At start, iPod software was developed only to work with Mac OS, but the present iPods can work with Mac OS X and Windows. But iPod software can get corrupted, thus forcing you to restore the iPod in question.

Since the iPod restoration process deletes all the data it contains, it becomes essential that you use your recent data backup to retrieve all the lost data. However, when backup cannot give the required results, you should use iPod Recovery Mac tools that are the commercial applications designed to recover and restore lost iPod contents.

When you turn on your iPod, you might observe an Apple logo or a sad face icon, followed by below error message on screen:“go to www.apple.com/support/ipod” If you click this link, it directs you to Apple support website.

Such behavior is usually exhibited by iPod if any of the below conditions exists:

iPod software is corrupted

Hardware issues

Try using these methods in order to resolve the above mentioned issues:

You should first try to reset your iPod several times. Try to force your iPod in Disk Mode. If you are able to do so, then it is a iPod software related issue. To troubleshoot such problems, you need to restore your iPod that will reinstall the iPod software and set your iPod to default settings with no data. Use your backup to retrieve lost iPod data.

Large Time Machine Backup: Error and Recovery

We know that in Mac OS X Snow leopard or Leopard there is a backup utility called Time Machine. This tool can take incremental backups of a single file, multiple files or even of whole system.

You can backup data to an internal hard drive or partitions as well as USB or FireWire connected external hard drive. Furthermore, the volume must be HFS Plus formatted with journaling enabled. It is recommended to always backup data on external hard drive to require Mac Recovery needs. It is because if internal hard drive faces some issues, you may require reformatting it. You might encounter similar error message with Time Machine:

This backup is too large for the backup volume. The backup requires 161061280.0 GB but only 270.4 GB are available. To select a larger volume, or make backup smaller by excluding files, open System Preferences and choose Time Machine”

You may also find all Time Machine backup being lost, apart from recent one. To solve the above issue, you can try following steps:

Time Machine drive requires about 2-3 times storage space of amount of data required to be backed up. So, you may need to replace it with a bigger Time Machine drive. If you are backing up on internal hard drive or partitions, reparation it and make a new partition of required amount of space.

Restore lost data from backup or commercial Data Recovery Mac applications (If backup fails, not updated or not available).

Re-index Spotlight. Click System Preferences->Spotlight->Privacy pane. You can then drag your Time Machine drive and hard drive to the list. In dock, right-click on Time Machine icon and click to Back Up Now. Drag the drives out of Privacy pane.

If problem persists, use Disk Utility to verify and repair your internal hard drive and Time Machine drive. It could be file system issues. Reformat the drives if Disk Utility can’t repair it and restore lost information using backup.

You then need to repair permissions. If you lose data and there is no valid or updated backup available, use Drive Recovery Mac applications and scan your drive. These are special tools designed to scan affected drive and safely recover lost data in any case of logical data loss.
