From: jw on 7 May 2010 04:37 I have a 1TB external hard drive (USB) and it has been working sans problems. Now suddenly this morning, when I booted up cold, Chkdsk wants to do its thing on it. That's okay, but Chkdsk hung at stage 4 (checking file data) at 0%. I re-booted, and XP came up properly. Windows Explorer shows the folders and files to appear intact. What would you do? Duke

I had a file system on a partition fail CHKDSK, and I immediately copied all the data off, tested and cleaned up the disk, then copied the data back. You should not allow latent (sleeping) faults to accumulate. Say you have "one tiny problem" today with the file system. Tomorrow, another tiny thing happens, but combined with the first problem, a whole directory goes missing. You'd be pissed. If you see known faults developing in a system, don't let them fester. Fix it, as time allows. Now, moving 1TB of data, over a 30MB/sec USB2 interface, is going to be slow, so it could take a while to clean up. To copy the whole partition, you could use Robocopy, as it keeps a log of what was done, what failed and so on. I use that for doing whole partitions. Robocopy will do a number of retries, as specified by the command line parameters. This is a form of synchronizing utility, but I usually copy to an empty partition, so there are no files already on the target disk. robocopy Y:\ F:\ /mir /copy:datso /dcopy:t /r:3 /w:2 /zb /np /tee /v /log:y_to_f.log (Command line version XP026 of robocopy, should be included in this...) http://technet.microsoft.com/en-us/magazine/2006.11.utilityspotlight.aspx Also, always read the reviews on Newegg, for any of these pre-built drive and enclosure solutions, to see what their failure rate and characteristics are like. Certain products in the past, "dropped like flies", in some cases losing all user files in a matter of two days after purchase. In other words, a user transfers all their backups to the new drive, erases the old, only to find two days later, the new drive is dead and all the files are gone. Always review what is known about a unit, to decide what your handling policy should be. Say, for example, you buy two 1TB units, and they're the "drop like flies" kind. You would duplicate files on the two units. That way, you have some opportunity to save the files, if one unit fails. If you operate the new purchase, as a 2TB storage facility, and one drive drops dead in two days, you've lost 1TB worth of files. If a product doesn't give the appearance of reliability, you can use redundancy to help ease the situation if there is a failure. Paul

Have you run CHKDSK a 2nd or more times ??? what happened ? You can get, for free, simple Disc Check & info utility programs from most of the Disc Manufacturers web sites...e.g. Seagate Tools ... You need to look at that discs SMART info report. (\__/) (='.'=) (")_(") mouse (whirrrr ! click!...click!...whirr!)

I did a cold boot this AM, and the CHKDSK did not occur. I will look for a disk checker though. The drive is a FANTOM 1TB GF1000EU. I have had it over a year, Thanks Duke > >You can get, for free, simple Disc Check & info utility programs from >most of the Disc Manufacturers web sites...e.g. Seagate Tools ... >You need to look at that discs SMART info report. >(\__/) >(='.'=) >(")_(") mouse (whirrrr ! click!...click!...whirr!) > |
