I "recovered" a 1TB USB drive that would no longer spin-up that way last
week, suspect a controller-board power-delivery issue, which apparently
the cold temperature helped, because it had done this before and once it
managed to spin-up it was good for months. But I'm not sure it would be
enough for a drive that can't read anymore.

Calibrate and Read, they're both like 1 or 2 (out of 100 or 199 or
whatever) - it can't read, spinning-up is fine. The drive shows-up in
Windows, so the interface to the computer works fine, but since it can't
read, Windows keeps freezing-up. It's still running in that old
computer, I just disabled it in the BIOS for now.

and can recommend?


How much are you willing to spend? Could be a few hundred dollars or a
couple thousand depending on whether advanced (expensive) software could
be used or they have to disassemble the drive in a clean room and use
special equipment to read the magnetic dipoles from the platters.


Max I'm paying is $500 Canadian. If they try to charge me $1500-$2000,
I'm doing it myself.

When my aunt found out it would cost $1500 to recover old data files
from her defective HDD, she decided that old data wasn't really worth
that much. Also, it is highly unlikely that they can recover 100% of
the data from the platters. With luck being against you, likely the
majority of the files you want to recover will be unrecoverable.


It's not damaged because I had a fire or because the heads crashed into
the platters and left nice circular traces into it. I suspect something
like one of the heads just doesn't work anymore, nothing more than that.
Recovery should be fairly simple. It was working fine on 100% of its
surface in the morning, couldn't calibrate when I came home from work. I
think it's just age - something failed, and it's not the spindle motor,
and I don't think it's the actuator/voice-coil that drives the heads,
since they still move back and forth.

nospam mentioned DriveSavers. They seem to be about what was estimated
to rescue data from my aunt's HDD and the company name sounds familiar.


Yeah, we'll see; that dude in your link paid them $1900, no way I'm
paying that. I have an exact same drive/model they can use for parts, if
they can't be reasonable I'm not playing.

https://www.geek.com/chips/drivesave...-drive-574764/


"Pricing is determined by the drive capacity, complexity and
completeness of the data recovery. The cost for recovering data from a
drive with severe media damage, like mine, is about $1900. An average
single drive data recovery costs about $1500."

https://acsdata.com/drivesavers-data-recovery/

That has ACS extolling DriveSavers, a competitor.


ACS has an interesting video of how to move platters from one drive to
another:
https://www.youtube.com/watch?v=GZx-tU1_gOw

Considering the how expensive it is to use physical recovery services, I
find regular scheduled backups (which eliminates user intervention since
humans are unreliable in saving backups at critical moments in change of
state to their drives) to other internal media (for fast restores) and a
2nd copy of offline media to be far cheaper and the shortest time to
recover.


Yeah, I'm more careful now (duplication and SnapRAID) but that computer
with the failed drive was old, and I kept reporting copying the files
over the network (slow) to later. Shoulda taken the time to do it lol.

Can you find a seller of the same type (IDE) of drive at the same
capacity (or a minimum size that would encompass the data files you
think are on the failed drive)? The rescue service provider might get
some of the data files off the failed drive but they may not be able to
put them back on the same type and size of drive you had. How accurate
is your measure of 15 years old for the failed drive? Up until
somewhere to the 80's, MFM was used. That got replaced by RLL by the
early 90's. Then came PATA and SATA (and some others). Since you
mentioned IDE, yours is using PATA which was called ATA or [E]IDE before
SATA came out.


It's not so old as to use MFM or RLL; it probably uses PRML. It's a PATA
drive, it does PATA-100 if I recall, interface-side - i.e. it uses the
80-wires cables. I don't really need another drive, once I have the data
the old computer goes to recycling. I'm keeping the computer now in case
I want to do recovery myself and need it to read back the drive.

Yeah, I will try that first if I decide the recovery labs practice
extortion.

You can hear head movement, but can you hear platter rotation? They
might perhaps just be stuck. (I had that, but in my case one at least of
the heads had stuck to the platter - I think; after all the recommended
things [freezing, shaking in various ways, ...] I finally bit the bullet
and opened up the drive in a clean cabinet at work: I could see the
heads weren't in the park position. When I attempted to turn the pack
[the spindle took the same Torx driver as the screws holding the case
shut - don't know if that's always the case], I felt something unstick,
and the heads then were free. Fortunately, after putting it all back
together, I was able to recover 95% or more of the data, so it must have
only been a tiny spot-weld somewhere. [I considered the drive junk after
that.] Obviously not stuck heads in your case if you can hear them
moving, but the platters might be stuck rotation-wise? Just a guess.)


It spins fine, no SMART issues there, but it can't read.

