Firmware

Firmware version 3.01 for HP CD-Writer Plus 7200 Drives Download

This firmware update fixes the following issues:

• Disc at Once (DAO) writes a bad TOC (Table of Contents) on audio CD's.
• During the dummy write process (or sometimes referred to as 'write emulation'), the drive would (unintentionally) write something to the calibration area of a CD-Recordable disc. This would render an unusable disc after performing 99 times a dummy write to the same disc.
• Disc type ID is read from the disc (PMA lead-in). This can prevent the option of being able on other recordable drives to append to a disc that has been written by the "HP CD-Writer 7100 series"
• Some problems have been observed with resetting a computer system that runs Windows NT 4.0: Sometimes after resetting this system, the drive would not respond correctly, which then resulted in the fact that the disc is not visible in the Windows Explorer.
• Playing Video CD discs under Win 95 renders choppy video (video breaks up, jerky movement)
• Certain Toshiba drives cannot read discs because of an error in the Table of Contents (TOC)
• Issue that causes multi session CD-R's created with the 7100 and 7200 products to be unreadable by a large majority of CD-ROM devices.
• Multi Read Pre-gap
• 6x video Read.
