Copy files between pcs - checksum error

Scenario:
- Two PCs (A and B) in a small LAN.
- Computer A runs a NFS and a FTP server. I can transfer file from A to B mounting the nfs exported directories or downloading them via FTP.
- The files can reside in ext3 or xfs partitions, on different drives, in A and they are being copied to B in ext3 or xfs partitions, again on different drives.
- Drives and filesystems are healthy (knock on wood).
I download a given file along with its checksum file (md5 or sfv format), from internet on A: the checksum check using cfv (tried even md5sum) says it's allright.
Then I copy the file on B (via FTP or NFS - it doesn't matter), check it again and I have an error ("bad crc"). Sometimes for the file I download, there's a torrent: if I use the torrent file and check the integrity of the downloaded file (with ktorrent or gtorrentviewer), I find that there's a missing piece.
The above happens random, not always and not with all files.
A really strange thing is that, if I mount A's exported directory in B and if I run the checksum check from B, I also get an error (as said above, if I check the file directly on A, it's good).
I can't remember when this started - in your opinion, where should I look for solving this?

I dont really understand the torrent part of the story.
Sorry - I wasn't that much clear and my english doesn't help
A torrent file can be used for an integrity check of the file: not only it reports if the checksum is right or wrong, but - in this latter case - it can tell you that there are missing pieces in the file and how many.
Hmm and it sounds like pc B isnt that healthy
I checked for filesystem sanity in both PCs, and I also run the Seagate diagnostic tool on both of them. The chance that 4 hard disk are failing at the same time in the same PC is negligible. Anyway, I'm open to suggestions here - maybe it's an hardware issue, but I don't think it's related to the hard disks.
what if you try it with an usb stick ??
I'll try copying files to an external drive and to another PC - thanks for the idea
try to check the size of the file you copy if there are both equal.
They aren't - otherwise I won't get that checksum error. The difference is usually small, though - only a few kbytes: it seems to me that the copy process doesn't end properly.

Permissions problem copying files between two Macs

I've run into a strange problem when trying to copy files between two networked Macs. Some background facts: We have two Macs at home each with three accounts. Two of the accounts are regular user accounts (my wife's and mine, call them "K" and "B" for short) and the third is an administrator account (we'll call it "A"). I have a .Mac account, which I use to sync between the two Macs. The other accounts do not. The user accounts B & K were initially set up on the second Mac via the Migration Assistant, copying over files and settings. The administrator account was not.
The problem I've run into is that if I am logged in as either user B or K on the local Mac, connect to the remote Mac as the corresponding user, and try to copy files into a folder owned by that same user on the remote Mac, I get a series of three dialog boxes with error messages:
1) "You may need to enter the name and password for an administrator on this computer to change the item named ..." (stop/continue)
2) "The item ... contains one or more items you do not have permission to read. Do you want to copy the items you are allowed to read?" (stop/continue)
3) "The operation cannot be completed because you do not have sufficient privileges for some of the items."
If I go all the way through this hitting continue / OK on each, what shows up on the remote computer at the end is an empty file with the name and filetype of the local file that I was trying to copy, but of zero length.
This only happens when I'm copying from (local.B -> remote.B) or (local.K -> remote.K). It does not happen if I try any of the other pairwise combinations (assuming that I've authenticated properly): (local.B -> remote.K or remote.A), (local.K -> remote.B or remote.A), (local.A -> remote.B, remote.K or remote.A). It happens regardless of which Mac is local and which is remote.
I'm a little baffled. I've tried to search for this on Apple Discussions and other forums, but either haven't been using the right keywords or am coming up blank.
Anyone have any suggestions?
Thanks,
Bob

borbye is correct that this will remedy the problem but there is a way to do it and have your account work. after changing the user UID and group UID to 501 you will have to restart. then when you log on your home folder will still be your default but you will not have any access. Since you are still an admin you can change that. right click on the home folder and select get info click arrow for sharing and permissions. Your old UID account will show up as _unknown delete this user and add your user to it giving yourself read and write privilege. click on the cog on the bottom and select apply to enclosed items. A warning box will appear stating that this process cannot be undone do you wish to proceed? click yes and a status bar will come up. once the bar is gone the process is complete. since you didn't have access to your home folder you cannot save your settings, this is a good thing since your account will not look remotely the same as yours most likely. all you have to do now is logout and then back in. Your account will look as it did before the change with all the access settings and so forth as before the change... minus some permissions due to the overwrite. It's a minor repair to the permissions to some shares considering you will be able to now move files to and these shares without the permissions alert that only creates a 4kb file instead of the real thing. Takes 5 minutes at most. Have fun.

