[ DVD-RAM WRITERS // IDENTIFIED MODEL ]
NEC ND-4570A
DVD-RAM read/write support with model-specific optical-media and host details below. Maximum speeds are ratings, not sustained guarantees; firmware, media revision and operating mode matter.
IDENTIFICATION: Match the full label, suffix, OEM part number and firmware against the cited documentation before installing, burning or using this mechanism for preservation reads. Closely named revisions are not assumed interchangeable.
Documented specifications
| Catalog subcategory | DVD-RAM writers |
|---|---|
| Exact model | NEC ND-4570A |
| Readable media | CD-ROM, CD-R, CD-RW; DVD-ROM, DVD±R, DVD±RW, DVD±R DL and DVD-RAM. DVD-RAM read/write ceiling is 5×; match supported versions and media in the manual. |

| DVD-RAM rating | Read/write up to 5×; actual operation depends on supported DVD-RAM version, disc condition, firmware and host software. |
| Interface / mechanics | E-IDE / ATAPI (PATA, Ultra DMA/33 class); 5.25-inch internal half-height. Check mounting, connector pinout, bay/caddy and power before installation; this record does not claim an unverified dimension or adapter pinout. |
| Host / software compatibility | Internal 5.25-inch half-height IDE drive. Requires an ATAPI-capable PATA channel, cable, power, and proper channel jumper settings. Use compatible burning software and DVD-RAM packet-writing/UDF support in the host OS; legacy BIOS/driver support can constrain boot or burn operation. |
| Model distinction | ND-4570A is the DVD-RAM-writing model; nearby ND-4550/ND-4551 and OEM labels should be checked individually rather than treated as identical. |
Media and host notes
- DVD-RAM is a rewritable random-access format, but only versions and cartridge types listed for the exact unit should be used; physical cartridge compatibility is not inferred from the DVD-RAM logo.
- For DVD-RAM drag-and-drop or packet-written use, confirm host UDF/filesystem and application support. A drive that can write DVD-RAM does not guarantee operating-system mounting or packet writing.
- Internal 5.25-inch half-height IDE drive. Requires an ATAPI-capable PATA channel, cable, power, and proper channel jumper settings. Use compatible burning software and DVD-RAM packet-writing/UDF support in the host OS; legacy BIOS/driver support can constrain boot or burn operation.
- Record drive label, firmware, controller, OS, software, disc version, write mode and verification result with each preservation image; retain checksums and error logs.
Protect recordable discs from heat, sunlight, scratches and contamination. Handle by the edge or hub and store in a case. Test each media batch before relying on it as the sole copy.
