Subject: Disk errors when copying


When copy between disks (ad10 ->ad8), I get errors:

ad10: WARNING - READ_DMA48 UDMA ICRC error (retrying request)
LBA=435128800
ad10: FAILURE - READ_DMA48 status=51<READY,DSC,ERROR>
error=10<NID_NOT_FOUND> LBA=435128800
g_vfs_done():ad10s2g[READ(offset=175562145792, length=131072)]error = 5

I don't get these errors just reading the data from ad10.  Is this
some kind of system error rather than a bad disk?  Is it a known problem?


Yes it is a known problem.  It does not happen with most combinations
of drives and controllers.  You need to exhaustively document the
motherboard/controller/hard disk and put it into a PR and file it
so that the developer can add your combo into his database.  The more
of these that are documented the quicker that a coorelation is going
to show up and get fixed.

I wish I'd known that before I trashed my disc and spent a couple of weeks
and hundreds of bucks building a new system.