I'm also curious about how they recover drives if not by using
another of the same model (where they hell how they going to find
one as old as mine, and can they really keep one of each model of
ALL drives?) If you can enlighten me on that too, would be great.
Thank you.
Best Regards,


I would imagine there are "families" of drives, so they can use common
controllers - possibly using a master, versatile, controller. (I also
suspect that a _lot_ of the companies do little more than we do, other
than perhaps having "clean" facilities so they can open up to see if
faults like I had are the problem.)


Yeah, I read in a link someone posted in this thread, all they need is a
drive in the same family, not necessarily the exact same model. But will
they have such an old drive family around? I DO have another drive
anyway, they could use that. As far as what they do, they can do more
than we can (like Paul posted, they can address the drive via a serial
interface) but I don't think they have a programmable "master" drive
that can read any platter, any sector size, any track size, etc.

The problem with swapping PCBs (assuming you can find a replacement that
matches the old one) is the calibration and low-level bad-sector mapping
recorded by the factory during manufacture and testing won't match from
the replacement PCB to what is on the failed drive's PCB. Sectors
marked and masked out by the replacement drive's minicontroller will
prevent access to sectors for files you want to recover on the failed
drive, and you would end up trying to use the bad sectors no longer
mapped out to the minicontroller on the failed drive.

Nice info, didn't know about the calibration! Thanks!

You'll end up having to move the ROM chip, if still usabled, from the
failed drive's PCB to the identical replacement PCB. Easier and more
likely to succeed by repairing the failed drive's PCB, like replacing a
burnt TVS diode, than to replace the PCB and somehow transplant the
calibration and bad-sector tables to the replacement PCB.


The drive still spins and shows-up in Windows, so it's not a
power-delivery problem. I can swap the ROM chip, provided I am very very
patient with this (I don't have an air gun, so I'd be stuck with a
soldering iron.) If there was no possibility of a failed head then I'd
swap the boards right away...

Since the OP is asking about using a recovery lab on his failed drive, I
doubt he has the skills and gear to swap the ROM chip assuming he finds
a donor drive with EXACTLY the same PCB (same minicontroller, same
firmware) and even knows how to identify which is the ROM chip to move.


I have another drive of the same make and model, bought at the same
time. Identifying the chip might be a problem if there's a bunch of
similar chips on the board - the days where I could just look-up a chip
number in TTL books to see what it does are long gone.

There are lots of urban legends out there on swapping PCBs and magically
the replacement PCB on the failed drive suddenly works. The success
rate of a simple PCB swap is rare. Go to your nearest casino and you'll
have better odds of winning enough money to pay the recovery lab.


Well, I won't get nowhere if the problem is a failed head; then I'd have
to swap the head assembly and put the ROM chip back. It's all kinda
risky, those heads are very fragile, which is why I'm looking for a
cheap recovery place. But there's no way I'm paying $2000 just to get
old game ISOs and old documents - that drive has been in my old computer
for like 5 years with me not reading a single file from it (I used it as
a download slave, i.e. I downloaded on it and immediately copied the
stuff onto a USB drive. The data that was already there, I haven't
really touched in a long time.)

Hmm. If you have two identical drives, you can try temporarily swapping
the logic board. Sometimes, the board itself is the culprit and your
drives internals are actually okay; along with your data.


Yeah, if all I find are $2000 repair shops then that's what I'll do. Thanks,

I'd say it's probably worth - if you're considering this route - getting
the hot-air gun. My last 6 months' employment (with a company which
repaired car electronics; I was mostly on dashboards [the bit behind the
dials - it's a lot of the computing in modern cars]) involved a lot of
replacement of surface-mount devices; the devices (packages) themselves
are surprisingly robust, it's the tracks - and especially pads - on the
board that tend to lift. Especially where it's a pad connected to a
track that only goes under the device.

Since the OP is asking about using a recovery lab on his failed drive, I
doubt he has the skills and gear to swap the ROM chip assuming he finds

Yes, even reading the part number may require optical aid - and it's
highly likely to be a proprietary one anyway, though if you ask (e. g.
here) there's likely to be someone who recognises part of the number.

I wonder if a failed head could fail in such a way that it damages the
electronics to which it connects. I suspect open-circuit is more likely

incredibly stupid.


First of all, this is a 15 year old drive, things were bigger then
(bigger heads, bigger area for each bit on the platter, etc.) so it is
not as fragile as more recent drives (still pretty fragile however.) I
have opened and played around inside hard drives before, and did not
loose the drive. A clean room is nice, but not necessary if all I want
to do is read whatever I can ONCE from the drive.


a clean room is necessary, but it's the only copy of your data and if
you want to risk it, go right ahead.
