Soo-kabashada Software-^{(Software Recovery)} ku waxay soo martay waddo dheer iyo soo kabashada software ka soo kabsan kara faylasha kaydinta qalabka ama Hard Disk-yada xitaa marka si buuxda loo qaabeeyey. Waxaan shakhsi ahaan dib u eegnay dhowr software soo kabashada xogta^{(data recovery software)} , iyo haa, waxay qabtaan shaqada, xitaa haddii qayb ahaan. Maqaalkan, waxaan ku arki doonaa sida uu u shaqeeyo, iyo sida aad u tirtiri karto Hard Disk-gaaga, oo ay ku jiraan MFT , nadiif ah si looga hortago soo kabashada faylasha la tirtiray.

Waa maxay Jadwalka Faylka Master-ka (MFT)

Jadwalka Faylka Master^{(Master File Table)} - ka wuxuu gaar u yahay NTFS , kaas oo la mid ah buug-yaraha. Waxay haysaa diiwaanka dhammaan faylasha laga heli karo qalabkaas kaydinta. Marka laga reebo tan, macluumaadka kale sida cabbirkiisa, wakhtiga iyo shambabada taariikhda, oggolaanshaha, iyo macluumaadka ku jira, ayaa lagu kaydiyaa MFT midkood . Marka faylal badan lagu daro, mugga ayaa sii kordhaya. Waa sababta aasaasiga ah ee OS u kaydsanayso qayb ka mid ah kaydinta, taas oo ka yar wadarta guud ee bannaan ee la heli karo.

Marka faylka la tirtiro, gelitaanku weli wuu jiraa, sidoo kale faylka. Si kastaba ha ahaatee, gudaha MFT , gelitaanka faylka waxaa lagu calaamadeeyay inuu yahay bilaash. Markaa marka fayl cusub yimaado, meesha dib ayaa loo isticmaali karaa. Ilaa^(Till) markaas, xogtu waa sida ay tahay, taasina waa sida Software -ka Soo-kabashada u shaqeeyo. ^(Recovery)Waxay eegi doonaan miiska MFT oo ku tusi doona faylasha tirtiray, sidoo kale waxay kuu ogolaanayaan inaad dib u soo celiso.

Sida loo nadiifiyo Hard Disk-ga iyo MFT

Markaa hadda oo aad ogtahay sida ay u shaqeyso, waxaa jira laba siyaabood oo looga hortagi karo soo celinta. Waxaad si buuxda u tirtiri kartaa diskkaaga adigoo isticmaalaya qaar ka mid ah software tirtirka oo sugan^{(secure delete software)} - si ugu dambeyntii, miiska MFT wax uu muujiyo. Habka labaad waa haddii aad wax kale ku qori karto xogta faylasha tirtiray. Markaa xitaa haddii MFT ay leedahay goobta faylka, xogtu waxay noqon doontaa mid aan sax ahayn.

Aynu eegno laba software oo bilaash ah oo taas kaa caawin kara. Inta aad awooddo, in aad sameyso hawlgalladan marar badan, SSD waxay u badan tahay inay yarayn doonto nolosha SSD .

1 ] Cyrobo waxay ka hortagtaa soo kabashada

Interface-ka ayaa si toos ah u socda. Fur software-ka, oo waxay ogaan doontaa qaybaha ku xiran kombiyuutarka.

• Dooro qaybta aad rabto inaad ku socodsiiso hawlgallada ka-hortagga soo kabashada.
• Shaashadda soo socota, waxaad dooran kartaa ikhtiyaarka ah inaad ku qorto xogta adigoo isticmaalaya meelo bannaan, dabeecad random, lambarka random, calaamado farsamo oo gaar ah.
• Markaa waxaad u baahan tahay inaad doorato nooca amniga, laakiin maadaama kani yahay nooca bilaashka ah, ma awoodid. Hadaba ku dhufo Next .
• Ugu dambeyntii, waxaad dooran kartaa inaad nadiifiso miisaska MFT boqolkiiba diskka bilaashka ah si dib loogu qoro. 100% ayaa lagula talinayaa.
• Ku dhaji tan, software-ku wuxuu raadin doonaa faylalka la tirtiray, dib buu u qori doonaa, oo sidoo kale nadiifin doonaa gelinta MFT .

Inta ay qaadanayso in lagu dhammeeyo tan waxa ay ku xidhnaan doontaa xawaaraha darawalka adag. Waxay ku qaadatay ku dhawaad ​​50 daqiiqo HDD -gayga hal qoraal.

