ok the hard drive should have some info about the cylinders on it.
see if they match the info you have.
I think the limitation is the number of cylinders.
some BIOSes erroneously allocate only 12 bits for the cylinder field in CMOS RAM.
Cylinders limit is 4096 cylinders numbered 0-4095 (12 bits)
Heads limit is 16 heads numbered 0-15 (4 bits)
Sectors limit is 63 sectors numbered 1-63 (6 bits)
4096 x 16 x 63 = 4,128,768 sectors
4,128,768 x 512 = 2,113,929,216 bytes 2.1GB (1.97GB)
some disk drives come with a jumper to make them appear 4092/16/63
look for a jumper on the drive
what is the model serial number and manufacturer
