Lenovo 6458362 Ultrabay Slim DVDRW Internal Drive

The Lenovo 6458362 is a Serial Ultrabay Slim DVD-MULTI IV internal optical drive built as a direct replacement module for select ThinkPad laptops. At 9.5mm thick, it matches the Ultrabay Slim bay dimensions found in the T400, T410, T420s, T500, and T510 series. The DVD-MULTI IV designation means full read and write support across DVD-R, DVD+R, DVD-RW, DVD+RW, DVD-RAM, CD-R, and CD-RW formats — essentially every mainstream optical disc format short of Blu-ray. The Serial Ultrabay interface provides a SATA connection to the laptop's internal bus, delivering reliable data transfer without the bandwidth limitations of older PATA Ultrabay designs.

This drive is purpose-built for ThinkPad users who still need optical media access — whether for legacy software installation, data archival on DVD-RAM, or reading client-supplied discs. The hot-swap capability of the Ultrabay Slim bay means you can keep this drive on hand and swap it in only when needed, running a secondary battery or HDD caddy the rest of the time. It is a maintenance and replacement part, not an upgrade, so expectations should be set accordingly: it restores factory optical capability to a supported ThinkPad, nothing more. For users working with these specific laptop models, it is the correct OEM-spec component for the job.
