It's very rare that we ship a wrong sized hard drive. If we did, you can return it for an exchange or refund. Some operating systems and BIOS are limited to certain sizes of hard drives. The BIOS limitation depends on the brand, model, and BIOS version of the motherboard. This is often caused by compatibility issues betweent your computer motherboard and the new memory module.
Some older computers allow only certain maximum memory capacity.
Adding another 32MB memory may have exceeded that limit. Some proprietary computers may not take standard memory at all. We suggest you do a few tests. First determine how much memory your computer reads before inserting the new module. Then, remove all the memory modules and insert only the new one to see how much memory the computer registers.
