Hej.
Hvordan kan man formaterer sine harddisks bedst muligt, så ALT data bliver slettet, på begge HDD'er. (se min profil for setup)
På forhånd tak.

En low level formatering er vidst det mest grundige du kan få - med mindre du vil tage en hammer eller lign. i brug :e;)
Her er et værktøj til samme...

Kan man ikke bare formatere på den gode gammeldags måde, med at fyre en XP cd i, boote fra den, også give den gazz?

Hvad er en low-level formatering?

Low-Level Formatting
Low-level formatting is the process of outlining the positions of the tracks and sectors on the hard disk, and writing the control structures that define where the tracks and sectors are. This is often called a "true" formatting operation, because it really creates the physical format that defines where the data is stored on the disk. The first time that a low-level format ("LLF") is performed on a hard disk, the disk's platters start out empty. That's the last time the platters will be empty for the life of the drive. If an LLF is done on a disk with data on it already, the data is permanently erased (save heroic data recovery measures which are sometimes possible).
If you've explored other areas of this material describing hard disks, you have learned that modern hard disks are much more precisely designed and built, and much more complicated than older disks. Older disks had the same number of sectors per track, and did not use dedicated controllers. It was necessary for the external controller to do the low-level format, and quite easy to describe the geometry of the drive to the controller so it could do the LLF. Newer disks use many complex internal structures, including zoned bit recording to put more sectors on the outer tracks than the inner ones, and embedded servo data to control the head actuator. They also transparently map out bad sectors. Due to this complexity, all modern hard disks are low-level formatted at the factory for the life of the drive. There's no way for the PC to do an LLF on a modern IDE/ATA or SCSI hard disk, and there's no reason to try to do so.
Older drives needed to be re-low-level-formatted occasionally because of the thermal expansion problems associated with using stepper motor actuators. Over time, the tracks on the platters would move relative to where the heads expected them to be, and errors would result. These could be corrected by doing a low-level format, rewriting the tracks in the new positions that the stepper motor moved the heads to. This is totally unnecessary with modern voice-coil-actuated hard disks.
Warning: You should never attempt to do a low-level format on an IDE/ATA or SCSI hard disk. Do not try to use BIOS-based low-level formatting tools on these newer drives. It's unlikely that you will damage anything if you try to do this (since the drive controller is programmed to ignore any such LLF attempts), but at best you will be wasting your time. A modern disk can usually be restored to "like-new" condition by using a zero-fill utility.

altså en langsom format fra en win cd skulle kunne gøre det. Normalt har jeg ikke tålmodighed til at gøre det så sætter bare en /q på normalt :P .

Læste ikke hele #4 indlæg, nogle vil måske grine, måske lærer jeg noget, hvem ved.
Men hvad er der i vejen med format C:\ ?:(

#5 #6 #7 - med ethvert harddisk recovery program kan man gendanne ALT!!!!!!!!!!!!!!!!!!!!!!!!!!!!! data efter en formatering - det er derfor ikke specielt smart blot at windows formatere en harddisk med følsomt data inden man f.eks. sælger den viddere.
At un-format en harddisk på 250gb tager ca. 15min - og så kan man ellers åbne alt der lå på den før formateringen.
#0 low-level formatering er nok en af de bedste måder, evt. kan du først fylde disken med et eller andet ligegyldigt, f.eks. en iso af linux eller lign indtil(kopi på kopi på kopi osv.) der er 0mb plads fri, det besværliggør også reconstruering af tidligere data - ellers så forvent at det tager en dag at low-level formatere, så lad være med at gøre det hvis du skal bruge pc'en til noget andet samtidigt med :)

jeg ved godt nok heller ikke så meget om det. Men har hørt noget med at den eneste måde at få data til helt at forsvinde på er ved at brænde HD eller sende den igennem en stor kværn eller sådan noget 🙂
Vist nok noget med at der er dansk firma der er verdenskendt for deres evne til at genskabe Data i brændte Computere osv..
tror Det er en større videnskab :)

Der står til sidst, at man ikke skal bruge en low-formatering på IDE/ATA diske. Hvad skal det betyde. Kan man så ikke bruge det?
Jeg har én IDE og én SATA disk.
