I didn't before, but I do now , I was only referring to the WD 3.5" External Hard Drives, Internals are great, especially the black labels, but my comments only come from Personal Experience of customers coming into/ringing the store looking for advice as to why the device they didn't buy from us is no longer working.
I have found this a bit of the reverse at work, the WD externals have issues, where the Seagate's are fine, but the Seagate internals have maybe more issues then the WD internals.
2.5" Range of both are fine....but also be careful of some of the WD's - the type that use's 1 USB cable. Here is a little story;
Customer came into the store with a WD 2.5" External they bought from DickSmith. They said it was making their system bluescreen etc, and took it back and had it swapped, but still the same issue. I plugged it into one of our store display pc's and sure enough it made the system crash, no idea why, my guess is too much current or something on the USB. Tried a brand new HP *Shudder* 2.5" External, still used 1 USB cable, and it worked fine on their system. They then took the WD back to DickSmith for a refund.
Oh btw, if anyone is looking for a job let me know, as we have a position available soon, must know computer software/hardware/troubleshooting/etc...sales experience would be very nice.
Edit:
My guess is you read that on Wikipedia? If not, sorry. In theory yes it does, in practicality no, it doesn't. Mind you, the file name can be up to, i think off hand about 128 characters, but if you start having folder within folder with long file names, then you can forget it.
