Data encryption, disk scrubbing and windowsXP

Specs: Windows XP
I am in the process of selling my laptop and need to completely clean off the hard disk to protect myself against data digging for deleted information. I decided to encrypt the data before I reformatted the drive. My brother suggested that I also do a disk scrubber before reformatting. So after I successfully encrypted the data I began the disk scrubbing with Kill Disk. Part way through the first pass it stopped and wouldn't continue. I had to press the power button and restart the computer. That is whent he problems began. I attempted another disk scrub pass but it wouldnt start. Then I tried re booting from the data encryption disk. After trying I had restart the computer again and then it has stopped recognizing the hard disk. I tried re booting with my XP disk and dried both setting up and repair. I got the message "Set up did not rind any hard disk drives installed." I can't get anywhere on the computer except the BIOS set up utility, the boot disk from the encryption software, and the start of XP set up. (at least that is all I know how to try) What do I do now? I have got to get this computer up and running before the buyer comes to pick it up.

Yes you will have to get Windows working on it again - no sensible person is going to buy a second-hand PC unless they can see it working properly.

The copy of Windows that was pre-installed on that laptop at the factory is tied to that laptop for the rest of it's life and should by rights remain installed on it when you sell it.

There are two possible reasons I can think of why Windows XP Setup cannot now find the hard drive:

1. Since wiping all data off it, if it's a SATA hard drive, the driver for the hard disk SATA controller is no longer present. Since Windows XP does not support SATA disks natively, you need to re-install the SATA driver during XP Setup by pressing F6 and telling XP Setup where the driver is on a pre-prepared floppy disk. See this:

2. If it's a standard IDE-PATA disk (not SATA) the above does not apply because XP Setup doesn't need a third-party driver for standard IDE-PATA disks. In this case if you get "No disk found", the disk itself may have failed or is not connected up properly (unlikely on a laptop). A failed disk will have to replaced by a new one.

Do you have restore disks for the laptop?

Killdisk most likely wiped the entire drive, including any hidden partition.

Does the BIOS identify the hard drive in the POST screens at startup? If so, then the issue may be one covered in #1 above. If the BIOS is NOT identifying the drive then read the next paragraph.

Killdisk can stress the hard drive because it is writing to every part of the drive. This MAY have damaged the drive, in which case you would need to replace it.

You could try running a hard drive fitness test on the drive. Get the utility from the manufacturer of the drive. Hitachi's test supposedly works on any brand drive but I can't verify that statement. Toshiba doesn't have a fitness test.

I have the XP disks and a CD titled Utility CD version 1.1. I don't have any flopy disks. When i tried pip 22's first suggestion It brought me to the screen saying "Setup could not fnd a flopy dive on your machine to load OEM drivers from flopy disk." How do I do this with out a flopy drive? In the BIOS Utility I was able to see a Toshiba hard disk. I tried doing pulling out the XP CD and put in the "Utility CD" and I can't seem to get it to do anything more. I'd like to continue persuing pip22's 1st suggestion. It is a SATA drive.

I do have a 1 T external hard drive that I could hook up to the machine and try to get it up and running and some how access the internal drive in the lap top. Is that possible? I'd rather not involve my external hard drive in this operation, but if there isn't another way I could.
Thanks so much for helping so far. Any other suggestions and tips are more than welcome. Thank you.

If anyone know anything aobut the encryption side of the problem, here is what I am trying do to: I am trying to use the encryption rescue disk. When I am in the repair options menue I do the option for "Restore key data" and enter the pass word and follow my instructions. Then it brings me to "Write error:128 Drive 0 Sector 62." Does anyone know what that means and what to do about it? I found a "download error 128 tool on the internet from my desk top, but how will downloading that help me witht the lap top? I tried down loading and thought I could use my comp. net work to access the lap top and scan it from the desktop. So far I can't figure out how to do that. Any ideas

If you previously encrypted the data on the disk and then used killdisk with at least one path I wouldn't worry about anyone recovering person data.

That said, if you store things like bank account numbers and a password list on your hard drive I would recommend against doing that in the future. Your computer could be hacked or stolen. Instead burn that type of data to CDR.

Now to solve your issue with the re-installation.

What type of disk do you have? Is it a factory restore disk?

Do you have another computer with Win2000 or XP on it that also has disk burning capability? If so, you can make a new CDR that will include the SATA drivers using the original files from the CD you do have. The process is called slip streaming. A program called nLite OS makes it easy to do. Get nLite OS from the link below. You will also need to get a copy of the SATA controller drivers for your motherboard/computer.

You MAY not need to do any of that if your computer has certain BIOS options. Post the brand and full model of your computer.
