Where to Begin....

#1 Post by jackeebleu »

So a few weeks ago, I started receiving errors like this on my Mac's external USB 3GB drive, it stores all my music and photos.

Immediately, I ran Disk Utility which found myriad permission errors but advised all was well with the drive. Alerts kept firing until one day the drive just wouldn't mount at all. I stumbled across Testdisk and was advised that run if via terminal. Did that. After a few hours, received an alert that there was 0 space on my boot drive, even though I launched it from another external 1.5TB drive. I delete the 30GB log file, and rerun analyze with no log file. I get this:

4 days later, I receive the following:

If the partitions can't be recovered, what do/can I do now?

Some Info about a diagnose on Mac;

Please not: pdisk is not compatible to Intel-Mac.
If you receive read errors, you should clone your disk.
But you can try PhotoRec to recover yoiur photos and music.

If you don't like to recover unnecessary files, you can use the menu File Opt in Photorec.
Pressing s desects all filte types.
So you can select only those file typed where you which to recover.

I have no idea, what kind of file system you have had before.
Has it been FAT32 or HFS+?
If sectors are physically bad, your disk should be replaced.

It was shipped HFS+. I've formatted an old laptop as Ubuntu and am running the tool again. It's moving a ton faster. I'll see what it does under this version.
