How do I format an HP-48GX FRAM Card?

[rprosperi]

Personally, I would have a trusted the statement "I checked the switch, it's OK".... LOL

There is no built-in method for formatting RAM cards as none was needed; remove the battery and *POOF*, it's formatted. There was no FRAM at the time, so no provision was made to do this by HP.

When several guys have have introduced FRAM cards over the years, this very topic was often raised, with potential buyers asking "how would I clear the card, since there is no Format?" and the seller (not necessarily your seller) replying "It's not needed, PINIT or just writing a variable should be all you need", which is likely true for a new, properly functioning card. Nevertheless, I too bought one but have been lucky and had no issues with it.

My suggestion is to create a new thread (or rename the initial post of this one) to something like "How do I format an HP-48GX FRAM Card?" to get readers' attention that it's a FRAM-related issue, and that may attract more eyes from folks that may have dealt with this issue.
