wrong Hard drive reading

[Morgoth]

Ive got 2 hard drives 1 a 40gb hard drive the other a 120gb hard drive im using windows 98SE, but my 40gb hard drive reads as a 37.2gb hard drive and my 120gb hard drive reads as a 115gb hard drive why is this please

Where are you reading this from?

Also, is your Video Card sharing any of your memory?

Do you know if the hard drives are formatted as FAT 32?

Also Hard Drive space can be read several different ways.

Binary and decimal:

Some drive manufacturers have determined that 1 megabyte is the equivalent of 1 million bytes.

Other manufacturers call 1 megabyte the equivalent of 1024 bytes times 1024.

By using the '1 million bytes per megabyte' rule, a drive can be described as being larger.

Example for a 120MB drive:

1MB= 1 million bytes 120MB drive
1MB = 1024*1024 bytes 117MB drive

The drive ratings are the most confusing since the rating system is subjective. DOS normally reports megabytes available using the 1024 * 1024 rating system. Both rating systems result in the same storage capacity. One Byte of data uses one Byte of hard drive space regardless of how many Bytes per megabyte the manufacturer says there are.

The larger the drive the more the difference.
