Absolutely. Semaphore is what controls access to devices from multiple requests. That message usually means the resource took so long to respond to a request that the computer decided there is a problem and the request is unlikely to be fulfilled. Instead of being frozen forever, it times out. What...

So today i tested with a new hdd new cable and i got this:


Is this a hardware related message?

I just checked with Event viewer and i cant find any trace of chkdsk logs (tried many solutions, powershell, specific app etc). If i run chkdsk on a fixed drive i have a log in Event viewer. It was strange for me so i started fiddling and searching. I noticed something that may be the problem. Becau...

Maybe i confused you with my details. So: - The file is not the same every time. It is one of the files that are synced in the specific run. It may be a zip file , a text file that is empty when opens. It is not steady. - I get the error about corruption from FFS, and that is the time i know that i ...

I have used 5 external HDDs (no USB sticks) in the past 6 months. In the mentioned different machines. In ALL cases : - At some point of time i understood that a file was corrupt.

Hi! I have posted again on the same issue and i see that others also have issus when it comes to FFS and external drives. Certainly there is something going on when FFs syncs with External disks.

I don't think this is a FFS issue, as it would be reported here a lot more if a widespread issue. If it's happening on multiple drives an...

I bought a new disk with new cables and the problem appeared again. I am pasting the output of the CHKDSK. It refers to unidexed files....After CHKDSK i could see the files in the disk. Chkdsk was executed in read/write mode. Checking file system on E: Volume dismounted. All opened handles to this v...

Yeap this is what i mean.....I changed 3 USB disks/cables (different vendors) up to now and it persists.. It does this on both my home machine and laptop so i cant believe that it has to do with the machines. Also i disabled search indexing on the drive and enabled fail safe copy.. Some times i get ...

Hi! For a long time now i keep having a file corruption problem. At random times when i try to sync files between a USB drive and my disk one of the following happens: - Either there is no warning but the sync results are not correct. Meaning that i am expecting to see some files to be included to b...
