📎 AI Summary:
The thread discusses an issue where a user successfully uses a USB3 external drive with Macrium Reflect during normal operation, but the USB3 drive is not recognized when booting from a Macrium rescue disk after installing a PCIe USB3 card. The original poster asks if this is a common problem or limitation of Macrium, particularly regarding creating rescue media that supports USB3 devices. A responder suggests that the likely cause is the rescue disk lacking appropriate drivers for the PCIe USB3 card, which might explain the recognition issue during boot. Overall, the conversation centers on troubleshooting USB3 device recognition in rescue environments and suggests driver support as the probable cause.

I have got v7.2 installed on my machine. All updates for win 7 are installed. Macrium reflect has performed beautifully up until now...
Knowing that my machine is getting a little long in the tooth relative to USB performance, I installed a PCIe USB3 card from StarTech. After installation was complete, I checked the function with a seagate USB3 external backup drive using a large number of photographs. Device manager shows the USB3 hub and drivers installed. The backup ran smoothly at about 70MB/sec. Next, I started up Macrium Reflect on the C: drive and checked for the external drive and it showed to be ready for action. I then proceeded to make a new bootable rescue media DVD. Where the trouble starts is when the machine is booted up with the rescue disc. The machine will not recognize the USB3 drive. I have tried pointing it the the driver location, but to no avail. Is this common? Is Macrium Reflect not able to make a rescue disc that will recognize the USB3 drive? The function of the USB2 ports have not been affected and they work fine.

Someone's help would be appreciated.

I don't use Macrium, but my guess would be the rescue disk doesn't have drivers to support the PCIe card.
