Hard drive integrity if cmos incorrect

By cedricfisher ·
We have some older systems that need hard drive replacements. The only drives available are to large for the cmos bios settings. We will be buying larger hard drives and configuring the coms settings so that the system sees it as a smaller drive. Wedo not want to upgrade the bios (requires re-validation effort). The question now is: 'Can anyone point me to hard data (something in print some where) that the drives will function properly or that the drives are destined for data integrity issues'?

Many drive manufacturers (including Maxtor, Western Digital and Seagate) include software with their drives that will allow you to use the maximum capacity of the drive even if the BIOS won't recognize it. As long as you install this software properly, you shouldn't have any problems.

The only problems I have seen is when this software is installed and later the drive is wiped and installed on a computer whose BIOS will recognize the drives capaciity. A simple Fdisk and reformat will not also eradicate the drive software. It must be removed with the provided uninstall routine.

Go to western digital and search their bios patch, ibm.com has a connection to OnTrack etc. an about from ontrack should do the job for you otherwise look to the other manufacturer's sites for their bios fixes sites.

Not hard data, but where I work, a number of production test PCs are set up as you describe.

We have not seen any problems.

May I suggest adding PCI bus IDE controller cards to these older systems.
For around $30 per PC, you will get the fullcapacity of the drive along with faster file transfer rates.

If the data is sensitive/important I would recommend upgrading the computers since they are relatively very inexpensive in comparison to the past.

If that's out of the question install a drive manager like Western Digital EZ drive.

"Another reason is because your BIOS has limits. 386 and 486 and lower end Pentium systems have limits of 512MB. Some Pentium Systems are limited to 2GB, and some of the newer ones, are limited to 8GB. It?s all in how the BIOS address the clusters on the Hard drive. It can be corrected with software, that comes with most new drives, like Western Digital?s EZ Drive, and Quantum?s Disk manager just to name a few. They take over where your real BIOS can?t perform, and then addresses the hard drive correctly"

Use a drive overlay. Most of the drive
manufacturers provide one either on disk or
on their website.
Unless you know the what to set to, if you set
to the wrong cmos you can kill the harddrive.
