Not sure if defraggler has messed up my files and HDD health

[Cozzie]

Lead up to my internal HD issue. (Btw I have a Seagate 2TB Barracuda)

 

-My harddrive was like 20% fragmented.So over like 2 weeks I have been defragging on and off. 

At first I defragged the whole drive in one go at over a few nights. It was taking foreveerrrr. So someone suggested I can do a section of files bit by bit. I selected 1 group, it went down to 17%, then another group down to 15% etc. Until it got down to round 12% so I decided to defrag in one whole go again, it was making slow but better(ish) progress.

 

The issue/s

 

-I woke up Saturday to see my PC screen had frozen. I could move the mouse but that was it. I could not sign into Windows as it was on the page for some reason (looks like PC might have restarted or rebooted??) Thene my PC screen went black and the message 'Reboot and select proper boot device' appeared randomly. This has never happend before! So I pressed 'ctrl, alt, delete' and basically my PC rebooted and loaded as normal. 

 

-I have been using my PC since then, it has all been working fine but I have become really worried and anxious about my PC/internal HD breaking down.

Also, using HD Tune pro, it shows my internal HD is a healthy desk but it shows an 'Interface CRC error count | attention | Data: 1 (I presume 1 file is either lost or deleted?)

 

Since then I have:

- Only now  decided to buy an external HD to backup/create image file.

-Create a rescue CD

-Tested internal HD using HD tunes (as mentioned above)

-Crystaldisk / info

-Although Seatools for Windows quick test shows fail the first time, 4 more of the same test has it as a pass. Seatools for DOS does not detect the internal HD.

-Possibly buying a new internal HD and cloning old to new (last resort). Although, many have also suggested to me that if HD tunes shows my internal HD is healthy, that nothing is wrong with it now, that I have been using it alright...then its all fine then?

 

What was suggested to me

-Now your probably thinking how this has got anything to do with defraggler. Well...someone said to me that 'Defragging can stress weak sectors of a hard drive, and randomly getting a no boot device is a bad sign of a HDD dying'. 

-Another point someone told me was that the Interface CRC was due to SATA cable issue (how to fix this?) and if the number does not change you dont have to worry too much. 

-Also phoned Cyberpower and they said defraggler might have moved a file which caused the "Reboot and select proper boto device"..which could be the case as it only happend the morning of defragging over night.

 

So what I am thinking is that defragging moved a file (the 1 file for the Interface CRC error count), and maybe that file was to do with the HD boot order or something?

 

Not sure what you guys make of it. Sorry if I went on for too long and if half this info is useless

Thanks for taking the time to read my issue :/

Backup your data, then run chkdsk /r on the drive as it be a bad sector(s) which most mechanical hard drives will eventually have. chkdsk /r can take hours to perform on a 2TB hard disk.

I am sure I ran a chkdsk just to check my HD. And then some things happend like:

 'Chkdsk cannot continue in read only mode'' and 'f parameter not selected' and also 'cannnot run because volume not in use'.

 

I also searched my chrome history about this and found out I tried to look up 'Chkdsk found folder missing’ and also ‘where chkdsk moves files’ or something like this. I didnt want to click repair or anything due to data loss maybe.

When I perform the chkdsk/r, will this try and repair the bad sector? Will it fix everything or?

chkdsk doesn't 'repair' files it finds to be corrupted, or if it does, it is basic at best.

if the corruption is something like a broken index, it'll have a stab at correcting but it's usual 'fix' is to simply delete the corruption or to lock the sector.

it's priority is to fix the drive's integrity, it doesn't give a toss as to the file in question.

 

so to answer your last question, if it's a bad sector, that sector is locked and flagged as bad and if possible what was in that sector is moved to a found.000 folder.

the contents of found.000 will be portions of files that were able to be moved out of the bad sector, and renamed to chkdsk.000, chkdsk.001 etc

so unless you had backups, a bad sector equals data loss.

Ok thanks for explaining it, appreciate it! Once I backup and perform chkdsk/r I will let you know results. 

 

I wish it would tell me what the file/data loss is is. Like I mentioned, my PC/HD has been working fine since the Reboot and Interface CRC messages. So I doubt if you would know if this 'data loss' is an important file or not?