Soo deji nooca bilaashka ah^{(Download the free version)} ee Ka-hortagga Soo kabashada^{(Prevent Recovery)} . Waxay bixisaa in la tirtiro iyadoo la isticmaalayo xogta MFT oo aan lahayn wax xaddidaad ah. Nooca Pro wuxuu bixiyaa algorithm ammaan oo wanaagsan si loo tirtiro feylasha, interface ka wanaagsan, iyo taageerada mudnaanta leh. Software-ku wuxuu sheeganayaa inay isticmaalaan 12 algorithms amniga si loo hubiyo in xitaa adeegyada ammaanku ay ku adag tahay inay ka soo kabtaan xogta darawalka jira.

2] CCleaner Masixi Meesha Xorta ah ee MFT

CCleaner waxay bixisaa qaab isku mid ah laakiin leh hab ka duwan. Habka koowaad waxa weheliya hawl-galkeeda nadiifinta, tan labaadna waa qalab meel- marineed oo bilaash ah^{(Wipe Free Space)} oo u heellan .

Tirtir dariiqyada Booska Xorta ah

Markaad tan dejiso, CCleaner wuxuu sii wadaa tirtiridda faylasha si joogto ah isagoo isticmaalaya farsamada bannaan ee MFT mar kasta oo aad tirtirto faylka.^(MFT)

• Fur CCleaner , oo tag Options > Settings > Wipe Free Space Drives
• Dooro darawalka aad rabto inaad ku sameyso mar kasta oo aad tirtirto faylasha
• Calaamadee sanduuqa oranaya Tirtir Meesha Xorta ah ee MFT^{(Wipe MFT Free Space)}

Wadida Wiper

Tani waxay faa'iido leedahay markaad u dhiibto PC-gaaga qof kale ama haddii aanad hore u haysan ikhtiyaarka kore.

• Tag Tools> Drive Wiper
• Ka dooro meel banaan oo kaliya hoosta masax
• Dooro nooca tirtirka amniga, kaas oo noqon kara hal mar ilaa shan iyo soddon jeer.
• Dooro hal ama in ka badan
• Ka dib dhagsii masax^(Wipe) si aad u bilowdo hawsha.

Qeybta ugu fiican ee isticmaalka qalabka ayaa ah inaad ku isticmaali karto disk adag oo jira adoon ka welwelin inaad lumiso xogtaada. Maadaama ay kaliya dib u qorto wax kasta oo bilaash ah - inta kale ee xogta waa badbaado.

Ma^(Does) tirtirtaa Shaxda Faylka Master-^{(Master File Table)} ka?

Waa su'aal adag sababtoo ah waxa dhabta ah ee muhiimka ah waa kan algorithm ammaanka loo isticmaalo in lagu tirtiro xogta. Waxaa jira software-dhamaadka sare ah oo soo saari kara xogta xitaa haddii aad tirtirtay hal mar ama jebin kara algorithm-ka loo isticmaalay in lagu tirtiro xogta. Waxaan ku tijaabinay software-ka soo kabashada ee aan inta badan isticmaalo si aan u tijaabiyo soo kabashada, waxaanan arkay inay shaqaynayso. Si kastaba ha ahaatee markan, waxa ay ku guuldareysatay in ay soo kabsado xogta markii la sawiray.

Cyrobo waxay ka hortagtaa natiijada soo kabashada

Waxaan ku aragnay boqolaal faylal ah oo ku jira galka temp iyo dib u warshadaynta^(Recycle) , laakiin midkoodna lama arki karo soo kabashada ka dib. Sawirka hore u maray ma awoodo inuu soo celiyo wax fayl ah, laakiin wuxuu muujiyay magacyada faylalka halkan iyo halkaas.

CCleaner tirtir natiijada booska bilaashka ah ee MFT^{(CCleaner Wipe MFT Free Space result)}

Natiijooyinka ka soo baxay CCleaner halkaas oo aan ku isticmaalnay Wipe Driv e^(Space) Feature (^(Feature) Meesha Xorta ah oo keliya) ayaa ahaa mid xiiso leh. Waxa kaliya ee aan arki karay waxay ahaayeen tiro badan oo faylal ah oo lagu magacaabay ZZZZ labadaba sawir degdeg ah iyo mid horumarsan. Waxay u egtahay in CCleaner uu qabtay shaqo aad uga wanaagsan marka loo eego Cyrobo Prevent Recovery .

