I have this old 4x CD-RW here (TDK) which I am unable to erase to its full capacity anymore, or actually I don’t know whether it gets erased to its maximum…
I’m using ImgBurn 18.104.22.168 for all burning and authoring, and the status window at the right side of the main window says the following about this CD-RW:
_NEC DVD_RW ND-3500AG 2.1B (ATA) Current Profile: CD-RW Disc Information: Status: Empty Erasable: Yes Free Sectors: 359.847 Free Space: 736.966.656 bytes Free Time: 79:59:72 (MM:SS:FF) Supported Write Speeds: 4x ATIP Information: Start Time of LeadIn (MID): 97m10s0f Last Possible Start Time of LeadOut: 79m59s74f
Now here it says the disc has a max capacity of ~703MB.
But the last part of the log is puzzling:
Current Format Capacity: Sectors: 295.232 Size: 604.635.136 bytes Time: 65:38:32 (MM:SS:FF) Preferred Format Capacity: Sectors: 295.232 Size: 604.635.136 bytes Time: 65:38:32 (MM:SS:FF) Maximum Format Capacity: Sectors: 295.232 Size: 604.635.136 bytes Time: 65:38:32 (MM:SS:FF)
That’s only ~577MB! Is this because the disc has a bad sector at 295.233 (and following)? Or maybe didn’t ImgBurn erase the disc correctly?
I’m able to burn bigger images to the CD-RW than the format capacity tells me, but when verifying I get a weird error message… verify failed, but the controller didn’t notice an error or something like that. Sorry, got no log at the moment it’s one of those ATAPI error windows with a lot of opcode in it.
So is this what happens when a CD-RW goes bad: I can still use some of its capacity?
