Can't read from or write to????

help me. My son's computer died and we connected his ipod to his sisters laptop. We downloaded the latest itunes and ipod updates. it says that the ipod "cannot be read from or written to" when we try to update it. Of course, I'm 20 days out of warranty. Can anyone help me and tell me what to do?

See if anything in this article helps: "Disk cannot be read from or written to" when syncing iPod or "Firmware update failure" error when updating or restoring iPod

"Can't read from or write to disk...." iPod error

I recently switched from my old PowerBook G4 (running Leopard 10.5.2) to a newer MacBook Pro (running Leopard 10.5.5). I migrated my account and permissions from the PB to the MacBook Pro, and everything is working just fine except for iTunes (version 8.0.2) and my older 160 GB iPod Classic (running 1.1.2).
NOTE: THE VERSION OF iTunes ON THE PB WAS VERSION 8.0.1.
Since the migration, I've been getting this "can't read from or write to disk..." error whenever I attempt to sync my iPod to iTunes. Previously, I'd never had any problems. I have tried to restore the iPod using iTunes - didn't work. I have tried different USB to dock connector cables - didn't work. I have even tried completely re-formatting the iPod using Disk Utility - didn't work. Everytime I begin syncing the iPod, it starts out just fine. At varying degrees of completion it ALWAYS fails with the same error.
I had an idea. I tried syncing the iPod to a different computer - my G5 4 x 2.5 GHz (running Leopard 10.5.5) with iTunes (version 8.0.2). I still got the same error. I haven't dropped it, submerged it in water or done anything to it that would otherwise compromise its functionality. So, I'm at a loss.
PLEASE! PLEASE! PLEASE!
Does anyone have any other suggestions? - OTHER THAN BUYING A NEW IPOD

UPDATE:
OK, after the visit to my Genius Bar; I thought of a variable that wasn't previously considered. Because their transfer of media was successful without the slightest hitch, I had to figure out something else.
Everytime I had tried to sync the iPod with my various Macs, I was using the same process. Since all of my music and movies "live" on an external 500 GB drive, I was attempting to use that same drive whenever I would try to sync. It occurred to me that possibly the failing was in the drive and not the iPod.
I have part of that library on a Power Mac G4 867 DP (running 10.4.9). I updated the iTunes on that machine to 8.0.2, connected the iPod and made a successful transfer of a large amount of media!
My only problem now is that I can't figure out how to get the 500 GB drive to stop hanging on transfer and update of my Genius information. The drive just completely stalls and I get the spinning wheel from iTunes and the application ceases to respond. When I force quit iTunes, the drive recovers fine. I don't have any problems transferring data to and from it and Disk Utility reports that the drive is healthy.
I have tried re-installing iTunes on all affected Macs - didn't help. I believe my problem may exist in the iTunes Library file or in the associated .xml document. My only concern is that if I do a completely fresh install of iTunes where those files would be re-created, I would lose all of my play and ratings data as well as the information about when my files were added. On a related note, when playing the music from this drive through iTunes. I don't have any issues at all.
ANY SUGGESTIONS?

Zen - Can't Read from or Write to Your Pla

I recently bought a Creative Zen and had no problems with the software until recently one day when I was trying to work with a playlist, it said it could not read from or write to my player. I tried a different computer with a different operating system, installed the playlist manager disk on that computer, and got the same result.
Additionally, when I try to record something, the player freezes up. However, the big issue for me is not being able to manage my playlists at all. I can still download books and tunes and get updates from Creative, so that's not the problem.
Any help? I looked in the FAQ for this, but the link is broken.

Converting WAV files to AAC Error convert Can't read from or write to disk

For several weeks I had no problem converting WAV files (from an Olympus Digital Recorder) to AAC format in iTunes, then one day I clicked "Convert Selection to AAC" and received the message "Error occured while converting the file. The disk could not be read from or written to." There is no Error # associated with the Error message.

