Lots of them succeeded transporting 32 kiB of data per call. Now one of them suddenly failed with no error message from the drive's firmware. > May 22 09:00:51 penguin kernel: [45975.237515] usb 2-9: reset high-speed USB > device number 3 using xhci_hcd > May 22 09:00:52 penguin kernel: [45976.212240] sr 7:0:0:0: Power-on or > device reset occurred This is probably the reason for above error reply. The USB connection went away and the file descriptor became invalid while it was waiting for the outcome of the pending SCSI transaction. Hard to say what makes the involved controllers mad after a while of burning. The rotation speed might grow and thus consume more power. But you had effective CD speed 4, which is rather moderate. Did you already try to plug it into a different USB port of the computer ? Does it have its own power supply (or does it have two USB cables) ? > DV-W5000U CD/DVD Premium reputation but probably as old as the first cdrskin release. :)) Photos look like it's a full height drive in a USB box. Those quite surely have internal SATA or IDE controllers connected to a USB bridge in the box. One can buy 5.25 inch USB enclosures with SATA-USB at about the price of a new Blu-ray burner. IDE-USB might be a matter of virtual yard sales. So before you throw your TEAC away it might be worth to cautiously crack its enclosure and to look whether there is a SATA or IDE cable to see and the drive can be unscrewed from the box. If so, then it is up to you whether you invest in a new USB box at the risk that it is the drive's controller which goes mad. In this sad case, you could then buy a DVD burner for the box (again, IDE is rare now). It is hard to find expensive ones, nowadays. Have a nice day :) Thomas
