Hello guys! cdrecord -vvv -atip produces an error using my AD-7200A on VT6415 controller at my installation as you can see below: cdrecord -vvv -atip TOC Type: 1 = CD-ROM Device was not specified.

For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from the wodim documentation.

Device is getting UDMA 4. Testing was performed at 32bit MX Linux with kernel 6.1 at P4i945GC. Old good Pentium 4 with 1 core powering 20 PCIe lanes. 20+ years later and most PCs are stuck to 20 or 24 PCIe lanes while there are 64 or even 128 cores now plus NPUs. Something feels awfully wrong here... The same command works when cable is attached to the IDE port of ICH7: cdrecord -vvv -atip Device was not specified. Trying to find an appropriate drive...

Also please share a dmesg to identify the errors you get and the kernel in use. Output from IDE controller PCI config could be handy: sudo lspci -nnnnvvvvxxxxks 05:00.1 Guys cable detect seems broken. With a 40 conductor cable in Linux I get: ata3.00: ATAPI: Optiarc DVD RW AD-7200A, 1.09, max UDMA/66 also UDMA 4 is selected in hdparm while BIOS says UDMA 2 Finally cdrecord -vvv -atip command is not working properly with 40 conductor cable. I get wrong results but no hang was observed at all during the tests. Best regards, Ioannis
