Hi there, I need to make CD's out of AKAI's HD, but my only computer having SCSI ports is an old pc being only able to run linux. There are a lot of posts on the net on how to do that using toast under mac but not so much for linux users. Have anyone tried a command called "dd" to dump a SCSI disk into "burnable" image? Will it work? What should be a parameters? Regards ReverbRick

It depends on how the Akai sees the disk. If it has the same format on a CD as on the hard disk, DD will work just fine. I've dd'ed the contents off an Emax II disk and burned them to CD with cdrecord, and it worked perfectly well. You'll probably have to name the image file <something>.iso so it gets written as an ISO file, even though it's not actually in ISO9660 format. Probably something like "dd if=/dev/sda of=test.iso bs=512" should work. If not, try bs=1024 or bs=256 but I'm *almost* sure that the Akai uses 512-byte blocks on disk. Gordon

Thanks Gordon, That is exactly what I was looking for. Akai disks are the same as CD's and have 512 blocks. I'll try it up today afternoon. Regards Daniel

Gordon, It worked after a short fight caused by my lack of knowledge in linux matter. Command I used was "dd if=/dev/sda/ of =test.iso bs=512 count=1105000" I had to add "count" parameter because my disk size was bigger than it was formated at. I nicely cut my iso down to 540Mb. Thanks again Daniel

To make things easier and a little quicker , you could have done this: dd if=/dev/sda/ of =test.iso bs=1MB count=540 This will tell Linux to try and read 1MB at a time rather then 512 blocks, fewer ,larger I/O's make things go a lot quicker and the end result is the same data in the iso.

Be careful doing that if you're copying from a SCSI CDROM - some of them have got "interesting" ideas of block sizes. Gordon
