Since I may only get one shot, and since I've never formatted
a USB hard drive, nor ever even mounted one, how does this procedure
look for my 149GB NTFS disk?
Note:
Recuva says the cluster size = 4096 file record size = 1024.
0. {should I boot off a Centos CD or should I use my normal OS?}
1. Connect the new =150GB hard drive to the Centos 6 laptop
Note: Presumably that will be on /dev/sda0 (right?)
2. Format the new hard drive with fdisk (is this step needed?)
Note: What fdisk command is recommended?
3. Connect the old 150GB compromised USB NTFS disk to Centos 6
5. Copy data, verbatim, from the old disk to the new disk with dd
Key questions:
Q0. Should I boot to my normal Centos 6 OS?
Q1: Should I format the new USB hard disk with Fdisk?
Q2: What dd command should I use?
Googling, and looking at fdisk options, should I run?
# fdisk /dev/sdb
# fdisk -l /dev/sdb
Googling, I find multiple dd examples {which block size should I use?}
# dd if=/dev/sda of=/dev/sdb
# dd if=/dev/sda of=/dev/sdb bs=1M
# dd if=/dev/sda of=mbrbackup bs=512 count=1; dd if=mbrbackup of=/dev/sdb
bs=446 count=1

Having read your earlier posts, I believe you are quite capable of sorting out Q0 and Q1. For Q0 though, I normally use pmagic live CD. For Q2, I once ran some tests to determine the optimum blocksize to use with dd and discovered that anything over 4096 didn't increase throughput much. However, I still use 4M when working with dd to dump a hdd image: dd if=/dev/sda of=/path/to/hdd-image-file.img bs=4M After dumping the image, refer to testdisk wiki [0] on how to mount the image file. If you require some hand holding working with testdisk, please contact me off-list. Cheers, ak.
