Hello: if anyone could assist me please let me know. I am running Logic Pro 8 on a Mac G4 (yes, really....with leopard OS) I have leopard and logic 8 installed on the main system drive. In addition I bought a 7200 RPM 750 GB hard drive to record all of my files to. I have no problem recording, everything seems to track just fine. When I go to open the files in logic, I get errors, the waveforms do not load, and nothing plays. If I record to my system disk, everything is ok. The system records and plays back just fine. The problem there is I DON'T want to record to the system disk!

Based on that, do you know of a misconfiguration of some sort I have? If you need more information please let me know.

P.S. I can save and open any other file to this drive. For example I can use text edit and save a document to the 2nd drive. And then reopen it just fine.

Is you second drive USB? Only firewire drives are recommended for recording.. generally. I might be wrong in your situation, not absolutely sure. good luck.

Sorry, I didn't specify. Both drives are internal.

Take a look at the disk info in the disk utility, make sure that the drive is formatted for OSX.

What's the make of the hard drive precisely ?

Next, I'd look into the way it's formatted as gdoubleyou wrote.

Last thing to try is to use an external enclosure and see if it does the same thing.

I use two internal drives on my G5 (understood, different proc, different HDD interface) with Logic Studio and Leopard and do not have any issue with the process you describe. I have my second drive partitioned into different partitions to reduce the cluster size and also segregate my work (audio/song files, audio/soundtrack files, video, masters, MP3s, Temp Files) and record all my audio directly to the second disc.

I'd make sure (as pointed out by both lepetitmartiean and gdoubleyou) that the drive is formatted correctly (Mac OS X, journaled recommended for Leopard, but not required) and that you have repaired it in Disk Utility.

What are the specific errors you get in Logic when you open projects with the files recorded (presumably also in Logic) on the second drive? Is it "Missing Audio Files" or some other more cryptic error?

that's definitely a head scratcher. Post back and lets see if we can figure this one out collectively...

peace.

Caveat: I've never messed with Logic, but these things are pretty universal:
Will the recording created on your 750gig drive work if you copy it to your system HD? Will the recording you made on your system HD work if you copy it to the 750? (restart Logic after copying) Did you try recording a simple single audio line in with no plug-ins, effects, bells, whistles, etc? Leopard is kind of a resource pig, any programs or 'processes' you can turn off? Memory all maxed out? Got plenty of empty space on your system HD (a couple gigs at least - Leopard, and dang near everything else, uses system disk space for 'temporary files')? You might just be pushing the limits of your G4's capabilities and/or the read-write bus for your 2nd drive is a smidgen too slow for your askings. Maybe it'd help to plug the 750 into the other IDE ribbon (i.e. the other I/O bus) inside your G4 (assuming there IS another IDE ribbon for connecting internal drives)? Might be you'll just have to live with the irritation of disk-to-disk file-copying-as-needed until your next Mac, but DO be cheerful! You DO have a working rig! (grins)

Thanks for the help. I'll be busy most of the day, but later on I will gather the requested info for everyone. And maybe we'll come up with something

Ok, here is some info: Some recordings were originally done on an eMac which operated normally within that machine. I firewired the emac and G4 together and moved them to my new audio drive on the G4. It is there they do not open. If I copy them over to the main system drive on the G4 they operate normally. If I copy them from the system drive to the audio drive on the G4, they seem to copy over to the drive just fine. But, they will not open in logic from there. When I open logic and then try to open it from the audio drive I get the error. "The document "1RealMIXEDSORTOF" could not be opened. If I then try to move the file I copied to the audio drive back to the system drive I get the error: "The finder cannot complete the operation because some data in "1 Real" could not be read or written. (Error code -36)

Ok now about the disks:

System Disk
40 GB
Format: Mac OS Extended (Journaled)
Available space: 23.75GB

Sharing and Permissions
system read and write
admin: read and write
everyone: read only

Audio Disk: *Note, I wrong before the disk is 320GB, not 750GB
320GB capacity
Format: Mac OS Extended (Journaled)
Available space: 295.15 GB

Sharing and Permissions:
JaridX (Me): read and write
staff: read and write
everyone: read only

Drive is a Western Digital Cavier SE 320GB PATA

Any more info needed? Let me know!

A (not so) stupid but maybe useful idea:

Select in finder the naughty HD, ask for the informations (command-I) go down the window to the permissions, and check "ignore the permissions on this volume".

Do this on data only drives, NOT on system drives. At least it'll leave out the permissions issues.
