CRIO 9012 USB fix drive letter

Hello All!
I am using cRIO 9012 controller with 9102 chasis along with NI 9802 and IO modules in a system. I am logging data on SD cards and on USB drive connected with controller via USB port. I am using cRIO 2.4. Is there any possibility so that whenever I connect a USB
drive
to the controller and controller will assign a fix Drive Letter say
U without taking into account that the NI 9802 SD cards are mounted
or not. The problem is when I start the application.
Regards
Mani

Thanks for the VI Mangus,
From investigating the behavior, I'll help describe what is happening with your system to give a better understanding. When power is cut at some future time, anything thats using a FAT file system can and does become corrupt if its not properly shut down. So, as you have seen, when your application loses power, if the SD cards have not been un-mounted properly, then when we attempt to mount the Card, the software sees that the FAT file system has become corrupt and requires a run of chkdsk to recover it before we can mount again.
Now, this is different than some other OS versions, as others (Windows, etc.) are more lenient on the mount side. There are lots of minor corruptions that they are lenient enough to mount anyway. NI had an explicit desire to be strict and not lenient in these cases as if we mount filesystems that are corrupt in this way we might be overwriting any data that your application may have generated. So, currently, a proper system should have a way to provide a safe shut down procedure so that File IO can have time to close and un-mount the SD card. This could be done with an external battery on the input and monitoring on the RT controller on which Power Suppy Input is being used. See the Tutorial Designing High Availability Systems with CompactRIO and Compact FieldPoint for some more information on this subject.
We have considered providing a method to explicitly Mount and SD card even though its a little bit corrupt so please file a product suggestion if you would like to see this feature.
Let me know if you have any questions.
Thanks,

How do I get Lightroom to find photos on a USB Drive when the Drive letter changes?

THis is probably a simple question but I keep getting stuck. I ha
ve my catalog and some images on my laptop hard drive, but the majority are on
an external USB drive. Sometoimes the drive gets assigned
E:, F;, or G:, and when it cahnges, the catalog says the phots are missing. How do I get
Lightroom to find the photos again?
Tom Barnwell

The quick fix is to click on the folder containing the missing files and choose "update Folder Location" then find the folder on the USB drive. The longer term and fix you should apply is to set Windows to always give the USB the same drive letter. You can do this through the XP Disk Management application in Computer Management (Control Panel applet). The following screenshot is for XP, but Vista and Win 7 will something similar which can be accessed via Administrative Tools (see second screenshot).

Unmounting USB flash drive from cRIO

Hi all,
I am using the USB port of a cRIO 9012 to save datafiles (using File I/O) to a USB flash drive.
After having run the program, I want to unmount the USB drive. Can anyone please tell me if there is a better/nicer way than just taking it out? Since this might result into losing my data if the USB drive gets corrupt (just like under Windows).
I have searched the forums, but I was not able to find anything on dismounting a USB drive on a cRIO...
Hopefully you can help me solving this (little) problem.
Thanks in advance,
Joep

Joep,
under Windows there are two scenarios that could cause data corruption on a USB-Flash-Drive:
The Flash-Drive is removed during a write operation. This potentially destroys the FAT which results in data loss. There is not much that you can do against this behavior, neither on Windows, nor under VxWorks.
With caching enabled for the Flash-Drive there is a chance that files are not written to the drive completely because some parts of it are still sitting in the PC's memory. When the drive gets removed the data is corrupt.
I don't think that VxWorks uses cache for mass storage devices at all so this issue shouldn't be relevant for a cRIO-9012, but I will double check if this is true.

How do I find out about the driver letter of a usb drive by script, given the DeviceID

Hi all,
I am wondering if it is possible by script to find out what the drive letter of a usb drive might be.
I have just inserted my USB stick into a socked and the operating system displays that the drive was recognized and that the drive letter is F:.
I already know, how USB devices can be listed by WMI script, but how do I extract the drive letter of a USB storage device.
The DeviceID is known, where do I find the drive letter given the DeviceID ?

If you want the shuffle to be always visible in Windows (outside of iTunes), you need to Enable disk use.
Select the shuffle in the iTunes sidebar, under DEVICES. Over to the right, select the Summary tab. You should see a checkbox that says Enable disk use. Check it and click Apply.
NOTE: If disk use is enabled, you have to Eject the shuffle in iTunes, BEFORE you physically disconnect it. If disk use is NOT enabled, you can disconnect the shuffle at any time, as long as iTunes is not doing something with it at that moment (such as syncing); the shuffle's light will then be blinking (to indicate DO NOT DISCONNECT).
So, unless you want to use the shuffle like a USB flash drive (carry random files on it), you may want to NOT Enable disk use.

