View Full Version : How I love thee chkdsk
I can't begin to tell you how many boot up problems I've solved with chkdsk /r from the recovery console.
For example, I'm on my second repair today and it's a Gateway laptop. Boot produced a BSOD that flashed for a fraction of a second, then shut down. So I used the start up menu to disable auto shutdown/restart on errors. The BSOD referred to registry corruption. So I ran chkdsk /r and the system booted fine. The log shows numerous indexes fixed, as well as bad clusters. I'm running the second chkdsk now, and depending on what that log shows, will determine my next move. Although I suspect the drive is fine and the reg prob was actually caused by software corruption/conflict.

What's funny (not funny haha, but funny weird) is that chkdsk is an old MS-Dos command (chkdsk and chkdsk/f).
Then Windows had Scandisk.
Then XP had chkdsk again.
I'm thinking Twilight Zone episode.:noidea:
Don't forget "Error Checking":D
Well, chkdsk ran clean the second time...will run a third to confirm.
In the meantime I ran SAS. No wonder the system had reg corruption: Almost 400 infected files/reg keys caused by about 20 various forms of Trojans and Adware.
I'll run BD, then sfc /scannow and close the case.

Anything that bad... wipe and load!
Anything that bad... wipe and load!
Nah...
After SAS, chkdsk /r, and an sfc /scannow, I tested the system. No file corruption was evident, and all programs worked fine. After the chkdsk, XP reported that it replaced some corrupt reg entries.
It would take some lethal system file corruption before I decided to wipe and load. In addition, an XP repair is often a better choice than a clean install for the average user.

Nick,
Checkdisk was still present in 98 and Me, it just had little function.

True as those versions were still based on dos.
But the common opinion was to run scandisk instead of chkdsk.
Wasn't it?:confused:
I hated to lose dos-based OS.:cool:

I love chkdsk too! However, in one recent case it only delayed the inevitable. The 3-year-old Dell notebook had BSODs preventing the PC from booting. I ran the built-in diagnostics and saw that the hard drive was failing. One chkdsk later it booted long enough to get everything important off. I rebooted and got another BSOD, so after a 2nd chkdsk it seemed to work, but I suggested a cheap 40 GB notebook HDD from Newegg.
Further information:
If you access chkdsk through the tools on your hard drive, you get two options:
1) Automatically fix file system errors.
2) Scan for and attempt recovery of bad sectors.
The switch in the Recovery Console for option 1 is "P". The switch for option 2 is "R"
NOTE: R implies P
I have read posts about techs using multiple chkdsk switches from the Recovery Console. That doesn't work. By default, chkdsk looks at the first switch and ignores any other switches. For example, if you run chkdsk /p/r from the RC, chkdsk will not recover bad sectors, as the "R" is ignored.

Probably SuperAntiSpyware (http://www.superantispyware.com/). It has a free version that does not include real-time scanning.
btw - I have a tutorial on CHKDSK (http://pirules.com/xp_chkdsk.aspx) on my site now. Looking at the screenshots, it's back when I had a trial (useless-couldn't do anything) of Partition Magic & used Avast!...
Edit - sorry, didn't see the 2nd page. :nono:
