SCSI Woes (Not a Happy New Year)

OK. It's my own fault. But perhaps somebody can help me back on my
feet...

But how *do* you tell whether those brand new SCSI cables you bought to
hook your shiny new scanner to your system are going to corrupt your
hard disc on bootup, before it happens?


So,
1.  Can anyone recommend a UK source of really reliable SCSI cables, 1
to 1.5 metres long (as they are not normally advertised on the basis of
quality)?

2.  What's the best disc recovery software around for HFS/Sys 7.5.5?
Norton has shrugged its shoulders and walked away, apart from revealing
it has a corrupted name.


Looks like I'll be ordering a copy of Retrospect and a tape drive before
I try the next lot of cables

Incidentally, I observe that my new UMAX scanner's own SCSI cable has a
moulded-on ferrite core. These cores are designed to attenuate
undesireable RF energy escaping from a device. Now, what happens to its
EMC compliance if the scanner is used without this core? If the scanner
is generating RFI out of one port, what happens to its compliance if it
is placed in the middle of a SCSI chain and a further cable is attached
to the other port?


Cheers,
Francis K.

I've had kit from Trams before now; they seem to be a reliable dealer in
general, they have a proper workshop and they will talk through problems
with you if you ask nicely. They are in London, in Vauxhall, on 0171 544
1222. They do mail order.

Norton has recovered a totally trashed HD (HFS 7.5.1) for me in the past;
the HD wouldn't even mount initially. I got it onto the desk top only by
looking at it with Disk First Aid. However that version of DFA was pretty
useless. I then ran Norton. I had to have four goes at it. Each time it
fixed something further and then told me the disk was unrecoverable. The
fourth pass got right to the end. Finally I ran DFA again which told me
there was still a problem and fixed it. The disk is still running three
years later, so not too bad...

The version of Disk First Aid that ships with sys 8.1 (DFA 8.1) seems to be
much improved. It seems to work very well on HFS (and HFS+) HDs; it might
be worth seeing if anybody you know has a copy.

I've had great success with Disk First Aid on my Performa 475 running
7.1, 7.6, and 7.6.1. You might try the latest version (8.2, I think)
from Apple - it's not tested on anything before System 8.1 IIRC, and
will screw up if you ask it to repair the boot volume under System
7.6.1, but it is rather good - you have to put it on a floppy disc and
boot off that floppy if you want to repair your HDD.

(it is able to repair the boot volume if you're running 8.1)

But...  Different people have different experiences - DFA is excellent
on some Macs/OS combinations (I struck lucky), and not so good on
others.  A combination of DFA and NDD (run one, then the other) might do
the trick, but then again, it might not.  How about TechTool Pro?  It's
apparently dead good for hfs+; dunno about hfs.
