Exact model	CRX140E
CD-R write	8×
CD-RW rewrite	4×
CD-ROM / CD read	32×
Recorded/read formats	Writes CD-R and CD-RW; reads CD-ROM/CD-DA and supported CD-R/RW media. Additional XA, multisession, Video CD or Photo CD access depends on disc format and host software; test the original application workflow.
Recording modes	Disc-at-Once, Track-at-Once and multisession support depends on the recording package and media. The maximum 8×/4× ratings are not guaranteed on every blank disc or in every recording mode.
Interface / mechanics	Internal IDE/ATAPI, half-height 5.25-inch class; host connection uses the IDE interface rather than SCSI. Set the drive select jumper according to the host channel and installation guide.
Host and operating-system compatibility	Requires an IDE/ATAPI-capable host and compatible optical/recording software.

Firmware / revision notes	Firmware and OEM bundle support vary by CRX140E revision. Record the complete model/firmware string and use only a matching Sony/OEM image. Do not assume that another CRX140 suffix has the same firmware or host interface.

Compatibility & preservation notes

Requires an IDE/ATAPI-capable host and compatible optical/recording software. For legacy Windows installations follow the Sony setup guide; current operating systems may read the drive through a bridge but do not necessarily support period recording utilities.
Firmware and OEM bundle support vary by CRX140E revision. Record the complete model/firmware string and use only a matching Sony/OEM image. Do not assume that another CRX140 suffix has the same firmware or host interface.
For an imaging or recording session, log the exact drive and firmware, interface/controller, operating system, application version, media identifier, selected mode and any read/verification errors. Keep checksummed image copies and logs.
Handle discs at the edge or center hole and store in cases in a cool, dry place away from direct sunlight. Avoid adhesive labels, abrasive cleaning and undocumented solvents or polishing.

Read support is not write support. A format listed for this drive does not guarantee every disc revision or copy-protection scheme will work.
