Problema di comunicazione masterizzatori IDE e SCSI

[Krywen]

ho 2 masterizzatori: un plextor CD-RW SCSI e un altro DVD+RW collegato con il cavo ide.
ora da due settimane a questa parte non funzionano: quando provo a scivere qualcosa su disco sia DVD che su CD (su entrambi i masterizzatori) non ci riesco.
a volte quasi subito mi dà un generico errore di comunicazione (preciso che fino a qualche settimana fà funzionavano poi non sò cosa ci ho fatto), altre volte arriva fino al 30-40% di scrittura prima di darmi un qualche errore.
ho provato sia nero che CDburner PRO.

pensavo di cambiare ilcavo IDE ma mi pare strano che non funzioni neanche il masterizzatore SCSI.
inoltre i dischi li leggono bene ma non reisco a scriverci. ho già aggiornato i firmware

l'errore di nero (che dice ora che ho installato una nuove versione) è:

errore driver DMA. errore CRC
F: DVDRW IDE 16x
stato di scrittura non valido
F: DVDRW IDE 16x
non è possibile eseguire fine traccia
scrittura fallita a 4x

riporto il log di nero
