MMC1 keeps getting set to read-only...
 

For some reason, my N800 keeps setting (or just thinking that) my MMC1 card (removable SD) to read-only. But, when I Get Info on the card, the checkbox is not checked. (And, since it is read-only, I can't even check/uncheck the checkbox).

This has happened on two cards so far with no action on my part -- it just turns out to be read-only at some point.

Has anyone ever experienced this?

Also, I have been given a few ways to try to change the card's filesystem back to read/write, but I was wondering if anyone here has the "right" way to do this.

Thanks,
Tim

I can't help, but I can commiserate. It happens to me all the time. And it seems intermittent. When the N800 claims the card is read-only, I have been able to connect to a PC via USB and write to it.

Wierd!

Re: MMC1 keeps getting set to read-only...
 

When cards go to read-only it's usually because of some physical problem with the card.

Re: MMC1 keeps getting set to read-only...
 

my SDHC 8 gig card seems to have this issue, both with the old 2007 and new 2007, both with modified kernel.....
opening and closing the little door on the front seems to change things...

Doesn't matter though, I put my (hundreds of hours of) music on via USB and use the 4 gig non-sdhc in the internal slot to save stuff....

For me, it is definetely an SDHC issue (I think).
Often, the physical switch on my SD card (the SDHC card), when switched to "read only" works for saving, and when switched to "write" does not....

who knows....

check the external switch on the actual card though.

No, the switch is fine.

And, as I said, this has happened with two cards -- both good before placing in the MMC1 (removable) slot.

But, this being said... Windows sees the card as read/write -- and has no trouble using the card.

This is a 4GB card, though... Ugh. Any other suggestions?

Because Nokia explicitly stated that 2gig cards were supported,
and made no mention, claim, or guarantee that a 4gig card would work,

and because I can save to all my cards (big, small, SDHC or not)
via terminal commands,

I have to assume this is a "File Manager" problem,
that Maemo software app. is the weak link here.

My 770 with the unofficial OS 2007 shows a similar problem:

I cannot modify the filesystem on the MMC with the filemanager anymore.
The card is OK (fscked already), and it happens to every MMC inserted into the
770. The funny thing is that all applications on the 770 can read and write the card. Only the filemanager keeps telling that it's not writable.

I guess it's time to reflash the device... :(

Interesting. Ok, makes sense.

Sorry to put a fly in the ointment -- but my card is a 1 GB RS-MMC.

Re: MMC1 keeps getting set to read-only...
 

And you have the same issue?

Does the card still work on a PC?
