Hello. I have Silicon Image SSDs installed in 10 laptops. Unfortunately, during the tests with the MHDD program, bad sectors were shown. As the equipment was under warranty, I sent it back, but I got a feedback: Of course, the complaint was not accepted. In fact, there is such information...

MHDD in the case of SSDs is only suitable for reading SMART. For me, on a CF memory card connected to ATA, it was able to show transfers of 130MB / s where this card usually works around 30MB / s. MHDD does a surface scan. And since there is no such SSD in the SSD, various problems may arise.

It can be like that. The internal procedures of the SSD firmware theoretically - I have not tested it so I am not sure - may be misinterpreted by MHDD. And indeed - sector - the smallest physical particle of a disk supported is not equivalent to a sector, basically the area seen as a sector by the controller, in an SSD.

Are you sure about this manufacturer name? Enter the SSD model. Perform diagnostics in (with): I usually read SMART in SSDs and know what to do next (I don't play with any scans, benchmarks). Each case (model) requires a specific diagnosis -> see e.g. the topic I am promoting.

So based on the controller Phison PS3111SB . Manufacturer's tool use ( recommended ) or from the appendix below (e.g. evaluate the SMART reading now):

This is a low-level program typically written for HDD. Scanning, as you can see, distorts (and in principle it should distort - the HDD surface is managed differently than SSD cells). I have no idea how it would behave in the case of, for example: remapping (reading, writing, sector verification) where in SSD it reads a sector consisting of several cells and the write must be preceded by deleting the page (or block there - I don't remember - hence the name flash) and I do not know on what basis the firmware remaps the damaged area. Plus wear leveling (I think it's hardware supported) ...

Sorry, it is actually Silicon Power. An example model is SPCC Solid State Disk SBFM50.8. Each laptop has this brand, or a slightly different model. The surface scan result is always similar to the photo. After re-scanning, bad sectors are generally in the same places, but not always. I did not analyze whether it is the same every time. I have always used MHDD to diagnose HDDs and it did not disappoint me where there was bad sector actually other diagnostic programs were detecting it. There is no information on the reliability of the SSD on the MHDD website.

Hello.

I have Silicon Image SSDs installed in 10 laptops.

Unfortunately, during the tests with the MHDD program, bad sectors were shown. As the equipment was under warranty, I sent it back, but I got a feedback:

Quote:
SSD disks do not have physical sectors like HDD and therefore MHDD shows this information.
The website of the Silicon Power disc manufacturer also includes the following information:
https://www.silicon-power.com/web/FAQ
? Why does the computer detect a bad sector on the SSD? Is it damaged? SSDs do not get bad sectors since they have no physical sectors. Therefore, traditional hard drive detection tools are not suitable for SSD examination. ?

Of course, the complaint was not accepted. In fact, there is such information (currently not available, but it is here https://webcache.googleusercontent.com/search...IJ:https://www.silicon-power.com/web/FAQ+&cd= 1 & hl = en & ct = clnk = en & gl)

I wanted to get information from you whether the credibility of the MHDD program in the case of SSDs has nothing to do with reality?

For comparison, scanning chkdsk / r / f disks for empty areas did not detect bad sectors.

Topic summary

The discussion revolves around the use of the MHDD program for diagnosing Silicon Power SSDs, specifically regarding the detection of bad sectors. Users express concerns about the reliability of MHDD for SSDs, noting that it is primarily designed for HDDs and may misinterpret SSD firmware operations. The internal structure of SSDs, including wear leveling and remapping, complicates the accuracy of surface scans performed by MHDD. Participants recommend using manufacturer-specific diagnostic tools for better results and emphasize the importance of reading SMART data for SSD health assessment. The original poster mentions that despite returning the SSDs under warranty, the complaint was not accepted due to the discrepancies in diagnostic results.
