Description
Seagate ST320014A 9W1021-302 20GB IDE PATA 3.5" Hard Drive Low Profile HDD
The Seagate ST320014A is a 20GB parallel ATA (PATA/IDE) internal hard drive in the low-profile 3.5" form factor. Part of Seagate's U Series X line, it uses the standard 40-pin IDE interface and 4-pin Molex power connector found on desktop motherboards and optical drive controllers of its era. The low-profile 0.75" height makes it compatible with chassis that cannot accommodate a full-height 3.5" drive.

Applications
The Seagate U Series X was a mainstream desktop hard drive line targeting the late 1990s to early 2000s PC market, when PATA/IDE was the dominant storage interface before SATA became standard. Drives like the ST320014A are commonly used today in retro PC builds, vintage gaming rigs, and legacy industrial or embedded systems that require a parallel ATA drive. The low-profile height is particularly useful in compact or slim desktop enclosures where a standard-height drive won't fit. These drives are also a practical choice for restoring older workstations and systems running Windows 98, Windows ME, Windows 2000, or early Windows XP — operating systems that were designed around the ATA/IDE storage standard and may have compatibility considerations with larger, modern drives.
This Seagate ST320014A 20GB IDE internal hard drive has been tested, formatted, and wiped at our facility and is in good working condition. All previous data has been securely erased. The drive shows normal cosmetic wear consistent with prior use — light scuffing on the top label and housing typical of a pulled drive. The PCB and connectors appear clean and intact.
