1- U may disconnect the failed HDD from PC1 and attach to another PC as a slave disk. Beware of Jumper settings. Start the 2nd PC.
2- Install Acronis True Image on P.C 2 may need to restart P.C
Open da ACRONIS program/click on Backup/disk image/locate HDD of P.C1/click next/and locate where you u want to put the image on P.C 2 (desktop or any location u prefer)

when you finaly get da image, get yr new HDD and plug it in P.C 2. use the acronis again to recover.
1- Open Acronis program
2- Recovery/ click on disk recovery/locate the image you made/click next/tick recover whole disk partition and click nexttick all partition and click next/select ur new HDD And proceed. when it recovering complete, shut down computer and now you can use it again for your P.C1..no changes meade to ypu O.S or your files.

1. Before starting to backup a drive image to another drive, both drives should be partitioned. you need a secondary partition with enough space to copy the image into. Once this is done the backup can begin, and only the primary partition should be copied. Any hard disk backup imaging/copying software should work. I’ll leave it to you to select the imaging software you are going to use. Some will backup the drive image to the PC, while others want to write it directly to DVD disks (my prefered methd.)

2. The imaging of an active hard drive will not work, because of the writes the OS makes to the virtual disk on the hard drive while working. Because it changes, the Imaging software gets confused. So either put the drive into another PC, as a slave, or use Ghost. I use an old version of Ghost, my version of ghost loads a ram drive and it’s own OS, so the host OS is not run from the hard drive. That means I can copy the drive in situ. Down side is, I have to copy to DVD disks, as it won’t copy to a drive location.

3. The size of the disk you want to image, the size must be able to fit on the drive to which you are copying it to. (You won’t fit a 200gig HD on a 100 gig.) Obvious, but often not thought about until doing the job. (Compression is definately needed as there will be a lot of blank space on the source HD.)

4. Whether the drive you are going to move, can be read by the PC you are fitting it to, (SATA or PATA connections, both preferably.)

If your drives aren’t big enough, or you don’t want to partition them, then I suggest maving the image to DVDs. You may need about 20, all the same batch, to be on the safe side.
