Ultimate Boot CD is a live CD on which you can start your computer and that provides programs including HDAT2.HDAT2 is a program that will test your hard drive and repair the bad sectors if you wish. Indeed, bad sectors are one of the causes of the slowdown of a computer and HDAT2 can exclude them the hard drive. Thus, Windows will stop block by attempting to access to those defective sectors.
HDAT2 - HDD Bad Sector repair
MS-DOS start the HDAT2 boot disk and said hdat2 is compatible with DOS.As you are under DOS (MS-DOS 6.22 displayed on the previous image), you type "hdat2" (on a QWERTY keyboard) or "hdqt2" (on a QWERTY keyboard). This will print "hdat2".Then, press Enter.
If a bad sector of the hard drive prevents HDAT2 to test your hard disk completely, you can test it by starting by the other side. So, HDAT2 will test your hard disk from end to start, instead of starting from the beginning of the hard disk.
HDAT2 works with drives connected via SATA, ATA, ATAPI interfaces and supports any file system. The main function of the program is to search for and recover BAD sectors on the disk. It can also be used to check the MBR boot area for FAT12, 16 and 32 file systems. Testing large-volume disks can take quite a while. Based on the observations of 500 GB HDD users, the program checks approximately forty minutes. It will take even more to restore the BAD sectors.
I wanted to perform badsector fix after smartctl check but fdisk -l never found and HDD. Next I've used GParted Live but it also didn't found any HDD. I was so confused so I thought that whiping the HDD using dban will be a good idea (if it find any hard drive, it will be a success). So was doing that freaking cleaning, but new exception occured. I've some logs here.
I thought hmm, I've no idea what gone wrong. Another I/O exception? Maybe caused by CPU overheating (I've got so many events with that warning, or because HDD is just broken) or it was just a bad sector issue.
After night, I've come to the see results but it checked only 2.89MB in 8:16h and any of these checked sectors are marked as bad sector with Uncorrectable Data Error or Address Mark not found. warning. After some calculations I realized that this operartion will take 100 years to complete because the hard drive has 320GB capacity. And I don't have so many time.
HDAT2 is software that runs on the DOS and available on the rescue tool fix the hard drive is bad sector. HDAT2 looks like MHDD and Victoria, but this development has another advantage, for example, it can operate with almost all the disk interface ATA / ATAPI / SATA, SSD, SCSI and USB. Please note that to operate, you will need to create a boot disk or floppy disk and then we start from there and start working.
Manually add bad sector to $BadClus Page 1 of 1 [ 12 posts ] Previous topic Next topic AuthorMessagemakinen Post subject: Manually add bad sector to $BadClusPosted: December 26th, 2006, 5:26 Joined: December 24th, 2006, 9:39Posts: 7My hard disk has many weak sectors, can I modify the $BadClus manually to prevent the system to access these sectors. Cos Chkdsk cannot identify these weak sector.

Does makebad revertable or permanently bad? Cos the firmware of my hard disk is corrupted. I guess this is the reason for so many weak sectors which occur intervally at first 60% of the disk. I am seeking the way to solve the firmware problem. If makebad is not revertable then I may not try.Top Spildit Post subject: Posted: December 26th, 2006, 14:12 Joined: December 19th, 2006, 8:49Posts: 10961Location: PortugalMakeBad can be reverted by deleting the partition and making a new one. This will destroy all your data but will revert the effects of MakeBad. Think of MakeBad as a scandisk but wile scandisk can only mark the bad sectors as bad so that those sectors can no longer be used (until you full-format) Makebad do the same but to "weak" sectors (the ones that take more time than normal to read/write to).If your firmware is damaged you will need the expensive PC3000 or an equivalent expensive tool to fix it, but the best option is to get a new HD.Good luck._________________1Q9xrDTzTddUXeJAFRn37aqh1Yr6buDCdw - (Bitcoin Donations)paypal.me/Spildit - (PayPal Donations)The HDD Oracle - Platform for OPEN research on Data Recovery.Top rameez Post subject: Posted: December 28th, 2006, 3:27 Joined: June 27th, 2006, 11:33Posts: 2332Location: In ur HDD !How did u check that there is a problem with your firmware ?Top makinen Post subject: Posted: December 28th, 2006, 7:38 Joined: December 24th, 2006, 9:39Posts: 7When I use HDAT2 to fix the disk weak sector, it said the firmware is corrupted.

