I am hoping someone has come across this before. I have a script that transfers several gz files via Secure FTP across to an SFTP server on an NT machine.

The transfers show as successful:



gzip (Unix)
gzip: pack12_200812160337.tar.gz: invalid compressed data--crc error
gzip: pack12_200812160337.tar.gz: invalid compressed data--length error

I cannot figure out why only one of the files would be corrupted and all the others are ok.

I can also confirm that the file decompresses correctly prior to any transfer.

Any input greatly appreciated.

Not all tar/gzips are equal. Try upgrading your programs. I bet that fixes things.

Ok, thanks.

Not sure if anything has been changed but the problem seems to have gone away. Will monitor the situation and see what happens over the next few weeks.

You need to transfer zipped files in binary mode, not ascii mode.

Thanks, the transfer is Binary mode but still saw corruption on a single file.

The problem seems to have dissappeared, I am going to monitor it for now and fingers crossed I won't see the issue again.

if I find out what caused it then I will post here.

Thanks anyway

Just thought I would post the resolution to this:

Looks like we had a corrupt sector on one of the Drives on the SFTP server, replaced the drive and issued resolved.