Waxaan u maleynayaa inay u fiican tahay macaamiishu inay helaan ikhtiyaarradan oo kale. Qaar ka mid ah OEM^(OEMs) -yada xirmooyinka softiweerka ah si ay u tirtiraan nadiifinta darawaladooda, laakiin haddii ay kugu adag tahay inaad aaminto, isticmaal mid ka mid ah kuwan. Sidoo kale, haddii ay muhiim tahay, waxaan soo jeedin lahaa in la raadiyo software xirfad leh.

How to wipe Hard Disk and MFT clean to prevent recovery of deleted files

Sоftware Recovery has come a long way and recovery software thаt can reсover files from storage deνices or hard disks even when it is completely formatted. We have personally reviewed several data recovery software, and yes, they do work, even if partially. In this post, we will see how it works, and how you can wipe your hard disk, including the MFT, clean to prevent recovery of deleted files.

What is the Master File Table (MFT)

The Master File Table is specific to NTFS, which is like a logbook. It maintains a record of all the files that are available on that storage device. Apart from this, other information like its size, time and date stamps, permissions, and data content, is stored either in MFT. As more and more files are added, the volume keeps increasing. It is the primary reason why OS reserves part of the storage, which is less than the total available space.

When a file is deleted, the entry still exists, and so does the file. However, in MFT, the entry for the file is marked as free. So when a new file arrives, the place can be reused. Till then, the data is there as is, and that’s how Recovery software works. They will look at the MFT table and show you the deleted files, and also let you recover it.

How to wipe Hard Disk and MFT clean

So now that you know how it works, there are two ways to prevent restoration. You can completely wipe your hard disk clean using some secure delete software – so that eventually, the MFT table has nothing to reveal. The second way is if you can overwrite the deleted files data with something else. So even if the MFT has the file location, the data will be invalid.

Let us take a look at two free software that can help you with this. While you can, perform these operations often, on an SSD it will likely reduce the life of SSD.

1 ] Cyrobo Prevent Recovery

The interface is straight forward. Launch the software, and it will detect the partitions connected to the computer.

• Select the partition for which you want to run the anti-recovery operations.
• In the next screen, you can choose an option to overwrite data using spaces, random character, random number, special technical signs.
• Then you need to choose the type of security, but since this is a free version, you cannot. So click Next.
• Lastly, you can choose to clean MFT tables percentage of free disk to be overwritten. 100% is recommended.
• Post this, the software will search for deleted files, overwrite them, and also clear the MFT entries.

The amount of time taken to complete this will depend on the hard drive speed. It took around 50 minutes on my HDD for a single overwrite.

Download the free version of Prevent Recovery. It offers to wipe using MFT data and has no restriction. The Pro version offers a better security algorithm to delete files, better interface, and priority support. The software claims that they use 12 security algorithms to make sure even security services find it hard to recover data from an existing drive.

2] CCleaner Wipe MFT Free Space

CCleaner offers the same feature but with a different approach. The first approach is along with its cleaning operation, and the second is a dedicated Wipe Free Space tool.

Wipe Free Space drives

When you set this up, CCleaner keeps deleting files permanently using MFT free space technique every time you delete a file.

• Open CCleaner, and go to Options > Settings > Wipe Free Space Drives
• Select the drive for which you want to perform every time you delete files
• Check the box which says Wipe MFT Free Space

Drive Wiper

This is useful when you are handing your PC to someone else or if you do not have the above option enabled earlier.

• Go to Tools > Drive Wiper
• Select Free Space only under Wipe
• Choose the type of security wipe, which can be one time to thirty-five times.
• Select one or more drive
• Then click on the Wipe to kickstart the process.

The best part of using the tools is that you can use it on an existing hard disk without worrying about losing your data. Since it only overwrites whatever is free – the rest of the data is safe.

Does deleting Master File Table work?

It is a tough question because what really matters is which security algorithm was used to wipe data. There are high-end software that can retrieve data even if you have wiped them once or can break the algorithm that was used to wipe the data. We tested it with a recovery software I use often to test recovery, and I had seen it work. However this time, it failed to recover data when scanned.

Cyrobo Prevent Recovery result

We saw hundreds of files in the temp folder and Recycle bin, but none of them could be viewed after the recovery. The advanced scan was not able to recover any file, but it did reveal file names here and there.

CCleaner Wipe MFT Free Space result

The results from CCleaner where we used the Wipe Driv e Feature (Free Space only) were interesting. All we could see were tons of files named with ZZZZ in both quick and advanced scan. Looks like CCleaner did a lot better job compared to Cyrobo Prevent Recovery.

I think its good for consumers to have options like these. Some of the OEMs bundle software to wipe clean their drives, but if you find it hard to trust, use one of these. Also, if it’s important, I would suggest looking for professional software.
