The default block size of tar is 20 * 512 bytes = 10240 bytes.
What do you get if you add the following option to your tar command:
b 2
I think of something like that:
tar -b 2 -cvf foo /foo

Ok, assuming you have no hardware problem:
- try that option -b 2
- at least for the first time I would avoid any hardware compression, although
I do not believe that this causes the trouble you mentioned
- if this doesn't help: Upgrade your kernel to 2.2.12. At least the
precompiled version 2.2.5-15 is not really a good kernel - in fact it provoked
several problems to some people and upgrading has helped
- In case you don't get further: I know from [EMAIL PROTECTED] that
that there have been applied several changes to the whole scsi layer and
that there have been some problems with some certain controllers; perhaps
you should have a look at that scsi list (e. g. via deja.com or altavista)
Bye, Juergen.
