yes it appeared to be more complicated. The HDD is scsi.
I found Adaptec scsi adapter, connected my traget HDD and booted another machine with puppy linux CD. The HDD was found at boot and there what I could see with dmesg :
# dmesg
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0
<Adaptec 2940 SCSI adapter>
aic7870: Single Channel A, SCSI Id=7, 16/253 SCBs

sda: unknown partition table
sd 0:0:0:0: Attached scsi disk sda
The disk was not listed on desktop for ones available to mount. I guess prelast message "sda: unknown partition table" was the reason. This was on my new linux box.
On the native machine during boot message pops up:
UHC UNIX System V Rel. 4.0 Version 3.6
then many messages about loaded modules
The uname -a returns:
fib1 4.0 3.6 i386 386/AT (fib1 - is user )
/etc/copyright - does not exist
With this original box flopies are formated at 1.44M and also I managed to make tar backups of some data. But my puppy linux could not mount them either.
Any ideas how to move on?

SD(4) Linux Programmer's Manual SD(4)
NAME
sd - Driver for SCSI Disk Drives
SYNOPSIS
#include <linux/hdreg.h> /* for HDIO_GETGEO */
#include <linux/fs.h> /* for BLKGETSIZE and BLKRRPART */
CONFIGURATION
The block device name has the following form: sdlp, where l is a letter denoting the physical drive, and p is a number denoting the parti-
tion on that physical drive. Often, the partition number, p, will be left off when the device corresponds to the whole drive.
SCSI disks have a major device number of 8, and a minor device number of the form (16 * drive_number) + partition_number, where drive_num-
ber is the number of the physical drive in order of detection, and partition_number is as follows:
partition 0 is the whole drive
partitions 1-4 are the DOS "primary" partitions
partitions 5-8 are the DOS "extended" (or "logical") partitions
For example, /dev/sda will have major 8, minor 0, and will refer to all of the first SCSI drive in the system; and /dev/sdb3 will have
major 8, minor 19, and will refer to the third DOS "primary" partition on the second SCSI drive in the system.
At this time, only block devices are provided. Raw devices have not yet been implemented.
DESCRIPTION
The following ioctls are provided:
HDIO_GETGEO
Returns the BIOS disk parameters in the following structure:
struct hd_geometry {
unsigned char heads;
unsigned char sectors;
unsigned short cylinders;
unsigned long start;
};
A pointer to this structure is passed as the ioctl(2) parameter.
The information returned in the parameter is the disk geometry of the drive as understood by DOS! This geometry is not the physical
geometry of the drive. It is used when constructing the drive's partition table, however, and is needed for convenient operation of
fdisk(1), efdisk(1), and lilo(1). If the geometry information is not available, zero will be returned for all of the parameters.
BLKGETSIZE
Returns the device size in sectors. The ioctl(2) parameter should be a pointer to a long.
BLKRRPART
Forces a reread of the SCSI disk partition tables. No parameter is needed.
The scsi(4) ioctl(2) operations are also supported. If the ioctl(2) parameter is required, and it is NULL, then ioctl(2) will fail
with the error EINVAL.
FILES
/dev/sd[a-h]: the whole device
/dev/sd[a-h][0-8]: individual block partitions