Back To My Mac: why can't I copy files between Macs?

I use Back To My Mac to connect between a Mac Book Pro and Mac Pro. These two machines have the same home directory name, but different passwords. My home network is on an Apple Airport Extreme.
A recent, persistent bug is causing havoc when I try to copy files between computers. Here is what happens:
1. I connect to the Mac Pro remotely from the MBP, using my Apple ID credentials.
2. Using a finder window on my Mac Book Pro, I try to copy a file TO the Mac Pro desktop that I'm certain doesn't already exist there. A "Preparing to copy" window appears.
3. After a few moments, a window appears: "Finder wants to make changes. Type your password to allow this." Again, I've already entered my Apple ID to connect to the Mac Pro. This window requires my Mac Book Pro sign-in in order to continue.
4. The next message is 'A newer item named “FileName.pdf” already exists in this location. Do you want to replace it with the older one you’re moving?'
Here are the results of my options from this dialog:
>>If I choose 'Keep Both Files':
-- A progress window appears (saying something like "copying 0 of 108 kb", but without any progress bar movement). I click the X button to stop the transfer, the progress window changes to "stopping" status, but remains on the screen for several minutes. My Mac Pro is unresponsive/unreachable via BTMM during this time.
-- After several minutes, the file transfer progress window disappears and my Mac Pro becomes available again via BTMM. There are now several THOUSAND numbered copies of the original. Each is 0 kb in size.
>>If I choose 'Replace':
-- A progress window appears, quickly followed by this message: 'The operation can’t be completed because an item with the name “” already exists.' The message appears exactly as written, without the filename between the quotes.
-- A file with the same name as the one I tried to copy over is now on the Mac Pro desktop, but it is 0 kb in size.
I'm lost -- not sure if this is a permissions issue, a problem w/ BTMM, or something else. Any input, advice, questions, etc. are very welcome.
Thanks

I'm having the exact same issue, did you find a solution. It's annoying!

Copy Files Between Two Unix Computers

Hi,
I am trying to write a piece of code that will copy bunch of files from one Unix computer on to another Unix computer. On windows it seems to be pretty straight but on Unix I am trying to understand best way of copying the files. I don't have much expertise in Unix.
Is using FTP the only option for Unix?
I am not able to create a FILE object by referring to a file on some other Unix box? I tried new File("//unixbox2/temp/123.txt");
Please let me know the different ways to copy files between Unix computers.
Thanks

Copy files between 2 USB hard drives.

I am trying to copy files between 2 USB hard drives. I can copy to the clipboard but it won't let me paste in the other drive. Any ideas?

Check if the destination drive is NTFS. If it is then you only have "Read Only Permission". You need to reformat the drive to "FAT" or Mac OS X Extendend (journaled)" using Disk Utility.
Select the Drive on the Desktop and Press "Command" - "i"

Copying files between Iphone and PC over 3G-connection?

Hi,
Is there any application for copying files between PC and Iphone using a 3G or Edge connection? I'm using Jaadu VNC client on my Iphone but it has no functions for file transfers (as far as I know).
Thanks for any hints!

No. I don't believe that would be allowed with the SDK. You could always email them to yourself.

Leopard / Bootcamp / Vista / Copy Files Between Mac OS X and Windows

On the apple page it says I can copy files from mac to windows?
"Copy Files Between Mac OS X and Windows
Copy, open, modify, or delete files in Mac OS X that you saved to your Windows partition. Leopard understands the Windows FAT32 disk format."
I tried installing Vista in bootcamp, but it says I cannot install in FAT32? So i format it to NTFS.
So here's my question, Can i still copy files between mac and pc, if I format into NTFS or am using vista?
Thanks

I am quite a simple soul really and very easily pleased.
All I seek is a partition of some sort that I can save all my created work to - whether in XP Pro or OS X 10.5. But it has to be a large partition - probably a single partition on a large drive.
It would be sweeter still for Spotlight to do what it does (and it does on a FAT partition) and sweeter still for Time Machine to be very user friendly and do what it presently does not do and include created files into the TM.
Now that really would be very pleasant. Very pleasant indeed.