I am currently on my first run with it now. These huge drives nowadays take long time lol. So I just want to get this right when you say deleting the partition will undo what makebad does? The readme says to run MakeBad first and then create partition and then format. Readme wrote:Makebad works in this fashion: transform al these weak sectors in really "bad" UNC sector, so after this operation you may re-format(a FULL reformat and an NTFS partition is required!) your hd under Window, so now OS will mark all these UNC sectors as bad cluster and no longer will utilize it.From this moment performing a>chkdsk x:will tell you that bad sector does exists.This confuses me a bit as it looks what you are saying is that this works more like a chkdsk that requires a partition instead of raw drive that marks the sector bad on the G-list or p-list (still working on getting those right lol). Could you set me straight on this? It be good to hear from someone with some hands on knowledge. Perhaps you could help my curiosity some that if it is run on a sector that contains data, does it just make the sector bad rendering the data in that sector destroyed/unaccessable? I am familiar with how chkdsk works by moving the data from the sector and then marking it bad. I was under the impression that MakeBad simply marks the sector bad and does no moving of any data. So running it on a partition that is formatted with says Windows would basically just destroy it by marking sectors bad that contain data. Secondly, other then the "automated process", how does this different then using the makebad command from within the normal mhdd? While I am at it hehe,If using the makebad command to manually make a sector bad, would it be suggested to "Writing sectors to a file" and then make bad and then "Writing sectors from file to the drive" to a different sector? Is this even capable from the command line? Useful for a working Windows with just a couple weak sectors...Any help or advice on this is greatly appreciated Top Boujii Post subject: Re: Manually add bad sector to $BadClusPosted: December 12th, 2013, 6:02 Joined: December 12th, 2013, 3:56Posts: 15Location: Cape May, New Jersey, USAJust can't quite figure it out here. I am using the manual makebad and putting in sector 5701545 and it says completed.But when I reboot the computer and do a scan it not showing as being marked bad and just shows warning again for >500ms.I've tried raw drive (unpartitioned), partitioned, partition with NTFS). Smart status never changes:Reallocated Sectors count remains 100 100 426Reallocate event count remains 100 100 136Am I missing something here? Like SMART isn't suppose to show it and a rescan (F4) does not either?Top Boujii Post subject: Re: Manually add bad sector to $BadClusPosted: December 12th, 2013, 16:31 Joined: December 12th, 2013, 3:56Posts: 15Location: Cape May, New Jersey, USASo I've been searching and browsing around the forum and found this...BlackST wrote:It is IMPOSSIBLE to add defects to lists manually without knowing organization of firmware or how to do it / specialistic equipment. It is possible to 'make bad' and it is locked out BY FILE SYSTEM or make a soft error that is added to grown defect list later but it is just cosmetic.So what I thought was supposed to be happening was in fact NOT! OK that's cool. At least I have an understanding that the G and P list can't be written to normally and what the differences are between the two. Now I'm still not quite sure I understand the correct procedure/requirements for using the makebad command from within mhdd..Since it does not write to the P and G list, I can only assume it requires a NTFS partition in advance to be on the drive? Does it need to be formatted?Basically I just don't know the proper requirements/procedure for running the makebad command.Top Display posts from previous: All posts1 day7 days2 weeks1 month3 months6 months1 year Sort by AuthorPost timeSubject AscendingDescending Page 1 of 1 [ 12 posts ] Main Forums home Conventional hard drives 2ff7e9595c
