We're currently running one machine under kernel 2.2.5 (SuSE 6.1). We're getting byte differences between the original data (on HD) and the CD data. HW: Pentium class machine (1/2 yr old), AIC-7890/1 Ultra2-LVD, Teac 55S recorder at speed 4. Kernel 2.2.5, aic7xxx driver 5.1.13/3.2.4 mkisofs 1.12b5 cdrecord 1.8a22 the mkisofs image is OK, the differences come from the path of the data to the CD. I suspected the iso9660 fs layer first, but reading back the whole image from the CD produces a different image file :( data corruption groups into 4-bytes clusters mostly, but there are also longer blocks which differ (the 4-clusters are interleaved by 4 bytes which don't differ) Any idea for fixing ?