Thanks for the information and your help. I have never bothered before changing the format. Next time I will.
I copied the library to the external drive and then it went and said they were referenced files but I was okay about that. Now it cannot see them and will not do anything with them. I think I will buy another external drive and start again by importing all of my files again. I guess 55K will keep the mac busy this week.

[SOLVED] Toshiba 3.0 USB 2TB (HDTC720XK3C1) Assigned Drive Letter But Not Working

My external HD has 750gb of data that I cant access. It shows up with a hard drive letter, but doesnt show like it used to (showing how much storage is used and unused) or showing it's assigned name. It also doesnt work if I plug it into a different computer (does the same thing). I cant remember if I properly removed it when I unplugged it last night when I finished using it, so that may be the cause. I tried going to "manage drives" and uninstalling the drivers, but no luck. Tried rebooting with it connected, no luck. Tried unplugging for several hours and plugging back in, no luck. I do not wish to reformat the drive because of the 750GB of data I'll lose. Please help!

*****I FIXED IT!!!!!******* I continued searching the web and found the fix. All I needed to do was open the command prompt (cmd) and run this script "chkdsk /f E: (E: was the generic drive letter assigned). Basically windows runs check disk and fixes the problem. It also said you could try "chkdsk /r E:" but it worked on my first attempt. Make sure you allow the computer enough time to finish.... It took a long time for it to completely finish. (one way to know if it's done, you will be able to type in the cmd prompt again, if not, your computer is still working in the back ground) After it was done, I ran my windows defender to check my removable drive for virus's and sure enough it found 3 threats.
I HOPE THIS HELPS ANYONE ELSE WITH THE SAME PROBLEM as it seems like a relatively easy fix, but over 80 people had read my plee for help with no response.

Changing iPod drive letter fixes "could not mount ipod"

So the problem I was having is that although my Windows XP SP2 machine could see my iPod nano as a drive, whenever I tried to use iPod Updater or iTunes, they could not connect/recognize the device. iTunes would simply not see that I had the device, while the updater would freeze for a good 5 - 10 minutes before giving me the "could not mount ipod" error. I tried everything, selective startup, windows update, made sure that I did indeed have USB 2.0 hardware, made sure that when I connected the ipod that Windows Device Manager said it was a "Standard ENHANCED USB Hub," restarted ipodservice, formatted ipod using windows, and probably a few other things. Still, although Windows could see the ipod just fine, apple's software just could not. I could even copy files to and from the device just fine! If only we didn't need iTunes to copy music. :P
Well, one thing I suspected it could be is that with my computer, my primary hard drive (and I only have one) is mysteriously drive letter "D" while when I plugged in my iPod it took on the holy "C" drive letter. Could this be a problem? Possibly, but not likely I thought. So I tried some 3rd party software which emulated the ipod software and I got an error message. First that it appeared my ipod was not formatted (which it was) and second that it "could not create :\ipod_control". First thing I thought was, where is the drive letter? The software isn't even looking for the ipod in C:\, it's looking nowhere! So what I did it changed the ipod's drive letter from C to something else and viola, it worked.
So it seems the iPod may not like it when it is named C, or there was some conflict with the iPod using the C drive letter since, I'll admit, I used to have two hard drives and the other one used to be C. Could also be a bug, who knows.

Welcome to Apple Discussions.
Ah, the Drive Letter C problem again.
The iPod software and iTunes will not recognize the iPod if it is assigned to drive C. Changing the drive letter to a higher one not used by other drives will solve the problem.

Disk manager not assigning usb enclosure drive a letter

LAPTOP: Toshiba Satellite 1135-S155 Windows XP Home Edition.
current preinstalled 40 GB HDD message says it is failing & backup. want to backup to usb enclosure using western digital 80 GB HBB (didn't want to shock the system). computer does detect my toshiba 4 GB flash drive & assigns drive letter E. DEVICE MANAGER detects the western digital hdd as: usb device generic void disc, PROPERTIES claims Location 0; VOLUME shows Disk 1, unknown, unreadable, partion style as Not Applicable, 0 MB. Disk Management does not show usb device thus doesn't even assign a Drive letter to it. not attaching any other usb device while i have usb enclosure hdd hookup. have gone through troubleshooting, reinstall, basically what i can find to do from "Windows XP Inside Out Manual" unless not looking in right place.
Should i place new western digital 80 GB HDD into computer, use original restore discs that came with system, then place old 40 GB HDD into usb enclsoure and copy that hard drive onto the new 80 GB HDD? Or what?
found a hero once in this forum & hopefully will find you again. love my old clunker & don't want to give her up yet!

