Check in Disk Management, if you see 10 gig more there, then right click on it, format and create other partition.

Hi there. Used your suggestion, but it still only shows up as 10 GB. Thanks for trying.

Please check that model number again. There seems to be no disk with model # ST32001 that I could find.<br />

There is a tool called HDD Capacity Restore that may work. But drive must be connected to SATA intrerface, not USB and must be offline (not mounted with a drive letter) for it to work.

I bought a &nbsp;used 10 GB hard disk drive. The BIOS identifies it as 10 GB, but the model numbers ST32001 which is a 20 GB drive. &nbsp;The label says 20 GB. Is there any way to restore this drive to it's original capacity? &nbsp;

Restore HDD to full capacity

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.
