Re: How to fix bad sectors or clusters on hard drive ?
G'Day Folks,
Took me awhile to sort out my registration so I could post on this Thread, alas I now can.
I read through all the comments on repairing HDD and would say this:
1. If a HDD has a mechanical failure, i.e. makes a clunking or clanking type noise (similar to a knocking noise) while you are attempting to use it,
or it does not power on or spin at all, then the HDD most likely is "Kaput"
2. If however the HDD is recognized by the BIOS and it does spin, then there is hope.
I have used
Spinrite 5 and 6 from the Steve Gibson site as well as the
HDD REgenerator both v1.51 and v1.71 from Dmitriy Primochenko many a time with success. The URL's I have provided are the defaults for their location.
Yes HDD's can be repaired and Bad Sectors can be recovered ! - It just takes a long time to do so and may not be economical to do so.
When I say a long time I mean an 80GB HDD can take a week or more depending on the number of bad sectors found that need to be recovered.
3. another point to remember, is that after the repair, and can be attempted before, is to download the "Low Level Formatter" from the HDD's manufacturers web site and load this on a bootable media (HDD, USB or CD or DVD) to be able to test and perform the low level format, and then run the fdisk to see if the failed HDD can accept partitioning , followed by a re-boot and then attempt a normal format with the /u (unconditional) option.
E.G. at the cmd prompt type format ?: /u (replace the ? with the drive letter on which the HDD is mounted)
If it performs and does complete the tasks in item 3, which is good and you have your HDD back.
If attempts in item 3 fail, then you can try the Spinrite or the HDD Regenerators, as the sectors must be in working order before any partitioning or formating can be applied.
I am currently running such a repair on an 80GB HDD (Seagate) with the older HDD Regenerator v1.51. It has so far run for 3+ days (continuously) and is at the 2352Mb of the 80000 (
80GB) and has so far discovered and repaired 29428 bad sectors.
This is not the first time I have used these utilities to repair HDD, this one is the 63rd HDD with the previous attempts being successful with 51 out of the 62 attempts.
In closing, I will say to all the sceptics that they are wrong and HDD's can be repaired, if you have the know-how and patients to do so.
BTW: I also do forensic file recoveries from HDD's and recently recovered a file that the User had deleted 9 month ago.
I must try the
Flobo HDD Bad Sector Repair 1.5
