| 279681 | 2004-10-09 23:52:00 | my external hd is currently using FAT32 sometimes the external hd disconects from windows while writing files for no reson.. this doesn't happen a lot but when it does, it sometimes leaves junk that can't be deleted then have to run scan disk and all that to fix it if i change to NTFS, would this problem of undeletable junk go away when it suddenly disconnects? |

| 279683 | 2004-10-10 03:10:00 | oops..forgot to mention that the computer i'll be working with are either 2k or xp so i'm not worried just need to make the hd to handle file corruption better |

| 279684 | 2004-10-10 03:24:00 | Dont know if NTFS will fix this junk prob . Whats the external hdd? USB 1 or 2? Firewire? It might help if this hdd is bigger than 32gb which FAT32 cant go beyond . As NTFS can see more than FAT32 . |

| 279685 | 2004-10-10 04:26:00 | Is the external HDD USB powered, or does it use a power pack? 2.5" external USB drives can overload the USB power requirements causing them to disconnect, if they have no external power pack. 2 here have power requirements of 700 mA and 550 mA, at 5v. USB ports can supply a maximum of 500 mA reliably. |

| 279686 | 2004-10-10 09:46:00 | usb2 external hd 40gb its jz a case with notebook hd there should be enough power, but you can't plug in extra power it's one of those with two usb plugs which grabs some extra power from another usb port still not sure why sometimes the power get cut off/disconnect there was this file, when copied, it always make the hd to disconnect but when copy through usb1 (old comp) it works fine also when i just got the hd, keep disconnecting but after using for a while it worked smoothly... as if it got use to my comp?!?! bk to the original question... if ntfs won't solve the problem.. is there a way to completely stop disconnection from happening? |

| 279687 | 2004-10-10 09:55:00 | Multiple USB connections on a computer can still share only the 500 mA available . So its possible that the power is the issue . Look at the label on the HDD itself . How many mA at 5v is it rated at . If its over 500mA, then you may have a problem, if the USB ports on the PC are from a common motherboard hub . My portable drive has a socket for a power pack . The drive is rated at 550 mA and will not work on some PC's USB ports, not enough power . Another is rated 700 mA, and will not work on any PC's unless externally powered . Interestingly the light does not go out on the 550 mA HDD, the drive just refuses to work after a short time . Depending how hard its working . So I would suggest that its a power issue primarily in your case . Cases that accept external power are only about $65, plus a 5v adapter . |

| 279688 | 2004-10-10 18:35:00 | i'm pretty sure the hd doesn't require more than 500mA but now i'm starting to think that the usb2 on my comp isn't supplying enough power since it's onboard usb2 since these disconnections don't hapen a lot is there a way to stop the file corruption when it does?... don't really want to spend more money on another case... |

You are "pretty sure" . . . . . ? So, what does it say on the HDD itself? Never seen any with power drains below 500 mA myself . Any powered hub (be it on-board or external) will only reliably supply 500 mA, which is shared between all USB ports . Plugging in 2 USB cables to share the drain will only work if they are on different hubs . It also plainly indicates that the drain is over 500 mA, why else would they fit 2 plugs . If the drive is failing due to power draw, then there is nothing you can do to avoid data corruption . Apart from arranging a better power supply . |
