Ok, this is my first post here, although I have been a reader for the last year or so, and I really hope I am posting this is the right place. At the beginning of November I bought a WD 1Tb My Book and have been happily using it ever since. It has 3 partitions on it, one for ccc, one to use with Winclone, and one to store movies and music etc. I was accessing it last night and we had a power cut, this prompted the "Device Removal" message you get when a device is removed without ejecting. Since then I have not been able to use my "My Book", and all the data seems to have been wiped off it (This is no biggy as it is all backed up thank God!), however my macbook only recognised one partition when I remounted the drive in disk utility. I ran the verify and repair tools and no luck so I decided to erase, reformat and repartition it. This is where the fun starts! Since then disk utility is absolutely adamant, no matter how many times I erase/repair/partition the My Book, that it is actually in fact a 2Tb My Book. (I know it isn't as I bought the essential edition and not the mirror edition). When I partitioned the My Book so that there is only one partition taking up the whole space of the drive it first told me that there was 1024gb available (this is more than a 1tb should have [931gb] when you take into account the number of bytes), so realising there was something up I reformatted it and it is now telling me there is exactly 2Tb of space available. However, when I split the drive into my 3 partitions I get 1Tb of useable space and disk utility tells me that there is 1Tb of free space on the drive. The "Disk Description" in disk utility is "WD 10EAVS External Media" but when I google this I don't get any results other than a load of reviews for similar drives. Does anyone have any suggestions as to what I can do to "fix" this problem? Has anyone experienced it before? Is the hard drive corrupted? In which case do you think that I should return the drive? - it has a three year warranty. Any advice would be greatly appreciated.
