Ah! Yes, I was paying attention when you mentioned this in an older thread. I also checked online reviews to confirm that they were still making good devices before I ordered this one. > > Running 'readcd f=cd_test.out -noerror' gives me an ever increasing > > number of errors, on each sector (currently up to sector 6 and still > > going strong): > > > > # readcd f=cd_test.out -noerror > > No target specified, trying to find one... > > Using dev=2,0,0. > > Read speed: 22160 kB/s (CD 125x, DVD 16x, BD 4x). > > Write speed: 22160 kB/s (CD 125x, DVD 16x, BD 4x). > > Capacity: 250000 Blocks = 500000 kBytes = 488 MBytes = 512 prMB > > Sectorsize: 2048 Bytes > > Copy from SCSI (2,0,0) disk to file 'cd_test.out' > > end: 250000 > > readcd: Input/output error. read_g1: scsi sendcmd: no error > > CDB: 28 00 00 00 00 00 00 00 40 00 > > status: 0x2 (CHECK CONDITION) > > Sense Bytes: F0 00 03 00 00 00 00 0E 00 00 00 00 11 05 00 00 > > Sense Key: 0x3 Medium Error, Segment 0 > > Sense Code: 0x11 Qual 0x05 (l-ec uncorrectable error) Fru 0x0 > > Sense flags: Blk 0 (valid) > > cmd finished after 7.030s timeout 40s > > This is an error at the layer above the audio sector.

Better verbatim media identify as > Verbatim (DVDs and BluRays may use IDs from the business group). Thanks again for your help (and software) Jörg.

I will be using my media and burner when I meet him next time, to avoid disappointment. ;-) -- Regards, Mick
