The weird thing was that it would intermittently work. I have never had this problem with previous versions of FreeBSD, it must be a new 'feature' in 4.0. I just tried the -b 128 option and it did work so I have included it in the backup script and will watch it over the next couple of days. Thanks Rob. -----Original Message----- From: Colin Campbell [mailto:sgcccdc@citec.qld.gov.au] Sent: Wednesday, 6 September 2000 8:37 To: Rob Secombe Subject: Re: Wierd tape drive behaviour Hi, My first guess is that you need to write blocks > 53527 bytes to the tape drive. Without seeing your "tar" command I can only guess that you need to add something like "-b 128" to the command.
