His WD My Passport is operational (power and life) but shows no evidence of being present. The drive "has power to it" and he can "hear the disk spinning inside", however it is "not found on windows, mac or android". Further complicating this issue, he mentions: "The disk has possibly been formatted also". A drive that is spinning but detected by none of these systems has a fault somewhere between the working motor and the handshake with the host. The possible format is a separate, second question on top of this, so the assessment has to determine which problem, or both, is actually in play.
| Media | WD My Passport Ultra portable external drive: powered and spinning but undetected by Windows, Mac and Android hosts; possibly formatted at some unknown time according to the owner |
| Reported situation | Drive receiving power, audible spinning · not appearing on any of three different host platforms · possibility the drive was formatted at some unknown time · data recovery services desired · uncertainty whether the problem is an access issue, a format issue, or both |
| Fault class | An enumeration error on a spinning drive: a bridge, connector or firmware problem preventing detection, potentially layered with a format event affecting the filesystem behind it. Additionally, due to the My Passport's hardware encryption, its encryption status also has to be considered when determining how to proceed. |
| Equipment used | Current draw profiled on a bench supply, then the drive taken out of its case and connected directly to native SATA to isolate a bridge fault from a drive fault · bridge board and connector reviewed under a stereo microscope, the original bridge kept for its hardware encryption role · drive evaluated on PC-3000 UDMA for firmware and enumeration faults · imaged on DeepSpar Disk Imager once it identifies, file system structures parsed in R-Studio for any format event, prior structures rebuilt or the data area carved · extracted files verified against hashes |
Spinning is a genuine positive, but a precisely limited one. That a drive can power up and spin means the motor is functional and the mechanism is receiving power (this eliminates total power failure and many types of mechanical seizure). But spinning only gets the drive to the start line; it is only when the drive completes a handshake with the host that it is detected, and this drive is unable to do so. The fact the motor works tells us the problem is somewhere else.
The same drive failing on three different host types (Windows, Mac and Android) indicates the problem is within the drive and not one of the hosts. Eliminating an OS, driver or platform issue leaves only issues with the drive's own ability to enumerate, usually a failed or faulty USB bridge board on a portable unit, a bad connector or bad firmware.
An external My Passport portable adds a specific concern to the analysis. Portables with a My Passport enclosure encrypt in hardware on the bridge board as standard; thus, the drive itself contains ciphertext. Therefore, the bridge and its encryption function must be preserved through the recovery, because transplanting the bare drive into a generic caddy would present unreadable encrypted data. This is why the original electronics, including the bridge, are retained, and why bridge-based faults in these drives require careful diagnosis instead of simply replacing components.
Determining if the drive has been formatted is a completely separate issue from the detection fault. Once the drive is accessible, we can check whether it was formatted. "Possibly formatted" describes the filesystem, not the detection fault, and it may or may not have happened. If the drive had been formatted, the previous data will typically remain beneath the newly created empty structures, recoverable by rebuilding them or carving the data area. Only after the enumeration fault has been corrected and the drive can be read does the format question matter. First access, then the format question.
Both faults are analysed in order, and honestly. Before we can determine if a format occurred, we first need to repair or bypass the bridge, or address a firmware fault, so that the drive can be imaged. Second, on the image, we assess whether a format did occur and determine which method of recovery will best recover your data. Both are established through layer-by-layer diagnostics, not assumed, so at each stage a prognosis is stated before proceeding further.
A reasonable data outlook across the likely scenarios. While a bridge or connector failure would cut off access to the disk (but not damage the platters), a format will leave data in place. So, assuming the physical mechanism is intact, as the continued spinning suggests, a detection fault or a format are both problems that recover well. The honest exception would be a firmware or mechanical fault found during the assessment; these are scoped before proceeding with recovery.
Using a bench power supply, we profiled current draw, and we removed the drive from its enclosure and connected it to native SATA to separate a bridge fault from a drive fault. We used a stereo microscope to examine the bridge board and connector and, since one function of the original bridge board is to encrypt the drive's contents, we retained it. We then assessed the drive on PC-3000 UDMA for firmware and enumeration faults. Once the drive identified, we imaged it using the DeepSpar Disk Imager. Finally, we parsed the filesystem in R-Studio for evidence of a format event, rebuilt prior structures where applicable or carved the data area, and hash-verified the extracted data.
Detection restored at the bridge, a copy (image) made of the disk, and any format issue resolved from this image. The assessment is free and the quote is one single fixed amount plus VAT. Where we have to open up the disk, 50% of the fixed quote is payable upfront, and the remainder only if we recover your data. The decode: spinning got you to the start, but not over the finish line. The problem lies in the disk's path to being detected, most likely the bridge. Fix the bridge first, then any format becomes a second, recoverable layer behind it.
Stop reconnecting it to different devices to see if it shows up. A spinning drive that isn't detected on multiple systems has a fault in its own detection path, not a problem with your computer, and you will never get past it by trying to connect it repeatedly. With a WD My Passport, do not allow anyone to remove the internal hard drive from its case and put it in a generic external caddy. These are encrypted at the enclosure board level, so the original electronics must be preserved or the data reads as noise. Any possible formatting of the disk is a separate recoverable layer, to be sorted out only after the disk can be detected again.
