O.K. it started out i had problem with system restore not working,error code.I ran at elevated command prompt for both drives used chkdsk /f /r then dism /online /cleanup-image /restorehealth and scandisk.That seemed to fix the problem with system restore.
After checking the log for chkdsk and saw i had bad sectors on d: drive i believe this drive caused system restore not to work.
Now i use a program called Hard Disk Sentinel it says health on D:drive is 95% and performance is 100%.I receive on the main screen for the D: drive,there are 8 weak sectors found on the disk surface.They may be able to be remapped any time in later use of the disk.
When using program to run a surface test get error unable to lock the disk for exclusive use d:\error: access is denied,
Hard disk sentinel says to just continue ignore lock error.I read in a forum about fixingproblems seen in logs in program and after running chkdsk by reinitialise disk surface after a surface test,saying the sectors will be likely fixed and the errors will be removed health will increase.I know this process can wipe whole drive,it warns you of it but there is nothing on the drive now it's my second disk not primary.
What there help says about it:
Reinitialize disk surface -
Overwrites the disk surface with special initialization pattern to restore the sectors to default (empty) status and reads back sector contents, to verify if they are accessible and consistent.
Forces the analysis of any weak sectors and verifies any hidden problems and fixes them by reallocation of bad sectors (this
is drive regeneration).
Enables better use of the disk as after the test the spare area will be used instead of any problematic sectors.Very intensive and time-consuming
test, especially if the level (the number of overwrite cycles) is set to higher value.The simple version of this test is usually (incorrectly) called as low level format by.other tools. It can be effectively used to permanently destruct stored information (Navso P-5239-26 standard data destruction).
Each tests have different configuration options:
using Disk -> Surface test -> Reinitialise disk surface, the sectors will be likely fixed and the errors will be removed from the text description (and the health% will increase as well).Basically the "weak" sectors are not bad sectors. Most of the time, they even not related to hard disk problems as non-standard shutdown (reset/power failure) can cause this status for a particular sector.The drive marks these sectors as "pending" for reallocation. So on further disk usage these sectors may or may not be reallocated.Usually if you perform a Disk -> Surface test -> Read test, it properly shows the location of these sectors Also Disk -> Surface test -> Reinitialise disk surface test forces the hard disk to verify the status of the sector and re-allocate (to prevent further using of that sector) OR to remove this "pending" (weak) status if the sector seems to be usable.
Question is will this work to fix and improve the drive?Not an old drive.Only a year old Hitachi 1 TB SATA III 6gbs.Any Advice would be appreciated.TY
