Recently my second "data" hard drive has started to disappear from windows. After rescanning the drive it re-appears with an autoplay box asking what I want to do with the files. I could be playing music from it when it's suddenly gone. I have all my important kids photo's on it that I have been trying to save to dvd, but half way or so through the burn the drive drops out and I get a burning error as there is nothing to burn. Any ideas out there please. SATA wires changed, drivers updated, virus scans done, but all to no avail. Running Win 7 Ultimate 64bit. TIA. Mark.
The first thing I would suggest is that you copy everything of importance to another (external?) HDD as it's quicker than burning.
Do you have any other backup of the data? If not you need to consider ensuring that all essential data on the PC is backed up.
If you have a HDD monitor installed it may well be worth checking the drive condition.
After you have saved your data you could run CHKDSK (this is done by right clicking the subject drive, select 'Tools' and click on 'Check Now' in the HDD checking area - follow any instructions).
This may also be temperature related; have you used a monitor to check drive temperatures?
It is an internal drive, maxtor (now seagate) so downloaded and ran seatools for windows and it passed all tests. I have tried backing it up to my main hard disk but it gets so far and then disappears again. Temperature was OK at time of checking. Tried a few backup tools with limited success.Changed the sata cables and power as suggested. I am looking at a sata to ide converter to see if that works long enough to save the data.
I have (I Hope) solved it. I disconnected the offending drive from the sata port and started the PC. I got a message saying that Boot Manager was missing. A reconnect allowed windows to start again. So I disconnected it again and re-installed windows and now all is fine (touch wood). It seems that the boot manager was on the data drive and windows on the other, a problem I have never seen before. Thanks for the help.
May take longer but try saving only a small volume of files at a time and see what happens. Obviously this would be easier between HDDs.
