File finished written to disk verification

Hi guys,
for instance, there's an incoming huge file like 100MB. so how can I use java code to check if this file has done written to disk in unix box before I grap this file to upload to another location.
Please help, thanks !
Mark

Have the process that is transferring the file notify you when it has finished transferring. One method of notification that works well is for the process to rename the file to something you can poll for.

Moving library to external hard drive and get the error "Copying files failed. The disk could not be read from or written to"

Hello,
I'm moving my library to an external hard drive.
I've made sure to use the 'Keep iTunes Media Folder Organized' option when pointing to the new library location.
I select 'File'->'Library'->'Organize Library', I select to 'Consolidate Files', click 'OK' and get ther error message "Copying files failed. The disk could not be read from or written to".
I've read elsewhere that there may be a corrupted file that I need to sequester somehow and perhaps add it back however I'm not certain how I can locate that file because the status window doesn't indicate which file it's attempting to transfer when the error appears.
Any tips?
Thank you,

iTunes 10.6.3

OK I figured it out!
It was a dodgy file....I sorted the file folders by date, and as it turned out within the "compilations" folder there was a CD where only about half the tracks seemed to have been copied over. Could not have identified this simply from the time indicated on the finder folder sort, because there were several CDs copied over in the that same minute.
I went back to the original itunes folder, deleted all the files from that CD in itunes, then also deleted all those files from the original disk and the target disk.
Tried the "consolidate library" again, and it completed nicely. 200megs of music and videos.
Very happy to solve this problem after 3 weeks.

InDesign CS6 "Failed to export the JPEG file. File cannot be written. Disk may be locked or full."

I get this error "Failed to export the JPEG file. File cannot be written. Disk may be locked or full." when sending small (3"x3") and large (40"x60") files to a printer hot folder. Sometime if I close the program and restart it will let me export. What could be causing this to happen?
I am on Windows 7 with 4GB RAM PC.

I guess the printer is grabbing the file before it is entirely written…
Workaround: Do not save to a hot folder. Move the files after exporting to the hot folder.

The license file will not be written to disk...

I keep having to write the serial number and user information when I run Final Cut Pro and any other Final Cut Studio apps.
It says: The license file will not be written to disk because the user does not have enough privileges.
So everytime I open a final cut studio program I am asked for this information again before running.
This is REALY annoying. I tried reinstalling, and it wouldn't help.

Click here and follow the instructions.

Can i delete a file on my external disk?

I have a toshiba external hard disk. When i plug it into my macbook air, i can only see my documents and copy them to the macbook or copy files from macbook to hard disk. But i can't delete any file on my external disk. How can i can do it?

It sounds like you originally used this drive with a Windows PC. Drives formatted as Windows NTFS can be read by a Mac but not written to (files cannot be deleted). If you want to keep the files that are on the drive, you can use Paragon NTFS (it's about $20) to install a driver allowing your Mac to write to the drive and delete files. This will allow you to continue to use the drive with both Mac and PC.
Or, if you have copied off all the files you need, you can use Disk Utility in your Utilities folder to wipe and reformat the drive to Mac format. You will no longer be able to use the drive with a PC.

Forcing the disk cache to be written to disk

Hi all. We are looking for a way to insure the content of the icommon in the ufs on disk as we need to read it. However, calling sync is async and does not seem to provide what we're looking for. When a file is updated, created all the information is not immediately written to disk. It is kept in the unified memory and later flushed to the disk cache which then writes it down on the media. However, since we're reading the hot FS we need to force ALL file metadata AND data to be written to the media.
Seems like when I run the command 'ff', probably as a side-effect, this is happening. ff takes too long and is at the FS level. Is it a side-effect, or does 'ff' calls a specific func (truss did not reveal anything useful).
Thanks all and best regards.

I. What is really happening under the hood?
1.sync(2) passes execution into kernel mode
2.kernel function syssync() is called then
3.then vfs_sync(0)
4.eventually ufs_sync(vfsp,�) is called with NULL as a first argument
in case of NULL(as a 1st arg) ufs_sync() just schedules but does not necessarily completes the writing of ufs metadata before returning.
So, this behavior completely matches with one described in man section for sync(2).
II. directio does not solve your problem because it affects only the way the file data( not metadata) goes to disk. ( read directio(3C) and mount_ufs(1M) carefully )
III. What you really need
May be it seems to be a heavy weapon for you but one of the possibilities is:
To write a loadable system call (loadable kernel module) that will
invoke ufs_sync() with proper arguments (non NULL vfsp) for mounted file
system of interest.

