: Hallo from sunny South Africa, Cape Town

: I installed a 15 gig harddrive on a old PC. When I auto detected the new drive it only showed 8 gig (bios to old). Knowing the cylinders and the sectors I manually entered them. This gave me a 14 gig drive. It should have been 15 odd gigs. Then, clever as I am, partioned the 14 gig drive into two 7 gig drives. Now I struggle to get the original 15 odd gigs back in my new PC that support big drives.

: In my new PC's bios the hd auto detects correct parameters. I removed the partitions and reformatted the drive but still no luck.

: What must I do?

I don't think you lost anything. Make sure you are comparing HDD size on the right basis. Typically, HDD makers advertise HDD size as a DECIMAL number (1 GB = 1,000,000,000 Bytes) but CMOS, format and other programs usually report on a binary basis (1GB (1,024)*(1,024)*(1,024). One GB binary basis figures out to be about 1.074 GB Decimal, so: 1.074*14 = 15GB = Cylinders*Heads*Sectors*512

If you like, you can clean your HDD thoroughly by using the HDD maker's pseudo low level format utility from teh maker's web site.

Hope this helps,
Henry
