without burning out?<br>
<br>
I've been producing DVDs of historical primary source material (see, e.g., <br>
<a href="https://www.worldcat.org/title/moreygraham-historical-letters/oclc/904725729" rel="noreferrer" target="_blank">https://www.worldcat.org/title/moreygraham-historical-letters/oclc/904725729</a>) on my grandfather (see <br>
<a href="https://en.wikipedia.org/wiki/David_Crockett_Graham" rel="noreferrer" target="_blank">https://en.wikipedia.org/wiki/David_Crockett_Graham</a>). In March, I was about to head out to China for <br>
a three week trip, and I was pulling an all nighter producing DVDs of my latest project with 23 of <br>
his diaries. At 6am on the morning that I was leaving, my DVD drive took the usual length of time to <br>
burn a DVD (seems like forever), then it started the verification scan, took a long time and <br>
summarily spit out the DVD, saying it was unable to verify it. I went through 4 DVDs with the same <br>
result. This was from a stack of 100 good quality Sony DVDs that I had been pulling from for quite a <br>
while with no problems.<br>
<br>
At the point that the drive failed, I had been burning DVDs non-stop for well over 12 hours. All <br>
told on this round going back a couple of days, I had burned something like 50-60 DVDs. Previously, <br>
I had used the drive to burn other DVDs.<br>
<br>
This is not the first time I have had this experience. Maybe the third. (i.e. bought a new drive and <br>
then had it burn out.)<br>
<br>
I'm using an iMac which I think is about 2014, running MacOS Mojave, with an Apple USB Superdrive.<br>
<br>
Googling reviews of drives is pretty useless. They basically tell you they bought the drive, it <br>
hooked up without any trouble, it worked great, and it is built solidly; or something like that. <br>
They don't give long term wear and reliability. They don't say anything about non-stop burning <br>
sessions; just normal easy use with a brand new device. I asked this question of a "genius" at the <br>
Apple Store this weekend, and he didn't really have an answer. He suggested that perhaps I should <br>
buy a less expensive drive, because the internals would be the same. He said Sony made some pretty <br>
good drives, they just didn't have the aluminum case, etc. that the Apple drive has, but would be <br>
half or less the cost. It would be great to have a Consumer Reports "mean time to failure under <br>
continuous burning" and whether there are any drives with different, more durable, internals.<br>
