need some advise...
Environment :
AS62010T
Drive1 to Drive8 -> running in RAID6 mode
Drive 9 -> myArchive mode
Drive 10 -> myArchive mode
The NAS was powered on today, and i noticed later a "red light" at disk7.
Looking at "System Information" -> "Log" -> "Systemlog" it reports :
...date-time...[Disk Doctor]] Bad block scanning of Disk 7 has started
...date-time...[System] System starts
...date-time...[Disk] There is a data transfer error on sector xxx of the slot7 disk!
...date-time...[SNMP] Service started
...date-time...[SNMP] Service stopped
There is the Knowledge Base with some information :
https://support.asustor.com/index.php ... possible.

Code: Select all

For both transfer and CRC error, users are advised to have some more clarification to identify if the problem is caused by hard drives or NAS hardware.
Users can swap the error drive with another normal drive, and check if the log will report same slot error.
For example, Users found that the 1st slot reports transfer error, then he/she can shutdown the NAS,
switch slot 1 & 2, power on the NAS again, and check if the error moves to slot 2.
If the error moves to slot2, that means this drive might have some bad sector and users might want to replace it.
If the error stays with slot1, users might have to contact with Asustor support for further investigation.
At the moment, the "Bad Sector" scan is running at Drive7, however, before i'm going to replace the disk with a new one, I'd like to know, whether there are options to "heal" the disk without replacing it, or, whether there are other things recommended to do
PS: Besides the "Bad block" scan, which is running at the moment, i'm also copying the data to the myArchive drives (Updating backup).
Appreciate all ideas
Thanks !
