Alternatively, the slider may have fallen out entirely and therefore be rendered effectively useless! For the record, if that happens it's possible to put a piece of matchstick or similar in the gap where the slider was and tape it in place, making the card writeable again.

Re: [Hampshire] S.D. Card stuck in read only
I recall putting an SD card in two different Ricoh readers under different Linux OS' and being baffled until I worked out the read-only tab worked in different positions in each, after which the SD card was convinced it was read only after you swapped back, so you had to switch it a second time before writing on the other reader! Some local reality distortion in which binary has more than two values??

Re: [Hampshire] S.D. Card stuck in read only
Two different adapters. Both with lock switches open. Both tested through this laptops internal reader and a USB SD adapter. Both working with spare 8gb card. Also tested with 2 machines. :/ Bryn On 18/11/11 17:06, Vic wrote: Nov 18 16:54:10 HP2 kernel: [135650.375604] sd 27:0:0:0: [sdb] Write Protect is on OK, your machine believes you' redelberately tellig it not to write to the card.
