The only problem we have is: that the calibration data seems to get rather big (200kB - 400kB?) and it _seems_ that it has to be transfered with one SCSI command. (From the windows-log they seem to be also using a single command ...). I'm not such a SCSI freak - so is it possible to devide a SCSI command into single small ones? > Abel k33p h4ck1n6 René -- René Rebe (Registered Linux user: #248718 <http://counter.li.org>) eMail: [email protected] [email protected] Homepage: http://drocklinux.dyndns.org/rene/ Anyone sending unwanted advertising e-mail to this address will be charged $25 for network traffic and computing time.
