This is my first post. I read through the post labeled :.....D:\ is not accessible. Incorrect function. and did everything people suggested there but I am still having the same problem except mine is a little different. I don't know if it is a hardware or software or driver or what the problem is..... My external and internal burner have error G (burner in the computer) & F (external burner) :\ is not accessible. Incorrect function. My other internal player works though. It plays music but I can't view pictures. I have an external burner hooked up thru a USB port and I have a cd/dvd burner on my computer. Both drives are giving my the same error message...I don't know what to do. I have tried different usb ports...plugged the external burner into 4 different ones. I tried buying a different usb cord for the burner...nope I have tried different cds and dvds..different brands and types. I have tried: support.....microsoft.com...fixit website which helped a lot. I couldn't even play music until I used that website. Now I can at least play music I just can't burn anything. (btw. that website is awesome for a lot of things). I have tried unistalling Roxio because someone said that might be my problem. (Nope) I have tried updating my drivers. I have tried going to device manager and seeing if there is any exclamation points but they say everything is working properly......lol!! I don't know what else to do or what the problem could be because it is happening on both and internal and external burner. I thought I might have to replace my internal burner but now I don't think that is the problem at all. BTW I have a Sony Vaio PCV-2222 with a Toshiba DVD-Rom SD R5002 and a Samsung CD-Rom SC-140C. And I have been to all three of their websites looking for driver updates or firmware or something to help and have downloaded everything they had and nothing has fixed my problem. I am running XP Pro. I am completely out of ideas...... Please help me. I really don't have the money to spend and get my computer fixed and I don't think that would fix it because it is having trouble with the external one too. Any help would be sooooo appreciated!! Thank you in advance!!
