Not all 8x errors are caused by media. Some are caused by tape drives and some are caused by communication issues between the host and the tape drive. If the bulk of your errors were caused by a bad tape drive, why are you doing a long erase on your media? How do you really know it corrected anything at all? If the tape media wasn't the issue in the first place, it certainly won't fix anything. And if it did fix anything, you've got flaky media and it should be destroyed - doing more I/O on the media won't make things better. Media is CHEAP compared to the cost of data it's hosting. .../Ed -- Ed Wilts, Mounds View, MN, USA mailto:[EMAIL PROTECTED]
