3 external drives daisy chained with FW800. One has files, the othe two
have backups. I used them for years with my old iMac. I bought the two adapters needed to use them with my new Mac Mini.

Nearly every day I start to get i/o erors. All three drives become
read-only. Time Machine can't complete backups. I can't copy files.
Finder error -50. Photos are sometimes corrupted when I try to view
them.

Power cycling the drives and the Mac brings it all back working. Even
the photos that had been corrupted are all OK. But then the problem
returns the next day or even sooner.

So I reconnected all three drives with USB. Problem has gone away, no
issues. What could explain the Firewire problem? Bad pair of
Thunderbolt-FW adapters? Should I try replacing them? USB 2.0 is slow,
I'd rather have FW back.

Hmm, do the drives have external powersupplies, or do they get the power
from the mac through the daisychain?
I think it could be a power problem.

Yep. I still have a FW-800 cable saved, but I gave up on FW drives quite
a number of years back (when 500GB drives were large instead of small
enough to be on my keychain if I had one).

Everything. My drives each have their own power. So FW bus power is not
the cause of my issue.

I will try reconnecting the drives with FW and see if the problem
returns. If so I will try to exchange the Thunderbolt adapters for
new ones. If the problem continues I will try to return them (I spent
$90 for the pair, it's not chump change) and move to USB.

OK, If you say so.

You might want to think about what happens if there is a wire carrying

carrying power in it is not quite working right. But you know best.

FireWire carries power. That is a fact. If a device is working properly
and the cable is working properly and the device doesn't need the power,
then everything is fine. If not, then the power on the cable can
definitely cause problems.

The more devices in the chain, the more lielkly this is to happen since
a down stream device may appear to need power, and that can affect the
other devices that suddenly have power on the cable they are not
expecting.

When everything is working, there's no problem, but power is a source of
many FW daisy chain weirdness when a device is not quite working right.

Never said different: but it is not 'always' passing power to devices if
those devices have their own source.

Never had any issues, but never had more that 2 devices in the chain

usb2 and fw400 speeds are similar. fw800 is faster, but not as much as
you might think.

new usb 3 enclosures are $20ish and a *lot* faster, leaving the drive
mechanism itself as the bottleneck.

a better option is buy a new drive that's has more capacity than both
of the older drives combined. 4 terabyte drives are around $100 or so,

Considering I recently bought a 4TB drive for less than $90, not spending

To be fair, it was a bare drive since I already had a case to put it in,

yes around there.

ebay, amazon and numerous other mail order sellers will ship to

i've bought *many* quality usb3 enclosures (not noname crap) on ebay

then buy two smaller drives, although it's not as good of a deal since
8tb-10tb is the current sweet spot.

there was a *very* good black friday deal for 14tb externals for
$170ish, but that deal is long gone now.

Sure but I need multiple drives, for file storage*and* backups.

How about a USB3/SATA docking station?

Those are getting rare. Voyager stopped making theirs and only makes a USB3 version now. I had to go to a weird site to find a replacement for the SATA version.

You are very very confused.

What happens if you "break the daisy chain", and connect the
drives one-at-a-time?
Will the connection stay stable?
Will it remain stable with only two drives connected?

It's been three days of one of the drives connected with FW, and so far
so good. I'll try connecting another and see what happens.

IIRC, FireWire always passes power, so this could be an issue.

=================== [1] <------

I used to have various drives and scanners on 400/800 FW that had
their own power supplies ... for good reason in most cases... (Nikon >>>> 9000ED scanner for example...)

What does that have to do with anything?

You implied [1] above that FW "always passes power". In a device with
its own power supply does not receive power from FW.

FireWire carries power. That is a fact. If a device is working properly

Never said different: but it is not 'always' passing power to devices if those devices have their own source.

When everything is working, there's no problem, but power is a source of many FW daisy chain weirdness when a device is not quite working right.

Never had any issues, but never had more that 2 devices in the chain
either. Both with their own power supplies.

I had two external Firewire drives daisychained from my 2009 iMac and
was using one to boot up into El Capitain, sometimes after a home power
outage they would not turn on unless I switched out the wires between
them. Recently after a big snow the power would go out momentarily
several times for a few hours, when I tried to turn the iMac on a while
later it was dead as a doornail. I tried everything even taking out the
RAM and putting it back in which someone on a Web forum suggested.
Finally I disconnected the Firewire cable from the computer and it
booted up as it should.

I'm dumping both of those Firewire drives and switching to SSD external drives, I already had one hooked up and had been booting up from it.
I've had it with that hassle. Plus there's no annoying noise with the
SSD drives.

Yup, made that switch a month ago when I got my M1 mini.
One SSD permanently connected for Timemachine, one connected once in a
while to make a ccc clone.
Fast - Silent - great :-)

I´m using these: <https://www.samsung.com/semiconductor/minisite/ssd/product/portable/t7/>

If somebody needs firewire cables: I´ve got a bunch I no longer need (FW
400 / FW 800).
Mail me if you can use them.

Looks like yours is faster than my ADATA SC680, I just ordered my second
one direct from the manufacturer on eBay: https://www.ebay.com/itm/ADATA-SC680-External-Solid-State-Drive-Black-240 GB/401955619516

On the plus side, it's only $32.99 and faster than the Firewire
externals I was using.
