First-generation DVD+RW drives were to use phase-change rewritable technology to store 2.8 GB per side. DVD+RW manufacturers formally abandoned the 2.8 GB DVD+RW 1.0 standard in late 1999, without ever having produced drives in commercial numbers. Second-generation DVD+RW drives, which finally shipped in volume in late 2001, expand capacity to 4.7 GB per side and support writing CD-R and CD-RW discs. DVD+RW discs are readable by most recent DVD players and DVD-ROM drives, although as with DVD-RW the lower reflectivity of DVD+RW discs causes some devices to mistake them for dual-layer DVD-ROM discs and therefore refuse to read them. A firmware update solves that problem in many drives and players that experience it. Roughly 65% of older DVD-ROM drives and DVD players can read DVD+RW discs.
