Old Transcend StoreJet External Drive Has No Power or Activity
Asked by

I'm trying to access an old Transcend StoreJet 640 GB external hard drive, model 380440-0124, that may be more than ten years old. It has been unused for several years and contains important family photos.
When I connect it to a Windows 11 laptop, it shows no LED activity, vibration, fan noise, or other signs of power. Windows Device Manager does not detect it either. I tested both a USB 3.0 Micro-B cable and a USB 2.0 Micro-B cable, and the same cables work with another external SSD. I also tried holding the drive's front button, but nothing happened.
The laptop recognizes my phone normally, so the USB ports appear to be working. A recovery application detected the laptop's internal drive but not the Transcend drive. I would prefer to try safe hardware troubleshooting before using a professional recovery service, especially since I'll be traveling soon. Is it possible to remove the drive from its enclosure and test it with another enclosure or a direct SATA connection, and what should I avoid doing to protect the photos?

The USB-to-SATA bridge or the enclosure’s power circuitry may have failed even if the internal hard drive is still healthy. You can carefully open the enclosure, remove the drive, and check whether it uses a standard SATA data and power connection. If it does, test it with a known-good SATA-to-USB adapter, another enclosure, or a desktop PC’s SATA connections. Don’t initialize, format, or run repair tools if Windows detects the disk but asks you to set it up—those actions could make recovery harder.

Since the drive shows absolutely no light, sound, or vibration, the problem could be the enclosure, its power board, the USB bridge, or the drive’s own controller. Replacing the cable alone probably won’t help if multiple known-good cables have already been tested. The Transcend model is reported to use a standard SATA-based internal drive, so bypassing the enclosure is a reasonable diagnostic step. If the drive still has no activity when connected directly, stop experimenting and use a reputable data-recovery service rather than repeatedly powering it on.

A recovery program cannot detect a disk that is not receiving power or appearing at the hardware level. Software troubleshooting and driver updates won’t fix that kind of failure. First isolate the enclosure from the disk; if the disk is detected, immediately copy or image the important data to another drive. If it is not detected or makes unusual clicking sounds, avoid opening the drive itself and seek professional recovery assistance.

MellowCedar47: That makes sense. I’ll check the enclosure first and avoid writing anything to the drive.