Lightroom cache files permanently written to alternate drive

I've encountered an unusual problem using LR version 1.4.1 under Windows XP. Whenever I preview a RAW file in LR, a cache file is being written to an alternate drive, named Cache0000000001.dat, with each additional preview increasing the last digit in the file name by 1, Cache0000000002.dat, etc., and an Index.dat file. Each cache file is 2532kb or 8607kb depending on the size of the original RAW file. After closing Lightroom, these files remain on the disk and have to be manually deleted.
This has only begun to happen in the past couple of days. I therefore assume it's due to some change I've made recently. The change began after I removed Photoshop CS2 after having both CS2 and CS3 installed for several weeks. I don't know how the particular disk for writing these cache files is being selected other than the fact that my CS3 scratch disk is the same disk. The Lightroom files are on a separate disk.
This is not a major problem except that the cache files add up very quickly, taking up a lot of disk space and must be deleted manually after closing LR.
There is probably no simple explanation for this anomaly but if anyone has any ideas, I certainly would appreciate the input.

Ian,
Thanks for the reply. Yes, you are correct. The preferences in Camera Raw determine where these cache files go and does limit the size of the total cache. The default is 10 GB which suits me fine. Where these files have been going in the past is a mystery to me.
It does seem surprising to me that the location for the Lightroom cache is
determined in Photoshop Camera Raw but so be it.
Again, thanks for solving this problem for me.

Enabling FileVault 2: "Boot file not written"

I receive the mentioned error promptly after entering my passphrase. The terminal output is:
Started CoreStorage operation on disk0s2 Mac HD
Resizing disk to fit Core Storage headers
Creating Core Storage Logical Volume Group
A problem occurred; undoing all changes
Reclaiming space formerly used by Core Storage metadata
Error: -69853: Boot file not written
With the sparse information floating around the web, this problem seems to stem from the fact that I just installed a new Harddrive and cloned my old one with Carbon Copy Cloner.
Are there any ideas on how to get my Harddrive FileVault ready?

Here's what diskutil list gives me:

Autowrite XMP problems - unchanged files are updated on disk

I have experienced the same situation that is described here: http://www.adobeforums.com/webx/.3c0581ca/2, namely that files that are not changed by me in LR are updated on disk.
I have a test library that has "autowrite XMP" turned on. What I disovered today wast that when I opened up a folder in grid mode, all files were changed on disk, even though I made no changes to keywords, metadata or adjustments. So, just after opening up three folders and just looking at the images in grid mode, I suddenly got 60 modified files on my disk. This goes for both JPG and RAW files (for RAW I get modified XMP files).

Hi;
The problem is solved, touch wood :-);
No, it didn't help to "refresh". But your suggestions made me think along other routes...
First a few words about the application. The application uses a Database, written in Filemaker 10 pro, which keeps track of hundreds of documents. Document may be added, replaced or deleted (on daily basis). The FileMaker database generates and exports a part of the HTML code (a hierarchic structure created with <li> and <ul> commands) that constitutes one third of the HTML-code required for building a menu. In this way the documents could be accessed over the intranet. Hence, DW is used to develop the web interface, and FileMaker contributes by supplying the foundations of a web menu (all according to standard HTML formating).
Back to the "problem". The FileMaker data base is written in Swedish. In Swedish we have three more letters than in English; abcde...xyzåäö, the three last are a with a ring, a with two dots, and o with two dots. We also use the é (e acute). It seems that Filemaker and DW doesn't like each others way of creating these letters. The solution was to add a piece of Filemaker code that replaces å with å and the same for the other letter ä Ä å Å ö Ö é and É. A solution would, perhaps, to change the character's encoding in the document. But I believe that replacing the "odd" letters is a more stable solution.
This SEEMS to have solved the problem.
Murray, Thanks for your comments

Can't turn on filevault. Error: "Boot File Not Written"

I can't turn on filevault in lion 10.7. The error returned is simply: "boot file not written". There is no other diagnostic info - help!

