What happens when you try and format them? YOu don't tell us what message you get.
I have found that some media just doesn't work with some drives, the Sony media in particular doesn't work with any drive I have tried, so I don't use it.
Try different disks, take the ones you bought back.
Hi,
I have just opened a pack of TDK 12*10*8*4* High Speed CD-RW's ("for high speed recorders") to find that none of them will format with my "INCD UDF packet writing" software.
I was previously using exactly the same CD's with the only exception being that they are "10*8*4*" (ie not 12*)
I've tried reformatting one of the old ones to check that the CD-RW drive is not broken and they format fine. Also, I've checked 3 or 4 in the new batch and they all have the same result.
I have an emachines 570 with a 2GHz Intel Celeron processor and a Samsung CD-R/RW SW-240B R400 (40* max write) and I'm using Windows XP home.
Any ideas?
Thanks
Mike