Hey, I'm back. And with SUCCESS!!!!
Was able to take new hard drive and connect to a laptop running VISTA. VISTA recognized the new hard drive that was in the same USB external enclosure that I was using. VISTA recognized in both Device Manager & the much needed DISK MANAGER. Was able to initialize immediately w/no problemos!! YIPEE SKIPPY.
Did I dare to be BAD? You betcha! Took the initialized HD back home & hooked up to the TOSHIBA Satellite 1135-S155. Again, success. My old DISK MANAGER saw it, I was able to continue to partition & format it!!! Why WinXP Home Edition couldn't initialize it? - Is one I'll leave for the cosmos.
Anyway - Who says you can teach an old dog new tricks - HA! Little did they know about ME - oh, ahem, and of course JERRY aka The HERO and also The Wondrous CEE-64.
So excited was I, and how could I NOT be? That I immediately tried the FREE Acronis True Image Western Digital Edition that was suggested by The Wondrous CEE-64 on the 08-29-2009 7:03 PM session. As I was hoochie-cooching around in my NEWER SHOES, I suddenly I noticed that after burning 'Volume 5' onto a CD-R - ERROR MESSAGE (Error occurred while writing to file), hmmm - inserted a different CD-R, again same message, hmmm - inserted a different CD-R yet, hmmm - same message & got the hint. Shall I go on? OK you asked for it.
After checking Western Digital website & running one of their programs. The initialized, partitioned, formatted WD Scorprio Blue HD was just being recognized as a USB Generic Mass Storage Device. Hmmm - maybe because the Western Digital Edition couldn't detect the new hd being from WD, could that be the problem? Closed and uninstalled the FREE Acronis True Image Western Digital Edition.
Per HERO Jerry's suggestion on 8-27-2009 12:00 PM, I downloaded FREE Acronis True Image 2010 Home Edition. Loaded fine, reread the users guide (serveral times). Attached the USB external enclosure (YES, the hard drive was inside) started the program, used CLONE DISK option, TA-DA it worked.
Yep, it has to reboot. Okey-dokey. UNTIL it came to me having a problem. This TOSHIBA requires an F1 button to be pushed after start up AND it doesn't like the USB GENERIC MASS STORAGE DEVICE to be attached during boot up. It stops & requests either F2 (setup) or F_ (I forget) and doesn't respond until I 'safely remove the USB device', then the F1 button. SOMEHOW, after swapping out the drives (THAT went really well, pat on the back) & Started the computer up. YUP, Toshiba intro screen pops up, then the F2 etc. screen, & waited longer than usual. Pushed the F2, saw that it is the WD drive with larger capacity, exit, then a dark screen with a flashing cursor in the upper left hand corner came on. That was it. Nothing for a minute or two, tried just shutting the laptop off. Wouldn't. Ended up swapping the hard drives while the fan was running. Using the old TOSHIBA 40GB drive again.
Whada say? One more time for old times sake? Or should I just hang it up? What do I do now, pleazzzze and thank-you.
PS - Can't wait, this stuff is getting good!

Request BIOS to fix an USB flash drive boot problem in EFI (GE60 0ND-265FR)

Hello,
I'm currently trying to install Ubuntu on my MSI GE60 0ND notebook but I'm having troubles to boot on my USB flash drive in EFI mode.
I've disabled Fast Boot and Secure Boot options but the only thing I can have is the GRUB menu of the liveUSB and whatever option I try I always get a blank screen. On the other hand everything works fine when I set the BIOS on Legacy mode.
It's the same problem they have on this thread : https://forum-en.msi.com/index.php?topic=165756.0 but with an other notebook.
The problem is I want to keep Windows 8 side by side with Ubuntu so I must have them both installed in EFI mode.
I asked for help on a specialized forum (french Ubuntu's community) and they believe this problem is related to the BIOS. Do you think an unlocked BIOS will help with that ?
Here are my current BIOs and EC infos :
BIOS Version : E16GAIMS.514
BIOS Build : 03/12/2013
EC Version : 16GAEMS1 Ver5.05
EC Build : 02/21/2013
Thanks for your help, and sorry if I've made English mistakes.

i don't know if unlocked BIOS can help you with this

Lightroom 5 can't import to a FIXED drive called A: or B: even if that's where your catalog is

