Flash memory experiences? - General Accessories

My son's doing some research for his GCSE.
Does anyone have any expriences of flash memory cards (SD, CF, etc) being affected by X-ray machines or electromagnetic devices, such as are used at airports?
Or is anyone aware of any other ways in which the memory on a flash card can be damaged or erased (eg magnets?)
Any help gratefully appreciated....

Hi there,
As far as my experience there is no problem on airports with flash memory. My MDA II and the SD card have been multiple times in the X-ray scanner and no problem.

4GB SD cards for BlueAngel?

Hello,
I'm wondering if 4gb SD still works with our blue angel before i buy it?
I heard 2gb is working without any problem.
Thanks everyone!
Yes.
I'm using a 4GB SD card that I bought from Amazon.
thank you so much!
My Transcend 4GB card works like a charm. No tech problems whatsoever, and it's a little faster than my previous card as well (despite the speed limitations of the Blue Angel SD-reader).
But just so you know what you're getting into: as decadent as it may sound, I'm now facing a different kind of problem.
I've got about half of the card filled up with all the music I'll ever need, a TomTom map and the complete TLG (Thesaurus Linguae Graecae: every classical Greek text ever written, an invaluable research tool). Now the haunting question is, what will I do with the other half? 8)
No really, anybody got any tips? Are there any great programs out there that require a huge amount of storage space? I need to waste it on something cool or I'll explode!!! :shock:
:? I'm pretty sure this is exactly what Heidegger meant by succumbing to the inane obligations of new technological possibilities instead of using them as a means to an end... I wonder if a little "Gelassenheit" wouldn't be out of place here. So before you buy that huge sd card, ask yourself if you're ready to face the unfathomable existential void of about 2 gigs of leftover free storage!
Nah, just kidding, 4GB rules. Just buy it and don't worry about compatibility. Sorry about the rant. I've had too much coffee. :wink:
what about wikipedia?
or myFlash by www.adata.com.tw?

Now that might be a good idea.
A 1GB card would probably do me for everyday use, but I got a 4GB card to be used in my PDA and also as a USB drive by using it with card reader that is similar proportions to a USB drive - SanDisk MobileMate SD+ - fits on a keychain though I have to use an elastic band to stop the cap falling off. I need this so I can bring work home.
For everyday use I suppose I can fill it up with music so my PDA is more like an iPod. But I really need a large card when travelling - maps, scanned guide books and videos, music, podcasts to make the journey go quicker.
PDA as USB drive
Browsing through the forums, someone suggested using Card Export with a USB sync cable:
http://www.softick.com/pocket-pc/cardexport2/
to turn your PDA into a USB mass storage device - cool idea. Just downloaded a trial but transferring files is quite slow. Below is a quick test:
Card Export II with PPCTechs Lil' Sync Pro: 0.56MB/sec
SanDisk MobileMate SD+ Card Reader: 2.93MB/sec
It's probably because the "card reader" in the PDA is slow; I wonder if the BlueAngel supports USB 2.
Mini SD + Adapter + What to do with all the space
I've just (today) got a mini SD (2G) with SD Adapter.
The 1GB card was nearly full. (13Mb remains)
But the effect of the 2Gb... weird... or what?
Windoze XP Pro (SP2) declines to copy anything on to this SD + Adapter past the 1GB mark...
BUT...
BUT...
Microshaft's ActiveSync will??!!??
Mind you, it creates a funny looking directory list with loads of phantom file folders. But on the XDA, the files are all there, and beyond the 1Gb boundary, and they are accessible.
The card reader is one of those 50-in-1 usb jobs, with three extra USBs on the end.
Windoze File Explorer says .99Gb Used 913Mb left now.
I've yet to try this 2Gb + Adapter in my PCMCIA card adapter for my old Jornadas.
XDA now says 1019.46 in use with 913.63 free as well after copying my old 1Gb card and some 30Mb of docs I needed.
I hooked in here again to see if there was a simple fix for Windoze. Or indeed for our XDAs.
Even tried copying a folder full of txt, Doc, and PDF over to the card. When it failed on some nonsensical bad file error... which we know is wrong as the file is quite accessible on the PC where it was being copied from... we tried copying the remainder to another folder. It had a go at this and even put the copying screen with the files flying across... but they never went over and it soon failed on another error.
Getting back to your space problem... one of the things I use space on the XDA SD for now, aside from music mp3s, is audio books. I'd forgotten just how good it is to have someone read to you. Especially when it's someone like Tony Robinson reading Terry Pratchett.
Stick the XDA in top pocket, bins on, head back, and let the story take you.
We use a site which specifically caters for e-books and Audio now. I used to get them from the other more general download link sites, but this one is a bit specialised. It's called Wordhaven.
If you want a pointer to it, then please LMK.
After copying over an audio book I wanted to listen to (The Night of The Triffids, Unabridged 300 odd Meg) the XDA Settings/Memory/Storage Card reading became 1393.75 In Use, on 539.34 remains so I guess from one point of view... the XDA... it is working.
Files check out and play too.
It's just Windoze doesn't want to co-operate really with the file copying, but it still reads 1.36Gb on 539Mb remains in File Explorer.
Now why is that?
I was deliberately steered away from 4Gb for the XDA. After reading some of the accounts here I'm not too sorry we went for the 2Gb.
Does the fact that all cards we have seem to be formatted for FAT (presumably the ancient egyptian version) rather than FAT32, have anything to do with it... and why is NTFS not an option offered in Windoze format for cards??

