Chkdsk/Partition Anomaly..

Early this morning, as part of my not-so-regular interior cleaning, I decided to open up my PC to blow away some dust and to check if all the fans (PSU, CPU, GPU, Aux) are spinning as they should be. No cables were moved or removed and replaced. The one thing I did new this time was to hook a spare power cable and turn the unit on (minus the kb, mouse, speaker, lan, and monitor cables) while the PC was still at the floor. I did this to speed up the process - so I wouldn't have to do the checking (fans spinning, lights on, etc) back upstairs at the computer table. Naturally, without a keyboard and a monitor hooked up, I just had to turn the unit off after a few seconds.

Now my problem begins after I've hooked up everything and the unit starts running. It boots up fine and detects my 500gb HDD and DVD drive, but as it is going into XP, it loads chkdsk on my E:\ partition (games and pictures). Thinking it was a fluke, since everything was still there, I restarted the unit again.. and the chkdsk thing came up again. Went to the error logs and saw:

Category: Disk
Type: Error
EventId: 55
The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume E:

The same error was logged whenever I would restart. Did an AV scan, Chkdsk, CCleaner, turned off sys restore (in case a corrupted file occured) ... and the chkdsk would keep scanning E:\ whenever I would restart.

Checked around the net for a fix and found methods to break the loop using fsutil and chkntfs. I already considered doing them, but the problem seems to have been solved after I did a chkdsk and defrag of E:\. Did 4 restarts after that. Error logs were clean and no chkdsks took place. Did a final chkdsk/defrag combination on safe mode for all 3 partitions, along with a complete MBAM, ESET, and Avira scan (one after the other) to make sure.

Anyway, can anyone explain this problem? Is it a power issue or a hard drive problem? I'm pegging the cause to that abrupt shutdown I did. Also, why did it affect my non-Windows partition and why did a simple defrag cure the problem? BTW, I defrag 2x a month and that partition is only 60% full. This is the first time it happened and I'm also not underpowered (Corsair TX750, 1 HDD, 1 DVDRW, 1 GTS250).

Thanks!

Are you kidding me? And dont defrag an HDD or partition that shows a check disk error. Man are you asking for it.

When you turn on a computer it POSTs and during that process checks IO ports (USB, PS2,Video, etc) as well as HDDs. The computer probably halted or was scanning HDDs during the POST because of no video connection (or depending on BIOS settings no KBD). Cutting power created an HDD error (probably delayed write). When this happens, ensure that you run a chkdisk with the fix file error option enabled. Ensure that all HDD/partitions are error free before messing with any defrag otherwise you are begging for trouble.

And I would be surprised if you didnt lose some data (file fragments left after chkdisk fixed damaged files). If your lucky it is some obscure data that you may never access in the future, but dont be surprised if one day you click on that .doc, .jpg or .rtf and you get an "unreadable" notification.

Yeah, I did the chkdsk thing with the 3 phases. The defrag was done after a handful of those (in Windows and during restart). What I didn't do was check for bad sectors.

------------
Did the chkdsk /f /r on all drives. Zero bad sectors. Does that mean I'm in the clear?
