Verbatim 52x CD-R 74min

The CDSpeed utility does not correctly recognize the disc as you can see in the image below. The specific disc is not a CD-RW but it's a Verbatim CD-R 74min 52x.

- Writing 48X CAV

• Average Writing Speed: 37.13X
• Writing time: 02:31 min

- Reading 40X CAV

The reading speed dropped in the end of the data area. That's an indication of a low writing quality there.

- Writing Quality - iQB OMNI

It is obvious that the quality of the specific disc is low. Many errors were reported after the 49mm radius of the disc. Most importantly, the E32 count (C2 uncorrectable) reached the 360. It seems that the drive has not been optimized to use the popular Verbatim CD-Rs.
