I/O error 0x8007045d copying large folder between drives
Posted on 2011-04-20
I have a new 64 bit server running MS 2008 Server R2 with 8 Gb RAM, 120 Gb SATA SSD drive for the OS and a 500 Gb data dirve (3 SAS drives in a RAID 5). The LSI MegaRAID controller manages the drives.
My problem is when I copy a large folder (22 Gb) I recieve an error 0x8007045d: The request could not be performed because of an I/O device error. I copied the folder from an external USB drive with no problem but when transferring it between drives within the computer is when I recieve the errors. Copying from the SSD to the RAID it errored 111 times, when going the other direction it errored 41 times - different files, different file types and sometimes multiple times on a single file.
Don't want to put the server into production until I resolve this issue
