Greetings -
A few days ago I purchased a Sony CRX195E1 (labeled as CRX195A1, but I think they're basically the same drive), which is a 40x12x48x Powerburn-enabled CD-RW. Although I have been able to get packet-writing to work in Linux, I haven't been able to get it to work in an entirely error-free manner. Examples are:
-If I delete a directory on the CD-RW (say, dir1) in Windows, I am unable to create a directory of that name in Linux (mkdir claims that a directory of that name already exists). -For some reason, at least one file (possibly more) gives me 'access denied' errors, despite the utter lack of restrictions put on the thing. For instance, if I were to do 'ls *.jpg' it would stick in the middle of the output 'myfile.jpg - Access Denied'. Furthering this problem, after deleting and replacing this file in Windows, I not only did not regain access, but I got TWO of these errors on the SAME filename. -The CD-RW's drive light is almost ALWAYS on when I have the CD-RW mounted. -On one disc, the drive writing time was exceedingly slow when writing lots of little files. However, I suspect that the disc may have been bad.
If your not using the patch I posted to the list friday-ish (or whatever day it was), every file create causes a read which really kills performance on a CDRW.
latest version of the packet-writing patch. In Windows, I'm using B's Clip 3.24 (which was what came with the drive).
Is anything showing up in the kernel log? (run dmesg to check). I've never used B's Clip 3.2 so I don't know what its doing when it deletes a file. You could try recreating the problem with as small a sample set as possible, pull only the used data off the disc, compress it, and send it too me and I can take a look and see if I can figure out what's going wrong. You could also run the UDF verifier on the disc and see what it has to say. Ben
