Another odd minor thing

My Amazon Fire tablet suddenly alleged my SD card was read-only. I copied a document to it, and Open Office opened it in read-only mode. This is odd because I just used it to copy 600+ images to my laptop, though originally they were on the laptop and I used the card to copy them - faster than Bluetooth (copying the images to the card and copying them to the laptop was quicker than trying to find which 4 files I hadn't copied for some reason - the card had 659, the laptop 655, when they're supposed to have the exact same files...they do now!). ATM I'm running chkdsk on it c/o a USB adaptor stick; nothing reported wrong so far. 38% checked and still running as of the time of posting this.

This doesn't really matter, as it works for its intended purpose: to backup my files and/or transfer them to and from the laptop. I'm just wondering why the tablet made this allegation. The card's quite new, so it's not an end-of-life thing. Surely if it's read-only it won't allow writing files to it, which it does. Hence my lack of concern. It's just odd.

Then again, this is me we're talking about.

This past year, I have had 3 different brands of USB memory stick become Read Only. "It's to protect the data" said 2 manufacturers.

Re: Another odd minor thing

Is this something to do with the flash memory age and total write figures??

each cell with have a maximum read write and rewrite cycles it would make sense to make data read only if the cells it was written to were nearing their end date as it were

Check if the switch on the SD card hasn't flipped
