Use the Panasonic SD formatting tool and reformat the SD stick. You can find the tool on the internet. Hopefully you don't have data on the stick thatt you need. Have you looked for drivers updates for your SD reader?

Checked out the Panasonic formatter as suggested but SanDisk 8Gb card doesn't appear to be supported. I tried the SanDisk formatter but it says it can't format the card because the card is write-protected. I got the same answer when I tried to format the card using device manager. It seems that a card needs to be already un write-protected before you can format it!
Checked the HP site for driver updates but there don't seem to be any for the card reader.
Thanks though - and if you have any other thoughts ..........

Just thought I'd give you the good news. I had a reply from SanDisk this morning. This is what they told me to do
"If the lock switch is not on lock:
1. Slide the switch up and down. Repeat this 3 times.
2. Let it stay on the Lock position for 30 seconds.
3. Slide the switch up to unlock the card.
4. Try to transfer files into the device."
I have no idea what this is all about (why three times and why 30 seconds!) - it seems crazy that it's so simple - but it works! The card is no longer write-protected and I can save files to it.
I hope this will help someone else - I can't be the only one to have had this problem ..... can I????
Thanks for taking an interest.

I have no idea why this works. Considering SD cards don't have a power source and should have have a "memory" of anything when not plugged into a device I have no answer. This does work. I just did it and then formatted the SD card and was able to write files to it. This is the craziest solution to a problem that I have heard of in my 23 years of troubleshooting issues with computers. Thank you.

Most Pavilions have an SD card slot that deteriorates over time with frequent use until the contacts that 'detect' the write protect status get dirty or deformed. The result is either failure to detect the card when inserted or a false detection of write protect status.
The solution ranges from simple blowing out the slot to dislodge any dirt to physical repositioning of the fatigued contacts so that the unlocked status is again detectable.
Although HP Pavilions are notorious for this problem, it also applies to many other devices. Perhaps the SD card slot comes from a common supplier - I don't know, but it's 99.9% likely that the slot contacts are at fault when you get a false write protect status no matter what SD card is inserted.
