Before all this started to happen I had 4 optical drives in the tower. Top to bottom, SH-S203b, PIONEER DVD-RW DVR-215D, HL-DT-ST DVDRAM GSA-H62N SCSI CdRom Device and ATAPI iHAS120 6 SCSI CdRom Device. The server had 3 optical drives in it, one of which, HL-DT-ST DVDRAM GH22NS50 was the first to go. The next 2 to go in short order were SH-S203Bs, neither of which will now read or write. The server is now back up to 3 drives, all working properly. My situation is HL-DT-ST DVDRAM GH22NS50 (will read not write,) PIONEER DVD-RW DVR-215D, HL-DT-ST DVDRAM GSA-H62N SCSI CdRom Device and ATAPI iHAS120 6 SCSI CdRom Device, apart from the LG all working fine except for the fact that the LiteON is the only one that can book type DVD+R Media to DVD-ROM. At the start the Samsung and the Pioneer were on the 2 Marvell ports after Windows 10 rejected my Promise Card (which would have given me 2 extra SATA ports and 2 PATA ports on one cable,) LG and LiteON on 2 of the others on the board. You can probaly tell I was trying to avoid using the Marvell, had problems before with Marvell. Anyway, the LG went down from the server and the 2 Samsungs went down from mine, with all the other drives still working.
I forgot to mention that the drives get to about 40 to 50% of the write and then just hang.
