Bad sectors in dev sda... repairable?

[MacG32]

RT-AX86U running Merlin 3004.388.8_4 with amtm 5.2 , Skynet 7.6.4, YaxFi 4.4.5 dev. Found these is my reboot logs. Had a power outage and decided to reboot and check the logs.

Mar 31 10:27:56 kernel: blk_update_request: critical medium error, dev sda, sector 64
Mar 31 10:27:56 kernel: blk_update_request: critical medium error, dev sda, sector 128
Mar 31 10:27:56 kernel: blk_update_request: critical medium error, dev sda, sector 112
Mar 31 10:27:56 kernel: Buffer I/O error on dev sda1, logical block 10, async page read
Mar 31 10:27:56 kernel: blk_update_request: critical medium error, dev sda, sector 120
Mar 31 10:27:56 kernel: Buffer I/O error on dev sda1, logical block 11, async page read
Mar 31 10:27:56 usb: USB ext4 fs at /dev/sda1 mounted on /tmp/mnt/SD_32GB_USB.

Are these errors repairable? Is it a bad flash? USB drive bad? Any help would be appreciated. I'm really worried.

Your USB drive may have failed into read-only mode. Can you write anything to the drive?

Try this:

touch /tmp/mnt/SD_32GB_USB/testfile

Thank you for your help! It made a file called testfile in that directory. Is dev sda also the USB drive?

Yes. sda1 is the first partition on sda.

Run amtm and install the Disk check script (dc). Then reboot the router using the webUI and when it comes back up check the log file in amtm (dcl).

I removed the swap disk, uninstalled Skynet, reformatted the UBS drive, added the swap disk, and reinstalled Skynet. I installed Disk Check and rebooted. The log file came out clean.

Thank you so very much for all of your help! It's much appreciated!
