OCF file system cards

Hi
where do i get smart cards which support OCF, here i am not pointing to java cards, i would like to know if there are smart cards(file system cards) which support java.
Regards
M.R.Rajaram

OCF supports cards that support ISO 7816. (Filesystem & JavaCards). Go to opencard.org and download. If you intend on using it on WIndows, go to Gemplus and get the OCF patch. Otherwise you'll get errors like 0x54 that don't exist !
You also might want to check out JPCSC. It will run on multiple platforms, and much better. Also it's open sourced and a bit supported.
Good luck

File system cards

Hi everybody
Noob question.Can I using Java Card Development Kit 2.2.1 with Integrated Circuit Memory Cards,which have no processor on the card and I think not JavaCard.
Thanks.

IS RAW DEVICES SUPPORTED OVER A CLUSTER FILE SYSTEM

Can raw partions be defined for datafiles after having choosen Cluster file system as storage option for database while creating fresh database using
DBCA?

> Do update on how the partitions have to be defined in either cases?
For both ASM and OCFS, a partition must exist on the disk - it can be of any partition type. Does not matter. Simply that the s/w references a partition and not an entire disk.
So for example, /dev/sdaf and dev/sdag are two shared devices on the cluster (LUNs on the SAN or whatever).
You create a partition on each. E.g
# fdisk -l /dev/sdaf
Disk /dev/sdaf: 36.5 GB, 36573020160 bytes
255 heads, 63 sectors/track, 4446 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdaf1 1 4446 35712463+ 83 LinuxTo use the first device as a OCFS device, you need to build an ocfs file system on it using mkfs.
And then it can be mounted as a "normal" cooked file system mount. Remember that /etc/fstab needs to be updated for mounting it on startup.
To use the second device for ASM, you have two choices. If you have the ASMlib kernel module installed, you can use that to configure a volume label and assign it for use by ASM.
Alternatively, you simply map the device (partition) to a raw device for detection by ASM. E.g.
# raw /dev/raw/raw1 /dev/sdag1Of course, you also need to make this permanent by updating the raw device list config file so that this mapping is performed on reboot. On Linux, this is the /etc/sysconfig/rawdevices file. Also remember that the user and group access for the logical raw device created, must allow ASM full access to it (e.g. use chmod oracle.dba /dev/raw/raw1).
In a nutshell, this is how to raw devices are used as ocfs and asm volumes. (on RHEL specifically, but I expect no major differences in this approach on other o/s's)

Java Card File System ...Please reply

Hi all ,
I am working on Java Card technology for last one year . Presently I am facing some problem regarding some file concept of java card .
I know that Java Card 2.1 does not support file system . But I want to simulate the file system in java card using applets . i.e . I want to write an application(applet) , which can simulate the EF , DF in smart card . Whenever APDU command is send to the file system applet , it should generate a Elementary file (EF) or dedicated file (DF) etc and store data to that file.
Can I do this type of thing using Java Card ? I am really in doubt .
If you have any idea on this , please let me know your view on this . If you know any open source code for this type of simulated Java card file system , please let me know .
I am desperately looking for a help .
regards
Dibyendu .
you can contact me to this email
[email protected]

dear duran ,
You have written that
"Follow the guidelines for the different supported filesystems on the JC"
But after Java Card version 2.0 , it does not support file system . I am using Java Card 2.1 .
Could please some sample code to my mail Id , so that I can take a look at it .
My mail id is : [email protected]
Please share the idea , as I am really need some help.
Regards ,

What company can retrieve photos from a micro sd card? Another casualty of SD Card blank or has unsupported file system

I have a Droid X with a sandisk 16gb micro sdhc class 4 installed. This card has been in use for about a year and wasnt even half full. I was playing music on thanksgiving and all of a sudden the music stopped. I thought hmm, It must be doing one of its many reboots. It wasnt shut off but was on my home screen and the music player had closed. I went to my music and the songs were still listed. I tried to play one and got the error message that i cannot play this file. I tried again and the songs disappeared and up came "SD Card blank or has unsupported file system" on the top bar. I tried to view files on the card on my phone and on my computer by using an sd adapter with no luck. I popped another card into my phone and it worked with no error message and i could mount and unmount the card and view the picture I took when viewing the new card on my computer. I have a 9 year old daughter who suffers from multiple chronic illnesses and have probably 200 photos on my card of her including an extensive surgery and recovery earlier this year. If a professional can retrieve my photos, I would like to know more. Im coming up on my contracts end and this has me ready to zip up a life vest and get on another boat altogether. I have seen hundreds post about this on boards but I hope this can be resolved. Thanks in advance.

