Oddities installing 2nd IDE drive

Post by Dean Carpent » Fri, 07 Apr 1995 04:00:00

Well, we just got a spanking brand new Procom Tech.
PR-IDE drive for the HP Vectra here running 1.2.3.
The drive specs out at 826cyl 48hds 63s/t for about
1280meg.  This is a plain Slackware 2.1 install.

The system took it fine, and fdisk /dev/hdb sees it nicely.

Disk /dev/hdb: 48 heads, 63 sectors, 826 cylinders
Units = cylinders of 3024 * 512 bytes

   Device Boot  Begin   Start     End  Blocks   Id  System
/dev/hdb1           1       1      34   51376+  83  Linux native
/dev/hdb2          35      35     826 1197504    5  Extended
/dev/hdb5          35      35      67   49864+  82  Linux swap
/dev/hdb6          68      68     420  533704+  83  Linux native
/dev/hdb7         421     421     515  143608+  83  Linux native
/dev/hdb8         516     516     826  470200+  83  Linux native

Originally, the system saw the drive as having 2497cyls, 16hds 63s/t
and fdisk seemed to like it OK.  I was a little worried about the
number of cyls, so in the BIOS setup I changed it to what's above,
which is what the drive really has according to the data sheet that
came with it.  It was close to 2497 at least, I don't remember exactly.

This will eventually be the only drive in the system, hence
the various filesystems, / /usr /var /var/spool/news in order
in this list.  The mke2fs seems to go OK on each one, a couple
of them giving this msg :

Checking for bad blocks (read-only test): Bad block 0 out of range; ignored.

The filesystems seem to work fine though.  The main problem is in
the "mkswap -c /dev/hdb5 49864".  With the mkswap from SW 2.1, it
gives this :

jedi:~# mkswap /dev/hdb5 49864
Setting up swapspace, size = 51056640 bytes
mkswap: unable to write signature page

I grabbed the latest mkswap from the a2/util.tgz in the sunsite
Slackware 2.2 distribution, but it gives the same thing ...

What's going on here ?



1. Linux on 2nd IDE drive on 2nd IDE controller?

I am considering installing Linux on my PC.  All of my hard drive space
is spoken for, so I would need to add a third hard drive to my system.
But, before I go out and spend a few hundred dollars on a new
hard drive, I was wondering if anyone could tell me what sort of problems
I might have if I set my PC up this way:

System is a Gw2k P5-120, 32 meg 60ns EDO ram, ATI Mach 64 graphics, on board
EIDE controller, Ensoniq Soundscape sound card.

EIDE Controller 0:
     Drive 0:  OS/2 Boot Manager
               FAT partition for Window$ '95 (*mutter* *grumble*)

     Drive 1:  5 HPFS partitions (OS/2 Warp, programs, data, news spool, etc.)

EIDE Controller 1:
     Drive 0:  ATAPI-compliant 3-disk CD-ROM drive

     Drive 1:  new HD, where Linux partitions will go

In other words, will Linux squawk at being installed on or booting from the
secondary drive on the secondary controller?  Or, do I need to look into
getting a SCSI drive?  I haven't seen anything written in the files I've
looked at that suggest that there might be a problem, but....

Also, is there anything special I need to know in shopping for a
hard drive for Linux, or about hardware problems I am going to encounter
(aside from only being able to use tray 0 of the CD-ROM drive....)?

Thanks in advance.
