Yesterday I faced a problem with a 2TB WD Mybook: I could not copy files from this drive to another drive.
Windows CHKDSK did not report any errors, neither running SFC.
After about 20-30 seconds or so, the copy process is aborted with an error:
“A device which does not exist was specified.”
There were 6 (six) WD external drives connected. Under Windows Device Manager
under “Portable Devices” all 6 drives were listed.
under “WD Drive Management Devices” only 5 “WD SES Device” entries were listed.
This morning, after PC boot, I switched on that drive (only that drive) and copy process went fine.
The drive is listed under 'Portable Devices" and there is 1 WD SES Device entry.
Yesterday (with all 6 drives enabled): checking for update drives on this MyBook 2TB drive, WIndows report that the ‘best drivers’ were already installed (WPD FileSystem Volume Driver"
Windows Eventlog shows a boatload of errors:
EventID 505 - Completing a failed Read SCSI SRB request, or
EventID 507 - Completing a failed non-ReadWrite SCSI SRB request, or
EventID 502 - Completing a failed upper level paging read request
I counted 488x (!) yes 488 x within 1 second.
Now, I am used to these errors in the Windows eventlog. This has always been the case.
I have checked Internet, but no-one has a solution or could tell what the cause might be.
So far the drives worked nonetheless, so after many, many hours (=days) of trying to figure out what it is, I let it rest.
- I recently bought a WD 12TB drive, that being the 6th WD USB drive. The drive is NTFS formatted and contained 2 files, one for Mac one for Windows.
The windows version: “Install Western Digital Software for Windows.exe”
There is no explanation as to what this software contains, I did not install it.
The drive works well though.
After powering on the 2TB drive this morning, I immy noticed a few Eventlog errors.
a. the number of “WD SES Device” entries - do they have to be the same as the number of portable devices, i.e. in this case 6 WD portable devices, then 6 WD SES Devices?
If so, how to solve the problem in case there a difference?
b. any suggestions as to how to solve these eventlog errors?
c. what does the “Install Western Digital Software for Windows.exe” include?
d. should I try to install newer WD SES software? Or maybe “legacy WD SES Driver dated from 2011”
Hopefully someone has some answers on the above. I wonder whether I am the only one with these weird EventLog errors.
