[plug] Problems after hard drive swap around

[Greg Raftery]

Hello Pluggers,

I have strange messages on booting up my box after my weekend exercise in
swapping two drives around, and wonder if anyone knows what is going on. 

What I did was this : Original install was on /dev/hda. Put a second
installation on /dev/hdc, jumping into either at the LILO prompt, which
worked sweet. Slowly but surely configured the new installation to run how I
wanted it. Decided this weekend that I didn't need the old install anymore,
so swapped the drives around so that hda became hdc and vice versa. Fiddled
with /etc/fstab and reinstalled LILO and I can boot into the new install
just fine, except for the following strange messages when booting up
relating to a 'hdb' :

ide0: buggy RZ1000 interface: disabled read-ahead
hda: ST3660A, 520MB w/120kB Cache, CHS=528/32/63
hdb: non-IDE drive, CHS=723/13/51 **** THE FIRST WEIRD LINE
hdc: QUANTUM LP240A GM240A01X, 234MB w/256kB Cache, CHS=723/13/51
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15

Partition check:
 hda: hda1 hda2
 hdb:hdb: status error: status=0x00 { } **** AND THE REST ****
hdb: drive not ready for command
hdb: status error: status=0x00 { }
hdb: drive not ready for command
hdb: status error: status=0x00 { }
hdb: drive not ready for command
hdb: status error: status=0x00 { }

ide0: reset: success
hdb: status error: status=0x00 { }
hdb: drive not ready for command
hdb: status error: status=0x00 { }
hdb: drive not ready for command
hdb: status error: status=0x00 { }
hdb: drive not ready for command
hdb: status error: status=0x00 { }
hdb: drive not ready for command
ide0: reset: success
hdb: status error: status=0x00 { }
end_request: I/O error, dev 03:40, sector 0
hdb: drive not ready for command
 unable to read partition table
 hdc: hdc1

When I disconnect hdc and boot up the messages do not appear. The drive has
been repartitioned to a single partition and had a new filesystem created on
it. Apart from the messages about 'hdb', all seems well, as I can mount
/dev/hdc1. 

What is going on?

Thanks for any pointers (sorry about the length of the description)
