Hello.

I have had this Lenovo W530, from work, since June 2015. I finally
started using its internal Mat****a DVD-RAM UJ8C0 (SB01) disc drive to
burn to small old CDs (unused CD-Rs & CD-RWs) recently. However, IT's
preinstalled 64-bit Windows 7 EE SP1's system image creator and
downloaded ImgBurn v2.5.8.0 (with a downloaded 247 MB ISO file) could
not fully write to my CDs. I had no problems erasing my old CD-RW. I
tried copying a very old burned 650 MB CD-R to its local SSD, and it was
fine. So, it sounds like this physical drive has write issues? Or is it
something else?

Thank you in advance.

Probably bad discs. Hold them up to a light and see if there's
discoloration (rust spots) or pinholes. This is CD rot and quite common
on cheap CD-R brands.

Are Sony, OfficeMax, etc. cheap brands?


I used to use no-name brands for years and checking the ATIP information
on the disc, they were usually CMC Magnetics and the discs were bad
after a year or two. Since then I moved to Taiyo Yudens, bought a whole
distributor case and haven't had an issue to this day.

Ah. However, I did think I fixed it by upgrading the drive's firmware
from Lenovo. So far, no coasters.
