Use something like an Arduino or Raspberry Pi Pico to dump the EEPROM.
From there you can recover the HDD key and create a new hard drive without modding.
But as someone else already said, best to have a modchip installed, especially since you have a 1.6 console. No hardmod TSOP flashing.
I do not recommend buying nor installing an Aladdin XT chip, since most times you cannot flash the memory chip due to the manufacturers using the wrong chip (they're different chips that are resurfaced and relabeled as genuine). If you seriously want to gamble and go down this route, consider getting a programmer / flasher like the XGecu T48 or XGecu T56 (both of which are more expensive than just getting an OpenXenium).
