Hi!

There may be a few issues at work here. Have you tried anything like enabling DMA using a cheatcode? There have been many issues caused by the drives requiring DMA to function properly. I have a similar issue with another model Hitachi-LG drive in a notebook. Enabling DMA has resolved it.

If I am correct, it is a small form factor PC using a slim cd/dvd drive. I don't know of any suppliers for these drives in the UK, but have seen some exact replacements on eBay from time to time. I believe that Newegg.com has replacements that would work in place of what you have. Another model of Hitachi-LG/Goldstar would probably work well and might accept all of the trim/mounting attachments without modification. If it is a standard slim format drive, almost any manufacturer's drive might work.

Good luck and hope you resolve your issue.