Hi Matt73,
I use my phone to store all my precious moments too and I can just imagine how frustrating it must be to have memory card issues like the ones outlined in your post. I see that you have tried different things to retrieve your files from your memory card to no available. It appears that your SD memory card somehow became corrupted and most likely the data in it is now lost (sorry). While not a common issue, there is always a possibility for memory cards and any other memory device to fail. SanDisk Memory cards carry 5 year warranty, to get a replacement please contact SanDisk at 866-726-3475. Their hours of operation are 8:00 a.m. - 7:00 p.m. PT Monday to Friday or by email at [email protected] at your convenience.
I recommend backing up your media (specially pictures) on a regular basis to your computer or to an online service to protect those special memories, I personally have my phone setup to automatically save the pictures I take to my Google account and even if lost my phone I have a copy of all my pictures online. There are several website that allow you to sync your phone to upload pictures automatically. Please consider a similar option going forward.
On a personal note, I hope that your little girl's health improves that all those chronic illnesses are kept under control by your physician; I have 2 kids and I Know what is like when they don't feel well. Have a great day!

How to design a file system based on java card

I have reviewed all kinds of articles about it.And right now I can not find any source code to do that function.But how to design a full gsm file system using java card.
of course you need fast access,dynamic allocate memory,file properties management.Let's talk about it.

just do it.
there is no such feature in the javacard api. This must be coded by hand, you have to manage memory, etc.
I know, that's not cool.

Is OCFS(Oracle Cluster File System) a real file system?

Hi all
Is oracle cluster file system something kind of FAT23 or NTFS on Windows, ext3 on Linux ?
We install operating systems on FS , but with OCFS we install Oracle database on it instead of operation system ?
As usual
Applications
OS
File System
Physical Drive
But the ocfs is something like:
Oracle
OCFS
OS
OS's file system
Physical Drive
Is that right ?

Robert Geier wrote:
OCFS is a clustered filesystem. You don't use it for OS partitions (e.g /opt) but only for filesystems that will be shared between servers in a RAC cluster to hold database files.
Are you installing RAC ? If so, then ASM is a better option than OCFS. If not, then you really don't need OCFS.Thanks
I'm studying RAC.
I hear that I can not put all kind of files into ASM but with OCFS I can hold them.
Is that improved with 11g R2 ?

Camera connection kit - does it show file system on SD card?

Does the CCK show the entire file system on the SD card (like a card reader that you plug in a Mac or PC) or all the files at once (like Image Capture on the Mac)?
I need to see the entire file system so that I can easily back up what I want, for example the daily, weekly, or monthly folders that my camera creates, (depending on how I set it up), and keep the same folder structure and metadata. I already have a card reader that does that - ZoomIt - except that it is very slow. I am willing to give Apple's CCK a try, but only if it shows the entire file system on the SD card.
I read similar posts, but it is not clear (maybe it shows you the file system only if the root is named "DCIM"?). That would be less flexible than a standard card reader, but still serving my purpose.
Thanks in advance

In terms of albums they go into an 'Imported' album (which shows as 'Last Import' and 'All Imported'). In terms of Events you'll get one for each photo date from each import - so if you import photos shot on the same day from two different cards you'll get two date events, one for each card.
My compact camera shoots .MOV videos and it imports and plays them in the Photos app. Can't say for sure about AVIs, but the iPad spec page shows that AVI is supported.
If you want to check whether your AVI's are supported then you can use an app such as Simple Photo & Video Transfer (which is a free lite version of Simple Transfer) to upload one of your videos from your computer to the iPad and then see if it appears and plays in the Camera Roll/Saved Photos album in Photos.

Java card ISO 7816 file system

Hello
Java Card technology dose`t provide core APIs for ISO file system.Is there any mechanism for creating DF and EF on java cards.If there is,please guide me.Is there any sample code for this subject at sun.com?I want to creat DF and some EF on a java card and then manage them.How I can do it?Please guide me.

