Bad File - corrupt slow - bad sector?

[cme4pif]

I have a MS-Access datafile on a linkstation pro LS-V1.0TL that is very active -- 4 users change it all day long. A few weeks ago the file became corrupted, and we used the Access database repair tools to fix it, but since then the file has been very slow to access. We copied the file to a local PC drive and it is fine -- it acts very fast -- but when we go back to use the original file on the Buffalo LinkStation it is very slow. This sounds to me like a bad sector on the hard drive, but we ran the Disk Check function and it zips through in a few seconds and says nothing at all. The blue light on the unit is on steady -- no error codes are flashing. Is that a clean bill of health for the drive? it was sure fast to check the whole 1TB drive . . .not confident it check it all. 

Is there a comprehensive disk check and defrag I can run to clean up a drive or check it? Can I mark part of the hard drive as unusable and move the file?

Is there a log file I can review? I have the SMTP email report turned off.

If it is like what you say. You could rename the folder it's in, then make a new folder with the old name, copy all the files to the folder.  Keep the old files aound.  And i there is a bad sector, trying to write or copying files on to them should cause up an error message.

 

If it is a bad sector, the original files will still be using them even after renaming the folder they are cotained in, holding on to those sectors.

Hi

Yes I can do that but the way, in fact I already did. Unfortunately I have things set up that will become part of my backup, and if I keep making these dead files I will keep making bigger back ups, it really is not a long term solution. I am not a UNIX guy, I have never understood how UNIX based systems approach what Windows calls checkdisk and defrag. Are there no maintenance programs for NSA servers?

First, use http://www.goodlucksoft.com/copy-bad-disk.html" target="_blank">CBD(Copy Bad Disk) to copy files sitting on bad sectors to a healthy HDD. Then use http://www.goodlucksoft.com" target="_blank">PBD(Partition Bad Disk) to isolate bad sectors of the HDD.