This what I consider a bug for lightroom 5. It simply does not allow you to import to a fixed hard drive called A: or B: even if that is where the catalog was opened from and where all your other photos are stored.
Yes I know why... A: and B: used to be used for floppy drives back in the stone ages... however windows has allowed you to assign them to hard drives for decades now, and as time goes on, you are going to be seeing a lot of computer users who have in fact never heard of a floppy drive and have never even seen a floppy disk.. it's just something they heard about in history class.. if they weren't sleeping.
You will be getting more and more technical support issues when the following scenario happens...
I was running out of room for my data, so I went out and bought me a nice new huge drive... Installed the drive per the instructions and went to 'disk management' to add an additional drive to my system..   It eventually asked me for a drive letter, and A: was at the TOP of this list, so I used that...   then formatted the drive and all was great.. windows reports a fixed drive called A: with a ton of free space... so I moved all my lightroom data to A: and opened the catalog from A: and it started lightroom just fine.. and all my photos are there and this is great!    You can do everything with the hard drive being A: or B: so I'm done messing with it... well a few weeks or months go by, and I've long forgot about the install process and now I have 13 other applications using my A: drive and I finally have a break in my busy schedule so I go out and shoot some photos.. I get back, install my memory card in my computer and prepare to import my files to the hard drive where my catalog is...... but I CAN'T!!! A: and B: do NOT EVER show up in the lightroom list of drives... and WHY NOT??? I can't understand why lightroom can't import to something my operating system is reporting as a FIXED drive.     Now I have all this stuff on my huge drive called A: or B: and it's going to be a huge task to re-assign that drive to another letter because all these other applications will be looking for their stuff on A: or B: Ugh
Ok, so Adobe is trying to save us from ourselves and not allow us to try to import to a tiny disk that could not even hold one of our photos... uh... WHY? Just put A: and B: in the list if the operating system is reporting them and if someone DOES have a floppy drive, called A: or B: and they try to import something to it.... they will just get an error saying it won't fit... problem solved!    What is REALLY ironic is that lightroom WON'T EVEN RUN ON ANY MACHINE WITH A FLOPPY DRIVE IN IT!!!!    You could put a USB floppy drive on your windows 7 or 8 machine... but when you do that... it's NOT necessarily A: or B:... you can make it whatever you want... leaving out A: and B: doesn't help ANYONE at all.
Now, assume this user is in their early 20's... they have never ever seen a floppy disk, and could not buy one if they wanted to... which they don't... they just can't understand why this is happening.. why is my huge drive NOT in the list??? why is it not there? I don't understand this.
It should be noted that this also happens if A: or B: is a network drive as well.    Floppies have been obsolete for a long time, and in fact you haven't been able to buy a new computer with a floppy drive since 2005, and they were completely useless back then.. and B: drive has been useless even longer!
So, what has happened here... is leaving out A: and B: has just been carried over from decades ago when it was probably a good idea... and no one has even looked at changing it.   People do have problems with this though, but it won't be fixed until someone says something... So I'm saying something. fact:    A: and B: are NOT reserved for floppy drives anymore.. they have not been for a very long time fact:    No one will ever plug in a floppy drive ever again.
fact:   Windows has allowed network drive and fixed hard drives to be A: or B: for decades
fact:   You SHOULD be checking the operating system to see if a drive is fixed or removable and what it's capacity is... not making assumptions about the drive configuration
fact:   As time goes on the the more and more people who have never heard of a floppy disk increases, this WILL become more and more of an issue.
fact:   There is no reason to NOT be using A: or B: for network or fixed hard drives... and our software should allow us to do so.
fact: I want my 4TB drive to be B:!   but I have to settle for it being WAY down at T: because I've used all the letters down to S: already... heck my usb 3.0 card reader alone takes up 4 drive letters.. and I'm used to them where they are now.   I also want my RAID box to be a network A: drive.. putting it right there at the top of the list!
I'm settling for other letters, at the moment.. I actually moved my nearly useless DVD burner down the list.. do you all realize even DVD's are becoming obsolete??? why burn a measly 5GB on a DVD that is so fragile and easily scratched... when you can just write files on a 128GB flash drive? (yes there are even 512GB flash drives available now) It's only a matter of time before NO one will have ever heard of or seen a CD, or DVD disc either!

Probably the best place is here http://feedback.photoshop.com/photoshop_family/products/photoshop_family_photoshop_lightro om . Not sure if it's taking new registrations though.
I'm a little susrpised that it's not possible, and I agree it's a bit silly in 2013, but my guess is it's one of those things that won't change for a while. They've probably played safe, and to be frank, whenever you break such old rules (eg 32 characters, case-sensitive filenames, punctuation in filenames etc) it's only a matter of time before you get bitten by something. I just wouldn't expect Adobe to spend much time on it - it's not as if they've nothing else to work on.

