Upgraded to 10.7 (Lion) and trying to copy about 300 GB of files from 1 external drive to another external drive and Finder continues to crash.
I've tried copying smaller chunks and it works fine up to about 9 GB, when it seems to crash.. forcing me to restart the copy process.
Is there a limit to the amount of data that I can copy in a single batch?
MacBook Pro, Mac OS X (10.7)
I'm having the same problem. Really frustrating. I read that someone noticed a difference from drag-n-drop to cmd+c and cmd+v, but it crashed anyway. The disk i am copying from has 181GB out of 500GB free, and the disk i am copying to has about 1.5TB free. Even the system disk has over 100GB free.
Really hope someone can help with this asap.
Think i found out the issure. One of the disks are NTFS, so needed to install a program so the mac gets all rights to it. Works fine now 🙂
What was it you installed? Would be nice to know this information.
Paragon NTFS for MAC 9
Found MacFuse and NTFS-3G for free.
MacFuse/NTFS-3g work, but it can be flakey. (Stops working randomly, perhaps after Apple updates. Reinstall usually fixes it.) Paragon has been rock solid.
However, if you were able to copy ANY files, than this was not the issue. This means that Apple's NTFS drivers have changed for the worse. Reading from an NTFS drive but writing to HFS also should not matter, reglardless of this driver.
I couldn't copy large files to my iMac since upgrading to Lion either. My Mac would always crash eventually, requiring a hard restart everytime.
The problem for me was my Intego Virusbarrier installation. Removing this solved my copying grief.
I hope this helps someone!
I rountinely backup large chunks of data from my Mac Pro to two external OWC VoyagerQ Firewire hard drives (800). When I say large I mean anywhere from 50GBs to 500GBs at a time. Under 10.2-10.6 I could start one copy and then the second, simple Finder copies mind you, and after the interminable file counting BOTH copies would proceed SIMULTANEOUSLY. Made it as simple as pie to walk away and come back knowing my data was now in three places.
Under LION the same process has become hopeless. Following the same procedures above now results in the FIRST copy having to complete BEFORE the SECOND copy can commence. Are you kidding me? A doubling of the time I have to spend backing things up? Before Apple faults my setup or something, I have five VoyagerQs and three FireWire 800 ports, and have tried the two backup drives chained, on separate FW channels, even with one inernal and one external and the same thing happens. I suspect that this is related to Thunder^^^^ and is something APPLE has got to fix fast or a lot of folks are going back to 10.6. Be interesting to see how the Mothership responds. Kill the messenger is most likely.
Finder crashes while copying many files.
