I am currently considering returning a recently-purchased Sony CRX175A and buying a Teac CD-524E. Among other reasons for the switch, I have had severe problems with using the Sony with pktcdvd; although I can read and write files to some extent, it sporadically fails and often leaves the discs unusable save for a reformat afterwards. Has anyone had any experiences, positive or negative, with the Teac CD-524E (CD-RW EIDE, 40x read, 24x record, 10x write), regarding Linux packet writing or in general? This seems to be the most attractive drive available, with support for Mt. Rainier pending a firmware upgrade.
My TEAC CD-512E is the only drive that I never made work with packet writing at all and it has some other problems as well. The chances are good that the problems are gone with new firmware (can't test without W*nd*ws) and new models like the CD-524E, but at least I won't get another TEAC drive.
Yamaha and Plextor worked fine for me.
^^^^^^ really, which model? I still couldn't get my Yamaha CRW2100S work with pktcdvd layer correctly. As I was describing on this list before, the MMC stuff works well from userspace, but if I try to go through pktcdvd layer, it have problems writing. The driver will even claim everything is OK, but during close of teh device, it will start filling log with errors. (I do have write caching disabled) Conf:2.4.16, actual pktcdvd patch, aic7xxx scsi card... BTW: Shouldn't the writing be a bit more polite to system memory? If I dd if=200MBfile of=/dev/pktcdvd0 bs=64k, it will immediatelly fetch the whole 200MB in the system memory(the cache will grow), the dd will report its stats and then hangs (I think in close) until it finishes/aborts the real write... But I think this is a general problem of the current block device layer, as I have similar problems when downloading from really fast ftp (7MB/s) to slow HDD.
