Myers) Newsgroups: comp.unix.bsd.freebsd.misc Subject: Partition error: "no magic" Date: 23 May 1996 03:50:04 GMT Organization: PSI Public Usenet Link Lines: 39 Message-ID: <4o0n9c$han@usenet6.interramp.com> Reply-To: dcmyers@access.digex.net NNTP-Posting-Host: ip77.san-francisco3.ca.interramp.com X-Newsreader: knews 0.9.3 I've been playing with configuring a magneto-optical disk for a little while now, and everything appears to work, except that I get the following error whenever mounting a MO disk: root> mount /dev/od0a /optical od0: invalid primary partition table: no magic So far, this has produced no discernible data storage problems; it's just a bit disconcerting to have that message pop up. Is anything seriously wrong? Here are two disktab entries I've tried (both produce the error): mo230|230 Meg 3.5inch Magneto-Optical:\ :ty=removeable:dt=SCSI:rm#3600:\ :se#512:nt#64:ns#32:nc#216:sc#2048:su#444384:\ :pa#444384:oa#0:ba#4096:fa#0:ta=4.2BSD:\ :pc#444384:oc#0: xmo230|Experimental enlarged 230MB magneto-optical:\ :ty=removeable:dt=SCSI:rm#3600:\ :se#512:nt#64:ns#32:nc#217:sc#2048:su#446325:\ :pa#446325:oa#0:ba#4096:fa#0:ta=4.2BSD:\ :pc#446325:oc#0: The xmo230 entry is a bit larger than the mo230 entry (446325 vs. 444384), and seems to fit my Fujitsu M2512A better. (The smaller entry produces messages about the raw size not matching the slice size.) Any help would be appreciated. -David.
