Swap 32gb Cf For Microdrive, Easy Way to Do This... Options

[ArchiMark]

Decided to take the plunge and got a new 32GB A-Data CF Card today....



Want to do this swap the right way and hopefully easy way....

I assume that I can 'clone' my current Debian EABI setup on my existing 6GB microdrive over to the new 32GB CF card, right?

Would this be the right way to do it?

1) Format new 32GB card and make 2 partitions; ext3 (/dev/hdc1 /mnt/cf) and a small swap (512MB on /dev/hdc2 /mnt/cf2).

2) Copy over current microdrive debian contents on hda2 over to new ext3 partition on 32GB CF card by doing:

CODE

#dd if=/dev/hda2 of=/dev/cf

* Note: hda1 on my existing microdrive is my swap partition.

So, is this correct way???

Thanks!

Mark

no, you definitely don't want to use "dd" to copy a file system between different types of media unless you guarantee the number of blocks in the partition is the same or larger on the target.

anyway, "cat" is faster - it uses more buffering!

the best way to copy a filesys is like this:

cd /mnt/partition1
tar cf - | (cd /mnt/partition2 ; tar xf - )

tar will copy all files and devices, preserve the datestamps and protections etc.

if you were l33t, you could probably also do it with cpio but I'm too lazy to look it up.

so, just partition the CF appropriately. oh, do NOT use ext3, the journalling will kill the card faster.

Thanks for your help with this, speculatrix!!

Will report back after I try this out...
