As default ddrescue uses the kernel i/o to do the reads. If the kernel is only set up to support Spark disks, then this might be your problem.

You could try using the -d flag )direct disc access for input file) but you would then have to set the correct blocksize for the device (-b xxx).

Hope this works :)

    • ddrescue tells me the -d flag is not supported on this system. Is there a way to config the kernel to support non-solaris disks? Thanks for your help!

    • I have no idea, tbh -might be a good idea to ask in #opensolaris or similar. urm, if it was linux, then I'd say make sure the correct drivers/fs were compiled into the kernel. Are you sure the disk isn't BORKED?

Warm tip !!!