Open the Console application in your Utilities folder to examine log files.
How large is your user account folder and how much free space is on the drive? Have you repaired the hard drive and permissions?
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

Assigning folders and files to different physical disks OS X 10.9

My mid 2010 iMac 27 i7 quadcore, 32 GB memory has two 1 TB SSDs and several 2 to 3 TB 7200 / 5200 SATA, Firewire, LAN and USB external HDs. I would like to direct OS X 10.9 to use frequently accessed System data/images (boot, OS X, utilities and and their attendant folders and files) from SSD 1 and frequently used / accessed applications and their attendant folders and files on the second SSD 2. (I use Microsft Office Word and Excel frequently and also Windows 7 running on VMWare.) Then I would like to keep less frequently used applications and their attendant folders and files on the SATA 7200 external disk (USB 3.0 to 2.0), photos on a fourth external disk (firewire 800), music on a NAS (Raid 1, 1000Gb Ethernet), and movies on a fifth external HD (firewire 800). What I need to know is how to "assign" these various files to a physical disk. Please, I am not looking for opinions and/or guesses. I am looking for a strategy known to work and/or utilites known do set this up easily and correctly. Thanks in advance. BTW, I am a retired OS programmer and software/HW knowlegable. I have no Unix (or of course Apple OS X) programming experience, but have written and modified many other OSs. So one can be reasonably technical with me in their answers. Thanks again, Skip.

Hope this helps.

Disk verification stopped by user

My aunt has a G5 iMac with OS 10.4.11. A year ago, her password mysteriously changed, and when she tried to verify the disk using DU, before the verification finished it would say "stopped by user."
We reset the password with Single User Mode, and she could again verify her disk.
Now, suddenly she can't connect with the internet. Her DSL modem says it has sync and has Ethernet communication with the computer, but if she clicks Network in Profiler, it doesn't list Ethernet or Firewire or anything else.
If the modem says it has Ethernet communication, I suppose the iMac's Ethernet hardware works. What problem could interrupt disk verification and make the OS unaware of Ethernet and Firewire?

Two thing to try:PRAM reset and an SMU reset.
Also, using Disk Utility to check the disk:
1. Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.

How often is TDM data written to disk?

I'm using the Storage VIs to record data for some very-long-duration tests. How often is data actually written to disk?

Hi Ron,
TDM files are only written to disk once the Close Storage is called. Until that point, the TDM information is stored in memory.
Hope this helps!

My Time Capsule has stopped backing up. I have an Apple Time Capsule which backs up by wireless. For the last 3 days it has not backed up. I get this message: "The backup was not performed because an error occurred while copying files to the backup disk.

My Time Capsule has stopped backing up.
I have an Apple Time Capsule which backs up by wireless. For the last 3 days it has not backed up. I get this message:
"The backup was not performed because an error occurred while copying files to the backup disk."
I have gone into Mac Help and followed this down to stage 4:
under shared it lists my time capsule and my husband's iMac - both use the time machine but we have switched his off temporarily. Clicking on my Time capsule I get "Connected" and "Sharepoint" - I didn't have to enter connect or password
I don't understand stage 5: how and where do I select the disk or volume that contains Time Machine backups ? How do I know which it is? My disk utility lists 160.04 TOSHIBA MK... with sub-heading Macintosh HD. It also lists (with a "CD" icon) HL-DT-ST DVDRW GS22N
Under stage 6, how and where do I Locate your backup ? I try dragging my Time capsule from Finder to the Disk Utility side panel but it won't go. What is my computer's name?
Please someone help! I'm completely stumped.
Thanks,
Maggie
Mac Help says:
If you back up to a Time Capsule or network disk:
Open the Time Machine pane of System Preferences, and slide the switch to Off.
Open Time Machine preferences
Open Disk Utility, which is in the Utilities folder in the Applications folder.
Open Disk Utility
Make sure the Time Capsule or network disk is turned on and available.
Open a Finder window, select your Time Capsule or network disk in the Shared section of the sidebar, and click Connect. If necessary, enter your user name and password.
On the Time Capsule or network disk, select the disk or volume that contains Time Machine backups. Depending on how your Time Capsule is set up, there may be one or more disks or volumes.
Locate your backup, and drag it to the Disk Utility sidebar.You can identify your backup by looking for your computer’s name in the backup’s filename.
