Windows 7 - Not able to burn CD's/DVD's

OK, the iso burn worked fine...

Downloaded the file and imgburn, opened imgburn and started the burn, it went on its business for a minute, then came up with an error saying that the disc tray couldn't be closed and it popped open the disc tray, which I pushed back in and imgburn continued the burn process successfully.

Opened the tray and pushed it back close and the file is on the disc.

Deleted the files on the disc and redid the process and it burned the same again, same message about the tray not being closed though.

BUT ... now I've got another development...

I thought I would try and burn a music file again, this time using wmp.

Opened up wmp picked a 3mb song to burn, dragged it to the burn pane and inserted a blank cd-rw disc ....... off it went and burnt the song fine!

Wouldn't do this last night. But when I ejected the disc and put it back in and tried to burn another song onto the disc wmp said the disc was full.

I went to mycomputer and looked at the cd drive and opened the disc up and the song file which was originally 3mb was only showing as being 22kb in size on the disc ... and yet played fine being about 3 mins in length!?

Tried another song of about 4mb in size this time, and same again, successful burn but when disc is reinserted it is showing as being full and the file only being 30kb in size .. and I cannot burn to it again!?

Then I decided to try a spreadsheet of about 50kb in size again.

Inserted a blank cd-rw disc, dragged a file to the drive and clicked burn ... tadaaa, it burnt the file ... but yet when I reinsert the disc the disc is apparently full and I cannot burn anything else to the disc and the 50kb file is showing as being 600kb in size!?!

So - now I am even more confused, any advice on the above developments?

Sounds like a bad drive.

That looks like a good drive, for a great price.

Yeah getting that impression - somethings not right with the drive.

Don't think that one you gave the link to would fit into a laptop!

Sorry about that.

You could buy an external one for less than a laptop drive.

That one looks good to me.
