Couple of other threads on this... if you put the Kingstons into the Mac you may have killed them permanently.

I have a couple that I put into the MRC and it showed up as already formatted.

I searched, but cannot find such threads.

I guess these are toast, then. I'll send them back.

Any recommended brand of 32GB CF card that I *can* format with the MRC1? At this point I'm willing to pay a premium just so I can get this working. Transcend?

I use the Transcend with no issues, "knock on wood".

However, after much reading I came to the conclusion to either not format the card at all and simply put in the MRC1K and run as usual, which I have done with three 32GB Transcend cards. Or, to format the card in the MRC1K only and not in your computer. The MRC1K manual even says this.

BTW, I am using the MRC1K with Sony FX1 cameras.

Thanks, Michael. I read the manual and these forums, so I tried formatting the card with the MRU first. That failed, which is why I tried my Mac.

Have you tried formatting the Transcend cards on the MRU? Thanks!

Chris sorry, as I said I have never formatted the Transcend cards.
And they have functioned fine with the MRC1K.

As for card reading, I simply use an external card reader, SanDisk I believe.

Ok, so it sounds like you might run into the same problem with the Transcend as I did with the Kingston. Guess the general rule here is to just never format these 32GB cards with the MRU or your computer unless you want to render them useless!

My mistake... the Mac killing cards issue was with Transcends. The Kingstons just suffered from bad batches and unreliability, as described in these threads:

and

Sorry to add to the FUD.

I think I'm giving up on the sporadic behavior of the 32GB cards and will just return these and get a bunch of 16GBs instead. I don't want to run the risk of someone else (other than me) accidentally formatting a card and thus rendering the card useless. If anyone has had good luck with a 32GB card (including formatting it on the MRU), I'd still love to hear about it.

I'll pay the price for my SanDisk Ultras IIIs and IVs. I've never been fond of Transcend anyhow, but I'm a little surprised by the reports of issues with the Kingstons. Aren't they supposed to be a top RAM manufacturer? Anyhow, I've never had an issue with a SanDisk product. I'm using the 32GB cards quite successfully.

Anyhow, I see a lot of people talking about Kingstons and Transcends and problems, and I haven't seen SanDisk mentioned in the same context, plus I've used SanDisk products before in other applications. Therefore, I was much more comfortable buying the SanDisk.

Must my $0.02. US.

Thanks,
Matt

Had the same problem
 

I recently picked up a used MRC1K through the classifieds here and got three Kingston 32GB 266x Ultimate cards to go with it. I recorded successfully on the first card and then went to format the card in the Sony unit. I had the same problem as others with the unit displayed "Format" forever without completing the task. Reinserting the card just gave me an error message. Format on the mac was NG and I was about to send the cards back to Kingston when I plugged the cards into my iMac running Parallels and fired up Windows xp. I don't believe the card and reader (Lexar FW) were recognized but when I put the card back into the MRC1K, it formatted fine and seems to be OK. I will be taking it out for a shoot this weekend and will report back.

Dunno, maybe a fluke or a workaround for the formatting problems......

After being steered into the direction of getting the Transcend card I got the 32g one which gave me no problems when put into my MRC. When it was full I formated it in the MRC after downloading all of the video and have had no problems with it.

I have since erased the video from that card after downloading it because of other threads stating this was the way to go, and still have not had any problems.

I now own a second 32g Transcend which has only been erased after downloads with no problems to report. So, I have nothing but good things to report on my 32g Transcend cards.

Ridata 32Mb Cards
 

Just received a "Black Friday" email from newegg.com and they have 32gb Ridata "lightning series" 233x Compact flash cards for $85.99 each plus free shipping.

Add my voice to those who have had issues with the Kingston 32 GBs. Four out of seven, tested on four different MRC1ks, showed up as DOA. One would not format (hanging on the same FORMAT forever issue described above) and three showed the A:12 error on the MRC (not fast enough). So back to Amazon they went today.

On the plus side, one retailer has a really good deal on the Sandisk Extreme III 32GB three-pack, $459, and then there's a $200 Sandisk rebate. After another 3% cashback from Bing, that works out to less than $82 per card to my door -- less than the Kingstons.

I have had no issues with the one Transcend card I use.

I've had no problems with any of my Sandisk Extreme III 30MB/s 32GB or 16GB CF cards (or SDHC cards).

Looking into getting a 32gig card. Any new info? Good/Bad/Indifferent?

What sort of recording time are you getting on the 32 gig cards?

The two 16 gig Kingston 266x are working fine - but I'd like to record double that time if possible without changing cards.
