Slightly undersized CF cards with nanobsd images?
-
oh nice I should have caught that!
I guess these cards are all 3 cylinders short of 2GB.
New phrase has been coined: "he's a few cylinders short of a gig, if you know what I mean"

My $.02: The build sizes should be recomputed to accommodate these "few cylinders short" CF cards. Those should be the new standards. In the case of the 2GB cards, we're only talking about a 36-ish MB difference.

The problem then is a question of limbo: "how low do we go?"
Your card is a few cyls short, but are there many more out there that are smaller? Or will using your size suffice?
I wonder if anyone has a database of card sizes that is actually worthwhile in this regard.

I'm thinking the pfSense community can help. How about a new sticky thread: "Post Your CF card sizes" ?

Could it be that a 2GB card should have at least 2,000,000 bytes but may have more?
I don't know how the card size is used so this may not be a useful observation.

Oh man, maybe we need to treat 2GB like HD makers do:
2GB where 1GB is defined as 1,000,000,000 bytes…After all, the cards do use the proper SI for that, they say 2GB, not 2GiB.
Time to follow the standards :) -
Good day,
I was also having all sorts of issues with trying to write to a 512MB CF card using physdiskwrite under windows, but as soon as I popped a Linux LiveCD (Knoppix) I performed the write without issue.
Another issue, is that some lower cost CF cards are made using "chip rejects" that do not meet specs. Just like most HDD, they all contain bad sectors that gets re-allocated by its firmware. I believe all the extra sectors that would have been used for re-allocation are all used up hence the unusually smaller size.
Finally, a couple of cheap CF reader I had were also to blame for not able to read larger CF cards.

So what should the verdict be for those that have CF cards too small to fit the nanobsd images? I recently bought 2GB and 4GB cards and have no issues. But others no doubt would like to avoid purchasing new CF cards. I understand that pfSense is community supported and there really aren't a lot of resources to throw at this. I'm merely suggesting that the pfSense team needs to deliver a unified and unambiguous message to the users about this.
My personal feeling is that pfSense embedded is well worth the cost of new CF card(s).

Yeah, I totally agree, I would use only quality SanDisk CF cards.
However, in our local Fry's store, where no-name CF cards can be quite, well ALOT cheaper than even online, I buy several and perform a 10-pass destructive surface analysis, a read/seek/write test, check size, and return the ones or all of them that don't meet my expectations.

FWIW: I recently purchased 2 X 4GB Sandisk CF cards at Costco for $30.
In the early spring, I exhausted all of my local Radio Shack's supply of 2GB cards. These are the cards I've been using with recent snapshots and updates without incident.

Just note, all 5 of the SanDisk cards I have are the same size - too small, and they are from a "reputable" brand…so you can't trust much.

I don't think yours are faulty, they're just an older (and unfortunately smaller) generation.

You may have purchased "fake" SanDisk memory cards. They are mostly prevalent on auction sites and rarely on by major retailers.

Yes, even assuming 1 GB = 1,000,000,000 bytes is not enough for many cards.
gloomrider started this thread and posted that he has a 1GB card with only 998,129,664 bytes.

Actually, I was referring to the previous poster's CF card sizes. But using that card as an example, it could still be used with a 512MB image.
All of the 2GB and 4GB Sandisk cards I have bought recently work just fine with nanobsd. I'm thinking the developers are having similar experiences and downsizing images for undersized cards are not a big priority. But that's just speculation on my part.

Doubtful, they came with my Alix boxes from NetGate, so I suspect they are legit.

The sizes have been nudged down a tad, so keep an eye on the snapshots for new images:

Thanks!

Is it better to use 2 GB image with 2 GB cards? Since my 2 GB cards also couldn't fit the old 2 GB images, I've been using the 1 GB images forever.

That is really up to you. Some people believe they will use all the space, so they don't want to "waste" any, but also consider what databeestje wrote in this post:
