If this information is corrupted any how or it becomes unreadable, the floppy disk causes such reading error messages. It may be due to physical or logical corruption of the first sector of the disk.
The Logical corruption includes the cases when the information of the first sector of the floppy is changed, there occurs any logical bad sector or the DBR of the floppy is corrupted due to any other reason.
The Physical corruption is supposed to take place in case of, if there are physical bad sectors (means the sector 1 is physically damaged) on the first sector of the floppy disk. The problem becomes more serious when you find that floppy is having more than one bad sector in track 0.
How to recover
As we have learnt both the causes of corruption I hope now you are able to understand the problem. It is not a very difficult thing to recover the data from logical corruption however the recovery from the physical corruption needs slightly more efforts to do.
Method – 1
Store the boot image of any fresh floppy
If the problem is logical, now we understand that how can we recover the data. What we need to do is just to get the appropriate Boot record from another floppy of same size and capacity and to paste it to the first sector of the unreadable floppy. Though the problem was created due to the bad boot record, it should work now.
There are two steps involved in this procedure by following which we are recovering our data from an unreadable floppy:
- Making the image of DOS Boot Record of a good floppy
- Pasting the boot image to the first sector of unreadable floppy
