Fastfat.sys crash on XP installation

Specs: Windows Vista
I have had to install a brand new hard drive on my PC and need to reinstall XP. All is OK and I got to the stage where I formatted the hard drive with no problems. Then the blue death screen apeared and since then, Windows Setup loads all the files etc. but then stops with the fastfat.sys error mesage.

Is there any way around this problem? I have tried putting the CD ROM first in the boot sequence and the hard drive first, but get the same result either way.

Is it feasible to load the install CD in another PC and extract fastfat.sys, then install it on the PC hard drive prior to loading the install CD?

I'm a novice technically, so any advice would be more than welcome!

That file seems to be related to external devices. Do you have any USB storage devices connected while installing WinXP?

How partition and format the new drive?

Thanks for the reply. I have no USB storage devices - just an infra-red controller for a remote keyboard and mouse. I partitioned and formatted the new drive via Windows Setup and went for the full format. That took about 1.5 hours and succeeded. The first crash was after that point, but I must admit I didn't take much notice of the error message that time. Each time since, all the Windows files get created and the crash happens when Windows setup would normally go to the page about formatting/partitions.

I had expected at that point to simply proceed with the installation.

Why did you need to install a new hard drive in the first place?

Did the wireless combo work during the installation?

Was the computer originally running WinXP? Do you have a SATA type hard drive? Is the new hard drive properly identified by both the model and FULL capacity in the start up screens?

I'l try and answer the questions! The original hard drive got completely corrupted and was unusable. There had been increasing numbers of crashes on that one, so I took the decision to replace the hard drive. I will use the old hard drive via Explorer to get the files I need once the new one is working.

The wireless combo works fine during installation.

The new hard drive is a SATA type - Western Digital WD5000AAKS 500GB SATAII 7200RPM 16MB Cache - OEM Caviar Blue. The start up screen definitely shows the full capacity - sonmething like 498500MB from memory.

I was wondering if I could use Explorer in my laptop to take a copy of fastfat.sys from the install CD then maybe install it to the new hard drive via a memory stick. But I haven't worked out how to get a C prompt in order to do that, so any further comments would be welcomed.

WinXP does not support SATA controllers. You either need to supply the drivers at start up, slipstream the drivers into your CD files, or if available, Set the BIOS to run the drive in an IDE mode. Not sure if this is related to your issue or not.

What type of WinXP CD are you using and was WinXP running on the computer originally?

When installing WinXP did you get any messages about Windows not being able to copy any files?

Is your CD scratched or dirty? If dirty wash with warm soapy water and gently dry.

Some system specs, or model numbers would help.

Hi again,

I've had a go at all the things mentioned. I think I will wait till next week when my son returnrs from vacation - he is a Support Manager and hopefully should be able to use his experience to sort out the issues. Thanks for all the advice though - at least I have tried to respolve the problem with your help, so won't be accused of being an old fossil!!!
