I recently had to replace my IQ526 DVD drive as it would no longer write to a disk and wanted to do the same thing. The 'Parts Smart' site shows the Blu-ray unit part number but it is not available to purchase (no selection box). I was able to buy a new LightScribe unit...my failed drive was not LS...from the site and it installed w/o any issues. I searched extensively for a Blu-ray replacement drive but it is not possible to acquire one. From the other threads, it would seem to be another case of 'buy upfront or perish.'

Thank you Diane. I did check there but wasn't sure if it was the right drive for my configuration/model. Didn't want to plunk down the cash for something that I wasn't sure would be the correct spec. It would be helpful if there existed a table of all TS-T633(x) internal DVD writers that are compatible with the many variants of the HP T/S machines. The ones I found cautioned that they would only work with Dell computers even though it was the same basic drive number. It would seem that the TS-T633x drive is custom tailored to many manufacturers. I could not find one on eBay using the HP part number but maybe that's just me.

Best regards,

Les
