Note that format a hard drive doesn’t erase the data on this drive, only the data on the address tables, something like the marks of this data in partition table. Do not be panic, however, if you accidentally formatted a hard drive which has important data. A unformat hard drive software should be able to recover most, if not all, of the information on the hard drive. You can also buy unformat hard drive software that enables you to recover formatted hard drive by yourself.
At present UnFormat already appeared a little “lacks the ability to do what one would like”, used it resumed the formatting, the district method a little to be already obsolete after again, we might use many kinds of restore the software to carry on the data recovery, for instance used Derescue and Diskgetor and so on restores the software to be possible to facilitate carries on the data recovery work. Moreover DOS also provided a miror order to use in recording the current floppy disk’s information, after formatted or the deletion restoration use, this method was also quite effective. Under the DOS high edition condition, the formatting operated format to establish under the default state has used in resuming formatted the floppy disk information, in fact was floppy disk’s DOS boot-sector, the fat district table and directory lists all contents duplicates in floppy disk’s final several sectors (because of the following sector very little use), but in the data area’s content simply has not changed. We knew that has good tool UnFormat in the DOS time, it may restore the floppy disk which eliminates by the Format order. If the user were uses the Format order under DOS to format by mistake some district, might use this order to try. However UnFormat can only restore the local hard disk and the software driver, but cannot restore the network driver. The UnFormat order except the above counter-formatted function, it can also repair and on the establishment hard disk driver’s damage district table.
