Disk defragmenting Crocodile

See also Defragmentation wars.

Defragmenting of Unix/Linux disks is usually not considered to be necessary, not because Unx file systems are necessarily any better than their Windows counterparts, but because Unix systems are usually multi-user and disk access HAS to be fragmented.

At one time, a company named Crocodile made a disk defragmentation tool for Unix. They, and probably every other company that has tried this market, are no longer selling this product.

Crocodile used to be available from http://www.stallion.com. I have no idea of current status; their Web site seems to be having problems just no.

IMHO, a better way to defrag (if you need to at all, and very few Unix systems need to) is to use a product like Edge: http://www.microlite.com to reinstall.

However, people will insist that they need to defrag. Others will say, sure, but you'll need to do it constantly so why bother; http://groups.google.com/groups?selm=10109071555.aa21238@wecan.com.

http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&selm=GJAyp2.vqo%40wjv.com discusses SCSI elevator seeks in conjunction with this. The argument is that SCSI drives optimize disk block access by resorting recent disk block requests for efficient access.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
