Data Recovery Tutorial: How to Slave a Hard Drive

This is a tutorial from Jacqui Best about the proper procedure for slaving your hard drive prior to running data recovery software on it. This would also be the procedure to follow if you were to run speed clone to sector clone a noisy drive or if you have a partition problem and need to repair or recover data from a partition or if you need to restore or undelete a file.
It is very important to not download data recovery software directly to the effected hard drive. If you don’t have a second drive or don’t have either a USB drive or USB capable data recovery software, then you must hook the drive up as a slave to run the software.

Case Study: How to “Slave” your Hard Drive
In data recovery it is NEVER a good idea to install, copy, surf the Internet, reboot the machine, or do ANYTHING on the hard drive you are now trying to recover the data from. I often tell customer they need to Slave the hard disk to another computer, or put it in a USB chassis. What is difficult is the fact that the average home user has no idea how to do this, and it can be a very daunting task.
With SATA you put the second drive in the second port. And check in the BIOS to see that it is indeed the second device and the first device is the boot .
You said you do not have another system you can use.
So start your build with another drive, install Windows 7 and go from there. Don't put the old drive in until you are sure everything is good with your new build.
The file system is NFTS on the old drive. Windows 7 would not have any problem reading data from it.
And of course, we never plug and unplug internal components unless the
power cord is removed from the PSU.
The programs installed on the old XP system are, for the most part, not portable. That means the will not run in Windows 7 until you re install them.
There is no problem using one drive as a system drive and another as a data drive. People do it all the time. Slight increase in power consumption and heat .
Along with slight increase in performance.
