I doubt the data is compressed as well; the statement up front was that the disks contained compressed data. The 4k is a VTOC (Volume Table Of Contents); it is the old-SRV3 "disklabel" which was a non-optional result of the "format" command. Generally, we used the disks for tar archives; however, you should also check for cpio archives (more likely; without the extra package installed, SVR3 did not have tar, only cpio, especially on OPUS and Fortune systems boxes). Worst case, they are S51K file systems. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
