subject: Data Loss During Upgradation To Mac Os X 10.5 Leopard And Mac Recovery Solution [print this page] In digital world, every other day, you can come around some new inventions and hence, upgradation of the older versions of the applications to newer ones is quite common. In order to upgrade your old application to a new one, you needn't have to do much. You just have to follow certain steps systematically and the rest will be done automatically by the application itself.
However, with some of the applications, this is not as smooth as it is said. While trying to upgrade to Mac OS X 10.5 Leopard, sometimes, you can only get an option of 'Erase and Install'. Even, the installation process gets interrupted with an error message and the hard drive becomes inaccessible thereafter. The situation can only be handled with any Mac recovery utility, as the drive carries your valuable data in it and you can't afford experimenting, which may even damage your data.
The error message in the above situation can be as below:
"You can not install Mac OS X 10.5 on this volume with out changing your installation settings.
Such a problem can be the outcome of a variety of reasons. One of the prime observation says that if you have used the tool 'TechTool Pro' in order to create an eDrive on the destination volume, then the problem as above usually happens with Mac OS X 10.5. Apart from this, the check process of the Leopard through the hard disk can cause such a problem. Mac OS X 10.5 makes a complete scan of the hard drive before it lists the drives & volumes in the destination window and if it fails, problem like the above surfaces.
Resolution:
The problem can be resolved by fixing the errors related to the hard disk. For this, you can use the tool Disk Utility, which is meant to verify and repair the storage device. Insert the Macintosh system installation disc and run Disk Utility from there to fix the errors in the hard disk.
However, at times, Disk Utility also fails and throws error messages such as: "Incorrect number of Extended Attributes (it should be 0 instead of [some numbers])"
If the Disk utility fails, the only way left is to Erase and make a fresh installation. In that case, you have to restore the lost data from the previously taken backup. In case, backup is not available, you can recover your data only through any Mac recovery software. These Mac recovery utilities are powerful enough to recover your data under any instance of data loss and along side, are easy to use.
Stellar Phoenix Macintosh Data recovery is a highly appreciated Mac recovery software which is capable of recovering any lost, deleted or formatted Mac data from almost all data loss situations. The software supports a number of different file types and works well with Mac OS X 10.3.9, 10.4, 10.6 and 10.5.
