The new disk will appear unclean when copied from a live fs and may in fact have an odd instance of a file which has not yet been physically updated. And it just takes too long since you copy empty space as well as real data. Instead slice, partition the new disk and create newfs on the new partitions. And then pipe dump (using the snapshot option) through to restore for each fs on the disks. I have (successfully) used this approach extensively for cloning systems.

A good tool to use is Segate's Seatools (http://www.seagate.com/support/seatools/index.html).

You might even try swapping your drive cable. Other than that it looks like your drive is failing. You do have backups don't you?

Disk error messages (ad0: HARD READ ERROR blk# xxxxxx)
Hi there, On my screen, there were messages like the followings comeing up. I have to reboot mutiple times to get it boot up normally. Does this mean I have to replace the disk which is a relatively new disk (1-2 years)? Any simple way to fix it and to avoid the time consuming task? ad0: 39205MB [79656/16/63] at ata0-master WDMA2 ad0: HARD READ ERROR blk# 131199 ad0: HARD READ ERROR blk# 131199 status=59 error=40 ad0: DMA problem fallback to PIO mode ad0: HARD READ ERROR blk# 11272319 status=59 error=40 ad0: HARD READ ERROR blk# 11272319 status=59 error=40 ad0: HARD READ ERROR blk# 11272319 status=59 error=40 ad0: HARD READ ERROR blk# 131199 status=59 error=40 ad0: HARD READ ERROR blk# 3473535 status=59 error=40 ad0: HARD READ ERROR blk# 9240703 status=59 error=40 ad0: HARD READ ERROR blk# 17367167 status=59 error=40 ad0: HARD READ ERROR blk# 17760383 status=59 error=40 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
