Is it safe to dd two drives, if you want to simply transfer data?

[Carruth, Rusty]

I'm late to the party, but if the idea is to take the 'new' drive (the dd destination) and install it in the computer that had the dd source drive - then all this bogus Windows registration garbge should be a nonissue.  Of course, if the idea is to take the drive to a different PC - well, yes, issues will arise.

And, for the record, I use DD a lot when duplicating drives.  As long as the target is as big as (LBA count!!!!!!!) the source, there should be no issues.

IF, however, you have read issues on your source drive, then DO NOT USE DD!!! Use DDRESCUE instead...

well, you might need to set block size to make the transfer optimal. Also, dd the entire drive to an image on the destination drive (assuming the destination is larger). this will preserve the partition table and filesystem attributes.

Hey everyone,

So my gf's wip computer seems like it has a bad drive. (100% usage when not doing anything, and Windows can't see anything wrong with it.) My gf's newphie's old computer still has a good drive. I'm not sure if it's larger or smaller then the bad one, but I was planning on using dd on my main machine to simply copy all the data into the newer drive from the bad one, plus also I don't have Win8 cd key laying around. (gf wants to play games on it primarily)
Is there anything I need to watch out for when doing this? or should I be using another tool for the job?
Thanks,
Andrew
