Help: Managing Apple Music Files


What is the best practices for the following scenario:

I have backed up my lossless Apple music files from a dedicated external 1GB Hard Drive (dedicated HD) to another 1GB HD (backup HD).

I now want to import music to my laptop PC from the back up HD but want to compress the files (to 256 or 320kbps AAC??).

What compression do you think I should use? These files will be used to import music to my Iphone and other Ipods since I use my laptop to manage my Iphone syncs. I have around 600 GB of losslees music on my HD's but only want to use 100 gigs or less on my laptop and will filter out about one fourth of these files in the transfer (600GB minus 150GB= 450GB to compress and transfer). I will also listen to these files on my laptop while traveling etc...

What is the best way to do this? I was told that I would need to compress these files while still on the the back up HD and then import the compressed files to my laptop. Then erase the compressed files and go back and back up the loss less files from the dedicated HD.

By the way, I am using Carbon Copy Cloner to manage back ups and Mac Drive 8 to enable the PC laptop to manage the MAC formatting of my hard drives… are these the best software for these tasks?

Thanks, Doug

Mozartrules - I agree that converting in ITunes might be the simplest but how do we import the files? What about leaving files where they are and just give Itunes on the laptop wireless (or network cable) access to them by sharing backup drive. Itunes is perhaps slower than wireless anyway. According to my calculations wireless transfer of 650GB would take at least 32 hours but this amount of ALAC data is equal to about 2000 CDs. 32hrs=1920min so it comes to about minute per CD for Itunes to convert - sounds about right.

Max on the Mac would convert faster and transfer would take many times less since data is compressed about 4-5 times (remaining space on external hard drive can be used for temporary storage). Better yet make MAX or Itunes to compress it and deliver to different location that would be laptop's shared drive over wireless. I would use 256kbs with VBR.
Lokie - transfering 600GB to laptop is not the best approach. Connecting USB drive to laptop might not work since formats are different. Use Itunes on the Mac with output pointing to shared directory on the laptop (wireless or Ethernet). That way you transfer much smaller - compressed data.
Loki - OK 450GB of uncompressed music. All I'm saying is to compress it on the MAC pointing ITunes output to Laptop's directory. You need to make laptop visible to MAC allowing particular directory to be shared - so that MAC can write to it. If you connect them with Ethernet cable be sure that it is the right one (not a patch cable) since receive and transmit lines have to be crossed.

Hard Disks, as I understand it, unless both have FAT32 (a really bad format) MAC's external disk has MAC Extended format while your PC laptop has NTFS. Both are nice (since journaled) but AFAIK PC cannot read MAC drive directly (but there are applications for that like MACDrive8)
Use MAX. It can translate any format to any format - and it is free. It works on Mac only. I believe that you can run it in batch mode since I was able to convert a lot of files from FLAC to ALAC by selecting all of them, right click and "Open with .. Max".

I' also using Carbon Copy and it works great so far.
