Oh, well. I'm figuring this out little by little, but its comin' along. The info in the startup screen doesn't seem to help much to figure out how to designate the drive. Here is the part from running dmesg: fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa fdc0: FIFO enabled, 8 bytes threshold fd0: 1.44MB 3.5in wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): <FUJITSU M1636TAU> wd0: 1225MB (2509920 sectors), 2490 cyls, 16 heads, 63 S/T, 512 B/S wdc0: unit 1 (wd1): <FUJITSU MPC3032AT> wd1: 3098MB (6346368 sectors), 6296 cyls, 16 heads, 63 S/T, 512 B/S wdc1 at 0x170-0x177 irq 15 on isa wdc1: unit 1 (wd3): <ST32122A> wd3: 2014MB (4124736 sectors), 4092 cyls, 16 heads, 63 S/T, 512 B/S wdc1: unit 0 (atapi): <CD-ROM CDU55E/1.0u>, removable, accel, dma, iordy acd0: drive speed 344KB/sec, 256KB cache acd0: supported read types: CD-DA acd0: Audio: play, 256 volume levels acd0: Mechanism: ejectable tray acd0: Medium: no/blank disc inside, unlocked scd0 not found at 0x230 > > You mention that it is not a good idea to not mount disks down the > > directory tree, such as /mnt/whatever, but rather to just mount it > > to a directory on the top level.

Yours is on /usr, and it's accessed via a symlink. I took your suggestion here also, made a directory at the top of the tree, /2nddrive and /windrive. I probably don't need two separate directorys for these but it just seemed logical to have one for each drive. Someday I may have both mounted at the same time, for whatever reason. At least now I can easily move my data files off the winblows drive to the fbsd drive, and reuse the winblows drive as a bsd drive. > > Greg > -- > When replying to this message, please copy the original recipients. > For more information, see http://www.lemis.com/questions.html > Finger grog@lemis.com for PGP public key > See complete headers for address and phone numbers Chip To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
