I recently bought a Panasonic Lumix DMC-FZ50K camera, and followed it up with an order for RiDATA's 4GB SecureDigital Card Pro (150X speed SD card). When I received the memory card, I dropped it into the camera, and was greeted by an error when turning the camera on:
MEMORY CARD ERROR PLEASE CHECK THE CARD
So I plugged the card into the USB 2.0 SD reader that I also ordered. The card works fine in there. I downloaded the SD/SDHC official card formatter from sdcard.org. The formatter is even made by Panasonic, which speaks really well to the prospect of it formatting the card so that it's compatible with a Panasonic camera. No go. Same error, and this error doesn't let me access the menu, so I can't try to make the camera format the card.
Any idea how I can make this work? Returning it to NewEgg for a 15% restocking fee doesn't appeal to me, and trying to get RiData to reimburse me sounds like an uphill battle (especially since the DMC-FZ50 is new enough that it's not on their compatibility list for the card at http://www.ritekusa.com/ebproductdetail.asp?id=52 - however, the DMC-FZ30 is, and the FZ50 is a pretty minor upgrade to the FZ30).

The FZ50 specifically adds support for SDHC cards over the FZ30. As far as I can tell, the only difference between SD and SDHC is that SDHC is formatted with FAT32, allowing sizes larger than 2GB.
So ANY device that supports SDHC should support 4GB cards.

So far, I've only been able to play a little bit, because the only WORKING card I've got is the 32MB card that came with the camera - which will accommodate 5 JPG's or a single RAW image. So even though I've had it for over a week now, I haven't really used it much at all. I was hoping I'd be able to do that now, after receiving my 4GB card, but no such luck.
So far, no reply from RiDATA or Panasonic about this card, but that's no surprise.

...so what exactly IS an SDHC card, but an SD card formatted in FAT32 format (thus allowing sizes over 2GB)?
I haven't been able to find a whole lot of specific information, but from what I did find before making this purchase, it doesn't seem that there's any other difference between the two formats. That leads me to the assumption that cards with capacities above 2GB that weren't labeled as SDHC were basically just those cards that did it before the SD Association blessed it with the 2.0 standard.
To make matters worse, I've seen 4GB SD cards that don't say anything about SDHC, but do say that they support the 2.0 version of the spec - i.e. the version that adds support for higher capacities (that is, SDHC).
Simply put, I'm confused, and I'm out $70 unless I can find a solution or RiDATA buys the card back from me (or return it to NewEgg and take a 15% restocking fee hit; which I'll do before eating the $70 for a worthless card).

It really doesn't, unfortunately. It says that SD cards can be formatted in the 4-32GB range (i.e. higher address space because it's using FAT32 instead of FAT16), and that it's not backwards compatible with previous versions of SD (i.e. because devices designed for the FAT16 file system won't work with FAT32-formatted storage devices). It also goes into the new speed rating system, which is nice because most cards are currently only rated for their read speeds.
However, it doesn't tell me what the difference is between an SD card formatted with FAT32 that's not labeled as SDHC and a "proper" SDHC card, and work with NewEgg if they'll accommodate something to save me the 15% restocking fee. That is, how do the 2.0 and prior (1.1, was it?) versions of the SDA spec differ other than the FAT32 format (and the new way of rating speed; which has no bearing on compatibility, only performance).
I guess I'll just order a 2GB card until SDHC gets a bit more mature and I have a clear idea of what 4GB (or larger) cards DO work with the FZ50, given that another response from someone who had a 4GB card fail in the camera gives me little confidence in being able to order another brand and have it work. I'd like to primarily shoot RAW format, which is my main reason for wanting as much capacity as possible (less than 100 RAW pics fit on a 2GB card).

Well, I'm one of those people who figures that if something won't work, it won't work, and spending a lot of effort figuring out why it won't work is pretty pointless, other than as a mental excersize. The second paragraph is pretty specific: "Because SDHC works differently than standard SD cards, this new format is not backwards compatible with legacy SD format host devices." But, DPReview says the FZ50 is compatible with SDHC (http://www.dpreview.com/reviews/specs/Panasonic/panasonic_dmcfz50.asp), so it would seem evident that your problem with the RiData 150X 4GB card is that it's too big for the FZ50 as an SD card, and in order to be recognized, it needs to be an SDHC card. It doesn't matter what the differences betwen a 4GB SD card and a 4GB SDHC card are unless you can turn the card you have into a SDHC card. I can't seem to find a way to do this (probably because if anyone could do so, the makers would lose a munch of bunny). Sorry. :-( -- Bill Funk replace "g" with "a"