External USB Hard Drive Can't Be Safely Removed After Boot Camp 3.1 Install

I just wanted to report that I've done multiple installs of Windows 7 Ultimate 64-bit on my MacBook 4,1 and although I've had no problem using the cmd workaround ( http://www.zath.co.uk/how-to-install-windows-7-on-apple-mac-boot-camp/ ) to install the 64-bit Boot Camp drivers that come with the Mac OS X 10.6 Snow Leopard retail DVD, I have found that by installing the Boot Camp 3.1 drivers on the same system, under no circumstance can I click the the "Safely Remove Hardware" icon in the system tray and not receive a message saying that ... "The device 'Generic Volume' cannot be safely ejected..." and that some program or service must be using it. However, a restart doesn't solve the problem any more than logging out does.
I read somewhere that part of the fix that Boot Camp 3.1 was intended to provide was to allow safe ejecting of the Macintosh HFS+ partition. Well, my external hard drive has three partitions: one NTFS, another NTFS, and a third HFS+ for Time Machine backups. I suspect, since I haven't seen anyone else reporting this issue, that it may simply be that the Boot Camp 3.1 drivers don't take into account the possibility of an HFS+ partition on external USB devices. Anyway, a System Restore to before Boot Camp 3.1 drivers were installed completely remedies the issue.
At this point, I'm not having any trackpad issues or anything else of note with respect to the original Boot Camp 3.0 drivers that came with the Snow Leopard retail disc, so I'm fine keeping those drivers installed and allowing Windows Update to update the Intel and Marvell drivers as it recommends. I just find it slightly amusing that the Boot Camp 3.0 drivers, which supposedly did not support Windows 7 (let alone the 64-bit version) work better than the 3.1 drivers which do supposedly support Windows 7. And the funny thing (or is it?) is that you have to install the original Boot Camp drivers with the cmd workaround before you're even able to update to the Boot Camp 3.1 drivers. Hilarious stuff there.
Proprietary gamesmanship is a big reason some of us prefer the Linux "share the ownership +for free+" model of computing. Just saying...
Anyone have any proper solutions (as in, other than "don't install the updates then!")?
bkadoctaj

I have a pair of external usb drives, one formatted for NTFS and the other for HFS+ connected through an external 7 port hub. I am running Windows 7 (64 bit) with bootcamp 3.1 on a late 2009 Mac BookPro. I share the same "safely remove hardware" issues you described. I always assumed it was because my external drives were connected through my external USB hub because of a similar issue I had running Vista (64 bit), but now I can confirm directly connecting the external USB HFS+ drive also yields the same "safely remove hardware" problem. Unfortunately for me, if I regress to the Bootcamp 3.0 drivers, my audio drivers, at times, fails to load. I would need to regress to Windows Vista (64 bit), the last environment where my iSight camera, internal speakers and all other hardware performed correctly. I would gladly, at this point, live with the "safely remove hardware" issue in exchange for a working iSight camera, the one and only hardware device lost to me in the move to Windows 7.

Airport "sees" USB hard drives, but Finder can't find them!

Yesterday, my iMac's Finder could see my external USB hard drive connected to AIrport, but not today. Airport sees it right now--I've checked and updated it and restarted it. Finder still can't find the drive. I click on my Airport connection in the Finder sidebar, my usual route to the hard drive, but the connection window hangs. And hangs. I need access to the files on that hard drive. Problem is, another iMac using Tiger needs access, too, so I can't disconnect arbitrarily. With that iMac, Tiger's Finder sees the files, and can access them. But not this 20" 2.4G iMac with Leopard 10.5.3. What's going on?

floba,
the first solution, clearing the entire index and letting it rebuild, did not work.
But setting the drive in 'privacy' and then removing it did immediately work, my search window which was left open refreshed instantly to reveal my items. I'm curious however if it will stick..
i have another issue that may be completely unrelated, but maybe not..
i clear my spotlight shortcut key (command+spacebar) because it conflicts with common Adobe app commands i use. But i frequently will find that this shortcut key is RE-ENABLED. At the same time, my shortcut to use Spaces (command+f8, command+arrow keys, and command+numk keys) are CLEARED as if i had never set them. This happens consistently and is frustrating. I don't reboot very often, but i under 10.5.2 i often came home to find my computer has locked up, so it would seem these shortcuts all reset when i reboot, and i wonder if my external drive index is lost every time the drives are ejected.
Vista's completely useless search features were a main reason i gave my PC's away and bought macs. I'm obviously finding these failings frustrating on the mac. I'm even more disappointed at the news Snow Leopard is a bug fix and is selling as a separate OS. Installing additional programs is not an option, i want the OS to do what i tell it to do /rant
