I have just been editing a wedding. I had encoded the footage using ProCoder, got to setting the menu with Workshop2 when the playback started stuttering, didnt think to much about it and closed the programme down. On rebooting my Icy box / Maxtor 250 Gig Diamondmax 10 was renamed local disc, when I tried to open it I got the message I:/ is not accesable. The file or directory is corrupted and unreadable. I tried a firewire and a USB2 cable with the same result. Tried on both laptop and desktop same thing. Cant rename the drive and in Disc management the drive shows as Disc I 233.76 GB online and healthy. Have I lost it?

If you have partition magic , start it up and see if you can 'undelete partition'.

When I right click/properties on the drive it says Type. Local Disc, File system. Raw, it used to say NTFS!!! I have Partition Expert. It wont give me any options on the disc at all. Out of frustration I clicked on delete, it did , now the drive doesnt show at all. I am going to try putting it in the desktop as slave and re formatting. Bloody nuisance, there is a lot of work on it. Will hold fire for a day or two to see if anyone has a solution. Thanks a lot.
Question for Harlequin/Gary. The drive read/write speeds are much lower when in the Icy box, ie 30 read, 26 write. When set as slave on the desk top they are an amazing (well amazing to me) 56 read, 70 write. Is this the norm? I have managed to access the drive on my desk top and reformatted, will try it back in the Icy box. If all is ok I have a lot of recapturing to do.

1. if you did't do anything else to the drive , except put it in as a slave , you 'MAY' have been able to 'undelete' it using partition magic.
2. I have an aversion to ICY BOX's , i'm on my second in less than a year , first one fried both a harddrive and its own controller unit in the housing.
3. I find that some external boxes don't give you full speed that can be obtained while the drive is an internal drive.
I always set external drives for 'performance' and not 'speed of removal'.
That can increase thruput.
You may also find that enabling write behind cacheing slows it down ..... weird , but it has been known to happen with some drives.
4. if you don't need it in the external enclosure , it may be better mounted internally , and i put my capture drive on a secondary pci controller card , which gives ata100 on a motherboard rated for ata33.

Thanks Gary.
Good advice. Will probably do as you suggest and put the drive in the desktop.

Same reply I posted in a similar topic!

This has happened to me twice in the last two weeks. Firstly on my internal SATA RAID array, and recently on an external Lacie triple interface drive.

I had a real gut hunch that the drives weren't faulty, so I bought another internal drive, swapped it for my system drive and built a clean copy of windows - Lo and behold I could see the drive fine. I'm sure it's something to do with the last 'auto update' of windows - as I never experienced these problems before.

I did run a chkdsk/f on the SATA drive too - something to do with the MFT being corrupt due to two versions of the name for the root directory existing or something - I did a lot of googling on this. (I did have some corrput directory entries which showed the symptoms of this - the chkdsk fixed them so I could delete them and then backup the drive properly).

When I reformatted the drive after backing up (to the Lacie!) - there were no reported bad blocks, so I still think they're fine.

I was getting a "the file or directory is corrupted and unreadable" error message btw.

I still can't read my Lacie drive on the PC I'm typing this on - but it works fine on my studio PC, which is still only running SP1.

My advice would be to get hold of a second drive like I did and try reading from a fresh build. Maybe you have one lying around? worth a few quid rather than possibly trashing data that you might not need to?? Let me know how it goes, as I'm still trying to get to the bottom of this one.

My other PC wont read the Lacie drive either, and that also got the last batch of 'auto updates' from Mr Gates & co.

2 possible fixes.

had the same problem twice. the first time i set the external as a slave and reinitialized it in disk management (administrative controls > computer management)
the second time that didnt work.... i downloaded a program called "file scavenger" a must have once you've tried it. Managed to retreive all but one single file from the disk, even though windows claimed it was empty and in RAW format. It gave me the same unreadable and corrupted message but file scavenger at least recovered my files so i could transfer them to a second drive.

hope this helps.

Well I finally sorted out my problems - had another disk go "corrupt and unreadable" after starting in safe mode - trying it and then rebooting.

Basically rebuilt windows. There was nothing wrong with any of the three disks, just something drastically wrong with my installation. How it happened? I don't know - possibly an auto update or something, as it was fine before and I never installed any new software recently.

Anyway - With the new disk I'd bought to test things with, I did the new build from scratch, and then ghosted it over my original build. So now I have a good ghost image that's been properly tested, plus a duplicate spare hard drive with the clean build (plus video apps & office on) for emergencies. The new build is performing faster than the bloated old one, and is much more stable.
