格式化dvd光盘时提示this disk is write protected

[-柚子皮-]

Not all cards have a write protect switch. I had this issue and found that it was multiple cards all of which didn't have the switch, I quickly realized that the issue was my PC not the card since the cards did work in another PC. Here's how I fixed it: open Regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrrentControlSet\Control\StroageDevicePolicies If there is a WriteProtect key (REG_DWORD) then 1 = Write Protect On 0 = Write Protect Off Set to 0 and try (may have to reboot in some cases)

This is how i solved my issue running windows vista. All other solutions did not work. The slide thing was not on lock, i could not find storagedevicepolices so yea hope this helps. 1. go to "My computer" 2. right click "SD card" your Sd card 3. select "properties" 4. Click "hardware" tab 5. under "all disk drive" heading there are a few selection, select your SD card among the options 6. click "properties" 7. under the "general" tab, click "change settings" 8. click "policies" tab 9. then click "OPTIMIZE FOR PERFORMANCE" setting this setting enables write caching in windows to improve disk performance. to disconnect this device from the computer, click the safely remove hardware icon in the taskbar notification area. 10. click ok

格式化dvd光盘？？？ 提示应该是写保护？ 不是很明白，光盘通常是只读的，除非是RW那种

[空心兜兜]

为什么要格式化光盘？

[-柚子皮-]

光盘是recordable的，但是写入时候提示满了，然后格式化提示写保护

想刻录一首音乐到光盘里面

光盘上只是写着recordable,我以为可以读写的，不知道怎么去掉写保护，还是其实光盘根本不能写

recordable？那种反复擦写的，记得以前是要50元左右一张，普通刻录盘，5元左右一张。。。

recordable，更可能是一次性的可写入盘吧；可多次写入的好像是 re-writable 的。

是 dvd±r 的还是 dvd-rw 的？前者只能写一次，满了就不能再写了，也不能格式化了的；后者应该是可以的。
