"Stage 4: Looking for bad clusters in user file data ...

Windows replaced bad clusters in file 30A9

of name \Program Files x86\Steam\steamapps\depotcache\414341_depotcache_4.csd.

An unspecified error occurred by chkdsk

I didn't have access to my external Seagate 700 GB, so I got EaseUS Data Recovery and recovered the 250 GB I had used. I use Win 10.

Reformatted the drive and started copying files to it. It started the process, but it would freeze. At times, the drive would just simply disengage and the process was stopped because it could not find the drive. I did this several times, advancing slowly,
but then I decided to check it.

I used "chkdsk f:/r" from Command prompt and it completed the five stages, but at the end, it reported:

"an unspecified error occurred (6e74667363686b2e 137a)" and

"an unspecified error occurred (6e74667363686b2e 1713)"

I have not been able to find any suggestion on what to do. Could you help, please?

 

Chkdsk in command prompt

Why does running chkdsk in command prompt as administrator in windows 10 take so long? It looks like it will take weeks. Incidentally, after around 6,000 clusters checked out of 835,248 clusters that hard drives Properties - Tools became accessible enabling
chkdisk without command prompt. In a few days I will stop command prompt and run chkdsk from Tools.

 

command prompt will not open in safe mode with command prompt

Would I just follow the same steps within safe mode after hooking up to the other system?
