Question about Dell DIMENSION P3/866MHZ 128MB 20GB DVD L866R PC Desktop

2 Answers

I am replacing the hard drive in my Dell Dimension L866r

I bought a WD Caviar 350 GB HD. I removed the jumper because it is the only HD on the system. I used Win XP (SP1) setup disks to partition HD. It designated the HD as Drive: C. I inserted the XP (SP1) CD in the CD slot. The setup program loaded the XP operating system on the HD and then did a restart. Upon restart, I get an error message that indicates a file error. It appears that the system is looking for the boot file in the A drive (disk), instead of the HD. When it's not finding anything, it produces the error message. Any suggestions???

    I am using the original 40 pin ribbon for the new HD, not a newer cable, so cable select is not the solution. System would not boot when using the OEM MS XP (SP1) CD when first trying to format the HD, so that is why I had to download the 6 diskette Setup files from the Internet and use them. After the Setup diskettes allowed me to format the HD and partition it, it seemed to load the XP operating system on the HD (the light kept flashing), but when it rebooted at the completion of the load, I got the error message on startup that there was an error reading the file. I have reloaded the computer 3 times with the same results.On startup, the HD only flickers once and then it immediately goes to the disk drive (A) looking for files.

    Have you tried putting the jumper on the hard drive to Cable Select (CS)?

You say tht you used setup disks and then you used an XP disk. This is a little confusing.
You should have (maybe you did--but I can't tell from how you wrote the question) booted the computer from the XP disk and let the setup run from it--choosing to partition if you so desired (I am not a fan of HD partitioning). Once the setup files were installed and the system rebooted, the setup should have continued. If you did use floppy disks, that may be the problem (but I personally have never seen XP floppy disks--unless they were proprietary computer disks) used for this purpose.) In your case, proprietary disks probably wouldn't work because you are using a larger drive than the manufacturer had originally installed.

    You have to use a newer high-density IDE cable for this drive. If you ask me why, I can't tell you the technical reason, but it works better than the old 40 pin)
    You say the system will not boot with the CD. This sounds like you have to enter the compute setup (bios setup) and look for the menu option that allows you to set the boot order of your devices. The computer is obviously set to boot from the floppy first and then the HD. You need to set it to boot from FD and then CD and then HD.
    Give that a try.

Do you have a floppy drive in the drive if so remove it. Also turn off your floppy drive or just remove it completely it could be bad sending false info to the main board saying there is floppy drive in the computer. Also try and turn the drive off in the BIOS

I prefer the Caviar Black, but most of all am very supportive of your going with Western Digital. They have the best and most generous support to direct consumers of all the HD manufacturers. I've received several replacement drives for ones that failed under warranty over the years for customers without a hitch. There warranty site is easy and quick to use and they are lightning fast at getting your drive to you.

Reinstall your old hard drive as master and install the new hard drive as slave.

Here is the link to jumper settings from Westrn Digital;

If you've got your jumper settings wrong and installed your os on the 127 GB section of the 320 GB Hard drive and you change jumper settings and then you have problems you may need to reinstall the old hard drive as master and the new hard drive as slave. Reformat the new hard drive as 320 GB, and as a bootable drive. You can either do a disk copy from old to new or reinstall your os on the 320 GB drive. Please let me know how this goes. You can get to me @

Have maxtor 40gb hd want to add 2nd WD hd in DEll dim8200

(if both drives on the same cable):
Your boot drive goes at the end of the primary data cable.
Your second drive goes on the middle connection of the same cable.
The red stripe on the data cable needs to be closest to the power connection (red stripe to pin 1).
The jumper on the boot drive set to master.
The jumper on the second drive set to slave.
Look in the BIOS to make sure it sees both harddrives.
Boot the system.. it will need to be partitioned and formatted if not already..

I guess there is nothing with BIOS since it identify your Western Digital Caviar Hard Drive. Try changing the jumper setting of this Hard Drive by reading the Instruction that comes along when you purchase. Otherwise you can visit the Western Digital website and click on Support-Knowledge BASE...
