MAC OS 10 reformat and reinstall newest MAC OS and then reverted back to Mac OS 10 again, any chance of recovering the data back?
What software is good to recover formatted MAC?

Thank you.

the problem is if the data has been written back to many times
your go over the free space
but i dont think that would happen just yet

if you want to recovery deleted files not the os of the system



best program i found for macs is nucleus data recovery

Hi, Junior

The two common versions of Mac file systems (or volume formats) are standard HFS and Mac OS Extended (or HFS+).

HFS is best for small volumes or those that may be used on older systems (before OS8.1). Mac OS Extended is best for larger volumes as long as they will not be used on older systems. Mac OS 10.3 brought a new iteration of HFS+ called HFSX. HFSX is basically the same as HFS+, but it allows for new file system features to be specified. One such feature is case sensitive file/folder names. The file names "fname", "Fname" and "FNAME" would all refer to the same file in HFS/HFS+, but they would refer to different files in HFSX if the case sensitive feature was turned on.


Standard HFS:
Compatible with all Mac OS versions
File names limited to 31 characters
File sizes limited to 2GB
Large volumes with small files waste a lot of space.

Mac OS Extended (HFS+):
Compatible with Mac OS8.1 and later
255 character Unicode file names
No file size limit
Less wasted space
Mac OS Extended (HFSX):
New in OS X 10.3
Purpose is to allow extended features that will not be compatible with HFS+
One major feature is to allow case sensitive file names

You can try some data recovery software aiming at Mac OS. It is an easy case which logical data recovery software can do.

Good luck

Regards

Laura
