Don't format CDR'S, you can format a CDRW but not a CDR, if you do, you have just toasted it.
I am recently having a problem formatting CDs for data storage. I put a blank CD in the drive, Vista asks me what I am going to format it for (Music, Files, etc), and Vista begins the formatting. This inevitably ends up going through the whole process with "0 seconds remaining" and it gets stuck there. In order to stop the process I have to start up task manager and the cd/dvd drive will not respond unless I reboot.
I am running Vista Home premium on an AMD athlon 64x2 4600+
with 4 gb of ram and tons of empty hard drive space.
