Sounds to me like a job for dd, or more specifically, ddrescue. ddrescue is featured on the System Rescue CD (http://www.sysresccd.org/SystemRescueCd_Homepage). With ddrescue's logs and many ways of writing, you can be assured of the maximum possible likelihood of getting the job done, and finding out if either drive has problems that should concern you. If you want a quick way of cloning the drive that isn't particularly error prone, this is it, especially if your 250 is fairly full so that file by file copy wouldn't save you much. If both drives are in good shape so there are no misreads or miswrites, I'd imagine the clone will take about an hour, unattended. If there are disk problems it will take longer, but file by file might have missed that fact and written bad data. > My fstab contains blkids to identify the root, swap, and home > partitions.

After cloning the 250 onto the 300, the 300 will boot just like the 250, always assuming your last step before doing the clone is to get rid of the 300's entry in fstab. Labels and blkids on the 300 will be identical to the 250's after cloning. > > Also is there a simple method to resize the future home partition and > move the root partition so that I don't end up with unallocated space > on the drive? Now you're getting a little complicated. What I always do in this situation is just make an additional partition to consume that last bit of drive space, and usually find a use as a scratchpad area for that partition. Or, if you really want to make /home bigger, you can take the biggest subdirectory in /home significantly smaller than the new partition, rsync its contents to the new partition after mounting it, back them up somewhere else, remove them leaving only the empty directory on the original, and mount the new partition as that directory. If you want to expand a partition to include the unallocated space, I think you have to use whatever partition butts up against the unallocated space to make bigger. If there's a tool to enlarge a different partition and move the others to compensate, I"m not aware of it.