Can no longer move or copy files between drives (not a newbie issue!)

Copying and moving files between internal and external devices, and external to external devices is no longer working.
*For the first time in my life, I get a "Circle with a Bar through it" when attempting to move or copy files.*
This doesn't happen between the two internal drives at all (though I'm worried it might start). It happens between two HFS+J devices as well as HFS+J and FAT32 devices. I can delete files, create folders, and in some instances where things are acting funny, copy to, but not from the device. A noticed side effect that is now happening is that I can no longer move drive icons (CDs, DVDs, HDs) to their upper-right hand corner position on the desktop, if they didn't start there. They don't drop there, just staying where they originally sat (under a list of desktop shortcuts and files). It does not matter if the drives are USB or Firewire, and this never happened previous to about a month ago.
I have done all the basic stuff -- verify/repair drives, reboot multiple times, mount & dismount, change connection ports, backed up-reformatted-and restored the smallest drive, fixed preferences (not at all relevant), Disk Warrior repair the devices, set all permissions to R/W, check all device related infos, researched on-line for a week... Nothing. I have even taken the devices to PCs, where they work perfectly, and as expected.
This issue is apparently either a corruption, or a bug induced by Software Update, in the part of the system that handles files and file structures, or possibly the _USB and Firewire_ interfaces.
I just need to know where all those relevant parts are in the system folders, so I can attempt to restore them from a backup previous to the last "Software Update," (to be sure. And to bring this one step closer to being solved).
A system restore really is not an option, as that would require nearly two weeks of re-tweaking everything from the system to every piece of software included (updating the system about 10 times via software update, reinstalling 90% of the actual software packages... and then updating those multiple times, looking-up all the serials that get killed, etc.)
I have to correct this fast, as we need to move the files from the work drives to the archive drives before we run out of room. So any help would be very appreciated... even if you only know where a few of the system components are located (it just might be one of those, causing the issue).
---TIA

{The last link in this post is most relevant, except for your recent finding.}
The reference was to the User permissions, per each; as when these
become corrupted, the simple 'repair disk permissions' and other
basic duties do not find an error with them. That is because there is
nothing really wrong with them from that standpoint.
Another odd error can happen if one is resizing partitions in an Intel
based Mac, and also if one has or had a BootCamp partition and
wanted to reclaim space. But not always. Thankfully, the only time
I tried Windows on a Mac, the media install disc was corrupted so
it just didn't happen. That was Virtual PC and Windows on PPC.
Tiger brought with it the ability to non-destructively resize partitions.
However, it was not thought to be successful in non-Intel based Macs.
The discussion on that matter came up a few years ago, so someone
has undoubtably tried that in a PPC and reported findings online.
When file sharing between user-account created content runs amok,
then the system(s) will not allow the content to be moved or shared.
So, if any shared user-account created content (including drives
initialized or handled without permissions ignored, clones wrong,
etc) are not the problem, then how does one explain these wrong
ful action circles-with-lines, or action disallowed warning symbols?
There must be a simpler answer. Do you have cats which have
access to your computers in the off-hours? They do keyboard.
Some have been thought to have technical skills outside of the
usual coy and cute play-acting people think they are limited to.
I'm sticking to the cats theory for now; the time is 3:21AM here
and I only am up to get a drink and look outside at +5°F. calm.

Problem using scp to copy files between Macs

I've been trying to copy a folder hierarchy containing a slew of icon files between two of my Macs. Using scp has proven to be futile.
The command line I'm using is
scp -r -p -C -E [email protected]:/Icons /Icons
After a number of files are copied I receive the following error message on a file and all thereafter:
./icons/Agrapha-Christmas/Boxes: Too many open files
More specifically the "too many open files" message.
I am using Tiger 10.4.7
What am I doing wrong here?

One more piece of information. I ran scp with the verbose switch and have attached a portion of the feedback showing successfull copies followed by the error which occurs on all subsequent files:

Copy file between servers, passing on firewall

I'm try copy a file between servers with Windows NT. I mapping the target server to drive X and test copying a file in windows explorer and command window and the files copy is OK. But if I try with a java class don't.
I'm try with FileInputStream (read) and FileOutputStream (write) but don't. I have use the Runtime.exec() for execute a DOS command but don't("cmd.exe /c copy c:\myfile.txt x:\"). this second showme a message "username incorrect or bad password", but the same sentence I run in a command window and the copy is OK!
What can I do?

