I have a Seagate Backup Plus Drive connected via USB to my Windows 10 computer. I use it to save my backup files from Macrium home. After my computer has been in sleep mode and then restarted, I find that backups usually fail. I can use windows explorer to look at the drive, and all is OK except for a few folders, and double-clicking one gives the message "S: is not accessible. The request could not be performed because of an I/O device error." Some other folders and files are available normally. Replugging the USB cable solves the problem until the next sleep.
What in the heck is going on? Is this Windows or Seagate?
When this problem first appeared, the S: drive would sometimes not be present in windows explorer at all after a sleep. Seagate told me to disable a power-saving option (where was that?) which seems to have changed the symptoms to the current situation.
Edit: 2/3/22: I/O error again. Tried:
C:\Users\rw>chkdsk /R s:
The type of the file system is RAW.
CHKDSK is not available for RAW drives.
Huh? Contrary to my claim above, I found that some folders are accessible but several others are not. Disk Management shows a healthy NTFS Basic Data Partition.
Replugged USB, and chkdsk is now running happily. ETA: 63:41:36 :(
I wonder if there is some kind of cache on the drive which gets corrupted during sleep cycles, leading to the problem. Restarting the drive then corrects it.
