Issue with installation from a specific USB stick

I have an old 1GB USB drive that I want to dedicate to being my Proxmox install stick (I've already labeled it as such). I tried to set it up the same way as I always have with other USB sticks:
  • dd if=/dev/zero of=/dev/sdX status=progress
  • dd if=proxmox-ve_*.iso of=/dev/sdX status=progress
  • sync
  • (remove stick)
For every other stick I have tried, this works fine (as it should since it is basically what the Wiki says to do, minus the bs=1M and plus the status=progress). For this stick, the dd completes properly, GRUB launches, but when I get into the installer boot, it fails with "no cdrom found". Choosing the Debug option from GRUB doesn't yield any extra lines of output. If I run "fdisk -l" from the command prompt after the installer fails, it shows the USB disk with an EFI partition, but this appears to be a version of fdisk that doesn't understand GPT. I have tested this stick and gotten this behavior from two different systems, an AsrockRack E3C224D2i and a Supermicro X11SSH-LN4F. I have tried multiple different BIOS options such as XHCI handoff, Safe Boot, etc. I have tried it in both USB2 and USB3 ports.

I am comparing two sticks currently. Stick A (not working) is a "Lexar Media Jumpdrive Secure 1GB". Stick B (working) is a "PNY Attache 32GB". Both are USB2.0 and use the usb-storage driver, at least at my Fedora27 desktop. I see no differences in "lsusb -v" and in usb-devices that would account for this issue, and the "fdisk -l" output post-dd is the same for both. I have checked the Lexar drive for bad blocks. I have not found a way to verify that the data written to the stick matches the ISO.

Currently, I am suspecting there is some driver issue that is causing the Lexar stick to not be seen when searching for the cdrom. I am probably wrong about that, and will accept any suggestions.
