Windows 7: pc froze and now running good after chkdsk

I would run disk check at least once a week on that drive with both boxes checked or with the /r command. Do that for a couple months, and if any errors show up or the bad sectors grow beyond 76 KB, start to worry. If it runs fine, then maybe it just had some bad sectors to sort out.

the thing is once i start to put data on the drive then at some point it will find more errors
this is basically how it did it last time it reported there was no bad sectors
but if i could do as that small tut says in that post maybe it would block me from using those bad sectors forever that way ill never get those errors by putting data on the drive
also if you would see if you could help with this
dvd drive & HDD on same IDE install windows & ect

You cannot avoid bad sectors if they are accumulating. Accumulation implies a mechanical problem with the head reading the disk and possibly clobbering sectors in a physical manner. NTFS.com HARD DRIVES. Hard Disk Drive Basics.

so your saying that even with out putting data on the drive & leaving it as is while using it will eventually still give all those errors for my sake im hoping your wrong ill leave it as is and con. checking the disk here & there

I am saying that if the bad sectors accumulate, there is nothing you can do to avoid the drive going bad. I also said earlier that it could just be you had some bad sectors that needed to be set aside. The only way to know which of the two cases it is would be to run the disk checks once a week for the next two months to see whether the size of the bad sectors increases.

ok im fine doing the test for a few weeks if not 2-3 months & if this drives test comes back every time without errors & ect & no problems from me not loading data on it will that be repairable im thinking it should be there got to be away of blocking me from using those bad sectors
if a cd/dvd is scratched does it not still play audio/video from it

NTFS actually re-allocates the drive on a regular basis. Hard drives come with extra sectors because bad sectors always occur on hard disks during production. When one does a low level format, the disk is re-allocated in the good spare sectors and the bad sectors are removed from the allocation table. NTFS does some of this on the fly as the operating system runs, but if it is unable to do so cleanly, Windows throws errors into the event viewer logs recommending that the user run a disk check. Many users do not know to check these logs, and the system suffers as a result of corrupted data and hard disk errors.

Quote:
The fourth stage of CHKDSK is only invoked if the /R switch is used. /R is used to locate bad sectors in the volume's free space. When /R is used, CHKDSK attempts to read every sector on the volume to confirm that the sector is usable. Sectors associated with metadata are read during the natural course of running CHKDSK even when /R is not used. Sectors associated with user data are read during earlier phases of CHKDSK provided /R is specified. When an unreadable sector is located, NTFS will add the cluster containing that sector to its list of bad clusters and, if the cluster was in use, allocate a new cluster to do the job of the old. If a fault tolerant disk driver is being used, data is recovered and written to the newly allocated cluster. Otherwise, the new cluster is filled with a pattern of 0xFF bytes. When NTFS encounters unreadable sectors during the course of normal operation, it will also remap them in the same way. Thus, the /R switch is usually not essential, but it can be used as a convenient mechanism for scanning the entire volume if a disk is suspected of having bad sectors.
Taken from An explanation of CHKDSK and the new /C and /I switches, which I would recommend as further reading.



Also, Flobo HDD Bad Sector Repair in my opinion is a sales gimmick to try to get money from users who do not know how a hard disk works. Software cannot repair physically damaged sectors of a disk. It takes a trained hard disk technician and very sensitive equipment within a laboratory setting to repair such damage.

I also linked directly to the company because the site you linked made my system security unhappy.

If the software configures the disk to fix bad sectors that are not physically damaged, that is different, but still no reason to spend money on it. The diagnostic utilities available through Seagate and Western Digital (as well as others) already have this for free to users with their drives. HD Diagnostic

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

oh ok thought you was talking about that thread
as pcbugfixer didn't use that at all in his tut i don't think i would use it
but doing what he suggested might not be a bad ideal it might take along time & cut my 320gb hdd in half or even less but it would be worth it to me especially if its only in half or at least 100gbs
the time & energy vs $$$ time & energy wins lol so do you think his tut would work to do what im trying to do

if you remember the check disk at one time didn't report no error for a week if not more & that was due to me not putting stuff on my hdd once i put a 30gb folder from my xbox on my pc among other files the pc started acting up giving me 1st the water mark windows not valid after fixing that i ran check disk & tons of errors that's when i asked to delete everything in the drive so i did & no errors so i reinstalled win7 to the drive no sounds no issues but i think if i start loading up the drive it will give errors but if i don't im thinking its not going to change to much
