What did you replace the TSST Corp with?

An LG GH24NSD0 24x.

Glad its working. I hope you have not wasted your money.

I find I have no need for one nowadays, as most stuff comes off the net and I am lucky enough to have a decent connection. I think the only time I have used mine in the last couple of years was to burn a CD or DVD for others. As that is normally pictures and they normally have a computer or at least a USB stick, then that is the common method now.

In reply to a post by cheshire_man:

...It will burn and verify a DVD but when that same DVD, or any other DVD is inserted it completely fails to see it...

I think the verify process is questionable at best, I certainly wouldn't trust it if verified disks fail to read on the same drive.

The DVDs read perfectly well on my laptop. And I said the drive didn't even see the burnt DVD, so it never got as far as trying to read the data.

It could only ever 'see' a blank DVD or blank or written CD. A written DVD was to all intents and purposes a non-DVD to the old drive.

Anyway the old drive is now sitting in the bin awaiting tomorrow's bin collection.

If it couldn't see the burnt DVD how the heck could it verify it in the 1st place?

It's a moot point now that you have replaced the drive but I wouldn't trust the verify process.

I suspect the problem lay in the, unknown to me, process by which the drive, when the tray is closed, detects a disc This worked for CDs, blank or burnt; and worked for blank DVDs, but didn't work for ANY written DVDs, whether commercial ones or my DVDs.

The verify process doesn't open and close the tray.

The fact that the written & verified DVD was perfectly readable on my laptop suggests the verify process was OK. And having used Nero for many years I've never had an occasion when the verify process finished OK but the resultant disc was not OK.
