defective harddrive data recovery

Hi,
one of my harddrives failed me recently taking the partition table into
oblivion. Hitachi is kind enough to offer replacement but before that I
want to recover what can be saved. I was able to recover a table with
testdrive that gave me partition 3 completely back making it possible to
copy all data to the replacement drive. However I still run into
problems with first and second partitons. First is irrelevant because it
was a softraid1 which has been replaced succesfully but No2 contained
approx. 30GB of mp3 copied from old vinyls. I have about 75% of them on
CDs but unsorted and without valid tags so recovery of the ones on the
drive would save me from several months work. Here is what I have done:

Disk /dev/hdc - CHS 15017 255 63 - 117796 MB
Check current partition structure
Partition Start End Size
1 P Linux ext2fs 0 1 1 1030 254 63 16562952
2 * Linux ext2fs 1032 0 1 7559 254 63 104872320
3 P Linux ext2fs 7560 0 1 15015 254 63 119780640

hdc3 is as I said mountable and files can easily be copied. hdc1 and
hdc2 however appear to be empty.

I found out that fdisk gives me different values by one sector:

fdisk:
Platte /dev/hdc: 123.5 GByte, 123522416640 Byte
255 K=F6pfe, 63 Sektoren/Spuren, 15017 Zylinder
Einheiten =3D Zylinder von 16065 * 512 =3D 8225280 Bytes

Ger=E4t boot. Anfang Ende Bl=F6cke Id Dateisystemtyp
/dev/hdc1 1 1031 8281476 83 Linux
/dev/hdc2 * 1033 7560 52436160 83 Linux
/dev/hdc3 7561 15016 59890320 83 Linux

(sorry, I hope you can figure out the translations...)

I assume that fdisk counts the first sector as No1 rather than No0. Is
that so? I get the testdrive values with yast and gpart as well.

Now, why is there a gap between hdc1 and hdc2, if I did not out it in the=
re?

As a comparison here are the values of the replacement drive which was
build up on the mirror partition hdb1 so the boundary values between
first and second partition should be the same but:

Testdrive:
Partition Start End Size
1 P Linux RAID 0 1 1 1030 254 63 16562952 [md0]
2 P Linux ext2fs 1031 0 1 7558 254 63 104872320
3 P Linux ext2fs 7559 0 1 14591 254 63 112985145

fdisk:
Ger=E4t boot. Anfang Ende Bl=F6cke Id Dateisystemtyp
/dev/hdb1 1 1031 8281476 fd Linux raid autodetect
/dev/hdb2 1032 7559 52436160 83 Linux
/dev/hdb3 7560 14592 56492572+ 83 Linux

The're not. Now I suspect that maybe all I have to do is move the start
of hdc2 down one sector and that might help. Is that so? Can I just do
that with fdisk (delete partition, create new one, no format)?

gpart is pretty useless here is what it gives me:
