Delayed write failed - After a defrag of external USB Drive

Okay update.


I plugged the drive into my other PC - Windows vista - and now all the files are there. So why after a defrag on the XP machine is that computer not seeing this hard drive? How can I get this to work on that PC again? I have all my games that run on that PC installed to this drive.


Thanks.

wow

The hard disk fragments known as file fragmentation, which is due to the file saved to disk scattered in different places, rather than continuously saved to disk within the contiguous clusters. Simply speaking, all procedures of the disk reading and writing operations are likely to generate debris in the disk. In the period of daily use, the user constantly create, delete, update files on the disk, after a long time, the disk will accumulate a large number of file fragments, which would seriously affect the performance of the system, resulting in a waste of disk space, or even to reduce the disk life.

It’s better to clean up the hard drive before to defragment hard disk, and then close all applications. This is because when defragmentation, the system will move many of the documents, if the file is being used by the application, it can not be defragmented, or defragmentation is complete, the program error occurred.

As for the hard disk defragmentation methods, we preferred Windows operating system built-in defragmenter, then you can try other debris finishing programs, and some third-party programs are much faster than the Windows built-in defragmenter, and the results were pretty good.

Defragmenting the hard disk in Windows 2000/XP systems, the user can right-click the hard disk, select “Properties” in the dialog box that appears, click “Tools” tab, click “began to organize” button in the “Defragment” election items group. The system will automatically start defragging.

Okay, the problem isn't knowing how to defrag. Here is what is going on.


I have this external USB hard drive that I have used flawlessly for 1 year on a windows XP computer system. After a while files will normally become fragmented on a hard drive so it is a good idea to defrag the drive occasionally. I went to defrag this hard drive "which worked perfectly up until this defrag" and that is when the "Delayed write failed " error came up. SInce then it won't work at all with the Windows XP Machine.


To test something out I took the drive and plugged it into my Windows VIsta Desktop and it found the drive. Sometimes I can access the files other times i have to turn the drive off and back on to be able to access files. Other files can't be copeid off it like a video I have on there but strangly enough it will play in windows media player off the hard drive itself?


To test it even further i took the drive and hooked it up to my windows XP laptop. THis is the third PC i have in the tests. It showed it in my computer but no folders or files listed at all.


SO far the only system it is working on somewhat is VISTA.


REMEMBER IT WAS WORKING FINE ON THE ORIGINAL WINDOWS XP DESKTOP UNTIL I DEFRAGGED IT. Dueing the defrag it got the Delayed write failed erro and since then it won't work at all with XP. I have tested it on two separte windows xp computers and nothing. Vista is the only one it somewhat works on. SO what is the issue?

What coudl be the problem?

THanks.
