Raw Value Byte : Later bad block countĢ57 -> 0x -> early: 0, grown: 257. If we indeed would assume 'early' defects based on for example Kingston documentation, we'd have: And I also think that if we assume 257 grown defects, then it's not reason to say "your SSD is just fine". Which is weird and not common practice in the past where manufacturers tended to hide such defects, so I doubt this.
Others suggested it indicates bad blocks detected while the SSD was configured at factory. What is this bad block count and is it early or later bad blocks? Your disks and their SMART data, to anticipate future errors.ġ. It's good practice to continue periodically checking Would specify for this disk, but your count of 72 is nowhere near it.Īll the other attributes are excellent, with absolutely no errors recorded. I'm not sure that this number is the same as ADATA When it reaches zero, the firmware may place the disk in a read-onlyĬrystalDisklnfo gives as threshold the number of 10 as the danger pointįor your disk. The number goes down, not up, as bad blocks are encountered. It's basically the number of good blocks that are available for mappingīad blocks, or in other words replace a bad block by one of theseīlocks. Value is decremented as the reserve block count diminishes over the The Attribute value is initially the total Reserve Block count. (Note that allīlocks, including reserve blocks, are in service at all times reserveīlocks constitute Flash memory space over and above the drive’s Provides a count of reserve (over-provisioned) blocks.
This Attribute is related to attribute 5: Retired Block Count. parameter indicates a number of reserved bad block handling.Īlthough this parameter is not considered critical by the most hardware vendors, degradation of this parameter may indicate electromechanical problems of the disk. Is named by CrystalDisklnfo as "Bad Block Count", but other sourcesĬall it "Reserved Block Count" and define it as: Your SSD is in excellent shape and has no problems. This question may appear to be a duplicate of Bad block count (early - later)?, but here I do not have early or later separation of data, so this is not an exact duplicate as such, and I have a larger scope. I tried submitting online query to Adata Support online but the web form errors out in the end Does it mean CrystalDiskInfo is interpreting the data and reporting it differently? Is that Bad Block Count really Bad Block Count? I would trust Adata’s tool as they know what they have designed? See the attached screenshot: AA Vendor Specified 72 72 10 Raw Value 101 Hex I downloaded Adata’s SSD Toolbox app and it reports these parameters as Vendor Specified. Maybe they are missing in the hardware itself. I have double checked with Adata SSD Toolbox but the parameters like Reallocated Sector etc are not reported. There’s no visible data loss as of now.Sometimes when copying a single large file, the speed drops to just 2 – 3 MB/s for a few seconds and then again jumps to 200 MB/s.
