MxR adaptor problems for EX1

Thanks for everyones’ rapid responses! Tom

Ok OK I’m told off once again but I was being provocative. Even so I always try and use combinations of kit as manufacturers intend and they must have intended us to use the S x S cards. How come there’s been so many queries from other card users and very very few from users of Sx S ?

[Michael Slowe] “How come there’s been so many queries from other card users and very very few from users of Sx S ? “
Because people don’t do research and don’t buy cards with recent tested track records.
Sony’s own EX1 Hard Drive also does not overcrank very well.BTW there have been queries from SxS users with corrupted data. One common them seems to be that data from SDHC cards, which are non proprietary, seem to be EASIER to rescue with repair utilities than SxS cards.
Proprietary media is on the decline IMHO as SDHC and Compact Flash improve.
The great thing about SDHC is that I can handle this with any computer with a card reader I can pick up in any office supply store. That makes offsite backup very easy. On the other hand if you don’t have Sony’s own PCIe reader or laptop with Express Port and/or if either of those go “wonky” on you. There’s no way to grab a replacement.
Sandisk Extreme cards are readily available if you need just one more during a shoot.
Basically proprietary media is generally a more catastrophic point of failure.
You didn’t see all the posts when Sony didn’t have their SxS drivers ready for OS 10.6? . . . for MONTHS. Needing a driver is another point of failure.
People using SDHC cards had no such problem.

Absolutely Craig….
Also, in relation to corrupt media with SanDisk and Transcend, not all customers are divulging their workflow of their adapter and memory card. We had 1 case where the customer had returned a SanDisk 16GB class 4 not working and when I did a test check on it, this memory card contained jpeg files, tif files, gif files and had been used on Canon 450 DSLR…so in order for me to get this memory card working again, I had to reformat it a few times on a PC afterwhich I could use it again on the EX1 without any issues, whereas previously the same memory card would show up “media error”. There are a lot of customers who managed to buy very cheap Transcend and SanDisk, even from reputable companies which were fake, believing that they were original which obviously will cause huge problems because the firmware is really flakey.
2 reasons for media errors…
1. the memory card’s firmware failure; and
2. internal components on the memory card not being durable enough.
So far, I have done 4,503 hours of recording on EX1 with various memory cards without a single card failure. It is not a question of winning an argument or telling one off..An interesting note, in late June ’09, Sony headquarters in Japan purchased MxM with SanDisk and USB adapter. At the time I thought “oh yeah, they will do something with the new model… as in disable it” as it turned out, they improved it as mentioned earlier.MxM Express

I always stay out of these conversations. But I read them.

At the time I thought “oh yeah, they will do something with the new model… as in disable it” as it turned out, they improved it as mentioned earlier. “I think the above info is critical to understanding “Sony think” on the subject (as inferred by me).
Sony had mention many months before the EX1 was released that they’d support “inexpensive” media. I heard this FIRST HAND from Sony.Why I think Sony’s position changed. Sony found they could not exercise quality control over the SDHC card manufacturers as well as such other issues as counterfeit cards. With that and the potential support issues the only sensible solution for them as a business was to “not officially support” it. That is not the same as saying it can’t work or is unreliable. They used the very same technology for their external hard drive recorder, which they exercised control over. They did leave the door open to third parties (MXM for example) to undertake that.
Sony has no financial interest or motive in disabling that use given the market place. SXS cards, by their nature, would never be a big profit area for Sony. The typical user buys a couple of cards for the LIFETIME of the camera and would export and reload. It had NO POTENTIAL for mass use.
The EX series of cameras are probably dependent on MASS sales (much more so than the higher end cameras coming out of the “Pro” plant). Given that other camera manufacturers producing cameras in the same price class (JVC, Panasonic) using solid state, support SDHC, Sony was at risk of loosing significant sales to them because of the high cost of ownership of EX cameras (the SXS cards) and difficult end user maintenance (SXS drivers, express slot laptops, buying Sony SXS readers). Sony would rather lose the already small margins on SxS sales in order to sell MANY MORE EX cameras.
Hence the position that Sony took, IMPROVE support for SDHC but continue to hold the “not officially supported” position due to inability to control QC of the card manufacturers (who may aim for the much bigger photographer’s market).
Of course as more video cameras move to SDHC and sales of such cameras increase, the SDHC card manufactures start to have an incentive to improve their higher class cards.
In my very personal opinion, other than the speed of copy from SXS, SDHC beats it every other way . . . as long as third parties like MXM test and inform us (as they do). And now with the improved USB support in the EX1R there’s not longer even an overcrank limitation.

I’ve had a similar problem that I’ve suspected to be heat as well.
I’m using a Hoodman Raw adapter with Delkin Class 6 SDHC 16gig cards. I’m also using a Swit90 battery. After shooting for a full 3 hours of hand-held in 1080HQ 24p. Usually it’s towards the end of a full card I’ll get a ‘media restore’ error. If i shut the camera off, switch the adapter to a different slot, restore the media and keep recording, it solves the problem, even on the same card. But sure enough even if i switch cards and switch slots after the error, if my camera is hot enough, I’ll get another media restore error. I strongly suspect the heat is an issue. When I pull the adapter out of the camera it’s really hot to the touch.
Any ideas or suggestions would be most helpful. For now I’ll try to switch slots between cards to give one a rest, or perhaps shoot with the door open?
Thanks,

Yesterday I recorded with the MxR adapter with a Hoodman SDHC 16gig card, after ten minutes I got a Media Restore message. I transferred the media to my mac, accept the last take. When insert the card back into the EX1, it was not recognised anymore… (Unknown Media (B) Please Change
This error appears after shooting one 8 gig SxS card, camera was on for about one hour.
I ordered it as a Hoodman kit, Express Card Reader, SDHC card and SDHC to USB adapter, but the Express Card Reader turned out to be the MxR. Don’t know if that could cause the problem?Any ideas?

I have given up on figuring out what is at fault with these.
I started using Extreme HCSD cards and have not had a problem yet
with these… so I am thinking that it is a camera flaw.
I strongly suspect that the camera gets hot and the temperature
effects the write speed… and or corrupts files its writing.EMA VIDEO