I recently spent over 14 hours converting all my CD songs to WAV. WAV conversion was the only one of two options available with my older Nero software, and MP3 conversion was not an option. I intended to make mixed CD's. By the time I was done, I had over 300 songs that take up over 17 GB in this WAV format.
The thought of sitting even more endless hours making these CD's made me even more exhausted, and I realized that I should get with the times and get an MP3 player. So, I bought an iPod directly from Apple two days ago (12/16), and get this, MaclessInAZ, the sales person told me that I all my WAV files could be imported into my iPod with iTunes. (!!!)
I am very glad to have read this thread before I got my iPod. I would have been so upset if there was no easy solution. My new iPod is supposed to be delivered tomorrow, and I am looking forward to getting it. Many thanks to weavercs for the information on the Switch program that converts WAV to MP3. Even if I decide to buy the full version of Switch, it is a lot less expensive than other conversion programs that I just found online, like Roxio.

IProblems=Can't read from/write to and Flipping through songs

Yeah I'm getting the error "Can't read from or write to.", and the iPod itself will turn on, but when I put it on a playlist or album, it starts flipping through all the songs before it even gets a chance to play part of the songs. What gives?

Please do a Restore - which erase all the music on your iPod.

How to read from and write into the same file from multiple threads?

I need to read from and write into a same file multiple threads.
How can we do that without any data contamination.
Can u please provide coding for this type of task.
Thanks in advance.

Assuming you are using RandomAccessFile, you can use the locking functionality in the Java NIO library to lock sections of a file that you are reading/writing from each thread (or process).
If you can't use NIO, and all your threads are in the same application, you can create your own in-process locking mechanism that each thread uses prior to accessing the file. That would take some development, and the OS already has the capability, so using NIO is the best way to go if you can use JDK 1.4 or higher.

You've got to be kidding me...
I'm trying to create a simple message service between
a server and J2ME client. But everytime I try to read
from DataInputStream (dis) i get Exceptioons. How
come? It works just fine to send messages to
OutputStream.What exceptions get thrown? What line numbers do they get thrown from? Do they always get thrown, or only in certain situations? Put your code in [code ] blocks (http://forum.java.sun.com/faq.jsp#messageformat, for Christ's sake, how many times do people need told to do that... it should just be written write on top of the page that you type your posts in... oh wait... IT IS!)

"Unable to read from or write to your play

When I go to create a playlist with the music that is already on my Zen, this pops up. Why isnt it working? Its probably something really simple that I overlooked... but Im stumped. I came here as a last resort

I received this same message and came on here to find some help. I am using the new Creative Zen, 6 gig.
I am using a Windows Vista computer.
When the player is docked and I am using the Zen Media Explorer, I go to "create playlists"
The player loads, I can see all of my files and most of my music on the creative playlist wizard. I clicked on one file (containing most of my music) and this message pops up. "Unable to read from or write to your player"
Any suggestions?

Windows Easy Transfer (WET) Issues with External Hard Drive - "Can't read from the source file or disk"

I work for Office Depot, in the tech department. Basically, one of our associates was supposed to do a data backup, and re-install Windows 7, then transfer the files back. He used Windows Easy Transfer and compacted everything into a 163 GB file.
Now comes the hard part. When we try to put it back on his computer ((drag-and-drop to the desktop) which has been wiped back to factory settings using the recovery partition), it stops at 79.5 GB remaining (you know how it doesn't give you a % of completion,
it just shows how many GB are remaining) and then says "Can't read from the source file or disk" and gives you an option to try again, or cancel. It gets hung up on the same point each time.
Normally, this wouldn't be a huge issue, but the contents on the drive are his wife's architect blueprints and interior design stuff, along with wedding photos, etc, which are the only copies they have. On top of those, they have court documents and other
important files that we are unable to access now.
I wasn't involved with this transfer, so I'm trying to clean up the mess as best I can. I remembered that the customer's wife was Russian, and had some files typed with a Russian keyboard, so on and so forth. I wonder if that's the issue? If not, I really
have no idea how to manually extract things from a ".mig" file, or how to diagnose what area is potentially corrupted.
In light of this situation, we tried using "Recuva" to recover the files post-wipe, but everything was corrupted or unable to be opened, and it also extracted and recovered all of the "useless" photos, such as the skype logos, up and
down arrows for browsers, etc (it was 160,000+ photos).
Trying to avoid a potential lawsuit, unhappy customer, and costing the company lots of money to see if professionals can get into this external hard drive.
Other relevant information:
We used a Toshiba 500 GB (465 GB) external hard drive.
Customer's computer is an HP Pavilion P6000 Series (Model No. p6520y) running Windows 7 Home Premium 64-bit Service Pack 1.
Any other information that is needed can be provided, thanks in advance, and hopefully we can find a solution to this issue quickly!