Some of us just like to know stuff. :) Aside from that, though, it could help in picking a replacement if I have a better idea of what's what. A few companies are labelling their larger SD cards with the SDHC label, but a number of them are just calling them SD. Some of those (like OCZ) have info buried on their website saying that the larger cards require a device compatible with the SDA 2.0 spec - i.e. the spec that adds SDHC support (and specifically-non-SDHC cards that use the new SDHC speed class ratings, like Panasonic's). So whether a card is _labeled_ SDHC or not seems to have little relationship to whether or not the card follows the SDHC spec. (Perhaps done for continuity of manufacturing? Perhaps there are additional costs associated with licensing the new logo or getting their cards tested for the new speed classses?). I want to know what's what, and it seems that the question that comes before "which ones are really SDHC?" is "is there even a difference aside from file system format?"
Bottom line - I want to know what I can use in my camera. I tried a 4GB card that appeared to be compatible, and it doesn't work. Another person who replied said he has the same problem with a 4GB "SDHC" card, suggesting that he had a card labeled as such, and it didn't work either - and suggesting that there's more to compatibility with this camera than just SDHC vs non-SDHC (or that he was mistaken on what kind of card he had). The camera's manual specifically mentions 4GB cards, and Panasonic even sells an SDHC card that's listed as an accessory in the camera's manual (Panasonic's cards cost 2-4 times as much as anyone else's, for only a Class 2 rating, so that's not an option)
>The second paragraph is pretty specific: >"Because SDHC works differently than standard SD cards, this new >format is not backwards compatible with legacy SD format host >devices."
That's pretty darn vague, actually. FAT32 vs. FAT16 could be "works differently." Or there could be more substantive differences.

Those SD cards labeled only SD aren't SDHC, obviously. They won't work in cameras, evidently. But cameras aren't the only devices that use SD cards, so non-SDHC cards may well still have a market. For your camera, buy those cards labeled SDHC.

What others tell as anecdotal information may not be worth much. You haven't tried a SDHC card, so you don't know it won't work. You do know a 4BG card not labeled SDHC won't work, though, pretty much as advertised. If I were you, I'd get a SDHC card, and try it. If it doesn't work, *THEN* I'd have something to complain about.

You didn't read that right; they aren't talking about FAT16 vs FAT32, they are talking about SD vs SDHC. Very specific.

I'd love to follow up on this, but now I've gone through two cards - one was a 4DG non-SDHC SD card, which the FZ50 doesn't support. It only works with SD cards 2GB and smaller. So I bought a 2GB Patriot 133X SD card, being unable to find an SDHC card in stock anywhere on short notice (I wanted to be able to use the camera at a party this weekend). I got the card on Thursday, and assumed all was well because the camera didn't choke when I put the card in and turned it on (and had no trouble formatting the card).
Unfortunately, it can't actually WRITE to the card. When I take a picture, it tries to write for awhile, and chokes. The card works (in my USB reader), and the camera works (with the included 32MB card, which is small enough to be useless for anything beyond verifying the camera works). But apparently there's a great deal of "leeway" in the compatibility with various different SD cards.
My only viable solution at this point appears to be going to a Big Box Store and buying a card, trying it out before leaving the parking lot, and returning it if it doesn't work (again). I'll spend more for a 1GB card than I'd spend on-line for a 2GB card, but at this rate, I'll be spending all of that money on shipping back and forth to find a damn card that works with this camera!
So I guess I'll stick with whatever card I find WORKS for the time being, and revisit the SDHC scene in a few months, when the standard has been around for a bit longer, and there are more cards available on the market (NewEgg and ZipZoomFly each sell only one--the same one--and it's often out of stock).
On that note, has anyone tried the A-Data card listed at NewEgg (URL below) in the FZ50? If it's known to work, I'll order it.

Did you buy the OCZ card? OCZ's website claims that their 4GB cards require a device that supports the 2.0 spec (SDHC), but reviewers on NewEgg claim that the card isn't actually an SDHC card, but is another 4G SD (non-HC) card.
If not, what card did you buy?
>sent it back to the place I bought it for 4 1 gig cards in trade -- they >said they would do that on the phone
You sure you got it "from same place" (NewEgg)? I asked about an exchange, and was told that they don't do exchanges for different products, at all. Instead, they offered me a refund, and at least according to the email they sent me, they're not charging a restocking fee (I don't know why, but I appreciate it. I hope ZipZoomFly is as kind when I return this 2GB Patriot card).

That isn't specific at all. It says that the two formats work differently, but doesn't say HOW they work differently. Different file systems would be a way of "working differently."
For those who ARE interested, I found a few sites that actually specify how the two formats are different. They use a different memory addressing scheme, going from byte addressing to sector addressing. Different memory addressing methods would definitely explain the complete lack of compatibility between devices that don't explicitly support the new format.

Manufacturers often "undersell" their device capabilities for various reasons, so the fact that support for something isn't _listed_ doesn't necessarily mean it doesn't work (especially common in DVD players that support VCD, SVCD, PAL, etc without specifying anywhere).
Panasonic doesn't explicitly list 8GB or larger SDHC cards - has anyone dropped the money on one of the few 8GB cards out there to determine if they work (I'm not even sure who sells them, but I've seen release announcements)?

Oops - forgot the main point of my reply. :) What brands/speeds of 2GB SD cards have you used with the DMC-FZ50? As I indicated in another reply, the Patriot card I bought from ZipZoomFly doesn't work either. The camera reads to it, but can't actually write images to it.
