I don't know what release of amanda the tapetype came from. Old versions were horribly slow on some tape drives as it wrote an end of file mark after every 32K of random data. This resulted in what was known as "shoe shining" where after writing the filemark, the tape stopped, backed up to resync with the start of the next file, and resumed writing. For each 32K block!! You can probably check the specs for your tape drive. and determine approximately how long it should take to run. Two complete tape writes are done. If it takes longer than say 3 or 4 times the time needed for one complete write, something may be amiss. Tapetype is a standalone program. You could get the source from a new distribution and compile it. OH wait, nevermind -- I seem to be saying that frequently! :(( You gave tapetype an estimate. The -e option came in after the bad old days. -- Jon H. LaBadie [EMAIL PROTECTED] JG Computing 4455 Province Line Road (609) 252-0159 Princeton, NJ 08540-4322 (609) 683-7220 (fax)
