chkdsk - An unspecified error occurred

Since I could not boot anymore I mounted an SSD into an external case and run chkdsk /f, and it comes up with:

Stage 1: Examining basic file system structure ...

333056 file records processed.

File verification completed.

21395 large file records processed.

0 bad file records processed.

Stage 2: Examining file name linkage ...

An unspecified error occurred (696e647863686b2e 532).

An unspecified error occurred (6e74667363686b2e 1713).

I'd like to know if this is a hardware problem, or what to do, since the drive is still under warranty grace period.

I can browse the file system normally, and I came to this point after running chkdsk and, following directions in the events log, chkdsk /spotfix (however it went on asking for chkdsk /f).

In case it could be relevant, I am attaching
full log of these two attemps (before the one pasted on this post).

 

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 /f /r E: freezes at stage

of chkdsk said I had errors on my external hard drive and shoul run disc repair.

from command prompt i ran chkdsk /f /r E: as suggested

but now the process stalls at stage 4: looking for bad clusters in user file data ... Progress: 19 of 114672 done; stage: 0%; Total: 0% ETA:30:05:46 ...

what do I do now?
