Cannot Copy files from DVD data disk
 

I recently installed Mandriva Linux 2005LE and backed up my data on DVD + R. Before installing the system I checked the DVD backups to make sure my DVD drive would read them. It checked out o.k. Now when I try to copy the folders back on the HD using Konqueror
the copy process will begin and the stall . It will copy from 13 to 50 % of the data. I can read the files mounted in the DVD but no luck copying them to HD. The DVD drive is a Plextor PX-708A. I have had this happen with CD's before also.

I get the feeling that possibly there is an adjustment to be made somewhere in the software like a cache or something but I don't know where to do it.

I would welcome any ideas as to how to solve this problem. Thank you.

One thing you could try is temporarily disable DMA.

Press alt+f2 to bring up the run command dialog, and type kdesu konsole to bring up a root terminal.
In konsole, type hdparm -d /dev/dvd to check the dma status, hdparm -d0 /dev/dvd to turn dma off, and hdparm -d1 /dev/dvd to turn dma on.

Note that these changes are not permanent, they will be gone next time you reboot.

I followed your instructions as outlined in the previous message; however, after turning off dma , the problem still exists.

Thanks for your assistance.

Bear2x,

I am not sure what is causing your problem, but I know konqueror will stall sometimes when dealing with directories with a large number of files.

Some things to try:

1] Try copying fewer files / directories at a time.
2] Try doing the copying from the command line (this is probably the better option).

Hope this helps.

I followed your suggestion of copying fewer files at a time and this helps.

Thanks for your reply.