SDHC

This is very interesting since there is a new SD standard out there called SDHC (Secure Digital High Capacity). From what I've been reading this standard support 4GB up to 32GB, and the old SD standard only supports up to 2GB.
What's more interesting the 4GB cards you guys are possibly referring to (?) are somewhere in between these two standards because it's too big for the regular SD standard but it's not SDHC. It's cool it still works though.
So is the 4GB card that you're talking about SDHC or "regular" SD?
They're regular SD cards not the HCSD ones, however technically since they exceed the 2GB capacity, they are no longer conforming to the SD specifications. I use the Kingmax M-Series ones without any issues.
has anyone used capacities of more than 4GB on their BA?
I have a big problem
I dont know how can I start ,, I will tell you
I bought sd card 4Gb from Ebay ,
after 3 weeks waiting came , after that I tried to fromat it from laptop, but its gave me only Less 1Gb after that I formated it from my blue angel, then gave me 4 Gb and work 100%

after 1 week I tried to make read it from my laptop the laptop make me format it again , and I format it ,,, but while its formatting the laptop became haaaaang :| .....
so ,, now its not working on my PCC and PC ,, when I tried to format it from the blue angle gave me , make me wait for 1 min then gave me this massege : " this storage card could not be formatted. try reinserting the card, or using a different one"

I have a 4gb SDHC card (Peak Xtreme x150 class6) and it does *not* work with my Orange SPV M2000 (Blue Angel).
So please don't waste your money and buy one of these cards (SDHC) if you're planning to use it with your PDA and nothing else.
(I hope this helps someone and maybe saves them some ca$h)

Two things might be happening here:
1. Your laptop might be an old one that can't read larger SD cards. Lots of older laptops won't read anything over a certain size (e.g. 1GB). When they can't read it, they often tell you that you need to reformat it, just like you saw. Some laptops have a driver update. If not, you can always buy a cheap USB SD card reader.
2. You may have bought a fake sized SD card from Ebay. There was a spate of them formatted to display a bigger size than they really were. Probably this isn't the problem, because you formatted it from your BA.
no one got some ideas for me?

