Hello everyone. This is the first forum I’ve ever written to so please allow for indiscretions.
First of all, a big thankyou to all moderators and members for their information, experience and time, trying to solve our problems. I’ve learnt such a lot in a short time.
I purchased two 401Ss (ES0G) at the same time, one for me, one for my son. My main reason for this purchase was for storing digital photos, so RW was the way to go. Straight away, I tried the two disks (Ricoh) that came with the drive. Both appeared to burn ok. After several erases, the drive failed to recognise the RW. I tried a Philips(Ricoh)X4 RW with similar results. I’ve tried numerous X2.4 disks and they seem ok at the moment. All the written disks have played in my standalone player (Aiwa).
I then tried the two problem disks in my son’s drive and they were both recognised. They were written to and read back in his drive. My drive would still not recognise them.
My assumption is that my drive must have a calibration problem and not a firmware problem. These drives were purchased at the same time from the same shop so there must be numerous drives around with varying quality. There’s been a lot discussed on the forum about trying certain disks, but to my mind, it would be like searching for the holy grail if your drive is not top notch. Until Lite-On improve their tolerances then we will always have the problems discussed on this forum. Hope I’m not repeating anyone but I have not seen anybody with drives purchased as a pair.
