Subject: Problem extracting on Windows 2000 and XP

 

I am having problems extracting files from compressed tar (GNU tar) 1.12 archives created under Windows 2000 and XP. I do not see this problem on Windows 98 or Windows 98 SE. The commands are run from within a DOS .bat file. The archive creation/backup phase is as follows:

 

tar -cPvT %4 | gzip -c >%2.tz

tar -cMf %3%2.tzt %2.tz

 

Parameter descriptions are as follows:

 

%4 = command file containing list of files

%2 = archive filename

%3 = path of archive file

 

For example:

 

tar -cPvT archive.cmd | gzip -c >archive.tz

tar -cMf c:\temp\archive.tzt archive.tz

 

(archive.tz is a temporary file)

 

 

The archive extraction/restore phase is as follows:

 

tar -xMf %3%2.tzt

gzip -dc %2.tz | tar -xPvT %4

 

Parameters are the same as the backup phase.

 

For example:

 

tar -xMf c:\temp\archive.tzt

gzip -dc archive.tz | tar -xPvT archive.cmd

 

The backup phase works successfully. However, the restore phase fails under Windows 2000 and XP with the following error message:

 

tar: Archive.tz: Could not change access and modification times: Input or output  error (EIO)

tar: Error exit delayed from previous errors

 

I have narrowed the error down to the first step in the restore phase (tar -xMf %3%2.tzt). I have experimented with some of the file attribute related switches (e.g. –m) but have thus far not been able to correct the problem. Hence, I think this may be a bug. Could you please confirm this and let me know whether or not this has already been reported, or if a fix is available? I have attached copies of the tar and gzip executables I am using in case you require them.
