ubuntu - Tar unexpected EOF error on extraction. -

-

i have problem tar archive

i have tried solutions mentioned on other thread tar error: unexpected eof in archive issue has arrisen in different way.

history.

i got new laptop after old ubuntu laptop died. pulled out hdd , zipped old home directory.

after installing ubuntu on new system, copied on oldhome.tar.gz file.

i extracted few files individually, didn't need on old home untill recently.

i opened archive the default archive manager shipped ubuntu , whilst opening error message above.

the original home drive 30gb in size (before being zipped up). can 'unzip' archive , comes 1.2 gb, if use gzrecover utility can extract small number of original files , directories (using cpio).

here questions. there way can 'recover' original file had saved disk (remember able open , extract files previously), impression file considerably smaller was.

has been caused extraction of few individual files deep inside archive?

will there still 'footprint' of original archive on disk (much how deleting file tags sectors on disk allow them overwritten), if there util it?

i have lost semi important files didn't want loose thinking archive reasonable backup of them.

the archive made using default archiver om xubuntu 12.04 (64 bit).

the original home long gone, used external drive backup wifes pc before 'cleaning' out , re-installing windows her. drive has been 'formated' more once (remember access archive few weeks ago , extracted few files needed it).

thanks in advance advice.

david.
