Before everyone blames HUTIL v2.10, I thought I'd add my own experience with the F1 1Tb drives.
I bought five of them (5x 1Tb) here in the UK back in the middle of January, which all had serial numbers within a range of fifteen-twenty numbers of each other.
All five showed an ECC error on the M.C. test and four had also errors on the Surface Scan test. I low level formatted one of the drives that had both errors but it did not make a difference, so I couldn't really be bothered to go through formatting the other four.
I RMA'd within the week and took delivery of five new drives with totally different serial numbers, although still within a close range from each other (so I assume all came off the same batch).
Predicatbly, they all failed the M.C. test at which point in the I stopped the test, i.e. before the thorough Surface Scan as I knew I was not going to keep faulty drives (and honestly because I was out of patience with Samsung and the whole thing).
Full refund from retailer so all well there. Still put off though by having had to go through the very time-consuming hassle of funding, taking delivery of, installing, testing, communicating with tech support, repacking, resending, having to wait for refund for five faulty drives... twice... for nothing
Most interestingly however was that this was far from a academic issue for me; I could not get the harddrives to work with my Areca ARC-1231ML PCI-E raid controller card, not even when connected one by one, and the card configured for JBOD operation. The card recognised the drives alright but always hung on boot after the five-second countdown as part of its BIOS boot sequence and just before the O/S was supposed to load (If the drives were switched on in Windows Vista, they were visible in Disk Manager as long as they were connected straight to a SATA port on my motherboard).
I have no such problem with my two Barracuda 7200.10 750Gb drives, which makes me believe that these F1 HDDs suffer from more serious problems other than not being compatible with HUTIL v2.10.
I hope Samsung will sort this out and I am holding off buying other drives, at least till another manufacturer introduces a 3x333Gb platter product.
