I have a box with a Lite-on DVD±RW bruner on it. The drive has worded well for burning CDs and DVDs, as well as for reading. Several months ago I upgraded from Slackware 10.2 to Slackware 11, and it is using the 220.127.116.11 kernel.
The drive is hdb, and the ide-scsi transpation goes to /dev/sr0-> /dev/cdrom
DMA is turned on.
When reading and writing I get VERY VERY slow IO.
The drive being used worked just fine under the older OS install, so I’m trying to figure out what may have gone wrong. I just noticed this because I generally only burn DVDs seasonally, and I do backups on a different machine.
Can anyone point me to a checklist I can run through to verify everything, so that I can find what might be wrong and resolve it?
Oh, running hdparm -T, gets “read() hit ROF - device too small”
hdparm -i shows pio0-4, DMA mdma0-2, udma0-4, and that the drive conforms to ATA/ATAPI-5
