RE: [expert] external usb hard drive problems
In a nutshell run lsmod and look at all the modules that your USB drive is using. You'll notice that the interrelated modules are listed making things a bit easier for you. Then use mkinitrd and it's preload and fstab option to tell mkinitrd which modules to load into the boot image, and how they are mounted. Doing this gets everything loaded into ram during the boot and before any other services are started or called. -JMS |-Original Message- |From: [EMAIL PROTECTED] |[mailto:[EMAIL PROTECTED]] On Behalf Of |[EMAIL PROTECTED] |Sent: Saturday, October 20, 2001 11:34 PM |To: Jose M.

[expert] external usb hard drive problems
Hi, I have an external USB hard drive made by LaCie, which worked out of the box, was automatically detected during installation, and is set up with scsi emulation. If I boot with the drive turned on, it is accessible as sda1 sda5 (it is partitioned into 2 FAT32 partitions). There are errors when it first tries to mount, saying that the 2 devices do not exist, but then (I think because it only turns on scsi emulation AFTER trying to mount the drives) it tries a few seconds later in the boot sequence and is successful. My problem is as follows: if the drive is NOT turned on at boot time, I can NOT mount either of the partitions on the drive, getting an error message saying that the devices do not exist. The kernel modules for usb scsi emulation are loaded (and I even tried removing and reinserting the modules which I think are needed), but it just does not work. I think (and please tell me if I am wrong or omitting something) the modules that are used are usb-scsi usb-ohci and usb-storage (I think, am not at home and doing this from memory). The other question I have, although not as bad because it still works, is the error message I get when the system boots (that I mentioned at the beginning) where the mounting of the usb drive's partitions fails and then a few seconds later succeeds. Is this because the system tries to mount the scsi drives (sda1 sda5) BEFORE the usb-scsi emulation is loaded? I DO hope that someone can help me.
