Ability to read usually erodes in my experience long before ability to burn.
Sounds like you bought the wrong drive in the first place.
There ARE wrong purchases out there. I have a burner in my laptop for instance. Came with the laptop. I won't be using it to burn anything important.
Sadly my good burner in the PC is failing slowly. Well mostly the load and eject drive seems damaged. Burns just fine, reads ok. I just need to use a pin to prod out the drive for the most part.
But when I bought it, it was the acknowledged darling of the disc burning world. It was THE right brand and model to buy, as IT would burn anything at that time.
Today a blueray drive will likely make it eat dust.
Considering common no frills burner drives cost so little, if yours is not working, the right choice might be to just treat yourself to a new one.
They cost less than most schlock bargain bin games now.
As for extending the lifespan of drives, don't use them.
If you have a game disc, use a drive emulator and then run a pretend image of the disc in a pretend drive and spare your drive the need to be running.
I NEVER use discs that need to be in the drive and running constantly. And as a result, my computer gets replaced long before the drive dies on me.
