How to recover data from corrupted external hard disk?
How to recover data from corrupted external hard disk? when I am connecting hard disk to laptop its asking for format & showing I/O device error while trying to open it.
If the hard drive is in an external enclosure, remove the drive and mount it in a different enclosure (you can buy empty hard drive enclosures from Amazon or any large PC store).
If still the drive is not accessible, it has failed and the only way data can be recovered from it is to send it to a data recovery specialist, but the cost will be high.
You should never rely on just a single hard drive for storing your data. You need to keep the data backed up on another hard drive or on optical discs.
