It's been 20 yrs since I was actually employed as a programmer so please excuse if my "lingo" is out of date, but what I am doing is a valid effort. And again, Avast found these issues when dskchk did not. Interestingly, and it was a surprise to me, since Avast has to read/open files to look for viruses, an "undocumented feature" is that it does find corrupted files when it tries to look for viruses. This obviously takes a long time on the huge drives of today (even a dskchk takes a lot of time and it ignores unused areas).Īnd I am 98% it does not indicate a hardware problem (other than the bad areas I know are present) rather, according to Seagate's website, this general process can often discover bad areas on the drive that other procedures will not (ie, dskchk, which, by the way, apparently marks files "good" when it is run, even if it does not fix or cannot find actual corruption), and then the secure erase "repairs" the area by marking it bad and replacing it with "extra" areas on the drive that are there solely as replacements to bad areas.Īs for Avast, I also understand "decompression bomb" doesn't mean the file is corrupted, only that Avast can't or won't take the time to decompress to examine the file, it's just I didn't remember if that was "the exact" phrase Avast used. what I'm doing a "secure erase" (DOD specs) which writes to each and every space on the HDD, reads it back, then writes it again. It might not be called a low level format anymore, but that's what it is. And fwiw, low level format will not finish for 3 days so I can’t try fixes until then. fwiw: I’ve owned PCs since the 1970s and as long as you’re “not stupid”, viruses are not typically a problem, especially when you have active anti-virus software).Ĥc) Windows Backup/Restore (this is a “must use”).Ĥd) Windows Repair (from installation disk within Windows).Ĥe) Windows Repair from Installation DVDs.Ĥf) Reinstall windows over itself (can anyone confirm that this won’t data existing data or other software).Ĥ?) Check for hardware issues: I’m not sure where this should go in the process because, in “all my years”, “real” hardware issues are rare or they are obvious failing RAMM and HDDs are the exception, because they start slow and BEFORE they become obvious, you’re looking “in a haystack” (4b-4f+). Can anyone confirm this can fix errors not found using the installation DVD repair (I suspect other Windows errors due to failing HDD?ģ) If #2 can’t fix my Windows, can I reinstall Vista on top of itself without damaging existing data or other installed software?Ĥ) Is there any forum here that discusses the best “flow chart” for fixing errors? Or how does this look(?):Ĥa) backup everything (often and especially before starting a repair attempt).Ĥb) Check for viruses (1st=ALWAYS have/use anti-virus software. While Avast didn’t find any destructive viruses, it did find a lot of corrupted data files as well as files that were too large for it to check( forget the phrase it used = ”decompression bomb”?) and I cannot save Avast (DOS) logs on my PC (needs floppy or bootable USB).ĬhkDsk failed to find any errors it was Seagate Tools found intermittent drive issues (1st run failed,2nd run passed, but decided to do low level format in an attempt to fix disk errors).ġ) Is there any specific software on UBCD that would be best for checking “file integrity” for every file - to discover the corrupted files Avast found that obviously were affected by the HDD failings? Remember, chkdsk did NOT find problems.įwiw: Since I have many older backups, I can likely find good copies of corrupted files… once I find out which files were corrupted by my failing disk.Ģ) Vista repair (on the installation CD) found no errors but apparently I can run the Vista installation disk from within windows and presumably this could correct my Backup/Restore issue. I copied all my data files to my newer PC and since the failing HDD also had a virus, I ran Avast (DOS mode) on the data which was copied to a newer PC. I’m currently doing a low level format to try to fix any HDD errors (hopefully, but new drives ordered anyway!) but I could use some help. I have a failing HDD and it corrupted Windows Backup/Restore function.