I think there's a lack of understanding somewhere.
"If you even can't start the process, please unplug it from your new PC. Then head back to your new computer and plug
the external drive back in to your new computer. "
Unplug from new, head back to new, plug it back in? That doesn't make much sense! Haha.
I knew what you meant though, somewhat. When I search through the drives after clicking yes (Has windows easy transfer
already saved your files blah blah blah) I click on the transfer file and it says "Windows Easy Transfer could not open the file".
Rather than drag-and-drop the file to the desktop, I now tried to double-click on the file itself while it was plugged
into the computer. It opened, and it started transferring until it was about 70% completed, and then an error popped up saying "WET can't open the easy transfer file, make sure your USB device is plugged in or check your internet connection".
I checked, and the USB hard drive's light wasn't on. Now, I unplug it and plug it back in, and the light comes back on,
so I click Retry, and it resets the bar back to nothing and says "Transfer time: 1 minute".
Rather than continue trying, I clicked "Cancel" instead of Retry, and it says "Your transfer did not complete successfully."
It says to click "view report" for more information, but there's no "view report button".
At the moment, I am scanning the External Drive for bad sectors using the check disk tool in properties. It's frozen
at "0 USN bytes processed".

Can't Read from Source File

Hi Guys
I'm using PPr CS5 on Win7 64bit.
I'm not sure if this is strictly for here but can I pick your brains please? I edited in PPr and exported three versions of the same video to AVI (mainly different intros and titles) and they all play fine. I back up my movies to an external disk but one of them always creates an error in the back-up "Can't Read from Source File". The file sizes are 5.3gb for the offending movie and 8.3 for the other two.
I know the answer is to re-export the movie but I'm just trying to get a bit of a handle what could have caused this problem in the first place and if this is a common problem?
Any views?
Regards,
Graham

That doesn't help much. What exactly are you doing when you get the error message?
Are you trying to open a PP project which contains the file?
Are you trying to play a sequence which has clips from that file?
Are you trying to play it in a media player?
Are you trying to import the file into PP?

"Unable to read from or write to your player" Zen 1

I have a new Creative Zen 6G and am using Windows Vista. While using the Creative Media Organizer, I tried to create a new playlist. The player shows all my folders, and when I try to open the folder that contains the majority of my music, the message "Unable to read from or write to your player" appears. Does anyone know what this message means or what I have to do to fix it's Thank you-Melissa

Have you tried adding from a folder rather than iPhoto to see if that makes a difference? Create a folder on your hard drive called called "iPod Photos" or something similar and drag the photos you want on your iPod to it. Under the photo preferences for the iPod, point iTunes to "synchronize photos from" and choose to update from your new folder.

Managed Metadata (Failed to read from or write to database. Refresh and try again. If the problem persists, please contact the administrator)

When creating a new site column of the managed meta data type in SharePoint2010, and you select "customize your term set", you are presented with one of the following errors:
- This operation cannot be completed. The term store may be unavailable.
- Failed to read from or write to database. Refresh and try again. If the problem persists, please contact the administrator

Hi,
I have been facing the same issue, however managed to resolve it.
This is due to the uncommitted statements. From Powershell try running the following script
#Connect to Central Admin, Replace the url with the environment specific URL
$taxonomySite = get-SPSite http://centraladmin:40000
#Connect to Term Store in the Managed Metadata Service Application, Ensure you put the right Metadate service application name
$taxonomySession = Get-SPTaxonomySession -site $taxonomySite
$termStore = $taxonomySession.TermStores["Managed Metadata Service"]
write-host "Connection made with term store -"$termStore.Name
#Connect to the Group and Term Set
$termStore.RollbackAll()
Hope it would help
