I was wondering if there is an application that can tell us (in an easily understandable way...like in a chart) how healthy our hard disc is. If the boot sector is healthy...etc.
If you click on dash and then type disc, you will get a disc management tool, called Disk Utility, that shows you that and more.
Disk utility is tools for formating, partitioning, and manage harddrive or removable storage such flash drive/disk drive.
Utility to check how fast your storage to read and write data, you can use this utility to compare a performance form one to another.
Smart data would check and show us the disk healty using attribute and its assessement. using his utility we can llook after harddrive temperature and bad sectors.
8.Delete Partition This action is for delete a partition table.
The best info about Disc Utility in my opinion can be found here
You can always give GSmartControl from the repositories a spin. It'll run both short & long tests built into the drive, also displays SMART info.
