Built for Vintage Systems

This genuine Maxtor OEM drive was commonly found in 386, 486, and early Pentium desktop computers. It works perfectly as a primary or secondary drive in retro PCs, period-correct restorations, or DOS/Windows 3.1/95/98 gaming and productivity machines.

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

Here are the key specifications (compiled from archived Maxtor/Seagate DiamondMax 10 PATA product manual, data sheets, and vendor listings):

• Capacity: 100 GB (100,000,000,000 bytes / 100 × 10⁹ bytes; approximately 93 GiB usable after formatting)
• Form Factor: 3.5-inch
• Interface: Ultra ATA/133 (also known as ATA-7 or Ultra DMA Mode 6) — maximum burst transfer rate up to 133 MB/s (backward compatible with ATA/100, ATA/66, etc.)
• Spindle Speed (RPM): 7,200 RPM
• Cache / Buffer: 8 MB
• Average Seek Time: ~9 ms (typical read; Maxtor spec lists 9 ms average)
• Average Latency: ~4.17 ms
• Sustained Data Transfer Rate (outer zones, max): Typically ~60–80 MB/s (varies by zone; good for the time due to density and cache)
• Internal Data Transfer Rate (max): Around 700–900 Mbit/s (~87–112 MB/s theoretical, sustained lower in practice)
• Bytes per Sector: 512
• Guaranteed Sectors: Approximately 195,352,516 (exact for 100 GB models in the series)
• Number of Platters / Heads: Typically 2 platters / 4 heads (using high-density ~50 GB/platter technology)
• Power Connector: Standard 4-pin Molex (IDE power)

Here are the key specifications, compiled from official Maxtor/Seagate datasheets, product manuals, and consistent retailer listings:

• Capacity: 200 GB (formatted; actual usable space slightly less due to binary vs. decimal calculation — LBA sectors: 398,297,088)
• Interface: IDE / PATA (Ultra ATA/133 or ATA-7; backward compatible with ATA/100, ATA/66, etc.; max theoretical burst transfer rate 133 MB/s)
• Form Factor: 3.5-inch (standard desktop, ~1-inch height)
• Spindle Speed (Rotation): 7200 RPM
• Cache / Buffer: 8 MB
• Average Seek Time: ~9 ms (read/write typical; includes settling time)
• Platter/Head Configuration: Usually 2 platters (some variants may vary slightly)
• Other Features:
  • Shock Protection System (SPS) and Data Protection System (DPS) for improved reliability
  • Quiet Drive Technology (QDT) for reduced acoustics
  • Supports Native Command Queuing (NCQ) in some configurations (though limited benefit on PATA)
  • Fluid Dynamic Bearing (FDB) motor for quieter and more reliable operation
• Power Consumption: Typical for the era (~6–9W active/idle; uses standard 4-pin Molex power connector)
• MTBF (Mean Time Between Failures): ~1 million hours (manufacturer rating for the series)
• Compatibility: Works with older motherboards featuring IDE controllers; jumper configurable for Master, Slave, or Cable Select (CS)

Here are the key specifications based on official data sheets, product manuals, and consistent listings:

• Capacity: 40 GB (formatted LBA mode; note that actual usable space is slightly less due to binary vs. decimal GB calculation common in that era)
• Interface: IDE / PATA (Parallel ATA), Ultra ATA/133 (also backward compatible with ATA/100, ATA/66, etc.; max theoretical transfer rate 133 MB/s)
• Form Factor: 3.5-inch (standard desktop/low-profile ~1-inch height)
• Spindle Speed (Rotation): 7200 RPM
• Cache / Buffer: 2 MB
• Average Seek Time: ~10 ms (read/write; typical for the series, with track-to-track seek lower)
• Platter/Head Configuration: Often single-platter, single-head design for this capacity point (one of the first mainstream single-platter 7200 RPM drives)
• Other Features:
  • Fluid Dynamic Bearing (FDB) motor for quieter operation and reliability (important for desktop/PVR use)
  • Shock Protection System (SPS) and Data Protection System (DPS)
  • Acoustic performance optimized (seek noise reduced via licensed technology)
• Power Consumption: Typical for the era (e.g., ~5-7W active; +5V and +12V rails via standard 4-pin Molex connector)
• MTBF (Mean Time Between Failures): ~1.2 million hours (manufacturer claim for the series)
• Compatibility: Works with older motherboards supporting IDE/ATA; jumper settings for master/slave/cable select
