The reason for having to do it properly is because the positioning information is either kept with the data it relates to, or on a separate platter. Either way, if it is destroyed, the drive becomes unuseable. Using a separate platter increases access times, chicony cnf 6212 requires thermal recalibration every so often, and the resulting pauses aren t good for multimedia playback. Interleaving At some stage during the low-level format, you may be asked what interleave chicony cnf 6212 want.

Interleaving is a way of improving performance by judicious positioning of data on the chicony cnf 6212, which actually depends on the capability of the whole drive chain i. This will not apply to IDE, ESDI or SCSI drives, since the majority of the controllers associated with them are powerful enough to cope with a sector of data at a time, and will automatically give a interleave see below. After a sector has been read it must be moved from the controller's buffer into the computer. The time needed to transfer that sector's information determines how soon the controller will be ready to read the next one. A interleave exists when sectors are filled one after the other in the proper sequence, i.

If you position sequential sectors alternately, such as 1 3 2 4, you get a interleave, where sector 3 is allowed to pass underneath so sector 2 can be taken up by the controller when it's ready. If you had a less capable controller, you might want to make this looser, such asso you get something like 1 4 6 2 5 7 3. Try to imagine picking balls up from a roulette wheel, if it makes it any easier.

Hard Disk Tables 25 To sum up; an interleave of 1 reads each sector in succession. An interleave chicony cnf 6212 2 reads alternate sectors and requires two revolutions of the disk to read the full track, and an interleave of 3 reads every third block, requiring three revolutions of the disk, and so on. Selection of an interleave where the data rate is excessive for the disk, controller and computer combination will reduce performance, because more disk rotations are required to complete the track read. If you can't change the PC's ability to transfer data internally by increasing the DMA channel speed, for instanceyou must increase the size of the controller's buffer, to at least bytes, which is the size of a standard sector.

The trouble is that you rarely know before you start what is the best interleave, since chicony cnf 6212 whole PC is involved, but there are several programs, notably Spinrite and even some BlOSes that both give you the opportunity to both test and change the interleave factor of your hard disk without affecting your data although you would be well advised to take a backup! Partitioning with FDISK Partitions were originally created to boot from different operating systems; a hard disk can have several, which are managed by the Partition Table at the beginning of it.


The starting and ending locations for each partition are defined, together with which one controls the system during boot-up. Partitions don't know about the chicony cnf 6212 of each other, so your operating systems won't get mixed up only one partition can be active at any time.

The bigger your partitions are, the more you are likely to waste hard disk space, though this will depend on the size of file chicony cnf 6212 regularly handle. With FAT 16, disk space is allocated in clusters, the size of which depends on the size of your partition, which is limited in the first place because FAT entries are only 16 bits long and you can't have more than 65, clusters on any drive, so the bigger the drive is, the bigger the cluster has to be to compensate; 2K clusters mean a maximum drive size of Mb.

The maximum drive size you can chicony cnf 6212 is 2 Gb, from the maximum cluster size of 32K, except with NT which can use 64K clusters. The point is that if a file is smaller than the cluster it occupies, the rest of that cluster is unuseable.

If the file spills over to a second, the remainder of the second is wasted, and so on. Although less FAT space is taken up with larger cluster sizes, to minimise wastage, choose smaller partitions, as far as convenience allows, e. You can have up to 24 logical drives chicony cnf 6212 a physical disk, only because there are only that many letters in the alphabet A and B are already used for floppies.


It is on cylinder 0, head 0, sector 1; the remaining 16 cylinders are not used. This lives on cylinder 0, head 1, sector 1. It will contain information about the DOS version used for format, the chicony cnf 6212 of bytes per sector, number of heads, etc.

DOS keeps a primary and secondary copy. The FAT can be either bit bit entriestaking up 6K per copy, or bit, with 64K bit entries, taking up K for each entry. Bad areas are noted in the FAT and marked chicony cnf 6212 unuseable; these will be either hard or soft errors. Hard errors are physical defects on the hard disk surface, and soft ones occur when data fades to the extent that it cannot be read. It has entries for a bit FAT and for a bit. Some drives, like chicony cnf 6212 Miniscribecan format a higher number of cylinders than officially listed; this particular drive is written down as having cylinders, but can safely be formatted toas it actually has If you use other figures, don't exceed the maximum sectors available use the formula below to calculate this.