HELP!! my 1gig storage card is maxed out at 512mb

morning/afternoon/evening to all my fellow ppc users....
i have a question that probly has a simple answer, but many hours of scouring the forums and google havent quite given me a concrete answer on this....
i recently bought a 1 gig micro sd with the adaptors for full size and mini sd (my phone uses the mini), and yet when it gets close to 512mb, it acts as tho its full.
the answers i have gotten on correcting this is to either reset my device fully again and start all over, or to attempt to reformat my sd card, which is the simpler, but i have heard that doing that sometimes makes it unreadable for ppc.
any suggestions or advice?
I've reformatted my cards lots of times and never had a problem. As long as you reformat it in FAT32 or FAT16 you shouldn't have a problem either.
One other possibility is that you have a 512MB card that's been marked/hacked to appear as a 1GB. This is a big problem on eBay as there are many sellers who do this.
i would hope not.... i bought this from a legit phone dealer and when placed in my comp it shows the space of a 1gig..... hopefully xeno's idea works.
Guys,
The bad news is that a lot of the Sandisk 1Gb MicroSD cards sold a few months ago on ebay were in fact 512Mb cards remarked as 1Gb !!! Quite a few unsuspecting dealers also got caught with stock - so your reputable dealer just may have been duped too...
First thing to try is to put the card into the SD adaptor.. Into a decent USB card reader on your PC. We use Paragon Disk Tools to actually fix / remove / repair the partition table on the memory card.. This is NOT fixed by simply formatting the card in Windows... Once your partition table is sorted, format the card as FAT16 or FAT32 (to suit).. Don't use Quick Format.
If this went well, your card is ready to go back into the PDA.. If the format hangs, then the card is either faulty or dodgey (!!)..
Good luck

Physically damaged MemoryCard

Hi!
I'm having a SD 2GB memorycard. There is a problem reading the card. When I'm using Windows disk management tool the card is not recognized at all but when using R-Linux (http://www.data-recovery-software.net/Linux_Recovery.shtml) the software knows there is a memorycard plugged in but can't see the size of it. It knows it's a SanDisk card but that's it.
I've tried reading the card with a couple of different cardreaders but with the same result. Connecting the card to Linux didn't make a difference either.
I know there are alot of bright people on this forum, so, any advice?
Is there maybe some special hardware to use and so on? Help would be great.
"EDIT"
The topic said "Physically damaged MemoryCard". The card casing is broken but the card itself is intact, I think.

Storage Card no longer recognised

I've have an XDA Stellar for 17 months, with the same Sandisk 8GB Micro SDHC storage card all along. Some months ago, it suddenly stopped recognising the card, but my PC could read the card fine. I couldn't face another hard reset, soft resets did nothing nor did blowing air from a can into the slot.
A month later, I changed batteries (which wasn't unusual; I have two official batteries for when I can't get to a charge), and suddenly the card was recognised although I had to reload most of my programmes, but at least I could access them and most of my files again. I was too superstitious to change batteries again although that made little sense to me.
Last week, the card 'disappeared' again and nothing (even a battery change) will fix it. The phone is nearly useless to me without all my programmes on that card. Does anyone have any suggestions for a solution? I've found nothing that works and it's driving me mad. Thank you for any possible help.
hi
first of all i am not a professional but what i would do in your case is:
put the storage card in another phone
sync with pc/save files in a folder in pc like sd backup
buy a new card and put it in your phone you are using now
copy the items in your new card
i dont know if it helps try at your own risk (there isnt much risk)
No Storage Card recognised now
Finalforce111, thank you for your response. But I forgot to add that I had tried other cards when this happened and it won't recognise any, not even eg the one that came with Copilot. So no storage cards are recognised, although they were before.
But thank you very much for your suggestion; it is much appreciated.
I would like to say that your Card Interface is somehow broken,i´ve your lucky,its just a cold soldering place..

[Q] Recovering Internal Memory from a broken phone

My phone got waterlogged at the beach, the removable microSD works fine right now so I have hope that I might possibly be able to recover the internal memory as well.
Basically since the phone's dead the only way I can get this data is if the Touch Pro 2 uses an microsd card for its internal memory so I can disassemble the phone and get to it. I'm not familiar with the internal workings so I was wondering if someone here can confirm or deny the existence of this.