JavaCard doesn't contain a file system. It's been repeated in this forum over and over. How many times does this have to be answered ? Have you searched to forum prior to asking ?
For JavaCard there isn't a need for a filesystem because of the power of having a language on the card. Also byte arrays with a TagLengthVariable (TLV) do the job just fine.

Moving copy of project laptop to iMac. When I try to export my laptop project to either a thumbdrive or a SD card, the export fails and says 'file system of destination volume not supported'. How to fix?

When trying to move a project from Macbook Pro laptop to iMac, the program says, 'file system of the destination volume is not supported.'
This is true for both a thumb drive and a SD card. What is the fix? Thanks

Format them OS X Extended. Aperture libraries have to be on OS X Extended formatted volumes.
Use Disk Utility. Remember when you format a drive you erase all the data that is on it. So it there is anything you want on those copy it off first.

File system in JCOP

Is it possible to create and delete files (DF and EF) in JCOP cards? In other words, Is it posibble a file system in JCOP cards? If so, what tool and commands are used for? If not so, what Java card does support a file system?
Thanks in advance.

I also posted the question about the file systems some time ago.
Yes, Java Card doesn't support any type of ISO 7816-4 file systems. The reason is, i suppose, that Java card are not fully compliant with ISO 7816-4, but must comply to the GP 2.1.1/OP 2.0.1 specifications.
One of the solutions would be to create your own applet that implements file system and performs all the file system management command (delete/actvate/create file and etc.). As i remember, there is an example of file system applet in the Java Card Development Kit v2.2.2.
Reagrdinf OCF, I have no experience with it. It is not up-to-date technology, but a lot of people still use it for the terminal applications programming. I advice you to use JCOP tools offcard API, or Java 6 smartcard I/O API.

How do I use a NAS file system attached to my router to store iTunes purchases?

We have four Windows devices networked in our house. They all run iTunes with the same Apple ID so when any one of them has iTunes running, we can see that computer on our Apple TV. Two run Windows XP, one runs Vista Business, and the newest runs Windows 7. Upgrading all to the same Windows software is out of the question. Our NAS is hung on an "off warranty" Linksys E3000 router which communicates via USB with a 1TB NTFS formatted Western Digital hard drive. Our plan when we set up this little network, not cheaply, in our 1939 baloon construction tank of a house, was to build our library of digital images, music, and video primarily on that device. It supports a variant of Windows streaming support, but poorly. The best streaming support for our environment seems to be our ethernet connected Apple TV which is hung off the big TV in our family room, and has access to the surround sound "Home Theater" in that room. We've incrementally built up collections of photos, digitized music, and most recently educational materialsd, podcasts, etc. which threaten storage limits on a couple of default C: drives on these windows systems. iTunes, before the latest upgrades, gave us some feedback on the file system connections it established without going to the properties of the individual files, but the latest one has yet to be figured out. MP3's and photos behave fairly well, including the recently available connection between Adobe software and iTunes which magically appeared, allowing JPEG files indexed by Adobe Photoshop Elements running on the two fastest computers to show up under control on the Apple TV attached 56' Samsung screen!
Problems arose when we started trying to set things up so that purchases downloaded from the iTunes store ended up directly on the NAS, and when things downloaded to a specific iTunes library on one of the Windows boxes caused storage "issues" on that box. A bigger problem looming in the immediate future is the "housecleaning" effort which is part of my set of "new years resolutions." How do I get control of all of my collections and merge them on the NAS without duplicate files, or when, for example, we have .ACC and .MP3 versions, only the required "best" option for the specific piece of music becomes a candidate for streaming?
I envission this consolidation effort as a "once in a lifetime" effort. I'm 70, my wife is 68 and not as "technical" as I am, so documented procedures will be required.
I plan to keep this thread updated with progress and questions as this project proceeds. Links to "how to" experiences which are well documented, etc. may be appreciated by those who follow it. I plan to post progress reports and detailed issues going forward. Please help?

