MyBook Live Duo, 6 TByte, up-to-date firmware (as of 5/3/2012)
laptop, Windows 7 Pro 64-bit, up-to-date software (as of 5/3/2012), 8 GByte main memory, i7 processor
Device has 3 shares: 1 public, 2 private.
The initial month-long use of the original public share and my first added private share was fine.
Today, 5/3, I added a second private share. I can mount it fine, and windows uses M: for he first private share and R: for the second private share.
The laptop is an HP machine, with C: for windows, D: for RECOVERY, and G: for HP_TOOLS
The problem is that in “Computer” the original share, M:, is listed as 4.13 TByte free of 5.42 TByte (OK) but the new share, R:, is listed as a size and with free space equal to that of my laptop’s windows drive. Programs that examine the amount of free space on drives that they access get the wrong answer (for R: ) and may decide that they have insufficient space to perform operations (despite the file servers actual amount of free space of > 4 TByte).
