On a subtler note:

Modern SSD HDD memory as well as a lot of memory sticks are computer systems in their own write (sic). They contain back-up blocks. When the regular system checks detect a memory cell looking over-worked/aging it swaps out & restores the data for that block.

For a high stakes game it would not be difficult to have its program do things. Getting that HDD into the system at the correct location might prove more troublesome. Though I would expect regular maintenance would dictate system swap-outs. NRAM (the industry std) has an MTBF of maybe 5 years.

And then there are Gamma particles............

It's a vulnerability.