Step 1 - by trial and error...
So far, I have been able to create physical files containing MP3 and JPG on the NAS using the Windows XP systems to copy from shared locations on the Vista and Win7 boxes. This process has been aided by the use of a 600 GB SATA 2 capable hard drive enclosure. I first attach to Win 7 or Win Vista and reboot to see the local drive spaces formatted on the portable device. Then I copy files from the user's private directories to the public drive space. When the portable drive is wired to an XP box, I can use Windows to move the files from the portable device to the NAS without any of the more advanced file attributes being copied to the NAS. Once the files are on the NAS, I can add the new folder(s) to iTunes on any of the computers and voila, the data becomes sharable via iTunes. So far, this works for anything that I have completely purchased, or for MP3's I made from the AIC files created when I purchased alblums via iTunes.
I have three huge boxes full of vynl records I've accumulated. The ones that I've successfully digitized via a turntable attached to the sound card on one of my computers and third party software, have found their way to the NAS after being imported into iTunes and using it to bring down available album art work. In general I've been reasonably well pleased with the sound quality of digital MP3 files created this way, but the software I've been using sometimes has serious problems automatically separating individual songs from the album tracks and re-converting "one at a time" isn't very efficient.

File system error message

When I try to delete a media file it says file system error. Anyone know what this is and how to fix it? Thank you!

First off, your question really doesn't belong in this topic; you should post in something more appropriate.
That said ...
Where is the file located? On a microSD card or on the BB. How are you trying to delete it?

PS CS5 The operation could not be completed. A file system I/O error has occurred

Howdy...
I'm using Photoshop CS5 and when I go to use a handful of filters such as Liquify or Lens Correction I am suddenly getting an error message saying:
"The operation could not be completed. A file system I/O error has occurred"
Doesn't matter if it's a massive file or a small one. Sometimes the Liquify box will actually come up, but after I make one or two strokes, the beachball comes up and moments later I get the error message again. It doesn't actually crash PS, it just prevents me from using those filters. Each time I click, the error message comes up again. I've also tried it with my PS CS3 on the same Mac and it does the same thing. However on my 4 year old MacBook Pro, it's absolutely fine. Grrrrr!
I have my PS set as default on 64 bit. I have a scratch disk with nearly 500gb free (which is not my start-up disk) I am running a Mac Pro 2.8 GHz 8 Core Intel with 16gb of ram, so it's not a memory problem. Running Mac OS 10.6.7 but did the same on 10.6.6 too.
I have repaired the disk permissions on the start-up disk. I have reloaded a fresh copy of PS (a few times). Even did a hard Un-install with maccs3clean after trying a regular Un-install with no success.
I had an 1.5hr conversation with an Adobe Tech guy earlier today and he's scratching his head, so I'd thought I'd throw it open to you guys hoping someone has had the same problem and can save the rest of my hair from being pulled out.
HELP!

Hi Guys,
I know this is an old post but I need to bump it.
I work for a image processing company and we all sit on top spec mac pro's with 16-32 GB of RAM, top graphic cards and SSD drives.
All of my collegaues' computers are working fine when it comes to using liquify and all of the filters that come with CS5, but it sure doesn't work on my mac at all.
We have a tech guy who has re-installed the OSX on a new SSD drive now two times and we have started from scratch with installing CS5 but it still will not work. I keep getting "the operation could not be completed..." every time i try
to liquify or do any other filter work.
I am 100% sure it doesn't have to do with any disk permissions or broken drives in my case.
Could there be an issue with the graphic card or any other hardware component since it's clearly not a software related issue?
Any help would be much appreciated because we are very much in the dark here.
Best regards,
Anders

Camera attached with USB - How to access the flash file system?

OK...this is maddening for someone that is so used to using a Windows file system that can be enumerated on any device, whether a hard disk or attached USB flash device. All I want to do (at this moment) is see the file system on the flash in my camera so I can delete certain images. None of the Leopard utilities seem to be able to access this as a "device". Perhaps this can be done from the terminal with Unix/Linux commands...not something that I want to do.
Can someone help me?
Thanks.

This has more to do with the camera than OS X. Some cameras use communication protocols that do not play well with the Finder. For these cameras, support is built into iPhoto.
It is also built into the included Image Capture utility, which is more flexible than iPhoto in some ways for simple downloads. You can preview and select individual pics, and set the folder where the pictures go.

Almost all Canon and some Kodak cameras refuse to mount in the File System. It’s a characteristic of the brands.
In the case of Canon it is lack of support for USB Mass Storage which almost all other brands do. But as stated it is much better and safer to use a card reader instead of the USB cable. A card reader always shows up on the desktop for drag-and-drop.
