What Is This Tool?

This converter allows you to convert data transfer units between IDE (UDMA mode 2) and IDE (PIO mode 2), two legacy transfer protocols used by older PATA/IDE hard drives and optical drives. It helps interpret or configure device settings related to these transfer modes.

How to Use This Tool?

  • Enter the value in IDE (UDMA mode 2) units that you want to convert.
  • Select IDE (PIO mode 2) as the target unit for conversion.
  • Click the convert button to see the equivalent value in IDE (PIO mode 2).
  • Use the results to interpret legacy device timings or troubleshoot performance.

Key Features

  • Converts between IDE (UDMA mode 2) and IDE (PIO mode 2) data transfer units.
  • Supports configurations and diagnostics for legacy PATA/IDE hardware.
  • Provides conversion based on theoretical maximum transfer rates.
  • Facilitates understanding of device BIOS or driver-reported modes.
  • Browser-based and easy to use without software installation.

Examples

  • 1 IDE (UDMA mode 2) equals approximately 3.98 IDE (PIO mode 2).
  • 0.5 IDE (UDMA mode 2) converts to about 1.98795 IDE (PIO mode 2).

Common Use Cases

  • Configuring legacy PC BIOS or drive-controller settings for ATA/33 (UDMA mode 2).
  • Diagnosing why devices fallback from DMA to slower PIO transfer modes.
  • Interpreting drive throughput benchmarks indicating UDMA mode 2 capability.
  • Troubleshooting compatibility issues in vintage PATA/IDE systems.
  • Reading device reports showing which PIO mode an IDE drive uses.

Tips & Best Practices

  • Use this converter when working with older PATA/IDE hardware configurations.
  • Check your device or BIOS documentation to understand supported transfer modes.
  • Employ conversion results to diagnose performance bottlenecks or compatibility problems.
  • Remember this tool is meant for legacy systems, not modern SATA or NVMe devices.
  • Verify device driver and firmware settings align with intended transfer modes.

Limitations

  • Conversion is primarily relevant for legacy PATA/IDE systems, not modern interfaces.
  • Theoretical transfer rates do not guarantee actual throughput due to hardware variables.
  • The conversion factor is approximate and based on maximum theoretical speeds.
  • Real-world performance can be affected by hardware condition and driver implementation.

Frequently Asked Questions

What does IDE (UDMA mode 2) represent?
It is an Ultra DMA transfer mode known as ATA/33 used by legacy PATA/IDE devices offering a theoretical max transfer rate of about 33.3 MB/s.

When would I use IDE (PIO mode 2)?
PIO mode 2 defines CPU-driven data transfers and is used in older IDE devices or when systems fall back from DMA to programmed I/O cycles.

Is this conversion applicable to modern SATA or NVMe drives?
No, this converter is meant for legacy PATA/IDE hardware and does not apply to modern storage interfaces.

Key Terminology

IDE (UDMA mode 2)
An Ultra DMA transfer mode known as ATA/33 providing a maximum theoretical data transfer rate of about 33.3 megabytes per second for legacy PATA/IDE devices.
IDE (PIO mode 2)

PATA/IDE
Parallel ATA interface, a legacy hard drive and optical drive connection standard used before SATA.
DMA
Direct Memory Access, a method allowing hardware to transfer data without continuous CPU intervention.
PIO
Programmed Input/Output, a CPU-driven method for data transfers in older storage devices.
