Message-ID: <5MAR91203419@uazhe0.physics.arizona.edu> Date: 6 Mar 91 02:34:19 GMT Reply-To: zazula@uazhe0.physics.arizona.edu Distribution: usa,local Organization: University of Arizona Physics Department Lines: 47 Nntp-Posting-Host: uazhe0.physics.arizona.edu News-Software: VAX/VMS VNEWS 1.3-4 Lines: 47 Can someone help me out here? I have a Micropolis 1578-15 drive. The manufacturer says that it is 382Meg unformatted, 338.1Meg formatted. When I boot my machine, it says MICROP 1578-15 313Meg. First I thought that the other 25Meg was either bad sectors and/or reserved by the file system. But, if I look at df, I get the following: kbytes used avail capacity 308891 226593 51408 82% Now it appears that 313Meg went down to 308.8Meg. But, add up used+avail=278Meg. This is getting worse. I'm missing 60Meg (or so it appears). Now, scsimodes tells me: scsimodes /dev/rsd0a SCSI information for /dev/rsd0a Drive type: MICROP 1578-15 512 bytes per sector 36 sectors per track 15 tracks per cylinder 1224 cylinder per volume (including spare cylinders) 1 spare sectors per track 45 alternate tracks per volume 639449 usable sectors on volume Doing the math: spare+alternate = 8.3Meg usable = 327.4Meg It dosen't seem like any of these numbers match up!!!! Anybody have any clues?? I'm willing to reformat to gain anything over 5-10Meg!
