Question Failed to read from sector when cloning. Should I continue ?

[dan99t]

Hi,
I am still using Win-7.

I have a HDD where I have saved Win-7 with all settings & Updates till 2020.

I use this HDD in case if I need to install win-7 in another drive by just cloning new HDD from this HDD.

I was cloning a new SSD from this HDD to install win-7 from this old HDD but I got a message halfway when cloning as follows :

" Failed to read from sector " 100 003 656 " from HDD-1. Try to repeat but if error persist use chkdsk.
Direct R/W operation has failed. ( Ox 590001 ).
Input/Output error ( OXFFF1 ) "

It gave me a choice to try again or ignore or ignore all.

I selected " Ignore all " and it installed Win-7 on new SSD.

Windows-7 is working fine on New SSD.

Should I continue to use it & install all my apps & data on this newly cloned SSD or run chkdsk on original HDD ? & then install Win-7 again ?

Couple of my important apps seems to be working fine on this new SSD.

Please advice.

Thank You.

Recommend running "scannow" (SFC /scannow) on the new install to ensure that all Win7 critical system files are intact. Then proceed to use the new install & repair/resolve any irregularities that may pop-up with applications.

Once everything is tested & working satisfactorily, then I would use TESTDISK or SEATOOLS to check the integrity of the HDD and do a (sector/re-map) repair if necessary. (Note: if there is a problem area on the HDD then running CHKDSK /f on it probably will obviate the read error, but at the cost of lost data due to sector unreadability; You need to have a valid error free image for backup.)

After all that, image (ie, write ) over the original HDD image using the checked out/correctly functioning install to SSD.

I have these two old utilities & I ran them & posted it here.
Do they tell anything or I should still go for "scannow" ?

Also this HDD seems to be dying, I would like to make a Back Up copy of it on a smaller SSD. If I do that will old HDD transfer the problems to this new back up SSD ?

Depends.

With problematic HDDes you can get a good (single) read depending on conditions (eg, the HDD temperature or even its orientation at the time).

(Im surprised that your imaging software allowed any kind of restoration given that there was a read error. All imaging apps Ive used are really touchy about fidelity of the image - both recorded & restoration - & will refuse to continue upon any error.)

Recommend to cool the HDD down & then try to get a single pass error free backup of the HDD to your new smaller sized SSD.

If during this process, you get any read errors, then your best bet is to use the first backup (& which seems to work correctly) that was made to your original SSD system (in which the read error was encountered).

Make your backup to the new smaller SSD from that restoration.

I guess I jumped early & installed some app & data to new SSD.
So I will have to try to make new smaller SSD again from that Bad HDD first & the try to run chkdsk ?

Please advice.

Doesn't Windows have some sort of auto-repair function? I would assume that if it's running smoothly from the SSD, chances are it will be OK.

Now, the question is - did something like a bad sector data get copied to SSD? I concur with C1, it's strange that the imaging software allowed the restoration despite the read error. But maybe that is an actual indication it wasn't anything serious?

If you're paranoid but don't want to waste time with a reinstall from scratch, you might as well boot into the recovery menu and choose to "refresh Windows". That should take care of any transferred glitches.

I selected " Ignore all " and it installed Win-7 on new SSD.

Windows-7 is working fine on New SSD.

When you selected ignore all, it probably wrote a zero sector on the SSD against the unreadable HDD sector. Supposing it's a 4K sector, it's probably nothing to worry about. Maybe just some obscure file that won't ever get used. If everything is working fine on your SSD, there is no need to do anything else.

But yes, running SFC /scannow recommendation from C1 is excellent advice. If SFC finds no problem, you are fine, at least as far as your OS data is concerned.

Just make sure that all your personal data is also OK (any images or documents not opening etc. would indicate a corrupted file due to missing sector data).