Hi,
try to use HTTP for the transfer between
the two servers. Normally You can pass the
firewall using HTTP (like browsers do).
Therefor use classes in the java.net packages.

Copying file between non SAP and SAP server in background

Hi,
I have written a program to copy files from a non SAP server to our SAP server which works when running in the foreground.
When I try to run this program in the background, I get the following error ...
Control Framework: Fatal error - GUI cannot be reached
Can anyone tell me how to do this in the background.
Thanks.

Hello,
seems that you use some customer controls in your program. These controls are bound to a dynpro - and that doesn't work in background.
You could try to avoid this and just do the copy without using controls.

'Finder wants to make changes' when copying files between two Macs

Hey all,
I've read a few versions of this problem on the forums here but haven't tracked down a solution.
I have two Macs on the same network – I recently got a second-hand Mac Pro, and my Macbook Air. The computers are both on the network and can browse their respective folders and the like, but when I go to copy or sync files between the computers, I get a file permission issue.
Finder on either computer prompts: 'Finder wants to make changes. Enter your password'. At the same time a corrupted version of the file copies to the other computer but with 0 bytes that doesn't open...
Has anyone solved this issue before – it'd be greatly appreciated to hear any approaches!

On the laptop I got 513
Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
This time you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.
Boot into Recovery. When the OS X Utilities screen appears, select

Can no longer copy files between internal drives or from burned DVD's

This just started today as far as I can tell. We have 4 dual 2.7GHz G5's running 10.4.4. Two of them seem to work as normal. The other two won't let me drag/copy files from one of the internal drives to the desktop or the other internal.
We have two internal drives, the one with OSX on it that works fine as in I can copy/drag files to the other internal drive (labeled "AV") or to the desktop. The AV drive won't let me copy/drag any files to the desktop or the other internal, I get the circle with a line through it. Also when I burn a DVD I can't copy/drag the files anywhere on any drive. If I put a previously burned disk (burned prior to today) in I can copy it fine to any drive.
I have verified/repaired all disks, repaired permissions, and checked read&write permissions.
Any help?

OK, I figured it out (I'll admit to being a Mac n00b). I was using DVD+R's. So the act of trying to copy files from a DVD+R (even though it was burned in the same G5) changes something in the drives so nothing on them will copy.
Ejecting the DVD+R and restarting without the disk in it got it back to normal. The problem was reproduced when I tried the DVD+R again (just to confirm the issue and solution). Again a restart fixed it.
Moral of the story, don't use DVD+R in Macs even though they can burn to them.
Anyway, if anything hope this post can help other n00bies.
G5 Mac OS X (10.4.4)

Problem with copying files between OS 9 to OS 10.4.9

We have updated 2 computers to 10.4.9 after som minor problems its working fine the only problem we still have is that we cannot copy files from our older Mac running OS 9.2.2 to the macs running 10.4.9 if we copy 1 file its working when we want to copy a folder or more files the connection got lost we get a message the connection with the file server unexpectedly broken. We also have a Xserve running OS 10.4.6 coping files to the Xserve is not a problem and is running just fine.
We can copy files or take files from the OS 10.4.9 macs to the Mac with OS 9.2.2 this is no problem just copying a bit slower then to the Xserve.
All the computers are in a netwerk with cat5 cables and was working just fine before the updates to 10.4.9

Welcome to Apple Discussions!
Copying from 9 to 10.4.9 is not recommended unless Mac OS X is under control of the copying. Mac OS 9 has no familiarity with the file permissions of Mac OS X and thus if you make a mistake, you could seriously damage the permissions of Mac OS X. Others have found problems transferring from 9 to 10.4.9 where not with prior versions of Mac OS X. I say it is about time, because of the risks involved but for others their workflow depends on it they are having to relearn how to go the other direction. I've found if the risk is not taken account for, you can make Mac OS X unbootable. My suggestion is to either do all your networking and file transfer for Mac OS X from Mac OS X, or upgrade the software you have to Mac OS X native equivalent software. See my FAQ on migrating to X*:
