Freezing during Check Disk

Hello all. I'm in some desperate need of help. I have a Quad core cpu running windows 7 ultimate 64bit. I made the mistake of having windows do a full (both boxes checked) check disk on all my drives last night.

I have two internal 750gb Sata Seagate Hardrives (one partitioned to 140Gb) and one external WD 750 Gb hard drive.

I woke this morning and the check disk still wasn't complete. Now, it seems to have frozen (not moving above 10% and stuck on same file) and I'm not sure what to do.

We have some large files on it since we use the cpu for photoediting and video editing.

I have heard I don't want to stop the check but I'm at a loss of what to do if it did indeed freeze (not sure if it is really frozen or just taking along time to check one file/sector)

Please help as this computer is used for our business and I don't want to mess anything up!

Thanks in advance to anyone who can help!

This is a response to a post from a Dell customer, but it may help you:

Try ctl-alt-del to break out of chkdsk. Then you need to
delete the next schedule chkdsk(because it senses it
didn't finish) To do that:

Power Off. Then power on, Depress and hold F8

Select "disable error restart"

Click to expand...

Thanks for the response. Will we risk dataloss but stopping it early? If the Cntrl alt delete doesn't work, what should we do?

Also, any idea why this would freeze or how we go about running a full check disk in the future? Is this an indication of problems with the disk? Anyway to tell which disks have already been checked?

Thanks for your help notsogray.

I don't think you'll experience any data loss but then again anything is possible. You should always have a backup just incase you FUBAR your computer anyway, I know I've done so atleast a handful of times.

In regards to whether or not this is a problem... I'd say it depends on which disk it stopped on, if it's an external drive it could simply be a power saving problem. If you want to check on the health of each disk, do so individually and through a bootable disk that way you're not accessing the disk while checking it.

It finished...it just took along time on a few files. Thanks for everyone's help!
