Description

The Seagate ST3802110A is an 80GB hard drive from the Barracuda 7200.9 PATA series, a mainstream/performance-oriented 3.5-inch IDE/PATA drive released around 2005–2006. This was one of the last major IDE/PATA desktop drive families from Seagate before the full shift to SATA, offering solid 7200 RPM performance for upgrades in Pentium 4 / Athlon 64 systems, gaming, and general use.

*** Hard drive is tested for good S.M.A.R.T. , no bad sectors and is formatted as an NTFS partition. Actual drive is pictured.

Here are the key specifications based on the official Seagate Barracuda 7200.9 PATA Product Manual (Rev. C/F) and consistent vendor/historical data:

• Capacity: 80 GB (formatted; actual usable space ~74–75 GiB due to binary vs. decimal calculation and overhead)
• Interface: IDE / PATA (Parallel ATA), Ultra ATA/100 (ATA-6), backward compatible with ATA/66, ATA/33, PIO modes, etc. → Max theoretical burst transfer rate: 100 MB/s
• Form Factor: 3.5-inch (standard desktop, ~1-inch / 26.1 mm height)
• Spindle Speed: 7200 RPM
• Cache / Buffer: 2 MB
• Average Seek Time: ~11 ms (read/write; typical value from manual and listings)
• Average Latency: ~4.16 ms (at 7200 RPM)
• Platter / Head Configuration: Typically 1 platter / 2 heads (using high-density ~80–100 GB/platter technology of the era; single-platter design for this capacity point in the 7200.9 lineup)
• Other Features:
  • Seagate’s SoftSonic motor (FDB or similar for reduced noise/vibration)
  • Enhanced G-Force Protection and shock sensors
  • S.M.A.R.T. support for health monitoring and predictive failure
  • Quiet operation focus (good acoustics for a 7200 RPM drive)
  • Supports legacy LBA addressing (16383 cylinders / 16 heads / 63 sectors in CHS mode for compatibility)
• Power Consumption: Typical for the era (~6–9W active; standard 4-pin Molex power connector)
• MTBF (Mean Time Between Failures): ~600,000–1 million hours (manufacturer claim for Barracuda 7200.9 series)
• Acoustics: Idle ~28–30 dB; seek ~30–34 dB (relatively quiet for class)
• Compatibility: Works with older IDE/ATA motherboards; jumper settings for Master/Slave/Cable Select (standard Seagate layout—check drive label: typically Master: jumper on specific pins (e.g., 7-8), Slave: no jumper, CS: jumper on pins 5-6 for cable-determined role; use 80-wire cable for ATA/100 speeds)
• Jumper Settings (typical Seagate Barracuda ATA):
  • Master (or single drive): Jumper closed on designated pins
  • Slave: No jumper
  • Cable Select (CS): Jumper on CS pins; recommended for modern installs

This drive provided strong performance for its time—sequential transfers often 50–70+ MB/s in outer zones, quick seeks, and better reliability/noise than many 5400 RPM alternatives. It was popular for budget builds, upgrades, and as a secondary drive alongside SATA in transitional systems.
