Say, that's not a bad idea. I was going to order in IDE converter
anyway. Why not order two?

Hi Peter,
My first thought is 'salvage'.
If you're in Toronto near the west end, you could try A1 Electronics.
www.a1parts.com. It's an industrial unit full of junk. I'm thinking
you should be able to score a dead motherboard or SATA controller for
$5 and remove the connector you need.
Another option might be to check the service department at your
neighbourhood computer store and try to get your hands on a dud
motherboard or controller there.
The best way might be just to order a cheap component that has the
connector you want and canibalize it. Here's one example:
http://www.dealextreme.com/details.dx/sku.706 DealExtreme is all
kinds of fun. All their prices are in USD and include shipping. It
takes a few weeks to receive your order because it's shipped from Hong
Kong.
Good luck,
Dave

Thanks, guys. This explains a lot. Too bad that SS drives were so
expensive at the time. I would have bought one of those instead. BTW, does
anyone know where to order a replacement SATA connector for a motherboard?

Ive build many a system with CF cards, they are very reliable(BSD based).
Just don't write to them! cf's will easily outlive anyone in a ro state.
There are some tips and tricks though you need to be aware of when using
ssd's (linux has some additional tweaks needed over *BSD)
In short though without writing a really lengthy email,
You'll want to optimize a base image of your desired os to be read only,
things like /var should be mounted as memory disks.
This will give your CF card (or other ssd) an indefinite mtb (75+ years if
your not writing to it). If you really want to bolster its performance on
small hardware create an operating system that runs entirley in ram (loaded
from a ro ssd on boot).
A really good example of well put together os/asterisk distribution is
askoiza. (http://www.askozia.com/)
Id recommend anyone interested in os/file layouts for ssd's do a quick
play about with the embedded version.

Philip Mullis

Would that explain why my CF card got corrupted and had to be
reformatted? I was running OpenBSD on it with the FFS file system and a
StarTech IDE adapter. Seems OK now but I'm not sure how reliable it is
without more testing. How do you find a reliable CF card?

I think it was Dave that was recommending the solid state disks.
When moving over to solid state, keep in mind that the consumer CF/SD
cards are not designed for environments where there are a lot of small
writes. The technology is improving rapidly as well, so the market is now
swimming in flash of varying degrees of durability with no clear
identification.
There are wear levelling algorithms built into the cards to help extend
the lifetime of the flash, but you'd be surprised how many writes there are
when using conventional filesystems! For instance, every time you access a
file, the atime (last access time) gets updated unless you disable it.
Another caveate is that the cell size is (I believe) 32kb, and requires
a full erase/write cycle to update any byte in that cell. You unfortunately
can not control this, as the memory storage mechanism is abstracted away in
the hardware and presented to you as a block device unless you are using an
MTD (you're likely not if ATA/IDE/USB adapters are involved).
This will all be moot in a year or so though, the newer solid state
disks support a stupid number of writes.

Hi all, thanks to a tip from Simon I'm looking at replacing HD with
Solid state drive SDHD in IBM thinkcentre PCs I would have to replace the
IDE drive for a new drive anyway, so the cost for the adaptor and memory
card (say 8/16 Mb) must be in the region of $85
My question is can I what combo would work well as there are many
adaptors (at Dealextreem) and lots of memory types.
