faults usually sit at the lower end because no clean-air work is involved.
