Hello everyone, I have a question of MHDD

Hello, I have a question of MHDD, last year I bought a seagate 1000G hard disk, I used MHDD scan it, it has many green block, last month I used "erase waits time" function of MHDD to erase these green block, these green block disappeared, but I want to know does these erased block saved in G-list or P-list? And if I used this hard disk a long time, does these erased block will appear again?
Thanks very much!
Thanks very much!

bad sectors get added to the G-List and shouldn't get used again by the hard drive since its own operating system keeps up with them and the g-list table. The g-list can only hold so many then the "smart" gets tripped check the drive with hddscan to see the health of the drive with the "smart" button any yellow or red means its time to replace the drive.

@tulei:
In addition to the comments from networks, to give accurate answers to your questions about your specific disk, would need information that you have not supplied (except to say that MHDD will not add LBAs to the P-list).
To give you an example of some of the complexity - just because those slower LBAs are no longer slow, does not mean that they were definitely reallocated by the drive at all. If you had the full raw SMART data from before & after you ran MHDD, then you could check whether the value of attribute 5 had increased.
The exact meaning of an "erased block ... appear[ing] again" is not clear to me - I could guess at least 2 different interpretations. In any case, we can't know the future of your disk. Some answers would also depend on what caused your drive to have slow LBAs in the first place.
Don't rely on always getting a SMART warning before a drive fails, but as mentioned above, SMART might give you a hint that there's a problem, which you otherwise would not know until it was too late. Make sure you keep backups
