Bad Sectors on source drive not found by chkdsk
Every time I backup a certain drive, I get the message that acronis cannot read a sector. I will hit ignore and get no more error messages. The backup finishes and validates. Then I do a chkdsk on the drive, and chkdsk finds no bad sectors. This has happened 3 times in a row. Any ideas on how to resolve this problem.
You provided no relevant details about the drive, so I can only guess.
Is this an internal drive or an external drive?
Run chkdsk /r on each partition of the drive. If there are hidden partitions, assign letters to them so you can chkdsk. Otherwise you may not be checking the area that contains the problem.
Also run a drive checking utility from the drive manufacturer, as those sometimes catch errors missed by chkdsk.
It is an external drive with only one partition. I will run a drive checking utility from the drive manufacturer. That is a good idea. I did run a scan from a utility called HDTunePro. It said that the drive had 1 bad sector, but it does not have the ability to fix it.
The manufacturers utility should be able to correct that bad sector issue.
Hopefully a utility from the manufacturer will fix the problem. I've been using a simple version of Crystal Disk Info which keeps track of hard drive problems. After a few months with a new Seagate HDD that came in a new Lenovo computer, it starting indicating troubles with the hard drive (I really don't understand most of the information provided by the program) with one or more bad sectors. I think I tried a Seagate utility, Seatools for Windows, but it didn't help (don't remember if I used all possible features), other than saying the drive had some problems. Anyway, the way I came to fix the drive (before I eventually replaced it with an SSD for improved performance) was by writing zeroes to the entire drive, AKA low level formatting. I used a free and very simple program by Roadkil, called Diskwipe 1.2. It is also an option on the TI console, or after booting from the Acronis recovery software CD, using TOOLS. Select Acronis Drive Cleanser, and use the FAST option that writes zeroes in a single pass. Apparently when you write zeroes, the internal firmware (independent of the OS) of the drive marks the defective sector(s) as bad, and no longer uses them. Usually not a problem since most drives have a lot of unused space anyway. But you do have to totally erase the drive in order to write zeroes. Also, if you ever end up doing that, you have to use disk management or some other program, to format the drive again. All of that is essentially a last resort instead of throwing the drive in the garbage, or requesting a replacement under a warranty.
Good luck!!!
Thanks for all your help. This was an extrenal hitachi drive and I did a google search. I found a program called DSKCHKR, similar name to windows CHKDSK, but a different program. It found the bad sector and fixed the problem.
