Once upon a midnight dreary, Don Maslin had spoken clearly: Not into vaxen (yet) myself, but whilst I was searching the web, I found this page which seemed like it could be very helpful... http://www.s3.kth.se/~lha/VAX And I also found this: What follows is a list of hard disk data. The columns contain the following information: COMPANY maker of the hard disk NAME name of the model UNFO unformatted capacity in MByte FORM formatted capacity in MByte. Note that this may depend on sector size STPRTE average step rate or seek time in ms SZE size (5.25 inch, 3.5 inch or 2.5 inch) HGT height (FH or HH for 5.25, exact value for other sizes) INTRFACE interface. MFM and RLL go with a ST506-interface, SCS2 means SCSI-2 CYLINS number of cylinders (or total number of sectors) HDS number of data surfaces PRECMP precompensation IBMTYP typ for IBM AT and compatibles PWR typical power consumption BUFFER buffer size built into the drive in KByte AP Autopark function (T means Yes, N or F mean Not available) MADEUNTL year this drive was last manufactured Maxtor,XT2190,0,155,28,5.25,FH,,0,0,,0,0,,,, Which I found here: http://www.spock.mem.net/computer/text/harddisk.txt And there's also this one for lotsa drive specs: http://www.alaska.net/~zumwalt/Drive_Ide/Hdd_specs.txt I hope this helps you!
