I have a wangtek 150mb tape drive running on SCO unix SYS V R2 and backed up my system prior to doing a low level of my disk. After formatting, I restore the system from tape and was on my way. In trying to restore a user filesystem, I ran into a tape error on the save tape. I have tried everything I know to get past the error to recover the rest of the tape, but to no avail. The wangtek drive just retries and retries, until I get an I/O error. So....., how can I recover this data? The tape was a 3M DC600A. I have tried several other tape drives, and they can not read the tape at all. I think the wangtek recorded the 120mb tape at 150mb density, which makes it unreadable by other drives. If you cannot tell me how to recover the data, is there a place where I can send the tape to have the data recovered? The 80mb of data on the tape represents 18 months of hard work on a C compiler, RTL, and assembler. Along with other "stuff". BTW, my other backups of the file system also have an error!!!! Any info would be welcome. Thanks, Jim Bevier jbev@jbsys.com

Get Henry Spencer's `tarx' posted recently to comp.sources.mumble. *Everybody* out there who ever uses tar should get a copy of it. It's nifty, and it's a good idea to have on hand before you need it. -- Chip Rosenthal 512-482-8260 | Unicom Systems Development | I saw Elvis in my wtmp file. <chip@chinacat.Unicom.COM> |

If you somehow manage to slightly corrupt a compressed tar file (it was something to do with a bad memory board, NFS, and a Silicon Graphics Power Server; don't ask), so that the header is no longer in the right place (and the file is not a multiple of the block size), tarx will be unable to find it. I want to fix my archive, so I will eventually hack up tarx to make it search for a string known to be in every header (such as my uid), but for now... -GAWollman Garrett A.
