There, I've summoned the courage to post it ;-) I have a Toshiba 1101 DVD-RAM drive attached to a Symbios 53C810a SCSI card. I have a cartridge formatted by Windows to FAT-16 with 64K clusters. It has never worked in 2.4-test (I got the drive on test-6) however it works perfectly using the 2.2 series kernels. The DVD-RAM drive is in two-LUN configuration: using single-LUN doesn't seem to make any odds. Before I trusted anything to the DVD-RAM drive I wanted to be sure it worked, so I copied 410MB of .RAR archives to the disk. At first I just got CRC errors and once a trashed FS on the cartridge (it was Ext-2 formatted at the time) , but since installing test-7 I get a kernel Oops when trying to decompress an archive on the cart (or even read it with less!) The test cart is currently formatted by Windows to FAT-16 with 64k clusters. I am not on the mailing list so if you could CC replies to me directly that would be great.
